Whey - description, composition, calorie content and nutritional value

Serum is also a cosmetic product: it is used to make nourishing cocktails for the skin, lotions, baths and masks. The liquid promotes cell renewal, normalization of metabolic processes, removal of toxins and biological decay products. This natural raw material is included in natural cosmetics that care for the skin, smooth out wrinkles, strengthen hair, and produce a rejuvenating effect. According to legend, Cleopatra's famous baths contained serum.

What is whey

Whey is a by-product of the curdling of sour milk, which is obtained in the manufacture of cheeses or cottage cheese. Description:

opalescent liquid;
taste - sour (when pressed cottage cheese) or sweet (when hard cheeses are made);
color – light yellow.

A substance corresponding to the specified characteristics is formed in milk according to the following mechanism:

milk microorganisms secrete lactic acid;
the acid reduces the pH level to 4.6;
In an acidic environment, casein, which is a milk protein, coagulates.

The resulting precipitate is filtered, and the liquid part is used as:

drink;
component of care procedures;
ingredients for cooking;

Since casein, fats, and sugars go into the cottage cheese, the liquid part includes water-soluble components:

albumin (protein);
riboflavin (B vitamin);
mineral salts (potassium, calcium, etc.).

All contained substances are valuable for the human body, since albumin is a building material, riboflavin helps strengthen the nervous system and immunity, mineral salts are necessary for bone and muscle tissue.

Where does whey come from?

When we add starter (strains of pure cultures of lactic acid bacteria) to milk, the process of lactic acid fermentation begins, as a result of which part of the lactose, milk sugar, is processed by lactic acid organisms into lactic acid. Under the influence of this acid, the milk protein casein changes (coagulates). Water-insoluble casein particles are formed, which form the network of the milk clot. The cells of this mesh capture globules of fat and other components of milk. The milk clot system is very unstable. Under the influence of temperature, mechanical stirring, pressing, it can be destroyed, in this case, water-insoluble particles precipitate, the product separates into the milk clot itself and a yellowish-greenish liquid, whey.

Mechanical action is not necessary to separate whey. Coagulation-type structures, such as a milk clot, are prone to syneresis, that is, spontaneous compaction, compression, which contributes to the pressing out of whey (for example, when opening a jar of sour cream, you can notice that on the surface the consistency of the product is slightly more liquid, here it is, the phenomenon of syneresis in action ).

Now let's try to translate all this into understandable culinary language.

Various fermented milk products differ in appearance, consistency, and taste. These differences are determined by the nature of the milk clot from which they, in general, consist. At the same time, the taste and consistency (structure) of the clot itself depend on:

on the type of starter (those microorganisms that are part of it),
on the quality of milk (acidity and ability of proteins to retain moisture),
intensity of impact on the clot.

Products such as yogurt and sour cream have a smooth, delicate structure. Their texture is quite uniform. A small amount of whey is acceptable. However, when too much whey is formed, this indicates that the preparation technology was violated, or the quality of the milk raw materials left much to be desired.

Cottage cheese and cottage cheese, on the contrary, have a denser consistency. Whey separation is one of the stages of their preparation. Fermented milk starter in the production of cottage cheese and soft cheeses such as Ricotta produces sour whey, it is also called curd whey. In addition to fermented milk starters, rennet is used to form curd and cheese grains (hard cheeses such as Cheddar, Mozzarella, etc.). In this case, sweet whey or cheese is obtained. It is noteworthy that the composition of both types of whey is almost identical.

Benefits of whey for the body

Positive effects of systematic use:

cleansing – removal of salts of heavy metals, waste, toxins;
normalizing – the functioning of organs such as the liver, kidneys;
anti-inflammatory – spreads to the epidermis, mucous membranes;
strengthening – bone and muscle tissue;
immunostimulating;
improvement of blood circulation and metabolic processes;
replenishment of vitamin and mineral reserves;
maintaining elevated mood levels;
antioxidant;
prevention of early aging;
improvement of memory, concentration;
decreased appetite;
influence on cell growth and regeneration;
increased performance.

Let's take a closer look at the positive properties of the product for different categories of people.

Compound

Whey protein is very similar in amino acid composition to human muscle tissue.

