Abstract

The invention relates to the technical field of fresh keeping of vegetables, in particular to a fresh-keeping agent special for crowndaisy chrysanthemum and a preparation method of the fresh-keeping agent. The fresh-keeping agent is prepared from a curcuma zedoaria extract, a turmeric fermented product, a pomegranate rind extract, a Chinese gall extract, a chili pepper fermented product, a salicylate ester, a tulip extract, cyclodextrin, konjac powder, a passion fruit extract and a chrysanthemum coronarium extract. The preparation method comprises the following steps of firstly, thoroughly mixing the curcuma zedoaria extract with the pomegranate rind extract, the Chinese gall extract, the tulip extract, the passion fruit extract and the chrysanthemum coronarium extract; performing treatment with a high-static pressure electric field, performing transferring to a stirrer, adding the cyclodextrin and the konjac powder while during stirring, and after the cyclodextrin and the konjac powder are added, continuing performing stirring for 10min; then, adding the turmeric fermented product and the chili pepper fermented product, performing microwave treatment, then, adding the salicylate ester and performing uniform stirring so as to obtain the fresh-keeping agent. The fresh-keeping agent is used, so that the respiratory intensity of the chrysanthemum coronarium can be restrained, theaccumulation of the content of ethylene can also be restrained, and the reduction of nutrient substances of minerals, VC, chlorophyll and the like, in the chrysanthemum coronarium can be delayed.

Description

technical field [0001] The invention relates to the technical field of vegetable fresh-keeping, in particular to a fresh-keeping agent specially used for chrysanthemum chrysanthemum and a preparation method thereof. Background technique [0002] According to ancient Chinese medicine books: Chrysanthemum chrysanthemum is sweet, pungent, flat, non-toxic, and has the effects of "relieving the heart, nourishing the spleen and stomach, eliminating phlegm, and benefiting the stomach". Chrysanthemum chrysanthemum is a semi-cold-resistant vegetable that likes cold and humid climates. Due to its large leaf surface area, high water content, and crisp and tender tissues, the water evaporates quickly after harvesting, and it is susceptible to mechanical damage. The respiration is strong and produces a lot of respiration Chrysanthemum chrysanthemum is prone to yellowing, wilting, and rot, which affects the nutritional value, disease resistance and appearance quality of chrysanthemum chry...
