Caloric content and composition of whey

Milk serum

is the liquid that remains after straining curdled milk during the production of cottage cheese or cottage cheese. Although, according to some consumers, whey from milk is an unnecessary liquid that can simply be poured out and forgotten, in fact it is a healthy drink that you can simply drink, use for preparing various baked goods and dishes (for example, you can make pancakes, pancakes with whey) , and also used for cosmetic purposes to improve hair and skin health.

Most whey from milk consists of water (more than 90% of the total volume), and the remaining few percent contains all the main beneficial components of regular milk. The chemical composition of whey is quite rich. It contains vitamins such as A, E, C, B vitamins, as well as macro- and microelements: potassium, sodium, calcium, magnesium, iron. Moreover, whey from cow's milk has a high content per 100 grams of product: potassium (161 mg), calcium (47 mg) and sodium (54 mg).

An interesting fact about whey: one liter of whey contains the daily value of calcium for an adult, as well as half the daily value of potassium. The proteins contained in whey from milk are much easier to digest than protein from eggs, so this fermented milk drink is useful for athletes.

Whey is a low-calorie product. 100 grams of whey contain only 27 calories.

No less popular is whey powder, which is produced using special equipment by simply evaporating regular whey from cow's milk. Dry whey from milk will retain all the beneficial properties inherent in liquid whey and is widely used in sports nutrition, in the production of baked goods, sausages, food additives, animal feed and in cosmetology. Also very popular among athletes is whey protein concentrate, which is separated from it using modern technologies (it is useful for the growth of muscle mass and is well absorbed in the body).

A person needs a varied and complete diet to maintain health and good immunity, allowing him to avoid troubles associated with diseases. Cottage cheese is considered one of the real storehouses of useful substances. It is rich in protein, iron and calcium necessary for the development of muscle tissue. Moreover, it is useful not only for adults, but also for children.

Even the healthiest product can cause harm to the body if the rules for its optimal storage are violated. Stale cottage cheese can cause indigestion, dysbiosis and even food poisoning - therefore it is extremely important to know how long you can store it and under what conditions without danger to health.

Beneficial properties of whey for the human body

Whey has a beneficial effect on the entire human body, helps strengthen the immune system and protective functions of the body, helps maintain the health of many organs, as well as skin and hair.

The liquid obtained as a result of souring milk, namely whey, is widely used by girls and women who know its rich medicinal and beneficial properties:

How is hair serum used? Since ancient times, women have known the effective power of whey on hair. It helps strengthen hair roots, as well as weakened hairs. Some girls use serum instead of shampoo daily to keep their hair beautiful and strong.
Milk serum for facial skin. There are many recipes for creams, masks and facial scrubs based on milk whey that can effectively clean pores, smooth out wrinkles, and make skin healthy and more youthful in appearance.
Using whey for dieting and weight loss. Whey milk is widely used in many diets due to its beneficial properties and low calorie content. It is used as the main product on fasting days to cleanse the body of waste and toxins.

Contraindications to the use of whey from milk

To a greater extent, whey is a beneficial product for human health, but in some cases individual intolerance to it (in particular to the lactose contained in it) is possible, and you should abstain or reduce the amount of its consumption in the following cases:

The storage conditions have been violated or the expiration date has passed (this is a perishable product with a high content of lactic acid bacteria).
Drinking large amounts of whey from milk at one time can lead to diarrhea.

How to drink whey correctly?

It is better to drink whey from milk on an empty stomach before meals, and, if desired, you can add various spices, herbs (basil, parsley, dill), add salt or add sugar to give it an original taste. Whey also goes well with many berries and honey, when mixed with which you get a rather tasty and pleasant drink.

The average adult should not drink more than 3 glasses of whey per day. You can divide the “doses” of whey intake into 3 times (breakfast, lunch and dinner) and drink it before meals.

How can you make your own whey at home?