It contains essential amino acids such as:

Valine is one of the most important components for the growth of body tissues, a source of energy in muscle cells. Improves muscle coordination, reduces sensitivity to pain. Participates in nitrogen metabolism in the human body. Protects the myelin sheaths of nerve fibers (damage to them can lead to the development of multiple sclerosis).
Leucine is an essential amino acid that is not produced in the human body. It is a source of energy, necessary for building muscle tissue, and is involved in the metabolism of proteins and carbohydrates. Leucine is also necessary for the synthesis of hemoglobin.
Isoleucine – participates in energy metabolism. With its deficiency, carbohydrate metabolism is disrupted, and insulin deficiency occurs.
Methionine - serves as a source of formation of choline (a precursor of acetylcholine, which serves for the transmission of nerve impulses) and phosphatides, which are important in metabolic processes.
Cystine is necessary to maintain the activity of the hormones vasopressin, oxytocin, somatostatin, and insulin. Participates in the formation of keratins.
Threonine – necessary for the synthesis of collagen and elastin. Participates in lipid and protein metabolism, increases the activity of the body's defenses, and helps reduce fat deposition in the liver.
Lysine – helps lower triglyceride levels in the blood. Lack of the substance leads to the development of immunodeficiency, increased fatigue, weakness, anemia, hair loss, and slow growth.
Tyrosine is necessary for the production of biologically active substances, thyroid hormones. Helps reduce fat deposits in the body, improves the functioning of the adrenal glands, pituitary gland, and thyroid gland.

Whey protein is a product that may contain other additional components:

emulsifiers (soy lecithin) serve to obtain the required consistency of the product;
flavorings and dyes;
sweeteners (sweetener sucralose and others);
acidity regulator (malic or citric acid);
malt extract and other ingredients.

Dosage and how to take it

Since the serum is an auxiliary measure for the treatment of diseases, you should not expect a dramatic improvement in health after two or three days of use - the minimum course is three weeks. Unlike other methods of therapy, the drink allows you to achieve a positive and long-term result due to the natural composition.

According to data from most analyzed sources, it is enough to take one glass of this product daily before breakfast. This will help ensure vigor and energy for the whole day. If we talk about using whey for the purpose of losing excess weight, there are special weight loss systems that involve a smooth transition to this product, and then a gradual return to the usual diet. In this case, to ensure a full supply of vitamins and minerals per day, you need to drink one and a half to two liters of whey.

How to drink

It is best to drink whey in the morning, before breakfast. This will start the metabolism and give the body strength. You can combine it with various berries and fruits, oatmeal. To make the taste of the dish more pleasant, add a little honey to it.

I do not recommend drinking more than 2-3 glasses of the product per day, as this may cause a laxative effect.

Medicinal properties of whey

In fact, whey is a therapeutic agent that helps normalize blood pressure, which is important for people suffering from hypertension, and reduces the risk of developing diseases such as:

osteoporosis;
atherosclerosis;
rheumatism, etc.

There is evidence of the product's effectiveness against the following diseases:

dysbacteriosis;
food poisoning;
chronic constipation;
diabetes;
chronic gastritis;
pancreatitis;
enterocolitis;
associated with disorders of the liver and kidneys;
ischemia;
angina pectoris;
hypertension;
impaired cerebral circulation;
cystitis;
herpes.

In this case, drinking one glass of drink in the morning on an empty stomach should not be the main means of treatment. In the presence of these diseases, the serum can be used as an auxiliary element of a complex of therapeutic measures, and before use it is better to consult a doctor.

The use of serum in therapy is due to the presence of the following medicinal properties of the product:

regulation of intestinal microflora, slowing down the process of gas formation;
removal of excess fluid;
strengthening the immune system;
reducing the secretion of hydrochloric acid (useful for older people);
activation of fat and carbohydrate metabolism (important for obesity or a sedentary lifestyle);
normalization of the number of glucose units in the blood;
improving the functioning of the cardiovascular and nervous system;
relieving swelling;
eliminating headaches;
improving the walls of blood vessels (varicose veins).

When studying the information presented below about the benefits for certain diseases, you should note that you should take the drink only after prior consultation with your doctor or therapist.

For joint diseases

Traditional medicine provides a simple remedy for treating and preventing the development of diseases associated with joints:

the whey is heated to forty degrees Celsius;
moisten a gauze bandage in the prepared liquid;
apply a compress to the sore spot, cover it;
keep it all night.

Also, if you have arthritis or arthrosis, you should consume at least five hundred milliliters of whey orally during the day in a course lasting two to four weeks (determined by your doctor). As a preventative measure in this case, one glass of the product is enough.

For gout

Since the serum helps remove uric acid salts from the body, relieves swelling and improves the functioning of an organ such as the kidneys, it is worth noting its effectiveness in the fight against gout. For this disease, you should drink one hundred milliliters of this drink daily.

