A kind of citrus biological composite anti-mildew preservative and its preparation and use method

Abstract

The citrus biological compound anti-mildew preservative of the present invention is composed of the following raw materials in parts by mass and volume: 1 part of glacial acetic acid, 2-3 parts of chitosan, 1.5-2 parts of Bacillus amyloliquefaciens HRH.317 fermentation broth, Tween-80 ?1.5-2 parts, NaCl? 0.3-0.5 parts, 93 parts of distilled water. The preparation method of the preservative is: first add glacial acetic acid to distilled water to make an acetic acid solution; then add chitosan, Bacillus amyloliquefaciens HRH317 fermented liquid, Tween-80 and NaCl to the acetic acid solution, and stir evenly. . The method of using this preservative is: wash the citrus without damage and disease with tap water and then immerse it in 0.1% sodium hypochlorite solution for disinfection for 1-2 minutes. After taking it out, wash the sodium hypochlorite with sterile water and dry it. Soak in the preservative for 30-40 seconds, take out and dry completely, then pack them in PE fresh-keeping bags, put 25-40 fruits in each bag, put them in plastic baskets, and store them in a room temperature of 18-23°C and a relative humidity of 70%- Store under the condition of 80% humidity or store at a storage temperature of 4-6°C and a relative humidity of 70%-80%.

Description

technical field [0001] The invention relates to the technical field of citrus preservation, in particular to the preservation of citrus by adopting a biological anti-mold antistaling agent and a method for preparing and using the anti-mold antistaling agent. Background technique [0002] Fruits and vegetables are one of the main foods for human beings, but they are prone to spoilage due to regional and seasonal influences. The spoilage of fruits and vegetables will cause unnecessary money loss and reduce the quality of fruits and vegetables. Among them, food-borne pathogens can produce a large amount of toxins, causing people to suffer from diseases such as digestive tract diseases, immune diseases and inflammation. Traditional chemical anti-mildew preservatives are highly toxic and can easily cause human allergies and poisoning, while the new biological preservatives are only proteins, polypeptides, certain lipids and organic acids, etc., which have no or very toxic side ef...
