Preparation method of special efficient sustained release cold storage agent for supporting fruit and vegetable storage and transportation
A preparation method of a special efficient sustained release cold storage agent for supporting fruit and vegetable storage and transportation comprises steps as follows: three raw materials including cyclodextrin, glycerine and sodium polyacrylate are prepared in percentage by weight; under the condition of the room temperature, cyclodextrin is added to water and is stirred until cyclodextrin is sufficiently dissolved to obtain a transparent liquid, and then glycerine is slowly added and stirred until glycerine is sufficiently dissolved; sodium polyacrylate is finally added and stirred until polyacrylate is sufficiently dissolved to obtain a colloidal liquid, and the cold storage agent is obtained; the prepared cold storage agent is packaged. The cold storage agent prepared with the method is non toxic, odorless, safe and environment friendly, has a remarkable refrigeration effect, can be recycled, cannot shrink, and cannot produce deionized water; the preparation process does not require heating, and the operation method is simple and feasible; the sustained release cold storage agent can be recycled, has low cost and good effect, is applicable to large scale production and facilitates popularization.
