How Can You Check the Protein Quality at Home by Yourself?
On the modern sports nutrition market, there are a large number of protein supplements for every taste and budget. But in order not to be mistaken in the choice and purchase a really high-quality product, many ask the question: how to check the protein for quality? Get to the answer in this article created by our team.
The most effective and 100% method that will surely help determine which protein is in your jar is a laboratory test. But carrying your powder to the laboratory is a rather costly measure and is more suitable for the very curious, so here are some practical tips on how everyone can check the protein at home.
Learn the composition
The very first and most important thing to pay attention to is the composition of the package. An unscrupulous manufacturer will often fill a product with the cheapest type of protein, for example, soy protein in a multicomponent protein, as well as an unbalanced amino acid profile.
The most common is an increase in the amount of taurine, glycine, and beta-alanine – cheaper components per gram.
For the person, it may seem that a large amount of taurine, glycine, and beta-alanine is not so critical, but in fact, the manufacturer preferred to save money by selling you a lower quality product.
Therefore, when choosing a protein, always pay attention to the following.
The amino acid composition is not specified – this indicates that cheaper ingredients may prevail in the composition.
The amount of leucine is less than 2.5-2.7 grams per serving – a quality protein should be 11% leucine and 25% branched-chain amino acids (BCAA).
A disproportionate ratio of cheaper amino acids (glycine, taurine, and beta-alanine) to leucine, isoleucine, and valine.
Check it yourself
Having studied the packaging, you can go to its content, by what external signs can you determine the quality of the protein?
It should be noted right away that experiments with iodine, boiling, and igniting protein is not effective. Protein, in addition to the protein itself, can contain carbohydrates, flavour enhancers, and flavours – all this can affect whether the product will curl, colour, or acquire a characteristic odour.
How can you check the quality of a product?
Snow crunch. The most popular way is to crunch. Regardless of whether the protein has the consistency of a powder, or it slightly clumps, a quality product emits a characteristic crunch when compressed (vaguely reminiscent of the crunch of snow or sand).
Protein decay. Any product can deteriorate, but protein is characterized by decomposition and decay processes, which are accompanied by a characteristic odour. Therefore, if you put a protein shake (or even its remnants) in the sun or next to a battery, then it will begin to decompose, exuding a putrid smell. In the case of low-quality protein, the product will simply swell.
Here are, perhaps, the simplest, most basic ways to test protein quality without having any special equipment or a whole laboratory at hand. However, if you want to be sure that you are buying a high-quality product visit the My Protein website, all products are certified, quality is guaranteed.
