Abstract

The invention relates to a method for degrading histamine in aquatic products. The washed aquatic products are immersed in a treating fluid, fished out, drained, put into an insulating bag for high-voltage pulsed electric field treatment, added to a fermentation container and fermented at the controlled temperature of 23 DEG C for 20-35 days; the aquatic products are collected, packaged and put into freezing storage. Histamine produced in the transportation and storage processes of the aquatic products can be remarkably reduced while the specific texture and nutritional ingredients of the aquatic products are retained, growth and metabolism of bacterium colonies producing amino acid decarboxylase activity in the processing process of the aquatic products can be inhibited or prevented better, generation of amino acid decarboxylase is prevented fundamentally, accordingly, generation of histamine is prevented in the whole processing process and is further controlled, and the method has great social and economic benefits.

Description

technical field [0001] The invention relates to a method for degrading histamine in aquatic products with strong operability, simple process and high efficiency. Background technique [0002] Histamine, as a biogenic amine, is produced by the degradation of free histidine under the action of microbial histidine decarboxylase. It widely exists in various organisms and foods, mainly aquatic products, especially scombroids. Histamine is one of the important mediators of inflammatory response and immune injury, and plays an important role in regulating the response to inflammatory response. However, when the human body takes in excessive amounts of histamine, it can cause allergic reactions such as headaches, nausea, palpitations, changes in blood pressure, breathing disorders, and even life-threatening. When the body ingests 8-40 mg of histamine, it will produce mild poisoning symptoms, when it exceeds 40 mg, it will produce moderate poisoning symptoms, and when it exceeds 100...
