Embodiment 2

[0057] A process for processing Peruvian squid whiskers, comprising the following steps:

[0058] (1) Pretreatment: thaw the frozen squid, wash and drain, and set aside.

[0059] (2) Osmosis treatment: Under vacuum conditions, the pretreated squid must be placed in the infiltration solution, soaked at 4°C for 30 minutes, and the ratio of solid to liquid is 1:2. Wherein, the above-mentioned permeate is a compound saline solution in which sodium pyrophosphate, sodium tripolyphosphate, sodium hexametaphosphate and sodium chloride are dissolved, and sodium pyrophosphate, sodium tripolyphosphate, sodium hexametaphosphate and The mass concentration of sodium chloride is respectively: 40%, 35%, 5%, 5%.

[0060] (3) Pre-separation: Place the pretreated squid whiskers on a heating plate, then place an extrusion plate on the squid whiskers, heat at 60°C for 4 seconds, and squeeze the squid whiskers with the squeeze plate during the heating process. It can be seen from Example 1 that t...

Embodiment 3

[0066] A process for processing Peruvian squid whiskers, comprising the following steps:

[0067] (1) Pretreatment: thaw the frozen squid, wash and drain, and set aside.

[0068] (2) Osmosis treatment: Under vacuum conditions, the pretreated squid must be placed in the infiltration solution, soaked at 7°C for 45 minutes, and the ratio of solid to liquid is 1:3. Wherein, the above-mentioned permeate is a compound saline solution in which sodium pyrophosphate, sodium tripolyphosphate, sodium hexametaphosphate and sodium chloride are dissolved, and sodium pyrophosphate, sodium tripolyphosphate, sodium hexametaphosphate and The mass concentration of sodium chloride is respectively: 42%, 37%, 7%, 7%.

[0069] (3) Pre-separation: place the pretreated squid whiskers on a heating plate, then place an extrusion plate on the squid whiskers, heat at 80°C for 3 seconds, and squeeze the squid whiskers with the squeeze plate during the heating process. It can be seen from Example 1 that t...

Abstract

The invention relates to a processing technology of Peruvian squid whiskers. The method includes the following steps of pretreatment, osmosis treatment, pre-separation, rapid cooling, rolling tooth removal and enzymolysis and sucking-disc separation. Compared with a traditional method, the tooth removal rate is greatly improved (the tooth removal rate is higher than 96%), a physical means is usedfor tooth removal, the tooth removal cost is low, the process is environmentally friendly and free from pollution, the conditions of the Peruvian squid whiskers after tooth removal is good, and the quality of the Peruvian squid whisker products after tooth removal can be effectively ensured. Moreover, after tooth removal, biological enzymes are used for sucking-disc separation, the sucking-disc separation rate can reach 100%, residual ring teeth in the sucking disc can be effectively avoided, the separated sucking disc can be utilized, and thus a theoretical basis is provided for further development of squid production.

Description

technical field [0001] The invention relates to the field of seafood processing, in particular to a process for processing Peruvian squid silk. Background technique [0002] Squid, also known as squid and calamari, is an animal of molluscs, cephalopods, sheaths, tenbrachiarches, squids, and squids. It has a conical body, pale body color, light brown spots, a large head, and frontal growth There are 10 tentacles, and the fins at the end of the tail are triangular. They often swim in groups in the ocean at a depth of about 20 meters. Squid are mainly distributed in tropical and temperate shallow seas. Among them, the Peruvian squid (Dosidicus gigas), commonly known as the American red squid, is one of the largest and most abundant predatory squid species discovered so far. Squid sucker is a by-product of the processing of Peruvian fish whiskers. Due to the lack of effective utilization methods, it can only be sold at a low price as a raw material for fish meal. Difficulty, r...
