According to the data, the rot and spoilage of fresh grape during storage and transportation are as high as 20% to 25%, and the storage, transportation and preservation of fresh grape has become the main target for post-natal preservation. Preservatives and preservatives are essential technical measures to maintain the quality of products and extend the shelf life of grapes after harvest. Combined with the control of temperature, humidity and gas composition, they can greatly inhibit and kill the growth and reproduction of rotting microorganisms. It can also inhibit the occurrence of grape senescence and physiological diseases. Pre-harvest preservatives use various substances with bactericidal and preservative effects, such as food additives and microbiological sources, as the main raw materials. They perform scientific compounding techniques and use the chemical and physical properties of active substances and additives to compound suspension solutions (water). (agent), so that the active material exists in the molecular state in water, to solve the problem of product specifications such as homogeneity, stability, long-term performance. Formulated as a homogeneous and stable solution. With high permeability and high absorption rate, no visible spots are found on the treated fruits and vegetables. The product is highly hygienic and safe. Residues of active substances in fruits and vegetables after treatment are lower than those allowed by GB2760-1996 and meet the requirements for green food production. When used, add water to dilute, and then carry out pre-harvest spraying or dipping of grape fruit, and the surface is dried after water evaporation and drying. When harvesting, fruit can be packaged individually and gently and gently. In order to tie in storage and preservation technology, it is necessary to emphasize that one-time packing measures are better. The use of this technical method can reduce the amount of grape fruit before harvest and reduce the surface microorganisms on the fruit by more than 15%, which greatly reduces the circulation loss during storage and transportation.
