Embodiment 1

[0024] Embodiment 1, reduce the aflatoxin B in the contaminated peanut 1 Methods

[0025] 1. Aflatoxin B in contaminated peanuts 1 Determination of detection method

[0026] Aflatoxin B has been reported 1 Most of the detection methods are high-performance liquid chromatography-fluorescence detector detection methods, there are many interference factors, and the derivation is easy to cause experimental errors. In this experiment, high-performance liquid chromatography-tandem mass spectrometry (ie, HPLC-MS / MS detection) was used to determine aflatoxin B1, and the validity of the method was verified by methodology.

[0027] 1) Selection of qualitative and quantitative determination instruments and conditions: In this experiment, dual detection of chromatography (retention time qualitative) and mass spectrometry (characteristic ion of the substance to be tested) was selected (ie HPLC-MS / MS detection), which can completely eliminate interference and ensure accurate qualitative ...

Abstract

The invention discloses a method for degrading aflatoxin, which uses electron beams to radiate a sample containing the aflatoxin to obtain the sample with reduced aflatoxin content. The method can directly radiate finished products such as agricultural products, food, and feed, has simple operation and obvious effects, and makes the degradation rate of aflatoxin B1 reach 71.51 percent.

Description

technical field [0001] The invention relates to a method for degrading aflatoxin. Background technique [0002] Aflatoxin (AF) is one of the most harmful mycotoxins to humans and animals. A large number of data confirm that aflatoxin has a strong toxic effect on the liver tissue of humans and animals, and can lead to liver cancer and even death in severe cases. Aflatoxin contamination of food is relatively serious, especially the most serious and common contamination of peanuts, walnuts, corn and their products. In addition, aflatoxins are often found in foods such as soybeans, rice, macaroni, milk and its products, and edible oils. Aflatoxin not only reduces the quality of agricultural products and feed, causing huge economic losses, but also can enter the human body through animal-derived foods such as meat and milk that are contaminated or contain aflatoxin, posing a threat to human health. The most toxic of these is aflatoxin B 1 (C 17 h 12 o 6 , molecular weight ...
