Water-retaining agent for frozen shrimp meat, and preparation method and application thereof

Abstract

The present invention discloses a water-retaining agent for frozen shrimp meat. The water-retaining agent comprises the following components by weight: 2-4% of alginate oligosaccharide, 1-3% of sucrose ester, 0.3-0.5% of sodium carbonate, 0.5-1% of sorbitol, 0.5-1% of sodium caseinate, 0.3-0.5% of xanthan gum and the balance of water. The water-retaining agent for frozen shrimp meat uses readily available and low-cost ingredients, which are environment-friendly and safe and mutually cooperate. The water-retaining agent has excellent water retention properties, and can better maintain the fresh flavor and flexibility of shrimp, so as to reduce loss of shrimp juice and guarantee the quality of frozen shrimp meat. The present invention also discloses a preparation method of the frozen shrimp meat; the method has simple steps, less investment in equipment, and strong operability, and is applicable to industrial production.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to a frozen shrimp water-retaining agent and its preparation method and application. Background technique [0002] As the storage time increases, the water-holding quality of frozen shrimp decreases. When thawing and heating, the juice loss increases, resulting in quality loss, meat hardening, brittleness, rough taste, and dark appearance. Therefore, it is very important to improve the water retention of shrimp. [0003] Polyphosphate is widely used as an efficient water retention agent in meat products and seafood products. However, excessive use of polyphosphate will cause unpleasant metallic astringent taste and rough tissue structure in food, and long-term excessive intake will affect the calcium and phosphorus balance of the body. Therefore, it is of great practical significance to develop a safe and efficient water-retaining agent for frozen shrimp. [00...
