Benefits of technology

This new compound described in this patents improves upon previous methods such as adding chemical agents or enzymes into foodstuff without affecting their taste quality. Its use helps maintain flavor integrity during storage even after long periods of time due to its ability to kill harmful germs overall.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the quality of preserved fried fish products during storage without compromising their taste, smell, texture, appearance, odor, nutritional content, and environmental impact caused by refrigerated chilling methods that involve cooling down parts before storing them again. Current solutions require expensive chemical agents like nitrogen bleach, sulfur dioxiridon tetraoxysulfonic acid, citric acid, ammonothermal lycopene complexes, formaldehyde resins, beta glucans, gamma ray irradiation, hydroxypropyltriazolidone, lithography techniques, ion exchange chromatographic analysis, and various combinations therapies involving different types of stabilizers/solvents.

Embodiment 1

[0027] (1) Raw material processing: Select healthy chickens that pass the inspection and quarantine, slaughter, drain the blood, remove the viscera, wash, and then pre-cool the chicken body to reach a temperature of 10°C.

[0028] (2) Pre-sterilization: Soak in ozone water with a temperature of 2°C and a concentration of 10g / mL for 10 minutes to kill the microorganisms attached to the surface of the chicken carcass and in the cavity, reduce the initial microbial content, and further reduce the temperature of the chicken body to 4 ℃, then drain the water for later use;

[0029] (3) Preparation of coating solution: prepare 10kg of coating solution, the preparation process and formula are as follows:

[0030] Get 0.01kg of ascorbic acid (Vc), 0.01kg of tea polyphenols, add 9.178kg of water to make the above two substances dissolve completely, then add 0.15kg of glacial acetic acid, fully mix and prepare an acetic acid composite solution for subsequent use;

Abstract

The invention discloses a complex preservation method of cold fresh chicken. The method comprises pre-sterilizing chicken by soaking the chicken in 2-4 DEG C 4-10g/mL ozone water for 10-25min; preparing a film coating solution; and soaking the pre-sterilized drained chicken in the film coating solution for 1-3min, draining, and refrigerating at 4-8 DEG C. The invention can effectively prolong thepreservation period of the chicken. The chicken treated by the inventive method can keep for about 28 days at 4-8 DEG C, but untreated cold fresh chicken only keeps for 3-4 days at 4-8 DEG C.
