Comparison of protein powder purity

1. Steps for determining the elasticity of protein powder

Take an appropriate amount of protein powder, dissolve and stir in a water to protein powder ratio of 1:7.5. Cut a suitable length of casing, pour the dissolved protein powder into it, adjust the constant temperature water bath to 95 degrees, put it into the intestine, boil for about 30 minutes, then remove it, cool with cold water, and refrigerate it in a refrigerator at around 4 degrees for 8 to 10 hours.
Take the protein intestine after refrigeration, cut it into small pieces of about 10cm, place it on the operating table, set the correction (usually set to (30,1.0)), and start measuring. Generally, each segment of the intestine is measured at around 6 points. After the measurement is completed, the maximum and minimum values are removed, and the average of the remaining values is taken as the elasticity of the protein powder.

2. The difference between pure powder and impure powder

(1) Elasticity
Pure powder generally has higher elasticity than impure powder. Based on the elasticity measurement data of our company's pure powder and foreign samples over a long period of time, it is reflected that the elasticity of pure powder is generally above 1400, while the elasticity of impure powder after being left for a long time is generally around 1000, which is very small beyond the range.
(2) Solution state
After pure powder dissolution, the solution becomes clear and transparent, similar to or even clearer than egg white. After the impure powder dissolves, some layers, some solutions turn yellow, and some even turn slightly red. The cooked pure sausage is in bright state, while the impure powder has different colors, and some can see obvious stratification through the intestines.
(3) Taste
The taste of pure powder and impure powder is different. After dissolving an appropriate amount of egg powder, the taste of the pure powder solution is normal egg white liquid flavor, while impure powder may have a bean powder flavor, some may have some other fishy smell, and so on. Of course, the taste of the solution depends on the substances and amount added to the egg powder. This cannot be used as a criterion for judgment.
(4) Water retention
When measuring the cooked protein sausage body, impure sausage will experience water seepage in the measuring hole, while pure powder will not. Sometimes the pure sausage is thicker than the impure sausage when cooked under the same conditions.
(5) Change in state after placement
Under the same conditions, pure protein powder can be left for a longer time with little change in state, which is mainly reflected in:
1. After being placed for a period of time, only the outer layer of the pure protein sausage body becomes slightly hard, while the outer layer of the impure sausage body changes slightly as the hardness of the pure powder, and the hardness of the impure part changes more. It can also be seen that the water retention of impure powder is worse than that of pure powder.

2. The volume of pure sausage basically remains unchanged, while the volume of impure powder will be significantly reduced.

How to choose protein powder correctly

1. Check the source of raw materials

Whey protein is preferred because it has higher essential amino acid content, biological value, protein efficiency, and other evaluation indicators than casein and soy protein. Secondly, choosing soy with whey protein has the advantage of being cheaper than pure whey protein powder. Finally, choose soy protein. Its main ingredient is soybeans, suitable for people with milk allergies but who 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 they do not have high-quality protein.

2. Look at the ingredient list

Check the ingredient list to confirm the protein source. Generally speaking, the content at the top of the ingredient list is the highest; The fewer ingredients, the better. According to digestion and absorption rate, whey protein>casein>soy protein>pea and wheat protein. Whey protein is more suitable for patients with malnutrition and tumors. In addition, patients with severe lactose intolerance should choose those without lactose.

3. Look at the nutritional ingredient list

Confirm the protein content, the higher the protein content, the better. The protein content of high-quality protein powder will be above 70-80%.
