Embodiment 1

[0021] Add 40ul of food additive perillaldehyde to 100g of peanut kernels, mix well in a closed container, put it into an ultrasonic processor for ultrasonic treatment, the ultrasonic frequency is 60kHz, the ultrasonic power is 120W, the ultrasonic temperature is 30°C, and the ultrasonic time is 30min .

[0022] Add 100 g of peanut kernels and 40 ml of 0.2% sodium alginate coating liquid that have been ultrasonically treated with perillaldehyde into a coating machine for coating to obtain coated peanuts, which are stored at room temperature. Preserve the peanuts coated with the method of the present invention and the peanuts not treated with the coating at room temperature (30° C.) for 100 days, the results are shown in figure 2 ,3. From figure 2 and image 3 It can be seen that the number of Aspergillus flavus in the peanuts coated with perillaldehyde-sodium alginate composite film was 10 after being stored at 30°C for 100 days. 3 cfu / g peanut ( figure 2 ), the number...

Embodiment 2

[0024] Add 35ul of food additive perillaldehyde to 100g of peanut kernels, mix well in a closed container, put it into an ultrasonic processor for ultrasonic treatment, the ultrasonic frequency is 70kHz, the ultrasonic power is 110W, the ultrasonic temperature is 40°C, and the ultrasonic time is 40min . Add 100 g of peanut kernels and 60 ml of 0.1% sodium alginate coating liquid that have been ultrasonically treated with perillaldehyde into a coating machine for coating to obtain coated peanuts, which are stored at room temperature. The peanuts coated with the method of the present invention and the peanuts not treated with coatings were stored at room temperature (30°C) for 100 days, and the results are shown in Figure 4 .

[0025] Add 35ul of food additive perillaldehyde to 100g of peanut kernels, mix them evenly in an airtight container, and let them stand for 40min. Add the treated 100g of peanut kernels and 60ml of 0.1% sodium alginate coating solution into the coating ...

Abstract

The invention discloses a method for inhibiting peanut aspergillus flavus pollution by perillaldehyde-sodium alginate composite coating. The method comprises adding a food additive perillaldehyde into peanut kernels, carrying out mixing in an enclosed container to obtain a uniform mixture, putting the mixture into an ultrasonic treatment machine, carrying out ultrasonic treatment so that perillaldehyde fully permeates into the peanut kernels in a gas form, adding the peanut kernels subjected to ultrasonic treatment and a sodium alginate coating liquid into a coating machine, carrying out coating to obtain coated peanut kernels, and carrying out storage at a normal temperature. The method for efficiently inhibiting aspergillus flavus pollution by perillaldehyde-sodium alginate composite coating can realize full immersion of peanut kernels with perillaldehyde, effectively prevents perillaldehyde volatilization, inhibits peanut aspergillus flavus infection, prolongs a preservation period, and is suitable for industrial production.

Description

technical field [0001] The invention relates to a method for inhibiting peanut aflatoxin pollution by a perilla aldehyde-sodium alginate composite coating film, and belongs to the field of food safety and processing. Background technique [0002] Aflatoxin (AFT) is a class of secondary metabolites mainly produced by fungi such as Aspergillus flavus and Aspergillus parasiticus, which are highly carcinogenic and mutagenic. Peanut is one of the most susceptible crops to be infected with Aspergillus flavus, and aflatoxin has a high affinity for peanut. During the storage and transportation of peanuts, because peanuts are rich in nutrients, it is very easy to cause the infection of Aspergillus flavus to multiply, resulting in aflatoxin pollution in peanuts. [0003] At present, the pollution of Aspergillus aflatoxin in peanuts and their products is serious in my country. The investigation found that the phenomenon of aflatoxin B1 (AFB1) exceeding the standard in main grain and o...
