Problems solved by technology

[0005] Chen Xiaoe and others published the article "Study on Ultra-high Pressure Sterilization Technology of Pickled Raw Mud Snails" (2009, 17(4): 77-79) in "Grain, Oil and Food Science and Technology". Some effects have been achieved in inhibiting harmful microorganisms in the mud snail, but the operation cost is high, which is not conducive to industrial production

Embodiment 1

[0030] 1) The purchased fresh mud snails are made into drunk snails according to a certain processing technology, the garlic is peeled, the intact individuals are selected, washed and dried, and the juice is squeezed with a clean juicer;

[0031] 2) Garlic juice is filtered with a clean 200-mesh filter cloth, and the filtrate is centrifuged under a refrigerated centrifuge at 5000r / min for 20min, and then the supernatant is taken for later use;

[0032] 3) Dry the rosemary purchased from a traditional Chinese medicine store at 65° C., crush and pass through a 40-mesh sieve first, and then pass through an 80-mesh sieve;

[0033] 4) Use 95% food-grade ethanol according to the ratio of solid to liquid to be 1:8, and extract by shaking at 40°C for 3 hours, then assisted extraction with low-frequency ultrasound at 50°C for 1.5h, vacuum filtration, repeat the above steps three times, and combine the filtrates. Concentrate by rotary evaporation to obtain the rosemary extract stock sol...

Abstract

The invention discloses a composite biological fresh-keeping agent. Each liter of the composite biological fresh-keeping agent comprises the following components by mass: 0.3-0.4g of nisin, 0.3-0.5g of lysozyme, 40-70mL of garlic juice, 4-9mL of rosemary extract and the balance of water. The invention also discloses the application of the composite biological fresh-keeping agent in the anticorrosion of drunk bullacta exarata. The composite biological fresh-keeping agent of the invention is prepared by selecting natural fresh-keeping agents: the nisin, the lysozyme, the garlic juice, a plant-sourced component, and the rosemary alcohol extract. The composite biological fresh-keeping agent can performs fresh keeping on the drunk bullacta exarata. The garlic juice and the rosemary alcohol extract contain a large amount of biological active substances capable of setting off chemical reaction with microorganisms in the drunk bullacta exarata, so that growth of the microorganisms in the drunkbullacta exarata can be effectively inhibited. The composite biological fresh-keeping agent, as a fresh-keeping agent, can prolong the shelf life of the drunk bullacta exarata, and improve the food flavor of the drunk bullacta exarata, and has certain health-care efficacy on the human body.

Description

technical field [0001] The invention relates to a composite biological antistaling agent, and also relates to the application of the composite biological antistaling agent in the preservation of drunk snails, belonging to the technical field of food processing and production. technical background [0002] The mud snail meat is delicious, nutritious, rich in protein, polyunsaturated fat, minerals and essential trace elements, etc.; Such as medicinal value, the ancient folks had the practice of soaking food in wine to prevent tuberculosis and pharyngitis, which was deeply loved by consumers. However, due to the high water content and rich nutrition, the mud snails are very susceptible to microbial contamination and spoilage. The drunken snails are raw aquatic products, and their special eating methods. In addition, the current production of drunken snails is simple and poor in hygienic conditions, and most of them are manually operated. , low degree of mechanization, etc., re...