You can easily make healthy and natural whey yourself at home. To do this, you will need regular cow's milk, which must be left for a day in a glass container at room temperature so that it sours and you get yogurt. Next, the yogurt is poured into a saucepan and put on the fire, heating it well (but not bringing it to a full boil) until clots of cottage cheese appear on the surface, after which we remove it from the heat and let it cool completely. Finally, line a colander with gauze and strain the curdled milk, ultimately obtaining homemade cottage cheese and high-quality whey from milk.

Note: whey from domestic cow's milk will be more useful, since such milk is completely natural and has not undergone any additional processing.

How to store whey at home

Storing whey at home is no different from many other dairy products. It is better to store it in a glass container in the refrigerator, but do not forget that it cannot be stored for a long time and is a perishable product.

Sometimes on the Internet you can come across such a curious question: is it possible to freeze whey? The answer is yes! The main thing is not to use glass containers for this (it may burst), but use plastic bottles or ice trays.

In conclusion to the article, it can be noted that such a seemingly useless product as whey should not stand out in any way, but in fact it is a very healthy fermented milk drink that has a beneficial effect on the entire human body and is practically harmless for adults and children. We leave our reviews and advice on how whey is useful, as well as its benefits and harms for the human body, in the comments to the article and share it on social networks if it was useful to you.

In order to improve consumer properties and increase shelf life, sucrose is added to condensed whey in an amount of 12.5-30%, which makes it possible to obtain concentrates with a mass fraction of dry substances of 52.5-90% based on solids condensed to 40-60%. Sucrose is added to the finished product after thickening, the mixture is thoroughly mixed and cooled to 6-10 °C.

A technology has been developed for enriched whey concentrates due to the fermentation of lactose (30, 40 and 60% of dry substances) and its hydrolysis (40% of dry substances, degree of hydrolysis of at least 50%).

By targeted processing and the addition of fillers based on condensed whey, it is possible to obtain valuable food products and feed semi-finished products: pastes, cheeses, creams, sausages, noodles, fudge, honey surrogates, feed blocks, lick salt blocks, etc.

Whey cheese

is a whey concentrate containing up to 80% dry matter and a characteristic odor due to the caramelization of lactose during high-temperature processing of the cheese mass. The production of the product is common in Norway under the name mesmor.

Whey pastes

prepared on the basis of whey concentrates with the addition of fillers and aromatic substances. In Sweden, they produce myzost paste with a whey solids content of 75%, fillers: cream and beet sugar (10-12%). The technology for Kendylak cheese paste, developed at VGTA, provides for whey thickening to 60-65%, partial crystallization and separation of lactose (20-25%). The product contains up to 10% protein and has an acidity of 300ºT, recommended for use in baking.

Condensed whey in blocks

can be obtained by thickening it to 85-95% of dry substances, followed by cooling in molds, as well as directed heat treatment to obtain a coagulation-crystallization structure, or by adding fillers (flour, bran, calcium and sodium salts, methylcellulose, lactic acid, etc.) . Block concentrates with a dough-like consistency can be formed at a dry matter concentration of 48-52% by structure formation by cooling and mechanical processing (developed by the Siberian branch of VNIMI).

Condensed whey can be widely used for the production of processed cheeses, ice cream, in bakery and confectionery industries, other food products, milk replacer formulations and feed starters.

Whey powder.

Drying whey allows you to use all its components and store the hermetically sealed product for an almost unlimited time. Whey can be dried using one of the methods used in the dairy industry: spray, film, foam, sublimation, thermoradiation, etc. Combining the process of drying condensed whey with crystallization of lactose and granulation of the resulting product is promising.

Whey, as an object of drying, is characterized by a significant amount of moisture (about 2 times more than in natural milk), which is more energetically associated with dry matter, which affects the performance of dryers.

The kinetics of whey drying includes three main periods - increasing, constant and decreasing drying rates. Increasing the dry matter content in whey before drying due to thickening increases the amount of bound moisture, which affects the drying speed:

change in drying speed, %/min 10.5 5.5 3.8 2.0 1.5

During the first period of increasing drying speed and constant temperature of the material, free moisture is removed - simple evaporation occurs. In the second period, at a constant drying rate and increasing the temperature of the material, osmotically bound moisture is removed. In the third period of decreasing drying rate and the material temperature approaching the isotherm of the heating zone, adsorption-bound moisture is removed.

