Accurate said 100 ℃ drying after 3 h after the sample is about 0.15 g, according to the conventional determination of kjeldahl determination.
0.1 molar of sulphuric acid per milliliter is equivalent to 1.401 mg of nitrogen.
Toxicity LD50400 ~ 500mg/kg (casein sodium, rats, mouth).
Natural food, not toxic.
Chemical white to pale yellow particles, powder or flake.
Odorless, odorless, or slight aroma and taste.
Not soluble in water and alcohol.
The lye is a casein acid salt.
The isoelectric point is a pH of 4.6.
If the washing is not sufficient in the manufacturing process and the remaining sugar (lactose) is not sufficient, the maillard reaction can cause brown change when the drying is heated.
Use thickener;
Emulsifier;
Stabilizing agent;
Nutrient fortifier (reinforcing protein);
Binder;

Carrier.
It is especially suitable for cheese and ice cream, serving between 0.3% and 0.7%, meat products (ham, sausage) 1% ~ 3% and aquatic meat products.
Fortified bread and biscuits with 5% protein;
3% of mayonnaise.
Use acid casein is used mainly as the substrate of coating, glue of wood, paper and cloth, food additives etc.
As the base material of coating is about half of total consumption, have excellent water resistance, in the pigment can be dispersed very well, improve the uniformity of coating.
In addition, because of the good liquidity, easy to apply for construction, the crude clotting enzyme 2 protein is mainly used to make plastic button.
The casein button is better than any other resin button, the dyeing, the processing, the color and the color are all good, the quality is in the center of the button.
Casein mixing with lime hydrate, sodium fluoride, copper sulfate, match again get casein glue into the kerosene, aviation industry is the use of a cement and wood processing department.
Casein is also used in medicine and biochemical reagents.
