Embodiment 1

[0031] 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;

[0032] 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;

[0033] 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;

[0034] 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 antistaling agent. Each liter of the composite biological antistaling agent contains the following components: 0.3-0.4g nisin, 0.3-0.5g lysozyme, 40-70mL garlic juice, 4- 9mL rosemary extract and balance water. The invention also discloses the application of the above-mentioned composite biological antistaling agent in the preservation of drunken snails. The composite biological antistaling agent of the present invention selects natural antistaling agent Streptococcus lactis, lysozyme and plant source component garlic juice, rosemary ethanol extract as composite biological antistaling agent to carry out fresh-keeping to drunk snails, in garlic juice and rosemary ethanol extract Contains a large amount of biologically active substances, which can chemically react with microorganisms in drunken snails, thereby effectively inhibiting the growth of microorganisms in drunken snails. The composite biological preservative of the present invention can prolong the shelf life of drunken snails as a preservative for drunken snails period, it can also improve the food flavor of drunken snails, and has certain health effects 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. [0002] technical background [0003] 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, ...