Can I keep it in the freezer?

Its shelf life in the refrigerator cannot be compared with its shelf life in the freezer. Temperatures below zero significantly slow down the metabolic rate of the lactobacilli living in cottage cheese, due to which it spoils much more slowly and, therefore, is suitable for consumption for much longer.

Cottage cheese frozen at -35 degrees Celsius immediately after production can remain usable for up to three weeks. During this time, even a small family can eat several kilograms of it - therefore this method is the most optimal if it is necessary to preserve a large volume of it.

Unfortunately, the method also has its drawbacks. Before eating, the curd mass must be properly defrosted - and this process is quite lengthy. If you want to try this dish, it will be impossible to satisfy your desire right away. It can only be defrosted in the refrigerator, which takes ten to twelve hours. When defrosted at room temperature (within 4-5 hours), it loses its structure and taste, and is only suitable for baking or other methods of cooking through heat treatment.

Whey beneficial properties

The serum is able to restore the balance of water and salt, which helps relieve swelling. In addition, it allows you to cleanse the body of toxins. It is enough to drink just one glass of whey per day on an empty stomach.

The substances that whey is rich in cleanse the body of bad cholesterol, which means that harmful plaques will not be deposited on the blood vessels.

The product is indicated for depression. It turns out that the serum contains components that negatively affect the production of so-called stress hormones and promotes the production of the “happiness” hormone serotonin.

The benefits for the digestive system have already been mentioned at the very beginning of the article. Since it contains beneficial bacteria, it is useful for those who suffer from gastritis and colitis, and frequent constipation.

For those who want to lose weight, you can also use serum to normalize weight. Because it can reduce appetite, and the rich set of nutrients can help you stick to your diet without harming your health.

The beneficial properties of this dairy by-product were appreciated by almost all beauties. It has an excellent whitening effect and is useful for oily and normal skin. To enhance the effect, you can add a few drops of lemon juice to it and its whitening effect will increase.

The serum will help remove dryness and reduce pain from sunburn. You can apply it to your skin or add two liters to your bath when taking a bath.

Burdock decoction mixed with whey perfectly restores and strengthens hair. Try washing your hair once a week and you will soon see results.

Whey benefits

Whey, which many people discard after making cottage cheese, can actually provide great benefits to our body. It contains not only a complex of the most necessary minerals, but most importantly – protein. Whey consumption:

Creates muscle strength; Provides vital energy; Improves immunity; Prevents diseases such as cancer and HIV; Lowers blood pressure to healthy levels without side effects, unlike blood pressure medications; Reduces the risk of thrombosis, thereby helping prevent heart attacks and strokes; Improves prostate health and prevents prostate cancer; Promotes the growth of healthy intestinal bacteria and inhibits harmful bacteria; Cleanses the bladder and helps prevent bladder infections; Corrects hormonal imbalance; Slows down aging; Promotes weight loss; Improves digestion, similar to dietary fiber; Supports healthy kidney function.

Many athletes, especially bodybuilders, use supplements every day to build muscle mass, not paying attention to such a useful product and forgetting that synthetic drugs are harmful to health. Whey is a natural product and has no side effects.

The benefits of whey.

Whey consists of 94% water and 6% vitamins and microelements. It is because of this 6% that it is a very useful product. They contain more than 200 biologically active substances, each of which has its own effect on the body.

This includes vitamins A, B, C and E, calcium, phosphorus and magnesium. Per 100 g of whey there are 0.8 g of protein, 0.2 g of fat, 3.5 g of carbohydrates, and the nutritional value varies from 18 to 30 kcal.