Dosage for diabetes

It was mentioned above that in case of diabetes mellitus, the daily amount must be divided into three doses, drunk before breakfast, lunch, dinner, each time diluting the required amount with boiled water in a ratio of 1:2. Serum should not be the main therapeutic agent in the presence of this disease, because at the moment there are no exact scientific facts about the effect of such a product on the body - studies are being conducted and there is only isolated data. Scientists from Israel were able to establish the following positive effects of using the serum:

improved insulin production;
decrease in the number of glucose units in the circulatory system.

For gastrointestinal diseases

For diseases associated with the gastrointestinal tract, the dose of serum depends on the nature of the deviation/rules of use:

chronic constipation / three hundred milliliters of a drink made from carrot juice and whey, proportion 1:1, drink before breakfast for a month and a half;
impaired digestion, appetite disturbance/six hundred milliliters during the day, course – ten days;
gastritis, pancreatitis, stomach ulcer/six hundred milliliters per day, course duration - one month.

To cleanse the intestines of waste and toxins, it is better to add table salt to the whey (one tablespoon per glass of liquid).

Against cough

Whey in its pure form is a powerful tool for the prevention of colds and viral infections, and if a cold does occur, the by-product from the production of cottage cheese can cope with the symptoms no worse than hot milk. To eliminate a cough with heavy sputum discharge or to cure a sore throat, serum alone will not be enough.

One of the effective treatments for bronchitis is a decoction of wheatgrass root, prepared using whey instead of water: one tablespoon per half liter of liquid (the prepared mixture is then boiled). One hundred milliliters of this product three times a day before meals is used to treat:

diseases associated with the throat;
cough.

Within two to three days you can feel a noticeable improvement in your well-being.

For gastritis

It is recommended that in the presence of gastritis with low acidity of gastric juice, adhere to the following rules for using the serum:

before eating;
in thirty minutes;
five hundred to six hundred milliliters divided by three to five times.

The product helps relieve internal inflammation, stimulates the gastrointestinal tract, which is important for gastritis.

The serum helps get rid of flaking skin both on the face and at the roots of the hair.

Whey Protein or Protein: Pros and Cons

Mom's opinion

Whey protein is made from sour milk without casein. The ultrafiltration method stops most of the large molecules of fats and other things on the membrane. What remains is water with small whey proteins

The water is evaporated - and what remains is protein protein powder. That is, it is a natural and much more easily digestible product (digested within an hour) than meat that requires long digestion and has toxins in the remainder. Hydrolyzed protein is incomprehensible to many, like isolate. Namely, the manufacturing method, etc. These products for our children should not contain lactose and casein. These proteins are digested practically without the help of enzymes and do not form toxins during the digestion process

Another mom's opinion

Better natural protein (meat) or even hydrolyzate made for children than whey protein. I think it is difficult for the child's body

Serum in cosmetology

The unique properties of the serum are not spared in the cosmetic area, so it is used externally for:

eliminating freckles;
cleaning the epidermis of the face;
strengthening hair shafts;
improving the growth and appearance of eyelashes and eyebrows;
eliminating corns and calluses on the feet.

Application on the face and hair is presented in the following subsections, on eyelashes and legs - in the table:

Region	How to use	Result
Eyelashes, eyebrows	Topical application of serum to the area + drinking the drink orally	Strengthening, growth
Feet	A warm solution of whey and water, prepared in a 1:1 ratio, is placed in a basin and the legs are immersed there.	Removing calluses and corns

You should not expect results from homemade masks, scrubs and other products the very next day - they provide long-term results that are visible after four to eight weeks of regular use. For cosmetic purposes, it is better to use homemade whey from homemade milk.

Whey Protein Production Today

Are you interested in production process in our online store? We'll tell you how it really works.

Cow's milk is transported from farms to cheese producing companies. There, the whey is separated from the cheese and sent to whey processing plants, where it is filtered. The resulting product after filtration is WPC 80 whey protein . After a microfiltration process, it becomes whey isolate . The production of whey hydrolysate also uses hydrolysis process , where digestive enzymes are added to the protein for better and faster absorption.

Whey protein is then dried and stored in large bags as a powder. Flavoring agents are then added for flavor or specific types of whey protein are blended and other active ingredients are added, depending on the multi-component protein composition . The whey protein is then placed in jars and sent to companies that sell nutritional supplements for athletes. The last step in this process is delivering the protein to your home or the gym you visit. [6]
