Embodiment 1

[0032] The preparation process of the magnesium silicate gel column used in this embodiment is: take 50 parts of quartz sand and put it into the reactor, add 150 parts of NaOH solution with a concentration of 5mol / L, the stirring speed is 100 r / min, and the stirring time is 10min. Add 100 parts of 5mol / L MgCl dropwise 2 solution, the stirring speed is 25r / min, the stirring time is 20min, after fully mixing, the reaction temperature is 130°C for hydrothermal reaction for 6h, after aging, centrifugal separation, discard the supernatant, wash the precipitate with ethanol, and put it under the condition of 110°C After drying, the filter cake was pulverized to obtain magnesium silicate powder; 50 parts of magnesium silicate powder prepared by hydrothermal method, 7 parts of modified montmorillonite powder and 1.0 part of coupling agent were added to 43 parts of Stir and mix the polyvinylidene fluoride solution to form a casting film, let it stand for defoaming for 20 hours, use a s...

Abstract

The invention belongs to the field of grain and oil quality and safety, in particular to a method for removing aflatoxin in vegetable oil by using an ultraviolet-magnesium silicate gel column combineddetoxification method. The vegetable oil is placed in a glassware, the thickness of an oil layer is controlled between 1.5 and 3 cm, the length of an irradiation zone is 0.5 to 1.5 m, the flow rate is 3 to 10 m<2> / h, the plant oil is detoxified by using near-ultraviolet wavelength (UVA wave band, a wavelength is 375-390 nm) excitation fluorescence, and the vegetable oil after ultraviolet excitation fluorescence irradiation is detoxified by a magnesium silicate gel column; the method can effectively remove a variety of aflatoxins in the vegetable oil, the detoxification rate is more than 99.6%, and the impurities and microorganisms in the vegetable oil can also be removed, and the nutrients in the vegetable oil can be well preserved; The equipment is simple, the operation is easy, and thedetoxification effect is stable.

Description

technical field [0001] The invention belongs to the field of grain and oil quality safety, and specifically relates to a method for removing aflatoxin in vegetable oil by using an ultraviolet-magnesium silicate gel column combined with a detoxification method. Background technique [0002] Aflatoxin (Aflatoxin referred to as AFT) is a general term for a class of substances with similar chemical structures. It is a secondary metabolite produced by Aspergillus flavus and Aspergillus parasiticus. The main structure is dihydrofuran ring and oxinone (coumarin) , the former is a toxic substance, and the latter may be related to carcinogenicity. At present, there are more than 20 species whose structures have been determined, including B1, B2, M1, M2, etc. Among them, B1 is the most toxic, its toxicity is 10 times that of potassium cyanide, 68 times that of arsenic, and its carcinogenicity is dimethylnitrosamine 75 times that of carcinogen, which is the strongest chemical carcinog...
