Purity comparison of protein powder and how to choose protein powder reasonably?

Protein powder purity comparison
1. Take appropriate amount of protein powder, dissolve and stir according to the ratio of water to protein powder of 1:7.5. Cut off the appropriate length of casings, put the dissolved protein powder into it, adjust the temperature water bath to 95 degrees Celsius, put in the intestines, cook for about 30 minutes, remove, cool with cool water, refrigerate at 4 degrees Celsius for 8 to 10 hours.
Take the refrigerated protein gut, cut it into small segments of about 10cm, place it on the operating table, set the correction (generally set as (30,1.0)), and start to measure. Generally, about 6 points are measured for each segment of intestinal body. After the measurement, the maximum and minimum values are removed, and the average value of the remaining values is the elasticity of the protein powder.
Two, the difference between pure powder and impure powder (a) elasticity
The elasticity of pure powder is generally higher than that of impure powder. Through the elasticity measurement data of our company’s pure powder and foreign samples for a long time, it is reflected that the elasticity of pure powder is generally above 1400, and the elasticity of impure powder is generally about 1000 when placed for a long time, and the scope is very small.
(2) State of solution
After the pure powder is dissolved, the solution is clear and transparent, similar to or even clearer than the egg white liquid. After the impurity powder is dissolved, some are stratified, and some solutions are yellow or even a little red. The cooked pure powder body is in a clear state, and the color of the unclean powder is different, and some can see obvious stratification through the intestinal body.
(3) Taste
The taste of pure powder and impure powder is different, after taking an appropriate amount of egg powder to dissolve, the taste of pure powder solution is normal egg white liquid taste, while the impure powder may be soybean powder taste, and some will have other fishy taste and so on. Of course, the taste of the solution depends on the substance and amount added to the egg powder. This cannot be used as a criterion.
(4) Water retention
When measuring the cooked protein sausage body, the unclean sausage will appear deep water seepage in the measured small hole, while the pure powder will not appear this situation. Sometimes the intestines cooked under the same conditions, the pure intestine will be thicker than the unclean intestine.
(5) State changes after placement
Under the same conditions, the pure protein powder is placed for a longer time, and the state changes little. This change is mainly reflected in: 1. After a period of time, the pure protein powder body only has a slight hardening on the outer surface, while the impure powder body has a greater change in the hardness of the impure part except that the hardness of the outer surface part is the same as that of the pure powder. It can also be seen that the water retention of impure powder is also worse than that of pure powder. 2. The volume of pure powder is basically unchanged, while the volume of unclean powder will be significantly reduced. How to choose the right protein powder
First, look at the raw material source preferred whey protein, because whey protein than casein, soy protein essential amino acid content, raw price, protein efficiency and other indicators of protein evaluation are higher. Secondly, the choice of soy plus whey protein has the advantage that it is cheaper than pure whey protein powder. Finally, soy protein is selected. Its main ingredient is soy, which is suitable for people who are allergic to milk, but need to supplement protein powder. In addition, there are other protein powders such as pea protein powder and peanut protein powder on the market, which are not recommended because there is no high-quality protein.

Second, look at the ingredients list, confirm the source of protein, generally speaking, the top of the ingredients list is the highest content; The fewer ingredients, the better. According to digestion absorption rate whey protein > casein protein > soybean protein > pea, wheat protein. Whey protein is more suitable for patients with malnourished tumors. In addition, patients with severe lactose intolerance should choose lactose free.
Third, look at the nutrition facts table to confirm the protein content, the higher the protein content, the better. The protein content of high-quality protein powder will be more than 70-80%.
