Problems solved by technology

However, excessive use of phosphate is harmful to the flavor of aquatic products, and at high concentrations (0.4%-0.5%), phosphate will produce an unpleasant metallic astringent taste. Excessive use will lead to deterioration of product flavor and rough tissue structure, but the amount When it is insufficient, it cannot play a good water retention effect

Embodiment 4

[0034] A water retention method for large yellow croaker, specifically comprising the following steps:

[0035] Step 1, the fresh large yellow croaker is descaled, gutted, peeled, cleaned, then drained and weighed to obtain large yellow croaker flesh (pretreated large yellow croaker);

[0036] Step 2. Place 3 kg of the large yellow croaker meat obtained in step 1 in the non-phosphorus water-retaining agent for large yellow croaker of Examples 1-3 and Comparative Examples 1-4 respectively, and soak in an environment of 4°C for 7 hours;

[0037] Step 3. Vacuum-pack the large yellow croaker flesh soaked in step 2 and store it in an environment of -80°C for 5 weeks to obtain 8 frozen samples A-H of large yellow croaker.

Embodiment 5

[0039] A water retention method for large yellow croaker, comprising the following steps:

[0040] Step 1. Descale, viscera, skin and clean the fresh large yellow croaker, then drain and weigh to obtain the large yellow croaker flesh;

[0041] Step 2. Place 3 kg of the large yellow croaker meat obtained in step 1 in the phosphorus-free water-retaining agent for large yellow croaker in Example 1, and soak in an environment at 4°C for 7 hours;

[0042] Step 3, fish out the soaked large yellow croaker meat, place in the coating solution and soak for 2 minutes, the coating solution is 0.5% chitosan solution configured with 1% acetic acid;

[0043] Step 4: Vacuum-pack the large yellow croaker flesh after the coating treatment in step 3 and store it in an environment at -80°C for 5 weeks to obtain a frozen sample I of large yellow croaker.

Embodiment 6

[0045] The difference between Example 6 and Example 5 lies in that the soaking temperature in the step 2 is 0°C and the soaking time is 4h, and the storage temperature in the step 4 is -18°C, and the frozen sample J of large yellow croaker is obtained.

Abstract

The invention discloses a phosphorus-free water-retaining agent for larimichthys crocea and a water-retaining method thereof, and belongs to the technical field of aquatic product processing; the phosphorus-free water-retaining agent comprises the components in parts by weight: 20-25 parts of sodium citrate, 10-15 parts of sodium bicarbonate and 45-60 parts of tamarind polysaccharide gum, and themass ratio of the sum of sodium citrate and sodium bicarbonate to tamarind polysaccharide gum is 1: 1.5. The water-retaining agent for larimichthys crocea provided by the invention can effectively enhance the water-retaining capacity of larimichthys crocea, avoids the loss of a large amount of water after long-term cryopreservation and thawing, improves the quality and processing characteristics of larimichthys crocea, and avoids the potential risk caused by phosphate as the raw materials do not contain phosphate; According to the water retention method, the phosphorus-free water-retaining agent is used for soaking the larimichthys crocea meat, the treatment method is simple, the required manpower and material resource cost is low, and popularization and large-scale production of enterprises are facilitated.

Description

technical field [0001] The invention belongs to the technical field of aquatic product processing, and in particular relates to a phosphorus-free water-retaining agent for large yellow croaker and a water-retaining method thereof. Background technique [0002] The large yellow croaker is mainly distributed in the South my country Sea, the East China Sea and the southern part of the Yellow Sea. It is an important coastal economic fish in my country. The flesh of large yellow croaker is rich in amino acids, minerals, vitamins and trace element selenium. The human body has a high absorption rate and is suitable for different groups of people. [0003] my country is a country with a large population, and the consumption of aquatic products is huge. The output of my country's aquatic products is mainly concentrated in coastal areas. The realization of long-distance and large-scale supply across the country depends on modern advanced processing and storage technologies and develop...
