Abstract

The invention belongs to the technical field of vegetable freshness preservation, and particularly relates to a vegetable preservative and a preparation method thereof. Folium artemisiae argyi extracting liquid, aloe extracting liquid and patrinia scabiosaefolia link extracting liquid are respectively extracted from folium artemisiae argyi, aloe and patrinia scabiosaefolia link, the extracting liquid is mixed and concentrated to obtain concentrated extracting liquid, and nanometer titanium dioxide is add into ethanol to obtain ethanol dispersion liquid of the nanometer titanium dioxide; imazalil sulfate, a plant growth regulator and an antioxidant are successively dissolved in deionized water, concentrated extracting liquid and the ethanol dispersion liquid of the nanometer titanium dioxide are added, and the mixture is uniformly mixed to obtain the vegetable preservative. A small amount of antibacterial agent nanometer titanium dioxide is added into the vegetable preservative, the matching ratio of the plant growth regulator, an antioxidant, plant extracting liquid and the antibacterial agent is reasonably controlled, the composite synergism effect is achieved, and the prepared vegetable preservative has the effects of keeping green and inhibiting mould growth, can effectively keep the vegetable freshness, and prolong the storage time.

Description

technical field [0001] The invention belongs to the technical field of vegetable fresh-keeping, and in particular relates to a vegetable fresh-keeping agent and a preparation method thereof. Background technique [0002] Due to the substantial improvement of people's living standards, the awareness of healthy diet is weak, and the work pressure is increased, and the amount of exercise is reduced. Therefore, the number of people with affluent diseases such as high blood pressure, high blood fat, and obesity has increased significantly. In recent years, more and more people have noticed that affluenza is a serious threat to our health, and people's awareness of healthy eating habits has gradually increased. A healthy diet requires us to consume less animal protein and eat more fruits and vegetables. Therefore, the consumption of vegetables is increasing year by year. However, due to various reasons such as physiological aging, microbial invasion and mechanical damage before a...
