Problems solved by technology

[0004] At present, studies have shown that cinnamon essential oil, litsea cubeba oil, eugenol and other essential oils can inhibit the growth of Aspergillus flavus. However, a single essential oil has poor inhibitory effect on Aspergillus flavus. Application in long-term storage of agricultural products or crops

Embodiment 1

[0026] 1. Preparation of bacteria-containing plates

[0027] On the ultra-clean workbench, use a pipette gun to pipette the activated Aspergillus flavus liquid (the specific concentration is about 10 7 CFU / mL) 100 μL, inoculated in Zapei's medium, spread evenly to make a bacteria-containing plate; paste a sterilized filter paper (d=6mm) on the center of the bacteria-containing plate cover.

[0028] 2. Determination of the minimum inhibitory concentration of plant essential oils when used alone

[0029] Dilute cinnamon essential oil, fennel essential oil and oregano oil with Tween-80, draw 0.2 mL of each dilution solution under sterile conditions, add it to the filter paper in the center of the plate plate containing bacteria, seal it with a sealing tape, and incubate it upside down. Make the essential oil concentration in the air in the petri dish reach 5-150mg / L air series concentration respectively, incubate at 28°C for 5 days, take the lowest concentration of the sample th...

Abstract

The invention discloses an antimildew agent and an antimildew method for peanuts, and belongs to the technical field of antimildew agents for crops. The antimildew agent is prepared from mixing composite plant essential oil, a solvent and a stabilizer according to the weight ratio being 75 to 88:9 to 20:3 to 5; the composite plant essential oil is prepared from cinnamon essential oil, fennel essential oil and origanum oil according to the weight ratio being 10 to 20:10 to 30:10 to 30. According to the antimildew agent provided by the invention, the composite essential oil prepared by mixing the cinnamon essential oil, the fennel essential oil and the origanum oil according to the weight ratio being 20:10:10 has a synergistic effect on inhibiting the growth of aspergillus flavus; the antimildew agent prepared from the composite essential oil, the solvent and the stabilizer can be used for preventing mold contamination during the peanut storage process; and according to the antimildew agent, the content of aflatoxin in peanut storage can be remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of antifungal agents for crops, and in particular relates to an antifungal agent for peanuts and an antimold method thereof. Background technique [0002] Aflatoxins are the most toxic and carcinogenic natural pollutants found today. It not only causes great harm to human and animal health, but also brings huge economic losses. Aflatoxin not only pollutes food crops such as corn and rice, but also pollutes peanuts, milk, and cooking oil. [0003] Plant essential oil is a kind of secondary metabolites in plants. It is a naturally occurring active substance and will not pose a threat to the environment. At present, many studies have proved that plant essential oils have various functions such as antibacterial, anti-inflammatory, anti-oxidation, and anti-aging. It has been widely used in the fields of medical care, food industry and daily chemical products. [0004] At present, studies have shown that cinna...
