Embodiment 1

[0028] Get 1000 grams of fresh tea leaves, extract tea polyphenols according to a conventional plant polyphenol extraction method to obtain a tea polyphenol extract with a purity of 60%, and prepare a 0.15% formaldehyde scavenger solution with tap water.

[0029] Remove the head, skin and viscera of the squid, clean it and cut it into thin slices with a thickness of less than 1 cm. The thinner the slices, the better the penetration of tea polyphenols.

[0030] According to the ratio of meat to water weight ratio of 1:4, the squid meat is immersed in the formaldehyde scavenger solution, and an appropriate amount of crushed ice is added, so that the water temperature is controlled at 4-10°C during the whole soaking process, and soaked for 10 hours.

[0031] The soaked squid slices are steamed, seasoned and dried to make semi-finished products, stored in cold storage, and then made into shredded squid through steps such as rehydration, roasting, seasoning and drying.

[0032] Und...

Embodiment 2

[0035] The extraction of formaldehyde scavenger, preparation, the pretreatment of squid, section, soaking condition are identical with embodiment 1. The soaked squid is steamed, seasoned, smoked, sliced, seasoned twice, and baked into smoked squid rings.

[0036] Detection of formaldehyde content in squid before and after processing. The formaldehyde content of smoked squid rings soaked with tea polyphenol-containing formaldehyde scavenger before processing is 65% lower than that of unsoaked smoked squid rings.

Embodiment 3

[0038] The formaldehyde scavenger in embodiment 1 is made into 0.1% formaldehyde scavenger solution with tap water.

[0039] Remove the head, skin and viscera of the squid, wash it and cut it into 0.5 cm x 1 cm x 4 cm squid strips.

[0040] According to the ratio of meat to water weight ratio of 1:2, immerse the squid meat in the formaldehyde scavenger solution, and add appropriate amount of crushed ice, so that the water temperature during the whole soaking process is controlled at 4-10°C, and soaked for 14 hours; the soaked squid strips Finished products are cooked.

[0041] Detection of formaldehyde content in squid before and after processing. The formaldehyde content of the squid stick products soaked with the formaldehyde scavenger containing tea polyphenols before processing is 75% lower than that of the unsoaked squid stick products.

Abstract

The invention discloses an effective, safe and economic squid formaldehyde scavenger, the scavenger is the extract from plant material and has the effective component of polyphenolic compound with concentration of 0.05 percent-0.15 percent (w / v). The invention also discloses a method for cleaning endogenous formaldehyde produced during squid processing by the formaldehyde scavenger, the squid is soaked adequately prior to processing, so the formaldehyde scavenger solution can be adequately permeated into squid muscle tissues, and squid meat slices are processed into products after soaking by a conventional method; and the formaldehyde produced by the squid meat pieces and plant polyphenolic compound in the squid muscle tissue generate reaction under the high temperature condition in the processing procedure and produce nontoxic high molecule substances. The method is easy and feasible and can greatly reduce formaldehyde content in squid product.

Description

technical field [0001] The invention relates to the field of seafood processing, in particular to a scavenger for removing formaldehyde in squid products and an application method thereof. Background technique [0002] Formaldehyde is a highly toxic substance, has been identified as carcinogenic and teratogenic substances by the World Health Organization, is a recognized source of allergies, and is also one of potential strong mutagens. The lot of documents record, formaldehyde affects aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction to health effects. Acute formaldehyde poisoning through the mouth can directly damage people's mouth, throat, esophagus and gastric mucosa, and produce poisoning reactions at the same time. In mild cases, dizziness, coughing, vomiting, upper abdominal pain, and in severe cases, coma, shock, pulmonary edema, liver and kidney Dysfunction, leading to death from hemorr...
