Method for slaughtering of live soft-shelled turtle and low-temperature liquid-state quick-freezing fresh-keeping of slaughtered soft-shelled turtle

Abstract

The invention relates to an aquatic product fresh-keeping method and especially relates to a method for slaughtering of a live soft-shelled turtle and low-temperature liquid-state quick-freezing fresh-keeping of the slaughtered soft-shelled turtle. The method mainly solves the technical problem that the prior art can cause soft-shelled turtle cell membrane frost cracking in quick-freezing fresh-keeping so that the food acidizes and goes bad and thus after unfreezing, fresh aquatic food quality and taste are not kept and a unique local flavor of soft-shelled turtle is poor. The method comprises the following steps of slaughtering soft-shelled turtle by incising the neck of the soft-shelled turtle, collecting blood from the neck, carrying out immersion, carrying out membrane removal, carrying out cleaning, splitting the back, taking out internal organs, carrying out dehydration, carrying out immersion in special honey for antioxidation fishy smell-elimination treatment, carrying out honey removal, carrying out vacuum packaging, carrying out metal detection, carrying out immersion in a low-temperature liquid for quick-freezing, carrying out quick-freezing in a refrigeration storage for quick-freezing killing of parasites, carrying out packaging by a thermal insulation package box, putting the thermal insulation package box into a cold storage bag, sealing four sides of the cold storage bag, packaging the cold storage bag by a carton box, and transferring the carton box into a refrigeration storage for finished product storage.

Description

technical field [0001] The invention relates to a method for preserving freshness of aquatic products, in particular to a method for preserving live soft-shelled turtles by low-temperature liquid quick-freezing. Background technique [0002] my country is one of the countries with the largest production of aquatic products in the world, and it is also the only country in the world where the amount of aquaculture exceeds the amount of fishing. And with the introduction and breeding of high-quality freshwater soft-shelled turtles, the output of soft-shelled turtles is constantly expanding. The soft-shelled turtle has rich nutritional value, less connective tissue, and soft meat with high nutritional value. Chinese patent discloses a fresh-keeping method of live soft-shelled turtles in low-temperature liquid state (publication number: CN 103168825 A), which includes the following steps: firstly, the aquatic products are washed with cold water to remove dirt and impurities, and...

Problems solved by technology

[0003] The present invention provides a low-temperature liquid quick-freezing fresh-keeping method for soft-shelled soft-shelled turtles, which mainly solves the problems in the prior art that soft-shelled soft-shelled turtles will freeze and crack the cell membranes of soft-shelled turtles during refrigeration and preservation, and the food will be acidified and deteriorated, and cannot be kept alive and fresh after thawing. Technical problems such as poor quality, taste and unique flavor of soft-shelled turtle
