A kind of fresh-keeping method of red shrimp

Abstract

The invention discloses a preservation method of red shrimps. The preservation method comprises the following steps: (1) preparing modified nano SiO2; (2) preparing a preservative; (3) performing cleaning; (4) performing precooling; (5) performing soaking so as to obtain membranes; and (6) performing refrigeration. According to the preservation method of the red shrimps, through the cooperation of the steps of precooling and soaking the red shrimps in the preservative so as to obtain the membranes, at the low temperature, the red shrimps are prevented from fading, blackening and decaying, and carapace can be prevented from dropping off; the preservation method is simple in technological process, is high in efficiency, is safe and low in cost, and the preservation time can be prolonged under the premise that the exterior quality of the red shrimps are guaranteed. The invention further provides a preservative formula and a preparation method, which are designed according to the biochemical characteristics of the red shrimps, the preparation steps are simple, the equipment investment is less, and the cost is low, so that the preservative formula and the preparation method are suitable for large-scale industrialized production; the ingredients in the preservative have synergetic effects, the preservative has the effects of bacteriostasis, preservation, color protection and blackening prevention, can prevent the red shrimps from fading, blackening and decaying, and can prevent the carapace from dropping off, the preservation time of the red shrimps can be prolonged, and the red shrimps are good in quality, so that the preservative has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping aquatic products, in particular to a fresh-keeping method for red shrimp. Background technique [0002] Red shrimp, named Solenocera Melantho in Latin, is widely distributed in the East my country Sea, the southern Yellow Sea and the South China Sea. It is a dominant species in Zhejiang's offshore resources, especially in the central and northern parts of Zhejiang. Because it has a natural pink shrimp shell, the meat is tender and smooth, delicious, and rich in protein and various nutrients. It has high therapeutic value and can enhance the immunity of the human body. All have been highly praised by consumers. [0003] The carapace of red shrimp is relatively large, and the muscle tissue is easy to soften during transportation or storage after death, which will easily cause the carapace of red shrimp to fall off, affecting the appearance quality, and is also very susceptible to bacterial at...
