Embodiment 1

[0032] The device that uses UV and electron beams to synergistically degrade peanut aflatoxin processes materials step by step. The specific steps are as follows:

[0033] Step 1: Collect peanuts, wash them, adjust the moisture content of peanuts to 8%, the temperature is 25°C, and the material thickness is 20mm;

[0034] Step 2. Set the UV and electron beam processing parameters. The UV lamp is fixed above the inner cavity of the irradiation chamber, and the 254nm and 365nm UV lamps are set to be turned on at the same time, and the irradiation intensity is 600μW / cm 2 , 80kGy is selected for the electron beam acceleration field irradiation measurement, and the electron beam irradiation field covers the entire irradiation chamber;

[0035] Step 3, Determination of the initial concentration of peanut aflatoxin C 0 Be 518 μ g / kg, measure 1min, 2min, the aflatoxin content after 4min three processing times, substitute into degradation formula ln(C t / C 0 )=A+B*t, A is calculated...

Embodiment 2

[0048] refer to figure 1 For the second embodiment of the present invention, in this embodiment, the UV and electron beam synergistic degradation device of peanut aflatoxin mentioned in the embodiment 1 involved in the present invention is as figure 1 As shown, it includes a conveyor belt speed regulating device 100, a conveyor belt M, a steam moisture regulating device 200, a blowing device 300 and a radiation chamber 400. In the present invention, the conveyer belt speed adjusting device 100 is used to adjust the conveying speed of the conveyer belt, and the conveyer belt M is used for directly conveying peanuts. The steam moisture regulating device 200 is used for regulating the moisture and temperature of the washed peanuts. The blowing device 300 is used for. The radiation chamber 400 is used for irradiation of ultraviolet rays and action of electron beams.

Embodiment 3

[0050] refer to figure 1 , 2 It is the second embodiment of the present invention. In this embodiment, the device involved in the present invention is as figure 2 As shown, a self-locking member 500 is included.

[0051] Specifically, such as figure 1 As shown, there is a switch door N outside the control box of the steam moisture regulating device 200, and a self-locking part 500 exists on the switch door N. Used to lock the closed door N. Such as figure 2 As shown, its structure includes a driving rod 501 , a driven rod 502 , a dowel rod 503 and a base member 504 . And the two are connected by a hinge 505 . Wherein, the active rod 501 is connected with the base member 504 by the first hinge 505a-1, the active rod 501 is connected with the dowel rod 503 by the second hinge 505a-2, and the driven rod 502 and the dowel rod 503 are connected by the third hinge 505a. -3 connection, the driven rod 502 is connected to the base member 504 with hinge four 505a-4. The overal...

Abstract

The invention discloses a method for degrading aflatoxin of peanuts. The method comprises the following steps of cleaning peanut granules, and regulating the moisture content of the peanut granules and the temperature of the peanut granules; regulating the piling thickness of peanut granule materials to be treated, and coprocessing the peanut granule materials through ultraviolet rays and electronbeams. According to the method disclosed by the invention, the ultraviolet rays and the electron beams are in synergy, and inside and outside detoxification is performed at the same time, so that thedegradation rate of the aflatoxin is obviously increased, the equipment is convenient to operate, and the method is suitable for processing reality of enterprises.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for degrading peanut aflatoxin. Background technique [0002] Aflatoxin, referred to as AFT, is a secondary metabolite of fungi such as Aspergillus flavus and Aspergillus parasiticus. It was discovered in the "Turkey Incident" in London, England in 1960 and attracted attention. Among the known mycotoxins, aflatoxin is the most toxic one. Animal experiments show severe acute toxicity and obvious chronic toxicity, among which aflatoxin B is the most toxic. 1 (AFB 1 , chemical formula C 17 h 12 o 6 , molecular weight 312) is particularly violent, and is listed as a "first-class carcinogen" by the World Health Organization (WHO) Cancer Research Institute. The main target organ of aflatoxin is the liver, causing liver damage, hepatitis, cirrhosis, and liver necrosis. All countries in the world attach great importance to the pollution control of aflat...
