Food Safety-milk and Protein

Protein is the main nutrients in milk. The National Standard for Fresh milk is 100 ml or greater than 2.95 grams, while the protein content of pure fresh milk is generally more than 3%, generally can meet the national standard.

In the food industry, the protein content in milk is determined as the national standard. The principle is very simple: protein contains nitrogen elements, processing samples with strong acid, releasing nitrogen elements in the protein, determination of nitrogen content, you can calculate the protein content.

The nitrogen content of milk protein is about 16%. according to national standards, the nitrogen content measured is multiplied by 6.38, which is the protein content. Under normal circumstances, only protein is contained in milk Containing Nitrogen elements, but some merchants will pay for water in milk to make more money. At this time, the amount of nitrogen in milk that has been mixed with water naturally decreases, as a result, the unscrupulous merchants will add other nitrogen-containing substances to the milk, and then they will be able to cheat the kaishi nitrogen determination method to obtain a false high protein content.

Melamine contains up to 66.6% nitrogen and is white and tasteless. It is an ideal protein impersonate without a simple method. It is estimated that the testing protein content will be increased by one percentage point in plant protein powder and feed, with melamine spending only 1/5 of the actual protein raw material.
