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 ring teeth of a Peruvian squid sucker. The method includes the following steps that 1, pretreatment is performed, wherein frozen squid whiskers are thawed, cleaned and drained for standby application; 2, pre-separation is performed, wherein the pretreated squid whiskers are placed on a heating plate, then an extrusion plate is placed on the squid whiskers, heating is conducted for 2-4 s at 60-80 DEG C, and simultaneously the extrusion plate extrudes the squid whiskers in the heating process; 3, rapid cooling is performed, wherein the pre-separated squid whiskers are put in a fluidized ice solution for cooling; 4, rolling and teeth detaching are performed, wherein the cooled squid whiskers are taken out from water for roll extrusion, so that the ring teeth are separated from the squid whiskers. Compared with a traditional manual tooth detaching mode, the tooth detaching rate is greatly improved (the tooth detaching rate can be up to about95%), the teeth are detached only by a physical way, the tooth detaching cost is low, the method is environmentally friendly and free from pollution, and the quality of squid whisker products can be effectively ensured after tooth detaching.

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....