It is necessary to say something about proteins separately. The fact is that they are better absorbed by the body than their counterparts in the same eggs. In addition, whey proteins are very similar in amino acid composition to the proteins found in muscles. Because of this, this product is used to create protein concentrates that contain essential amino acids for sports and baby nutrition. As you can see, whey contains very different benefits and harms.

In addition, it contains high levels of lactose. The latter reduces the processes of gas formation in the body, helps with the restoration of intestinal microflora and normalizes metabolism.

Whey will be useful for people whose work involves active brain activity. Choline contained in this product helps in the production of phospholipid - lecithin, which improves memory and reduces the risk of atherosclerosis.

If you have a stressful period of life associated with constant stress and worries, then be sure to drink whey. Lactoalbumin, influencing the functioning of the adrenal glands, reduces the production of cortisol, the stress hormone, while increasing the level of the joy hormone, serotonin. One drink and all your problems will no longer seem so terrible to you. This is a real scientific fact obtained by studying the benefits and harms of whey.

Those who care about the beauty of their body should also pay attention to this product. The biotin included in its composition improves fat and protein metabolism and contains sulfur, which is necessary for healthy skin, hair and nails. In addition, potassium, which is also abundant in whey, reduces or prevents the occurrence of cellulite. In addition, it removes all waste and toxins from the body and eliminates swelling, thanks to its mild diuretic effect.

Whey should definitely be included in the diet of people losing weight. Despite its low calorie content, it causes a feeling of satiety and reduces appetite. Sweet whey will be an excellent alternative to any other sweets.

Whey harm

The only reason not to use whey is individual lactose intolerance. People with this problem may have an allergic reaction, swelling, diarrhea, and flatulence.

People who suffer from frequent diarrhea may have an intestinal disorder.

Another danger is improper storage. This is still a natural product with live lactic bacteria, which means it is a good environment for the development and growth of pathogenic bacteria, which can cause poisoning.

Despite the contraindications, whey is a very healthy and tasty drink that can be used in dozens of ways. Don't forget to include it in your diet!

How and how long to store whey

The remaining whey after preparing homemade cottage cheese or soft cheese must be stored in the refrigerator. The best container for storing it is an enamel or glass container with a lid. The shelf life of such serum is a maximum of 5 days.

But you shouldn't throw it away. It is not suitable for drinking, but is quite suitable for cosmetic procedures, making dough, sauces, and soup. The maximum shelf life of the serum is no more than 15 days.

There is no need to freeze the serum. When frozen, all its beneficial properties are lost, and it no longer provides any benefit to the body.

As for whey purchased in a store, when storing it you need to follow the manufacturer’s recommendations. When purchasing, pay attention to the composition of the product. In general, there should be nothing in it except the serum itself.

The timing and temperature conditions are usually indicated on the packaging. There may still be a deadline for implementation. These are different things. The closer the end date of sale, the less useful substances it contains and the greater the likelihood of poisoning.

Shelf life of homemade whey. How long to store homemade whey?

Usually, the serum that is sold in the store has a shelf life of two days. But homemade whey can be stored for up to two weeks without problems. Naturally, it should be stored in the refrigerator, preferably in a glass, not plastic, container with a lid. However, “can” does not mean “necessary”. It is better to consume it while it is fresh, as some of the beneficial properties of whey wane over time.

Oddly enough, homemade whey can be stored longer than store-bought whey. Unlike store-bought, it can be stored for up to two weeks in the refrigerator. But this is if you didn’t buy it at the market and you don’t know where and how long it was stored, but you made it yourself (for example, it was left over from making homemade cottage cheese).

How to make whey

Whey can be made from fermented milk, kefir, curdled milk, fermented baked milk or yogurt.

To make whey, pour raw milk into a clean glass jar. Cover the jar with a lid (coffee filter or clean cotton cloth) and leave it at room temperature for 2-3 days until it sours. To speed up the process, you can add a little lemon juice. Then the milk will sour overnight.

Pour the sour milk into a suitable pan (not aluminum) and place on the lowest heat. Heat gradually without letting it boil. Otherwise, the cottage cheese will be very hard, like rubber.

