Embodiment 1

[0040] Step 1: Primary processing of raw materials

[0041] Remove the head from the fresh and live shrimp transported from the shrimp pond, clean and disinfect, wash again, and then freeze quickly, each piece is 2 kg, and then pack it into the warehouse to obtain quick-frozen head-off shrimp;

[0042] Step 2: Water retention and freshness processing

[0043] Thaw the quick-frozen headless shrimp obtained in step 1, then remove the shells, and leave the hard shells of the tails after removing the shells, that is, the last section. Open the back and remove the intestinal glands (see the belly line when the shrimp is opened), and then carry out water preservation and freshness treatment. The fresh-keeping treatment is implemented according to the following steps: mix 1 / 3 ice and 2 / 3 cold water according to the volume ratio to make an ice solution, and weigh sodium bicarbonate, citric acid and salt according to the mass percentage of 39%: 41%: 20%. After mixing, dissolve in ice ...

Open the back and remove the intestinal glands (see the belly line when the shrimp is opened), and then carry out water preservation and freshness treatment. The fresh-keeping treatment is implemented according to the following steps: 1 / 3 ice and 2 / 3 cold water are mixed according to the volume ratio to make an ice solution, and sodium bicarbonate, citric acid and table salt are weighed according to the mass percentage of 41%:39%:20%. After mixing, ...

Abstract

The invention discloses a freezing water-holding fresh-keeping processing method for shrimps. The method is implemented concretely according to the following steps: initially processing raw materials; performing water-holding fresh-keeping treatment; wrapping the obtained products in pre-wrapping powder, pulp powder and coconut shred crumbs; putting the obtained products arranged in plates into aquick freezer for quick freezing. Frozen shrimps obtained by the method can be eaten after the frozen shrimps are fried or heated and cooked with microwave so as to ensure rich nutrition and convenience, and can be frozen for transportation so as to maintain the deliciousness and nutrition for shrimp flesh under low-temperature conditions.

Description

technical field [0001] The invention belongs to the technical field of frozen food processing, and in particular relates to a processing method for freezing, water-preserving and fresh-keeping of shrimp. Background technique [0002] Along with the raising of people's living standard and quality, nutritious, delicious, quick, convenient food is subject to people's favor. Overseas hamburgers, pizza, hot dogs, etc. are all meatballs and bread combined, and their deliciousness and nutrition are limited. Shrimp meat is delicious, high in protein, low in fat, rich in nutrition, and is loved by people. Due to technical limitations, at present, when making frozen shrimp food, there are problems that moisture cannot be preserved and the degree of freshness is affected. Contents of the invention [0003] The object of the present invention is to provide a processing method for freezing, water-preserving and fresh-keeping of shrimp, which solves the problems that the existing tech...
