Abstract

The invention relates to the technical field of after-harvest preservation of citrus and particularly relates to an after-harvest plant preservative containing a silktree albizia bark extract and usedfor citrus. The preservative comprises the following components: 6.25-50 parts of the silktree albizia bark extract, 0.5-2.0 parts of a film former, 0.5-1.0 part of a cosolvent, 0.5-1.5 parts of a preservative, 0.5-1.0 part of a pH value regulating reagent, 0.5-2.0 parts of an osmoregulation agent, 0.5-3.0 parts of an antioxidant and 1000 parts of water. The novel after-harvest preservative for citrus is prepared by taking the natural Chinese herbal medicine silktree albizia bark extract as the main effective component, the advantage of obvious bacteriostatic effects of the silktree albizia bark extract is fully utilized, and other auxiliary components are reasonably and scientifically blended, so the preservative has the characteristics of good preservation effects, no chemical residue,no health hazard to a human body, no pollution to the environment and the like and has good application values.

Description

technical field [0001] The invention relates to the technical field of post-harvest preservation of citrus, in particular to a post-harvest plant preservation agent for citrus containing the extract of Albizia Julibrissin. Background technique [0002] Citrus is the largest category of fruit in the world, the second largest category of fruit in my country except apples, and the third largest agricultural product in international trade after wheat and corn. Citrus postharvest rot is one of the main problems in the storage and distribution of citrus. There are more than 20 types of microbial diseases during postharvest storage of citrus, such as blue mold and green mold caused by Penicillium italicum and Penicillium digitatum These two diseases are the most prone to postharvest diseases of citrus, and 90% of the rot rate of citrus after harvest is caused by these two diseases. Therefore, the research on post-harvest storage and fresh-keeping technology of citrus has been pai...
