Abstract

The invention discloses a biological fresh-keeping agent extracted from idesia polycarpa and preparation and application thereof. The preparation method comprises the steps of preparing an extract, preparing an extracting solution, emulsifying and mixing. The biological fresh-keeping agent extracted from idesia polycarpa is used for fruit and vegetable fresh keeping. The biological fresh-keeping agent extracted from idesia polycarpa is used for performing fresh keeping on fruits and vegetables, is safe and free of toxicity and pollution, can replace chemical pesticide and preservative for fresh-keeping of fruits and vegetables, and avoids environmental pollution of chemical fungicide. The preparation method of the fresh-keeping agent is easy to implement, low in cost and applicable to large-scale industrial production, and preparation is convenient.

Description

technical field [0001] The invention belongs to food antistaling agents, in particular to a biological antistaling agent extracted from Jatropha tomentosa and its preparation and application. Background technique [0002] Idesia polycarpa Maxim (Idesia polycarpa Maxim) is a deciduous tree of the genus Idesia polycarpa Maxim. There is only one species of this genus in the world. It is mainly produced in Japan, North Korea, the Russian Far East and China. southern provinces. Jatropha Maoye is a unique woody oil plant species in my country. It has the characteristics of wide distribution, low requirements on soil and climate, and strong adaptability. It is suitable for planting in low-quality, barren slopes, tidal flats, and mountains. , easy to promote, and easy to popularize". It is an economic crop with high yield and high economic value, and has great application value and development potential. According to data reports: Jatropha jatropha has a fruit-producing period of ...