You will know about the formation of curd by the separation of whey and the formation of a curd mass.

To separate it, place a colander on another pan and cover it with gauze. Drain the curd.

Take the gauze and twist the edges. Hang it up with a container into which the whey will drain. As soon as liquid stops dripping from the curd, put it in the refrigerator and pour the whey into a jar or pan.

How to store homemade whey

Many housewives prepare this product themselves. It remains after making homemade cheese. The question arises: how and where to store the whey from cottage cheese?

In the absence of a refrigerator, the best place to preserve the quality and nutritional properties of the product is the cellar. Optimal conditions are observed here - humidity and temperature, there is no sunlight, which is important to avoid fermentation processes. The length of time to store homemade whey in the cellar is up to 3-4 days.

If this is not possible, then whey can be stored on the balcony, at an air temperature no higher than 10°C, but not lower than zero. To do this, pour it into a clean, opaque container and leave for up to 3 days.

At room temperature, the product spoils quickly, but there is a way to keep it fresh a little longer. To do this, cover the whey with clean gauze so that it sinks into the liquid. Moisture will evaporate from the fabric and thereby cool the contents.

The length of time the curd whey is stored in this way at room temperature is up to 2 days away from direct sunlight. It is best to take the container to the pantry.

Whey how to use

In addition to the fact that whey can simply be drunk as a healthy and healthy drink, it is also used for a variety of purposes.

It can be used for:

Soaking legumes and grains before cooking to reduce the content of harmful substances and improve the digestibility of beneficial ones;

Preparation of dough for various baked goods, including pancakes;

Making soups by replacing bone broth;

Various cocktails;

Fermentation (fermentation) of vegetables and fruits;

Cosmetic procedures;

Pets;

Treatment and watering of plants.

It can be drunk pure or by adding honey, sugar, salt, fruit and vegetable juices.

Include this dairy byproduct in your diet. It will only benefit our health.

What is serum

This is a by-product that is obtained during the production of cottage cheese, cheese, milk or casein. The milk is subjected to significant heat treatment (or simply left to sour), during which the liquid is curdled and then filtered through special structures.

The drink is not a modern innovative food discovery. It has been used since the time of Hippocrates. The serum was used to treat diseases of the skin, liver, respiratory system, dysentery, kidney stones, poisoning and stool disorders. Doctors prescribed natural medicine to each patient as a general strengthening and tonic.

Modern medicine abandons such practices and is guided by evidence-based medicine. The benefits of whey have been embraced by food companies, which produce millions of batches of dairy products every day.

The cosmetics industry is not far behind. Extracts or whole serum components are added to face, body, hair and cuticle care. Manufacturers claim that the product qualitatively nourishes hair/skin and may well qualify as a multifunctional product on your cosmetic shelf.

Shelf life

Natural cottage cheese is a perishable fermented milk product. The timing of its implementation is regulated by sanitary standards and GOST. Cottage cheese is stored in the refrigerator from 2 to 14 days, depending on packaging and pre-treatment. If this period has expired, the product must not be eaten!

Interesting: Is it possible to store boiled beets in the freezer?

Before placing the cottage cheese in the refrigerator, wrap it in parchment or foil. You might also try placing it in an enamel container with a tight-fitting lid. A product that has been stored for more than 1 day is best cooked and used for dumplings, casseroles, cheesecakes, pancakes, etc.

Slightly weathered cottage cheese can be refreshed by adding sour cream, but after that you cannot store it - you need to eat it right away. If the cottage cheese tastes a little sour, this is acceptable, but it is advisable to use it for heat treatment. If bitterness appears, the cottage cheese has hopelessly deteriorated.

Making whey at home

The human body simply cannot digest lactose, therefore, as a protective reaction, it turns into intolerance. Symptoms of intolerance are the body’s original signals for help. Galactose is the most harmful and dangerous sugar. The component interferes with the normal absorption of Calcium (K), accelerates the aging process and triggers irreversible processes in the brain.

