[0035] Rotate the above raw materials into the pulverizer, pulverize and stir evenly. Then carry out sieving process. Then add water according to the ratio of 1-4% of the mixture. Then stir well. Then dry it at 100-120°C. The drying time is 1-2 hours, and the moisture content after drying is 0.5%. Then make granules with a diameter of 2 to 2.5 mm in a vibrating sieve, and then dry in the shade to obtain a plum preservative.

Abstract

A manufacturing method for plums preserving agent, the present invention relates to a fruit preserving agent, specific manufacturing method for plums preserving agent. For preserving plums at present, one is putting preserving agent into package box or bag, the other is adopting low temperature storage. Because the current preserving agent contains noxious components, and low temperature storage affects the fruit shelf quality. The present invention includes the proportion of raw materials and manufacturing technology for preserving agent. The raw materials includes potassium permanganate, calcium hydroxide, ferrous sulfate, calcium oxide, sodium hypochlorite, anhydrous calcium chloride, zinc oxide, ascorbic acid, and sodium polyacrylate etc., zeolite as the carrier, in proportion mixed, crushed, stirring uniform and then sieving. Adding little water makes granule. The preserving agent made by this invention can adjust oxygen and carbon dioxide concentration around the fruits, decrease ethylene content, thus inhibiting fruits respiratory, delaying ripening, and reaching preservation purposes. The present invention method is simple, easy to implement, having obvious active effects compared with current products.

Description

technical field [0001] The invention relates to a fruit antistaling agent, in particular to a method for manufacturing the plum antistaling agent. Background technique [0002] At present, the preservation of plums after picking and storage and transportation has always been a problem that plagues producers, operators and scientific researchers. It is easy to deteriorate and rot in storage and transportation after mature harvest. And existing antistaling agent is because of containing poisonous composition, and the respiration of fruit in the storage and transportation process inhales toxic composition, can cause potential danger again to human body. Therefore, low-temperature refrigeration has become an ideal measure for long-distance transportation or storage of plums. However, the quality of fruit shelves after low-temperature refrigeration is not good, and browning is prone to occur. Therefore, for the preservation of plums, there are no good measures and preservative...
