Abstract

The invention discloses a sulphur-free composite antistaling agent for inhibiting blackening of Penaeus vannamei boone and its preparation method, which aims at solving the current problem that the blackening symptom of Penaeus vannamei boone treated by sodium pyrosulfite enables excessive standard of poisonous and harmful residue which threats the health of human body. The sulphur-free compositeantistaling agent is prepared through mixing the following components by taking water as a solvent: 0.005-0.045mg / mL of 4-hexyl resorcin, 1.00-9.00mg / mL of citric acid, 0.6-2.20mg / mL of EDTA disodiumand 0.10-0.20mg / mL of sodium dihydrogen phosphate. The sulphur-free composite antistaling agent has the advantages of safety, high efficiency and low production cost.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of aquatic products, in particular to a sulfur-free composite preservative for inhibiting blackening of Penaeus vannamei and a preparation method thereof. Background technique [0002] Seawater shrimp and crab occupy a pillar position in my country's aquatic food. Because it contains rich nutrients, the taste produced by the unique taste substances is very consistent with people's best taste, and the taste is delicious, so it is deeply loved by people. There is a high demand for shrimp in the world market, especially in some developed countries. Competition in international trade is fierce, with an annual trade volume of more than 500,000 tons and a trade volume of about US$3.5 billion. However, shrimp itself has a large water content and generally dies soon after being caught. Under the action of microorganisms and enzymes in the body, especially polyphenol oxidase (PPO), it will cause a ...
