[0021] A composite antistaling agent is formed by mixing components as described in Table 1.

[0022] Table 1 (unit: g)

[0023]

[0024] The preparation method of Zanthoxylum bungeanum extract is as follows: pre-freeze the dried fruit of Zanthoxylum bungeanum at -20°C to -65°C for 0.5 to 1 hour, then pulverize at 0°C to 5°C, pass through a 30 to 50 mesh sieve, and then crush the 5kg of Zanthoxylum bungeanum fruit is extracted with supercritical carbon dioxide, and ethanol is used as an entraining agent. Equivalent to 20g dried fruit of Zanthoxylum bungeanum), sealed and stored at 4°C.

[0025] Preparation of Zanthoxylum bungeanum leaf extract: Pulverize red Zanthoxylum bungeanum leaves, add methanol with a concentration of 50% according to the ratio of material to liquid 1g: 25ml as an extractant, shake at room temperature, separate the supernatant, and concentrate and dry the supernatant to obtain the extract. paste, disperse the extract in purified water, the ratio of ...

Abstract

The invention belongs to the technical field of food preservation, and particularly relates to a composite preservative and an application method thereof. The composite preservative for meat comprises the following components in parts by weight: 2-5 parts of chitosan, 1-2 parts of tea polyphenol, 1-2 parts of green tea powder, 8-15 parts of Zanthoxylum bungeanum extract, 5-10 parts of Zanthoxylum bungeanum leaf extract, 15-20 parts of bamboo vinegar solution and 50-80 parts of water. The bamboo vinegar solution is a product prepared by cooling a vaporizing liquid which is obtained by heating and decomposing bamboo at high temperature. The composite preservative for meat adopts pure natural plant components, is free of antibiotics and conventional bactericides, and thus, is safe and environment-friendly in components; and after special proportioning, the product has broad-spectrum antimicrobial effect, and effectively inhibits the microbes from growth in the low-temperature preservation process of fresh pork and other meat products, thereby prolonging the storage time and shelf life of fresh meat.

Description

technical field [0001] The invention belongs to the technical field of food fresh-keeping, and in particular relates to a composite fresh-keeping agent and a using method thereof. Background technique [0002] The preservation and preservation of meat has been an important subject of human research since ancient times. With the changes in the lifestyle and rhythm of modern people, the traditional meat preservation technology can no longer meet people's needs. It is imperative to study the preservation technology of meat in depth. Row. Scholars at home and abroad have conducted extensive research on meat preservation. At present, it is believed that any fresh-keeping method has disadvantages, and comprehensive fresh-keeping technology must be adopted to give full play to the advantages of various preservation methods to achieve the purpose of complementary advantages and multiplied effects. The spoilage of meat is mainly caused by three factors: (1) microbial contamination,...
