Abstract

The invention relates to the technical field of fruit and vegetable storage and preservation, and discloses a litchi preservation agent. In parts by weight, the preservative components are: 20-50 parts of iprodione, 10-30 parts of nano-silver sol, 5-10 parts of ethylene glycol, 1-5 parts of surfactant, carboxymethyl chitosan Sugar/TiO 2 1-5 parts of composite material, 1-5 parts of glycosyl trehalose, 0.1-0.5 parts of thickener and 100-800 parts of water. Also provided are a preparation method of the above-mentioned antistaling agent, and a method for using the above-mentioned antistaling agent to preserve the litchi. The antistaling agent can significantly control the skin shrinkage and fruit rot of lychees through the combination of sterilization and moisturizing technology, effectively prolong the storage period and shelf life of lychees, and improve commodity value and economic benefits; Treatment, chemical preservation and physical sterilization are combined, 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 fresh-keeping, in particular to a litchi fresh-keeping agent, a preparation method and a litchi fresh-keeping 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 rot...
