Abstract

The invention discloses an antiseptic and fresh-keeping agent for litchi. In parts by weight, the antiseptic preservative components are: 20-50 parts of prochloraz, 10-30 parts of nano-silver sol, 5-10 parts of butanediol, 1-5 parts of surfactant, carboxymethyl shell Glycan / TiO 2 1-5 parts of composite material, 1-5 parts of glycosyl trehalose, 0.5-1 part of preservative, 0.1-0.5 part of carrageenan and 100-800 parts of water. The present invention also provides a preparation method of the above-mentioned antiseptic and antistaling agent and a method for using the above-mentioned antiseptic and antistaling agent to keep litchi fresh. It can significantly control the skin shrinkage and fruit rot of litchi through the combination of sterilization and moisturizing technology, effectively prolong the storage period and shelf life of litchi, improve commodity value and economic benefits; at the same time combined with ultrasonic soaking treatment, chemical preservation and physical preservation The bactericidal compound is safe and non-toxic; the preparation method is simple, efficient and safe, and has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of fruit and vegetable storage and preservation, in particular to an antiseptic and preservation agent for litchi, a preparation method and a use method. Background technique [0002] Litchi (Litchi chinensis Sonn.) belongs to Sapindaceae (Sapindaceae), is a famous fruit native to southern my country, and is one of the most competitive fruits in the international market. Lychee is sweet, sour, warm in nature, enters the heart, spleen, and liver meridian; it can stop hiccups and diarrhea, and is a good food therapy for intractable hiccups and early diarrhea. At the same time, it can nourish the brain and strengthen the spleen. The effect. Because lychee fruit is harvested in high temperature season in midsummer, and its special structure, the peel has scale-like protrusions, bright red and purple red, and the flesh is translucent and creamy when it is fresh, with a delicious taste. It is easy to brown and ro...
