Abstract

The invention discloses fresh keeping coating film fluid for plums, and a preparation method of the fresh keeping coating film fluid in the technical field of fresh keeping of fruits and vegetables. The fresh keeping coating film fluid comprises enveloping fluid and sterilization fluid, wherein the ratio of the mass parts of the enveloping fluid to the mass parts of the sterilization fluid is 9 to 1, the enveloping fluid is made from the following components in parts by mass: 11-13 parts of bleached shellac, 20-22 parts of glycerine and 9-12 parts of sucrose ester, and sterilization fluid is made from the following components in parts by mass: 5-7 parts of a licorice root extracting solution and 6-9 parts of a lophatherum herb extracting solution. The method for preparing the fresh keeping coating film fluid comprises four steps of preparing the enveloping fluid, preparing the licorice root extracting solution, preparing the lophatherum herb extracting solution and performing mixing. The fresh keeping coating film fluid disclosed by the invention is used for wrapping the surfaces of the plums, the evaporation and the respiration of water of the plums can be restrained, organic acid and vitamin C in the plums can be well reserved, and the nutrient value and the eating quality of the plums are high.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping of fruits and vegetables, and in particular relates to a fresh-keeping coating solution for plums and a preparation method thereof. Background technique [0002] Plum is a drupe fruit of the family Rosaceae and one of the traditional fruits in my country. It is very popular among consumers for its aroma, sweetness, crispness and coolness. The fruit is rich in nutrition, containing sugar, acid, protein and various vitamins and minerals, etc., and has high nutritional value. Since the ripening period of plums is concentrated in June to July, and the temperature is high during this period, they are particularly susceptible to microbial infection and rot and deterioration due to their own physiological changes during storage. Plum is a climacteric fruit with fast post-ripening speed, which is not resistant to storage and has a short shelf life. After 2-3 days at room temperature, the commercia...
