Aquatic products need water retention, which is a little different from other products. Sometimes when water is retained, it will be consumed greatly after cooked processing or thawing. As we all know, once the water loss of aquatic products has a great impact on the taste, the product has slag, has no original taste, and the color is very bad. When food additive sodium tripolyphosphate is used in aquatic products processing, can it still keep water and improve meat quality without color loss?

Sodium tripolyphosphate is mainly used in aquatic products processing to keep water in food during food processing, which can improve the color, flavor, morphology, anti-oxidation and water retention of food. For the production and processing of shrimp, sodium tripolyphosphate is used in the soaking process. It is soaked in aqueous solution for more than 1 hour, and the standard is 1PPM. The finished product will not exceed the standard.

The advantages of sodium tripolyphosphate for aquatic products processing are:

1. Fast dissolution and strong permeability.

2. Keep water and increase weight, reduce the loss of nutrients in the processing process, and improve the product yield.

3. Dissociate actin, prevent meat oxidation, increase the ionic strength of meat, keep fresh and protect color, significantly improve the quality, shape and flavor of food, and protect the fresh and tender taste of products.

4. Inhibit the growth of microorganisms, improve the stability and water holding capacity of products, and prolong the fresh-keeping and storage period of products.

With the development of economy and the improvement of residents' material living standards, consumers' demand for aquatic products has changed from single output to quality and output. Ice wet refrigeration, micro freezing refrigeration, rapid freezing preservation and cold sea water preservation technology will be gradually and widely used in aquatic products industry. Therefore, the food additive sodium tripolyphosphate as water retaining agent is also widely used in aquatic products processing enterprises, and gradually began to carry out intensive processing, promoting the optimization and upgrading of the industrial structure of aquatic products.
