Embodiment 2

[0057] A processing technology for squid sucker ring teeth, 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 tha...

Embodiment 3

[0064] A processing technology for squid sucker ring teeth, comprising the following steps:

[0065] (1) Pretreatment: thaw the frozen squid, wash and drain, and set aside.

[0066] (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%.

Abstract

The invention relates to a treatment process for squid sucker ring teeth, which comprises the following steps: (1) pretreatment: thawing frozen squid whiskers, cleaning and draining, and standby; (2) infiltration treatment: under vacuum conditions, the pretreated Put the squid whiskers into the permeate; (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-80°C for 2-4s, the heating process Squeeze squid whiskers with extrusion plate at the same time; (4) rapid cooling: put the squid whiskers after pre-separation into fluidized ice solution to cool; (5) enzymatic detoxification: adopt flavor enzyme and collagenase to cool The squid whiskers are enzymatically hydrolyzed to separate the ring teeth from the squid whiskers. The invention greatly improves the tooth removal rate (the tooth removal rate is higher than 96%), and adopts the combination of physical means and biological means for tooth removal, which has low cost of tooth removal, environmental protection and no pollution, and the appearance of squid whiskers after tooth removal is good. The added value of the product is high, which can effectively guarantee the quality of squid whiskers after tooth removal.

Description

technical field [0001] The invention relates to the field of seafood processing, in particular to a processing technology for squid sucker ring teeth. 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. Diffic...
