Technological recommendations

Potassium citrate is widely used in various fields of the food industry.

One of the main directions of its application is the processing of milk, to which it is added as a stabilizer salt to maintain the ionic equilibrium necessary for the thermal stability of the product being heated. In practice, potassium citrate is added as a 10-25% solution. Its concentration depends on the thermal stability of a particular batch of milk, therefore it varies widely from 0.05 to 0.4% of the mass of the normalized mixture. Potassium citrate according to GOST 5538-78 "Potassium citric acid single-water. Technical conditions" included in the list of raw materials in GOST 1923-78 "Canned milk, condensed milk sterilized in cans. Technical conditions".

When using potassium citrate as a melting salt in the production of processed cheeses, its bookmark rate is up to 40 g per 1 kg of the final product.

When stabilizing chopped meat products, the concentration of potassium citrate should be up to 3 g/ kg of meat or fat, or up to 16 g/ kg of blood of slaughtered animals.

Potassium citrate is also used as a regulator of acidity and consistency in jams, jams, jelly on pectin, desserts, bakery products in an amount of about 10 g / kg. To enhance the action of antioxidants in juices, margarine, vegetable oil, pork fat, it is laid in a concentration of 100 mg / kg.
