Fresh-keeping agent and fresh-keeping method for grosvenor momordica fruits

Abstract

The invention relates to the technical field of fresh-keeping, in particular to a fresh-keeping agent and fresh-keeping method for grosvenor momordica fruits. The fresh-keeping agent consists of fresh-keeping components and a film-forming agent. The fresh-keeping components consist of grosvenor momordica fruit seed essential oil, clove essential oil, herba pogostemonis essential oil, licorice extractive, grape seed essential oil and lotus leaf extractive. The fresh-keeping components of the fresh-keeping agent employ four essential oil components as main fresh-keeping active ingredients. The essential oil has the characteristics of small molecules, good permeability, high content of active ingredients and easy decomposition, and the fresh-keeping agent is an effective fresh-keeping agent,and has good antibacterial, bactericidal and anti-oxidation effects. The film-forming agent is mainly composed of the following components including burdock oligosaccharide, chitosan, sodium alginateand konjac gum, and the components have a bacteriostatic effect besides a film-forming characteristic, can slow down the respiration of the grosvenor momordica fruits and form a protective film on thesurface of each grosvenor momordica fruit, and enable mogroside V and total mogroside to be effectively gathered in the grosvenor momordica fruits.

Description

【Technical field】 [0001] The invention relates to the field of fresh-keeping technology, in particular to a monk fruit fresh-keeping agent and a fresh-keeping method thereof. 【Background technique】 [0002] Luo Han Guo (scientific name: Siraitia grosvenorii) is a traditional medicine and food homologous plant in my country. The history of folk medicine in Guangxi has been more than 300 years. It is also rich in various nutrients such as vitamin C, E, fructose, essential amino acids, trace elements, etc., and contains various active ingredients such as flavonoids, polysaccharides, sweet glycosides, and polyphenols. The market welcomes it. Recent studies have shown that the main active ingredient in Luo Han Guo is Mogroside. Since the 1970s, foreign scholars have carried out research on Mogroside. So far, 11 species have been isolated and identified from the fruit of Luo Han Guo. Cucurbitane triterpene glycoside compounds, of which mogroside V is the most important saponin compo...

[0003] However, at present, Luo Han Guo is often preserved in the form of dried fruit. The traditional processing method is to ripen the fresh fruit of Luo Han Guo in a ventilated place at room temperature until the peel turns yellow, and then dry it at a temperature of 50°C. According to the research, the saponin content of the fresh fruit of Luo Han Guo is much greater than that of the dried fruit, but the fresh fruit of Luo Han Guo has a short shelf life and is not easy to process. Therefore, if we can effectively study the preservation method of the fresh fruit of Luo Han Guo, it will further strengthen the extraction of saponins of Luo Han Guo and effectively ensure the quality of the fruit. main active ingredient in
