Problems solved by technology

[0004] Physical adsorption method: At present, many studies have shown that montmorillonite, activated carbon, clinoptilolite, cholestyramine, etc. have certain adsorption capacity for mycotoxins, but these adsorbents generally have low adsorption efficiency and no selectivity; such as CN104961718B Disclosed is a special equipment and removal method for trace harmful impurity zearalenone in natural vitamin E. The method is to first extract the natural vitamin E-petroleum ether solution through methanol-water solution and then use montmorillonite or activated carbon as adsorbent for adsorption
In this method, the adsorption of montmorillonite and activated carbon has no selectivity, which will reduce the yield of vitamin E, and the treatment of 30 tons of vitamin E requires parking to replace the adsorbent, which has low efficiency and high operating costs
[0005] Chemical method: Generally, chemical drugs are used to degrade the structure of zearalenone, such as acid, alkali, oxidant, etc., but adding these chemical reagents will cause certain damage to nutrients such as grain, feed or other foods, and may cause New toxic compounds, so the method is generally less used in the food sector

Embodiment 1

[0109] Embodiment 1: remove zearalenone from natural vitamin E

[0110] The implementation steps of this embodiment are as follows:

[0111] A. Iminodiacetic acid type chelating resin pretreatment

[0112] Under the room temperature of temperature 26 ℃, according to the ratio of the imine diacetic acid type chelating resin in grams and the deionized water in milliliters is 1:8, let the imine diacetic acid type chelating resin sold by Mitsubishi Chemical Corporation under the trade name DIAION CR-11 be 1:8. Amine diacetic acid type chelating resin soaks 3.6 hours in pH 8 deionized waters, makes this chelating resin fully swell, then is 3.0 according to the ratio of iminodiacetic acid type chelating resin in grams and milliliter saturated sulfate solution , allowing the fully swollen chelating resin to be soaked in saturated sodium sulfate solution for 0.8 hours, followed by washing with deionized water according to the ratio of soaking chelating resin in grams to deionized wat...

Abstract

The invention relates to a method for removing zearalenone from natural vitamin E and a pure vitamin E product obtained by the method. The method for removing zearalenone comprises the steps of pretreatment with iminodiacetic acid type chelating resin, column packing, adsorption, washing, separation and the like. The process of the method for removing zearalenone in the present invention is simple, does not introduce other substances, does not require other separation steps, and does not cause secondary pollution to vitamin E products; compared with adsorbents such as diatomite montmorillonite, the adsorption The efficiency is about 80-90% high, and the material loss is small.

Description

【Technical field】 [0001] The invention belongs to the technical field of food. More specifically, the present invention relates to a method for removing zearalenone from natural vitamin E, and also relates to a pure vitamin E product obtained by the method. 【Background technique】 [0002] Zearalenone (Zearalenone, ZEN), also known as F-2 virus, is a kind of lactone compound of 2,4-dihydroxybenzoic acid, which is a species of Fusarium (including Fusarium graminearum, Fusarium three-line, Horsetail Fusarium, Fusarium oxysporum and Fusarium moniliforme, etc.) secondary metabolites. Zearalenone has attracted much attention due to its frequent occurrence and high estrogenic activity in cereals worldwide. In addition to significant estrogenic effects, zearalenone exhibits immunotoxicity, genotoxicity, reproductive toxicity, and carcinogenicity. Corn is the grain most susceptible to zearalenone contamination. [0003] Natural vitamin E products are derived from the deodorized d...
