Sodium tripolyphosphate is one of the commonly used water retaining agents in meat processing. It has a strong adhesive effect, can also prevent discoloration, deterioration and dispersion of meat products, and has a strong emulsification of fat. The meat products added with sodium tripolyphosphate have less water loss after heating. The finished products are complete, with good color, tender meat, easy to slice, and glossy cut surface. It is a kind of phosphate widely used.

Sodium tripolyphosphate water retaining agent is generally used in western sausage, ham, meatballs and other products. Most of the products in this series have one characteristic, the product style is very standard, and the type and quantity of raw meat can not be seen from the surface.

In use, it is safe to add limited amounts in strict accordance with the requirements of GB2760.

As a traditional water retaining agent, food grade sodium tripolyphosphate has played an important role in the meat product processing field for many years. Food grade sodium tripolyphosphate is favored by meat product processing enterprises because of its low cost and wide application range.
