Description

technical field [0001] The invention belongs to the technical field of food preservation and provides a sustained-release grape preservative with lasting effect. technical background [0002] With the development of science and technology and the gradual improvement of people's living standards, people's demand for fruits produced in different regions and seasons is gradually increasing. However, perishable fruits such as grapes have a short shelf life and are not easy to store. And people have put forward higher and higher requirements for fresh-keeping storage and transportation of fruits that are difficult to store such as grapes. For this, many inventors have provided the preparation method and usage of many effective long-acting preservatives and fresh-keeping tablets. [0003] Such as the Chinese patent "CN101133760 Grape Preservative" provides a main component consisting of calcium hypochlorite, sodium bisulfite, activated carbon, sodium polyacrylate, sodium chlorite,...
