Siraitia grosvenorii water-retaining bactericidal coating liquid and preparation method thereof

Abstract

The invention discloses siraitia grosvenorii water-retaining bactericidal coating liquid. The siraitia grosvenorii water-retaining bactericidal coating liquid consists of the following components in percentage by mass: 15-20 percent of lac, 0.1-0.2 percent of monoglyceride, 0.3-0.5 percent of sodium carbonate, 0.001-0.004 percent of tea saponin, 0.002-0.004 percent of myristic acid and 0.001-0.002 percent of aminooxy acetic acid. According to the coating liquid, the freshness retaining cost can be reduced, cold-resistant pathogenic bacteria are not generated, the breathing of siraitia grosvenorii and the growth of surface pathogenic bacteria can be inhibited, and thus the rot of the siraitia grosvenorii is avoided. The water-retaining bactericidal coating liquid is high in stability and can be stored for half a year without deterioration. According to the water-retaining bactericidal coating liquid disclosed by the invention, the surface of the siraitia grosvenorii can be bright, and after the siraitia grosvenorii is stored for 100 days, the bad fruit rate is less than 2 percent, the water loss rate is less than 10 percent, and the taste is kept fresh.

Description

technical field [0001] The invention belongs to the field of fruit preservation, and in particular relates to a water-retaining and sterilizing coating liquid for Luo Han Guo. Background technique [0002] Luo Han Guo is a tropical fruit mainly produced in Guangxi. If no fresh-keeping treatment is carried out during transportation or storage to the north after picking, it is very easy to cause rapid deterioration and rot of Luo Han Guo due to respiration or residual harmful bacteria on the surface. Most of the existing fresh-keeping methods are cold storage, but the cost of cold storage is relatively high, and cold-resistant pathogenic bacteria are likely to be produced. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects, and provide a water-retaining and sterilizing coating liquid for Luo Han Guo and a preparation method thereof. [0004] In order to solve the problems of the technologies des...
