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.

Embodiment 1

[0029] The preparation method of orange preservative composition, comprises the steps:

[0030] (1) Take each component by weighing as follows:

[0031]

[0032] Described solvent is made up of 3% sodium carbonate solution and 0.5% carboxymethyl chitosan solution with the volume ratio of 1: 3;

[0033] (2) Dissolving the red thistle essential oil in absolute ethanol, stirring, vortexing to a uniform state, and obtaining the oil phase;

[0034] (3) Add Tween-80 to the above oil phase, stir, and vortex to a uniform state;

[0035] (4) After mixing 3% sodium carbonate solution and 0.5% carboxymethyl chitosan solution with a volume ratio of 1:3, ultrasonic treatment was performed for 20 minutes to obtain a solvent. The power of the above-mentioned ultrasonic treatment was 200W, and the frequency was 40kHz;

[0036] (5) Add the above-mentioned solvent to the material obtained in step (3), and mix evenly to obtain the citrus preservative composition.

Abstract

The invention discloses a tangerine antistaling agent composition and a preparation method thereof. It consists of the following components in percentage by weight: 1.25-5% of cardamom essential oil, 3.75-15% of dehydrated alcohol, 5-25% of Tween and Solvent balance. The tangerine antistaling agent composition of the present invention can significantly inhibit the growth of Penicillium italicum, Penicillium digitatum and Penicillium extensa, and use the antistaling agent to treat citrus tangerine fruit soaking, and significantly reduce the water loss of tangerines during storage rate and decay rate. The tangerine antistaling agent composition of the invention has simple formula components and simple preparation process, is natural, environmentally friendly and non-toxic, conforms to the current concept of green, environmental protection and ecological civilization construction, and has good 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...
