Embodiment 1

[0029] Example 1: Research on sucker ring teeth of Peruvian squid

[0030] Raw materials: Frozen Peruvian squid silk, purchased from Zhoushan Haili Oceanic Fishery Co., Ltd.

[0031] Reagents: standard bovine serum albumin, Sigma Company of the United States; chitin, Shanghai Sangong Bioengineering Co., Ltd.; other hydrochloric acid and sodium hydroxide reagents were of analytical grade, Sinopharm Chemical Reagent Co., Ltd.

[0032] Instruments and equipment: Nicolet 6700 infrared spectrometer, Thermo Nicolet Company of the United States; HH-4 electric heating constant temperature water bath, Changzhou Guohua Electric Co., Ltd.; LGJ-10 freeze dryer, Beijing Songyuan Huaxing Technology Development Co., Ltd.; GZX-9240MBE electric heating Blast drying oven, Shanghai Boxun Industrial Co., Ltd.; Phenom desktop scanning microscope, Funa Scientific Instruments Shanghai Co., Ltd.; DFT-250 high-speed universal pulverizer, Shanghai Chuding Analytical Instrument Co., Ltd.; 200F 3 differe...

Embodiment 2

[0055] A method for breaking away from squid sucker ring teeth, comprising the following steps:

[0056] (1) Pretreatment: thaw the frozen squid, wash and drain, and set aside.

[0057] (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%.

[0058] (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...

Embodiment 3

[0062] A method for breaking away from squid sucker ring teeth, comprising the following steps:

[0063] (1) Pretreatment: thaw the frozen squid, wash and drain, and set aside.

[0064] (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%.

[0065] (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...

Abstract

The invention relates to a method for breaking away from squid sucker ring teeth, which comprises the following steps: (1) pretreatment: thawing frozen squid whiskers, cleaning and draining, and standby; (2) osmosis 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 extruding plate at the same time; (4) rapid cooling: put the pre-separated squid whiskers into the fluidized ice solution to cool; (5) rolling detooth: take the cooled squid whiskers out of the water , Roll the squid tendrils to separate the ring teeth from the squid tendrils. Compared with the traditional manual degearing method, the present invention greatly improves the degearing rate (the degearing rate can be as high as about 95%), and completely adopts physical degearing, which has low cost of degearing, environmental protection and no pollution, and can effectively guarantee Quality of squid silk products after tooth removal.

Description

technical field [0001] The invention relates to the field of seafood processing, in particular to a method for detaching 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. Difficulty,...
