Speaking of food additives, we all know that food additives are used to improve the color, aroma and taste of food, adjust the nutritional composition of food and prolong the shelf life of food. But when it comes to the use of sodium hexametaphosphate in food processing, many people may not know. Today, Chongqing Chuandong Chemical will tell you about the source, classification and use of the food additive sodium hexametaphosphate.

First of all, sodium hexametaphosphate is divided into industrial and food grade. The source of sodium hexametaphosphate is produced by phosphoric acid processing technology. Here is an important information that food grade sodium hexametaphosphate must be produced by thermal phosphoric acid in order to achieve the corresponding impurities, heavy metals and other control indicators.

Sodium hexametaphosphate is widely used in food industry. Let's show you a few of them which can be used in daily life.

1. Sodium hexametaphosphate can be used in meat products, fish sausage, ham, etc. It can improve water holding capacity, increase knotability and prevent fat oxidation.

2. Used in soybean paste and soy sauce can prevent discoloration, increase viscidity, shorten fermentation period and adjust taste.

3. Used in fruit drinks and cool drinks, it can increase juice yield, increase viscosity and inhibit the decomposition of vitamin C.

4. Ice cream can increase expansion capacity, volume, emulsification, prevent paste damage, improve taste and color.

5, for dairy products, beverages to prevent gel precipitation;

6. Adding beer can clarify liquor, prevent turbidity and improve beer taste.

7. For canned beans, fruits and vegetables, it can stabilize natural pigments and protect food color.

8. Sodium hexametaphosphate aqueous solution sprayed on cured meat can improve the anti-corrosion performance.

9. Biscuit loosening agent. It can reduce dough gluten, improve biscuit porosity, and reduce the amount of sugar and fat.

Sodium hexametaphosphate, as an innovative additive in food industry, has greatly promoted the development of food industry, satisfied various operations of food processing, adapted to automatic mechanical production, and coexisted the delicacy and storage of food.
