Abstract

The invention relates to the field of agricultural product preservation and in particular relates to a method for preparing a litchi preservative by utilizing natural plants. According to the method disclosed by the invention, the essence parts of the raw materials can be obtained by virtue of various steps, the nutritive value is high, and the chelating time can be greatly shortened. Moreover, the various raw materials in the method are synergistic, the various steps are all linked with one another, the culture and preparation environment are controlled, harmful bacteria are reduced, and the litchi preservation time is greatly prolonged.

Description

technical field [0001] The invention relates to the field of preservation of agricultural products, in particular to a method for preparing a litchi preservative by using natural plants. Background technique [0002] "A concubine who rides the world of mortals laughs, but no one knows it's litchi." Litchi, a tropical fruit with thin skin and full of sweetness in Lingnan, is not only delicious, but also rich in sugar, which can replenish energy, fatigue and other symptoms; lychee meat is rich in vitamin C and protein; rich in vitamins, It can promote the blood circulation of micro blood vessels, prevent the occurrence of freckles, and make the skin smoother. [0003] Litchi is delicious, but it is difficult to keep it for a long time. After harvesting, it is stored at room temperature. If there is no proper packaging, the lychee skin will lose its original bright color and show browning symptoms within 1-2 days. The main reason is that Loss of moisture in the peel. The pee...
