The invention discloses a fresh-keeping agent for fruits and vegetables and a preparation method thereof. Its composition and mass percentage are 20-30% of lacquer wax emulsion, 0.5-2% of sumac seed kernel oil, 45-70% of water, and 5-15% of ethanol. %, nano titanium dioxide 0.05-0.1%, propylene glycol or glycerin 0.5-3%, Tween 0.5-2%, silane coupling agent 0.01-0.02%, chitosan 1-2%, acetic acid 0.1-0.5%, malt Dextrin 0.5-2%, sucrose fatty acid ester 0.1-1%, glyceryl monostearate 0.5-2%; After the film, the gloss and commerciality of vegetables and vegetables are good, and the shelf life of fruits and vegetables is prolonged.

Description

technical field

[0001] The invention relates to the field of fresh-keeping processing of fruits and vegetables, in particular to a fresh-keeping agent for fruits and vegetables and a preparation method thereof. Background technique

[0002] The annual production, sales and export of fruits and vegetables in my country is very large, but in the process of transportation and storage, the loss caused by mildew and rot reaches 25%-30%, and the serious one is as high as 40%. Therefore, the research on fruit and vegetable preservation technology has obvious social and economic benefits, and it is also a hot spot in current research at home and abroad. In recent years, cold storage, modified atmosphere storage, decompression storage, modified atmosphere packaging film and chemical treatment have been widely used in recent years. However, these fresh-keeping technologies have high energy consumption, large investment or toxic side effects. With the development of modern fresh-keepi...
