Abstract

The invention discloses a mango preservative. The mango preservative comprises a folium cortex eucommiae ethanol extract preservative solution with the volume concentration of 1.0-3.0%. The invention also discloses a preparation method of the mango preservative, and the method comprises the following steps: crushing eucommia ulmoides leaves, adding an ethanol solution with the volume concentration of 30% into the crushed eucommia ulmoides leaves according to the solid-liquid ratio of 1: (15-20) g / mL, extracting under reduced pressure until the volume of the concentrated solution is 40-50% of the total volume of the initially added ethanol solution to obtain a eucommia ulmoides leaf ethanol extract concentrated solution; and dissolving the folium cortex eucommiae ethanol extract concentrated solution in water according to the volume ratio of (1-3): 100 to obtain the mango preservative. According to the method, the picked fresh mangifera indica is subjected to preservative and fresh-keeping, so that the residual harm of a preservative is reduced to the greatest extent, the nutritional ingredients and the fresh degree of the mangifera indica are maintained to the greatest extent, the metabolism process of the mangifera indica is delayed, the storage life of the mangifera indica is prolonged, high quality and high price are realized, and the maximum economic benefit is obtained.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping, and relates to a mango fresh-keeping agent and a preparation method thereof. Background technique [0002] At present, the postharvest loss rate of fruits in my country is very high, reaching more than 30% according to statistics. Nowadays, the antiseptic and fresh-keeping technologies in the post-harvest anti-corrosion and fresh-keeping process of fruits are mainly based on gas storage, cold storage, and chemical drug preservation. , high energy consumption for fresh-keeping equipment and other issues; the latter fresh-keeping technology will have residual hidden dangers, which may eventually lead to fruit quality and safety problems, and cannot fully guarantee human health. The natural antiseptic preservative derived from plants is low-carbon, environmentally friendly, low in cost, less in chemical residues, and easy to use. [0003] At present, the anti-corrosion and fresh-keeping tech...
