[0020] Anti-mildew and fresh-keeping effect of corn gas phase

[0021] The microcapsule essential oil is mixed with anethole 20, cinnamaldehyde 15, citral 50, and salicylaldehyde 15 in parts by weight to prepare a gas-phase slow-release anti-mold preservative for corn storage, according to 300g / m 3 The dosage of the silo volume was put into the corn silo, the moisture content of the corn was 9%, and the corn was stored at a temperature of 35°C and a relative humidity of 90% for 45 days. Mildew does not occur, and the mildew rate can be reduced by 80% after 60 days of storage.

example 2

[0023] Anti-mildew and fresh-keeping effect on the gas phase of oilseed flowers

[0024] The microcapsule essential oil is mixed with anethole 30, cinnamaldehyde 20, citral 35, and salicylaldehyde 20 in parts by weight to prepare a gas-phase slow-release anti-mold preservative for peanut storage, according to 450g / m 3 The dose of the storage bin volume was put into the peanut storage bin, the moisture content of the peanuts was 8%, and the peanuts were stored at a temperature of 35°C and a relative humidity of 90% for 30 days. Mildew does not occur, and the mildew rate can be reduced by 90% after 45 days of storage. The acid value and peroxide value of peanuts were 65% and 40% lower than those in the storage bin without antifungal agent (control) under the same conditions, and the oil yield of peanuts was 20% higher than that of the control.

example 3

[0026] Effect of Vapor Phase Anti-mildew and Fresh-keeping on Cantonese-style Moon Cakes

[0027] The microcapsule essential oil is mixed with anethole 15, cinnamaldehyde 35, citral 40, and salicylaldehyde 10 in parts by weight to prepare a gas-phase slow-release anti-mold antistaling agent for Cantonese moon cake storage, according to 350g / m 3 The dosage of the packaging volume is put into a Cantonese-style moon cake packaging bag and sealed, and stored at a temperature of 30°C and a relative humidity of 80% for 90 days without mildew. The acid value and peroxide value of mooncakes were 58% and 35% lower than those of packaged mooncakes without antifungal agent under the same conditions, respectively.

Abstract

The invention discloses a gas-phase sustained-release mildew-resistant antistaling agent and a preparation method and application thereof. The gas-phase sustained-release mildew-resistant antistaling agent is prepared through complex formulation of microcapsules of four plant essential oils consisting of anethole, cinnaldehyde, citral and salicylaldehyde. Beta-cyclodextrin is used as a wall material to respectively encapsulate the four plant essential oils consisting of anethole, cinnaldehyde, citral and salicylaldehyde, so four plant essential oil microcapsules are obtained; then the four plant essential oil microcapsules are mixed in proportion and then are applied for mildew-resistance and preservation of grains or oil-bearing materials or for mildew-resistance and preservation of raw-food materials and packaged foods. The mildew-resistant antistaling agent inhibits mould through gas-phase fumigating effects of the essential oils and employs microcapsule technology for controlling of volatilization speeds of the essential oils, so a long-acting gas-phase mildew-resistant effect is realized without direct contact between the essential oils with grains, foodstuffs and the like; the mildew-resistant antistaling agent is especially applicable to antibiosis and mildew-resistance of grains, oil-bearing materials and packaged foods under the conditions of high temperature and high humidity, can suppress deterioration of quality of the grains, the oil-bearing materials and the packaged foods, is safe to human beings and livestock and is capable of effectively overcoming the problem of residual of a chemical fumigant.

Description

technical field [0001] The invention relates to the technical field of anti-mildew and fresh-keeping agents, in particular to a gas-phase slow-release anti-mold and fresh-keeping agent and a preparation method thereof. Background technique [0002] At present, the food safety problems caused by mycotoxin contamination of grain, oil and food have attracted more and more people's attention. According to a survey by the World Food and Agriculture Organization, 25% of the world's food is contaminated by confirmed mycotoxins every year. In my country, the mold pollution rate in the four major grain-producing provinces of Shandong, Hubei, Sichuan, and Henan is 75.5%. Mold in grain can produce aflatoxin, zearalenone and other mycotoxins. Mycotoxins can enter our food chain through contaminated grains, feed, and animal foods (milk, meat, eggs) provided by animals fed by these feeds, and exhibit carcinogenicity, genotoxicity, and teratogenicity to humans and animals , can also cau...
