Embodiment 1

[0022] Embodiment 1 removes zearalenone toxin in corn germ oil

[0023] Experiment purpose: In this experiment, corn (zearalenone content is 15μg / kg, 53μg / kg, 208μg / kg) was used as the raw material for the preparation of corn germ oil, and the national standard (GB / T23503-2009 zearalenone in food Determination of Immunoaffinity Chromatography Purification High Performance Liquid Chromatography) Determination of the content of zearalenone in corn germ and corn germ oil.

[0024] Experimental instruments and reagents: high performance liquid chromatography, water bath, pH meter, constant temperature shaking incubator. Methanol (chromatographically pure), acetonitrile, pure water.

[0025] Experimental steps:

[0026] Divided into three groups of experiments, No. 1 corn, No. 2 corn and No. 3 corn, No. 1 corn had zearalenone content of 15 μg / kg, No. 2 corn had zearalenone content of 53 μg / kg, No. The content of zearalenone in corn is 208 μg / kg. The experimental procedures are d...

Abstract

The invention discloses a method for industrially removing zearalenone out of maize germ. According to the method, in a process of industrially producing the maize germ, the pH value of crude oil is adjusted to 9-10 by utilizing alkali in an alkali refining deacidification step of a crude oil refining technique so that zearalenone is effectively removed, and thus the maize germ with the zearalenone content being below 60 microgram / kilogram is obtained. According to the method for industrially removing zearalenone out of the maize germ disclosed by the invention, the zearalenone toxin can be effectively removed, the problem that zearalenone in the industrially produced maize germ is out of the standard is solved, and the food safety of grain and oil is finally ensured.

Description

technical field [0001] The invention relates to a method for industrially removing zearalenone from corn germ oil. Background technique [0002] Corn is a traditional bulk agricultural product in my country, and its production, consumption and export volume account for a considerable proportion in the world. During the production and storage of corn, due to improper production methods and environmental conditions, molds are polluted and multiplied in corn. The existence of a large number of molds in corn has seriously affected the quality of corn, and at the same time, various mycotoxins produced by molds have brought direct and potential harm to human health. [0003] Zearalenone (ZEN for short) mainly exists in moldy corn. ZEN is an estrogenic mycotoxin produced by Fusarium spp. (mainly the fungus Fusarium graminearum) that grows in a humid environment. ZEN has an estrogen-like effect, has strong reproductive toxicity and carcinogenic effect, can cause acute and chronic ...
