Embodiment 1

[0025] Example 1: Research on sucker ring teeth of Peruvian squid

[0026] Raw materials: Frozen Peruvian squid silk, purchased from Zhoushan Haili Oceanic Fishery Co., Ltd.

[0027] 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.

[0028] 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

[0051] A method for detaching the sucker ring teeth of Peruvian squid, comprising the following steps:

[0052] (1) Pretreatment: thaw the frozen squid, wash and drain, and set aside.

[0053] (2) 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 the main component of ring teeth is protein, and protein has the problem of heat denaturation, so in this example, the heating temperature is set at 60°C and the heating time is set at 4s. After the ring tooth is heated, it softens and has a certain adhesion with the extrusion plate, so that the extrusion plate can have a certain stretching effect between the ring tooth and the suction cup while extruding the ring tooth, so as to realize the suction cup and the sucker. Separation of ring teeth.

Embodiment 3

[0057] A method for detaching the sucker ring teeth of Peruvian squid, comprising the following steps:

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

[0059] (2) 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 the main component of ring teeth is protein, and protein has the problem of heat denaturation, so in this example, the heating temperature is set at 80°C and the heating time is set at 2s. After the ring tooth is heated, it softens and has a certain adhesion with the extrusion plate, so that the extrusion plate can have a certain stretching effect between the ring tooth and the suction cup while extruding the ring tooth, so as to realize the suction cup and the sucker. Separation of ring teeth.

Abstract

The invention relates to a method for detaching the sucker ring teeth of Peruvian squid. Place it on a heating plate, then place an extruding plate on the squid whiskers, heat at 60°C-80°C for 2-4 seconds, and squeeze the squid whiskers with the extruding plate at the same time during the heating process; (3) Rapid cooling: after pre-separated The squid must be put into the fluidized ice solution to cool; (4) rolling and detoothing: the cooled squid must be taken out from the water, and the squid must be rolled to separate the ring teeth from the squid. 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 detachment method for sucker ring teeth of Peruvian squid. 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....
