Embodiment 1

[0023] A method for removing vomitoxin in corn germ, the specific process is as follows:

[0024] (1) 500kg of corn germ is cleaned up, and stones and sundries in the corn germ are removed;

[0025] (2) Spray ethanol-water / sodium hydroxide solution (ethanol 4kg, water 88kg, sodium hydroxide 1.5kg, sodium hydroxide concentration is 0.4mol / L) in the corn germ after cleaning, stir corn germ while spraying solution , so that the corn germ absorbs the liquid and swells evenly, and the moisture content of the swollen corn germ is 14.5%;

[0026] (3) carrying out flaking treatment with the corn germ processed in step (2);

[0027] (4) Carry out embryo frying treatment to the corn germ after flaking, temperature 115 ℃;

[0028] (5) Detect the water content of the germ, and the water content is 8.8%, and the temperature is lowered to room temperature, and the oil pressing process is carried out to obtain crude oil.

Embodiment 2

[0030] A method for removing vomitoxin in corn germ, the specific process is as follows:

[0031] (1) 500kg of corn germ is cleaned up, and stones and sundries in the corn germ are removed;

[0032] (2) Spray ethanol-water / sodium hydroxide solution (4kg of ethanol, 88kg of water, 1.8 parts of sodium hydroxide, and the concentration of sodium hydroxide is 0.5mol / L) in the cleaned corn germ, stir the corn germ while spraying the solution , so that the corn germ absorbs the liquid and swells evenly, and the moisture content of the swollen corn germ is 14.1%;

[0033] (3) carrying out flaking treatment with the corn germ processed in step (2);

[0034] (4) Carry out embryo frying treatment to the corn germ after flaking, temperature 115 ℃;

[0035] (5) Detect the water content of the germ. The water content is 8.1%, and the temperature is lowered to room temperature, and the oil extraction process is carried out to obtain crude oil.

Embodiment 3

[0037] A method for removing vomitoxin in corn germ, the specific process is as follows:

[0038] (1) 500kg of corn germ is cleaned up, and stones and sundries in the corn germ are removed;

[0039] (2) Spray ethanol-water / sodium hydroxide solution (5 kg of ethanol, 88 kg of water, 2.2 kg of sodium hydroxide, and a concentration of sodium hydroxide of 0.6 mol / L) in the cleaned corn germ, stir the corn germ while spraying the solution , so that the corn germ absorbs the liquid and swells evenly, and the moisture content of the swollen corn germ is 15.0%;

[0040] (3) carrying out flaking treatment with the corn germ processed in step (2);

[0041] (4) Carry out embryo frying treatment to the corn germ after flaking, temperature 115 ℃;

[0042] (5) Detect the moisture content of the germ, the moisture detection value is 6.5%, drop to room temperature, carry out the oil pressing process, and obtain crude oil.

Abstract

The invention relates to a method for removing vomitoxin from corn germs, and belongs to the technical field of corn germ oil. The method for removing vomitoxin from corn germs comprises the following steps: firstly, cleaning the corn germs, and then adding an ethanol-water alkaline solution for swelling; crushing the swelled corn germs, after crushing, stir-frying the germs, and after the water content in the germs is reduced to 9% or below, conducting oil squeezing treatment. According to the method, the corn germs are treated by using the ethanol and the alkaline substance, so that the content of vomitoxin in the treated corn germs is greatly reduced; and in the subsequent treatment process, the embryo is stir-fried at high temperature, so that the residual vomitoxin can be removed. The content of vomitoxin in the finally obtained corn germ can be reduced to below the national standard.

Description

technical field [0001] The invention belongs to the technical field of corn germ oil, in particular to a method for removing vomitoxin from corn germ. Background technique [0002] Vomitoxin (vomitoxin), chemical name: deoxynivalenol (DON), belongs to the trichothecene compound, which is produced by Fusarium graminearum (F. graminearum) and yellow Fusarium (F. culmorum), etc. Produced, the content is higher in grains such as wheat, barley, oats, and corn. Can affect the digestive system, with cytotoxicity, immunotoxicity, neurotoxicity, etc. DON can combine with the peptidyltransferase active center of ribosomal 60s subunit to trigger ribosomal stress response, inhibit the synthesis of DNA, RNA and protein, induce apoptosis, etc., causing damage to the intestinal tract and immune system, and has Genotoxicity has a serious impact on the health of humans and animals, and is a mycotoxin with the highest detection rate and exceeding standard rate in human and animal food.
