Fresh keeping agent composition for mandarins and preparation method of fresh keeping agent composition

Abstract

The invention discloses a fresh keeping agent composition for mandarins and a preparation method of the fresh keeping agent composition. The fresh keeping agent composition consists of the following components in percentage by weight: 1.25-5% of tropic ageratum essential oil, 3.75-15% of anhydrous alcohol, 5-25% of tween and the balance of solvents. Through adoption of the fresh keeping agent composition for mandarins, the growth of penicillium italicum, penicillium digitatum and penicillium expansum can be significantly restrained; and when fresh keeping agents are used for performing fruit immersion treatment on the mandarins, the water loss rate and the rotting rate of the mandarins in the storage process can be significantly reduced. The fresh keeping agent composition for mandarins disclosed by the invention is simple in formula components, simple in compounding technology, natural, environmentally-friendly, and non-toxic, conforms to green, environmental protection and ecologicalcivilization construction ideas at present, and has favorable development and application prospects.

Description

technical field [0001] The invention belongs to the technical field of fruit fresh-keeping, and in particular relates to a tangerine fresh-keeping agent composition and a preparation method thereof. Background technique [0002] Fujian Yongchun mandarin orange is one of the traditional famous and high-quality products in Yongchun County, and enjoys a high reputation in the domestic and foreign markets. Foreign fruit merchants call it "Oriental Best Fruit". The ripening period of tangerine fruit is from October to November, which is a relatively high temperature climate season, so the fruit is vulnerable to post-harvest pathogen infection, resulting in fruit rot and quality decline. Penicillium italicum and Penicillium digitatum mainly caused penicillium and green mold during postharvest and storage and transportation of mandarin oranges. And Penicillium expansum can also cause Penicillium disease, and the patulin secreted in the infected fruit is a neuromycotoxin, which wi...

AI Technical Summary

Problems solved by technology

And Penicillium expansum can also cause Penicillium disease, and the patulin secreted in the infected fruit is a neuromycotoxin, which will cause potential food safety problems, and they together cause serious postharvest citrus fruits rot, which can cause serious agricultural economic losses and hinder the development of the citrus industry

[0003] At present, chemical fungicides such as imazalil, cybendazole, sodium o-phenylphenate, fludioxonil, pyrimethanil, bacoud and prochloraz are mainly used to preserve the freshness of citrus fruits, and the long-term use of chemical fungicides It will increase the drug resistance of pathogenic bacteria and cause many environmental and social problems. It does not conform to the theme of today's green development and ecological civilization construction. Therefore, it is imperative to develop environmentally friendly fresh-keeping products.
