Problems solved by technology

But there are also some shortcomings, mainly because the release period is short, the preservation effect is uneven, and it is difficult to guarantee the effect; the preparation method is complicated and complicated; the production cost is high, and the source of raw materials is narrow; some raw material components are harmful to the human body
[0003] Litchi is a popular fruit, but its short shelf life has seriously affected the long-distance transportation and sales of lychees.

Abstract

The invention provides a litchi preservative which consists of the following components in parts by mass: 3-5 parts of lignin, 2-3 parts of sucrose ester, 1-1.5 parts of sodium sorbate, 0.8-1.2 parts of citric acid, 1-1.5 parts of potassium chloride, 0.5-0.6 part of calcium stearate, 0.2-0.3 part of chitin and 180-190 parts of water. The litchi preservative provided by the invention is simple to prepare, reasonable in formula and low in cost; and when in use, the litchi preservative is convenient to operate, realizes a good preservation effect and can prolong the litchi preservation time by 20-30 days.

Description

technical field [0001] The invention relates to a litchi fresh-keeping agent. Background technique [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 seasons in different regions is gradually increasing. People have put forward higher and higher requirements for fresh-keeping storage and transportation of fruits that are difficult to store. Existing fruit fresh-keeping technology generally is to make fresh-keeping film, and fresh-keeping film does have certain progress in room temperature or low temperature fresh-keeping, long-term fresh-keeping, transportation fresh-keeping aspect. But there are also some deficiencies, mainly because the release period is short, the preservation effect is uneven, and it is difficult to guarantee the effect; the preparation method is complicated and complicated; the production cost is high, and the source of raw materials is narro...
