Problems solved by technology

There are relatively few domestic studies on enzymatic squid skin removal, the process is relatively immature, the yield is low, the peeling effect is poor, the texture of the squid is greatly damaged, and the peeling time is long, and the squid meat is easy to deteriorate
[0004] In addition, squid are usually treated with phosphate-based water-retaining agents for water retention and weight gain during storage. However, in today’s environment that advocates health and environmental protection, the use of phosphates will not only cause eutrophication of water quality, but also cause excessive body fat loss. Intake of phosphate can cause calcium deficiency, which is not good for health

Embodiment 1

[0045] A squid silk enzymatic peeling process is carried out as follows:

[0046] (1) Squid must be pretreated:

[0047] Thaw the frozen squid whiskers under running water, select and classify squid whiskers with similar thickness and thickness, then clean the squid whiskers and soak them in a carboxymethyl chitosan aqueous solution with a concentration of 1 wt%. The squid must be taken out from the carboxymethyl chitosan aqueous solution, cleaned and drained for later use. The mass ratio of the squid silk to the carboxymethyl chitosan aqueous solution is 1:3.

[0048] (2) Enzymatic peeling:

[0049] Put the spare squid silk obtained in step (1) into the skinning mechanism of the peeling machine for skinning, then completely immerse the squid silk in the trypsin enzymatic hydrolysis solution in the peeling machine for enzymatic peeling, wherein, the enzyme The hydrolysis time is 20min, the quality of squid silk is 400 times of the mass of protease in the enzymolysis solutio...

Embodiment 2

[0053] A squid silk enzymatic peeling process is carried out as follows:

[0054] (1) Squid must be pretreated:

[0055] Thaw the frozen squid whiskers under running water, select and classify squid whiskers with similar thickness and thickness, then clean the squid whiskers and soak them in a carboxymethyl chitosan aqueous solution with a concentration of 2wt%. The squid must be taken out from the carboxymethyl chitosan aqueous solution, cleaned and drained for later use. The mass ratio of the squid silk to the carboxymethyl chitosan aqueous solution is 1:2.

[0056] (2) Enzymatic peeling:

[0057] Put the standby squid silk obtained in step (1) into the skinning mechanism of the peeling machine for skinning, then completely immerse the squid silk in the papain enzymatic hydrolysis solution in the peeling machine to carry out enzymatic peeling, wherein, the enzyme The hydrolysis time is 5min, the quality of the squid palpitation is 150 times of the quality of protease in t...

Embodiment 3

[0061] A squid silk enzymatic peeling process is carried out as follows:

[0062] (1) Squid must be pretreated:

[0063] Thaw the frozen squid whiskers under running water, select and classify squid whiskers with similar thickness and thickness, then clean the squid whiskers and soak them in 0.2wt% carboxymethyl chitosan aqueous solution, after 24 hours The squid must be taken out from the carboxymethyl chitosan aqueous solution, washed and drained for later use. The mass ratio of the squid silk to the carboxymethyl chitosan aqueous solution is 1:4.

[0064] (2) Enzymatic peeling:

[0065] Put the spare squid silk obtained in step (1) into the skinning mechanism of the peeling machine for skinning, then completely immerse the squid silk in the bromelain enzymatic hydrolysis solution in the peeling machine for enzymatic peeling, wherein, the enzyme The hydrolysis time is 40min, the mass of squid palpitations is 2000 times of the mass of protease in the enzymolysis solution, ...

Abstract

The invention relates to the technical field of squid process and discloses a squid tentacle enzymatic dehulling process. The process comprises the following steps: (1) pretreating squid tentacle, namely unfreezing the frozen squid tentacle, washing to obtain the squid tentacle, immersing the squid tentacle in a carboxymethyl chitosan solution, taking out, washing the squid tentacle, and drying for later use; (2) carrying out enzymatic dehulling, hulling the spare squid tentacle, immersing into the enzymatic hydrolysate of a huller to perform enzymolysis hulling; (3) washing and drying, namely washing the squid tentacle, taking out from the huller and drying under room temperature for later use. According to the process provided by the invention, the operation is convenient, the squid tentacle hulling is complete, and the hulling time is short; the squid tentacle hulled through the process is high in yield, good in freshness, and high in white value and slightly influences the squid meat quality.

Description

technical field [0001] The invention relates to the technical field of squid processing, in particular to an enzymatic peeling process of squid silk. Background technique [0002] In recent years, with the rapid development of my country's pelagic squid fishing and the reduction in production of North Pacific squid, Peruvian squid with low value and large catch has become the main target of pelagic squid fishing in my country. In 2013 alone, the catch of Peruvian squid in Zhoushan City was more than 100,000 tons. Peruvian squid is large in size and has a sour taste. It is difficult to sell in the market. It must be processed in order to realize the value-added of resources. At present, domestic squid processing enterprises generally only pay attention to the processing of Peruvian squid carcasses, but ignore the effective use of edible parts such as squid whiskers and ears, and the added value of the product is low. The main reason is that the skin of Peruvian squid is thic...