Independent nutritional studies have confirmed the lack of essential vitamins in low-fat dairy products. Health, strengthening the muscle corset and growth vitamins are nothing more than a marketing ploy, and not real benefits. Moreover, low-fat whey is able to “eat” other vitamins that are concentrated in the human body.

Does the serum have any benefits?

There definitely is! Milk and its derivative products are designed by nature to feed healthy offspring. They contain vital nutrients, vitamins,... Moreover, there is not a single product or mixture that could replace the benefits of milk for offspring. There is a clear analogy with human lactation. Indeed, mother's milk contains all the necessary elements that the baby needs. No store-bought formula or extra-class fruits/vegetables can compare in nutritional value and benefits to breast milk. But here’s the paradox: absolutely all living beings (except humans) feed on milk only at the primary stage of growth.

A human baby drinks its mother's milk until it is 1-2 years old; a calf feasts on the white foamy liquid until it reaches maturity. In the active phase of growth, everyone switches to plant/synthetic food, breaking the tender connection with the mother, which is cemented precisely by milk.

An adult does not need dairy food components at all. Their absence will not affect the quality of life or health in any way.

At the moment, there are no dairy products in the world without hormones (harmful for the adult human body). Even livestock, which feed on organic grass in the meadow and live according to all quality criteria, produces products that are stuffed with hormones. Scientists have identified more than 60 dangerous hormones that are similar to anabolics (substances that bodybuilders use to quickly gain muscle mass), as well as testosterone, insulin, progesterone and stimulants.

Quitting milk and its derivatives is a choice in favor of health and a quality life. Make the right decisions and be healthy!

Not many people know about the beneficial properties of whey and consider it useless, but in fact this fermented milk product has many useful and medicinal properties, so let’s look at how whey is useful for the human body and how it can be used and taken.

Caloric content and composition of whey

Whey is the liquid that remains after curdled milk is strained during the production of cottage cheese or cottage cheese. Although, according to some consumers, whey from milk is an unnecessary liquid that can simply be poured out and forgotten, in fact it is a healthy drink that you can simply drink, use for preparing various baked goods and dishes (for example, you can make pancakes, pancakes with whey) , and also used for cosmetic purposes to improve hair and skin health.

Whey is a low-calorie product. 100 grams of whey contain only 27 calories.

Of course, storing whey in the refrigerator is easy and convenient, but what to do if it suddenly breaks down, or your housing office is carrying out maintenance work, and therefore the lights are turned off? If we are talking about homemade whey, you can use lemon juice. To do this, while still in the cooking process, add the juice of one lemon to a boiling pan with yogurt, then turn it off and leave.

Then proceed as usual: using a sieve, separate the curds and the whey itself and strain. This serum is very rich in vitamin C and will be stored much longer than usual (tested!)

How to store whey? If it's summer outside, you can try grandma's method: place a jar of whey in a wide enamel basin or bucket of cold water, wet a gauze napkin, cover the jar with it, and dip its ends in cold water. The water from the gauze will begin to evaporate and will cool the product, preventing it from spoiling for several days.

It is best to store the serum in glass or enamel containers: firstly, this way the vitamins are better preserved, and secondly, this way it will not spoil for a long time. Just be sure to put it somewhere cool and dark.

If the time of year is autumn or early spring, then you can put the whey in an enamel pan on the balcony, or put it outside the window, placing the jar in a specially designed container for storing food. In winter, the whey should not be stored in this way under any circumstances: the product will freeze and completely lose its beneficial properties.

Serum storage does not involve sunlight, freezing, or stuffy rooms. Therefore, in winter it can be stored on the window in the kitchen, not forgetting to first pour it into an opaque container with a lid, preferably enameled. You can pour the whey into a thermos and place it in a cool, dark place, but this method is not entirely suitable for the summer heat.

But in cooler times of the year, this method can keep this product fresh for a week. And, of course, if you are a rural resident, then the cellar is the best place to store dairy products! This is where the optimal temperature is, allowing you to fully preserve the taste and quality of natural whey.
