Whey protein is a high-quality protein derived from milk. It plays a vital role in fitness, bodybuilding, and health - increasing muscle density, improving muscle quality, enhancing physical fitness, eliminating exercise fatigue, improving immunity, and improving body shape. ... In short, it is indispensable for building muscle, losing fat, and maintaining health and vitality. However, I am afraid not many people can answer this question correctly: what exactly should whey protein powder look like (referring to characteristics such as appearance, smell, taste, etc.), and what are its different grades and categories? Please see the American Dairy Association's description of the properties of whey protein: It is bland and tasteless, has a unique light fragrance, and looks like a light yellow powder with uniformity and good fluidity. It has emulsifying, foaming, and gelling properties. It can be used as an emulsifier to increase viscosity or turbidity. It can also be used as a foaming agent, but the foam stability is poor. Whey proteins produced by different foreign manufacturers will have some differences in color, powder fineness, solubility, amount and stability of foam during dissolution, viscosity, taste, etc., but the basic state is the same and must be the same. The description above matches.

Whey proteins produced by the same manufacturer are divided according to solubility, including instant type, ordinary type, and some in between, with different prices (of course the instant type is the most expensive); according to protein content, the main ones are There are two types: 34% and 80%, and there are also whey protein isolates as high as 90%, but they are expensive and the output is very small. Whey proteins with different protein contents have similar properties and tastes, but their prices and effects are quite different (the higher the content, the more expensive the price).

Since the effects of whey protein have been widely recognized and more and more users are using it, many whey protein products have suddenly appeared on the market, but a considerable part of them are "selling dog meat with sheep's heads" - using Low-priced protein or substances that look like whey protein are passed off as whey protein to sell at a high price. For example, low-priced proteins such as soy protein and egg protein are used to pass off whey protein, similar-looking substances such as flour, ordinary milk powder, or animal feed whey powder are used to pass off whey protein, and whey protein with a protein content of 34% is also used. Whey protein with a protein content of 80%…. Fake whey proteins generally add a lot of spices, which not only masks the unique taste of the fake raw materials, but also explains why the unique flavor of whey protein cannot be presented, and can also please consumers who simply pursue taste.

In fact, it is very simple to be a smart consumer. As long as you master the following tips, you can greatly reduce the chance of being deceived:

(1) Make a trait calculation based on the description of the above authority.Face comparison;

(2) Choose the correct reference object for comparison. Compare traits

(3) Send it to health and epidemic prevention stations, scientific research institutions, technical supervision bureaus and other units that have the conditions to measure protein content for measurement of nutritional indicators;

(4) Folk method: rinse with boiling water. Soy protein will dissolve quickly after being washed with boiling water. After whey protein is washed with boiling water, many flocculent and granular white objects will appear;

(5) Consult the manufacturer or regular agent of the product to confirm the identity of the place of purchase, or even send the product in question to the original manufacturer for identification;

　(6) Choose a company with a strong brand and strength. It is best to have a factory or a formally registered branch in the country, so that they will be more effectively constrained, and the real subject can be found when handling complaints, claims and other disputes. , such as whey collagen protein powder is produced by Duohe Biotechnology Company, a large domestic GMP enterprise with technical support from Australia Duohe Group. The products have passed various inspections and reached international standards

In short, to distinguish between real and fake whey protein, you must use scientific and objective methods. You cannot judge based on simple appearances such as "good or bad". Some people think that whey protein is bland and tasteless and they are not used to it, but the real whey protein is in this way. When beer first entered China, not many people liked it. At that time, many fruit beers and sweet beers appeared. Now, beer still tastes the same, but it is estimated that few people will doubt or deny the special taste of beer. Fruit beers Beer and sweet beer have also basically disappeared. Therefore, every consumer should think clearly: What is the purpose of buying whey protein at several times the price of ordinary milk powder and delicious milkshakes? Of course, it is most perfect to ensure nutrition and deliciousness, but we must pursue To improve the taste, additives must be used so that whey protein cannot maintain its natural color. The current trend in the world is to pursue naturalness and advocate environmental protection. Whether it is cosmetics, daily care products or food, major brands are launching "additive-free" products one after another. The "Sudan Red" incident that has attracted widespread attention this time has undoubtedly returned. Played a role in fueling the flames. Recently, "additive-free" products have also appeared in the domestic whey protein powder market, and demand exceeds supply as soon as they are launched. This reflects consumers' increasing environmental awareness and trust in natural products.

Main ingredients of whey protein

β-Lactoglobulin

It has the best amino acid ratio and extremely high branched-chain amino acid content, which plays an important role in promoting protein synthesis and reducing protein decomposition, helping fitness enthusiasts to build a beautiful body shape.

α-Lactalbumin

It is an excellent source of essential amino acids and branched-chain amino acids, and is the only whey protein ingredient that can bind metals and calcium. Recent research has found that, which may have anti-cancer properties. In addition, lactalbumin is very similar to human milk in terms of amino acid ratio, structure, and functional properties. Clinical studies show that infant formulas rich in alpha-lactalbumin are safe.

Immunoglobulin

It has immune activity and can completely enter the proximal small intestine to protect the small intestinal mucosa.

Lactoferrin

Antioxidant, eliminate or inhibit bacteria, promote normal cell growth, and improve immunity. ,
