Embodiment 1

[0027] Example 1 Preparation of acidic electrogenerated functional water

[0028] A. Preparation of strongly acidic electrogenerated functional water:

[0029] (1) Sodium chloride is dissolved in drinking water at a ratio of 0.2% by weight, fully stirred evenly, and then placed in figure 1 In the two electrolyzers of the strong acidic electric functional water generator shown;

[0030] (2) When the voltage is 30V, the current is 2.0A, the electrode distance is 12mm, and the plate area is 108cm 2 The electrolysis reaction was carried out for 15 minutes; that is, strong acid electrogenerated functional water was obtained in the anode electrolyzer, and alkaline electrogenerated functional water was obtained in the cathode electrolyzer. Strongly acidic electro-generated functional water is pH=2.50±0.77, ORP=1097±28mV, and the content of available chlorine is 100.5±3.9mg / L; the obtained alkaline electro-generated functional water is pH=11.46±0.11, ORP=-851.8± 45.3mV.

Abstract

The invention discloses a method for clearing away aflatoxin from crop seeds by utilizing acid electrolyzed functional water, and belongs to the field of oil and grain product safety process technology. The method comprises the following steps: mixing strong acid electrolyzed functional water or weak acid electrolyzed functional water and the crop seeds polluted by the aflatoxin in a mass ratio of 1:1-10:1; and at the temperature of between 25 and 65DEG C, oscillating for 5 to 60 minutes, dripping water to dryness, and baking or airing the crop seeds. The acid electrolyzed functional water plays a role in clearing away the toxin from the crop seeds, and secondary pollution and toxin residue caused by elution are avoided; and for the crop seeds after the treatment, skins are not broken, the appearance is not changed basically, main quality indexes such as water content, fat content and protein content are not changed basically, and the crop seeds can be further processed. The method is simple and has low treatment cost; and the used electrolyzed functional water is safe and nontoxic, and has no residue or potential safety hazard. The aflatoxin clearing rate is over 90 percent.

Description

technical field [0001] The invention relates to the technical field of grain, oil and food safety technology, in particular to a method for removing aflatoxin from crop grains by using acidic electro-generated functional water. Background technique [0002] "Electrolyzed Functional Water (EFW)", also known as electrolyzed ionized water, oxidation potential water and electrolyzed water. It is a general term for the acidic electrogenic functional water and alkaline electrogenic functional water obtained by the dilute solution of chlorine-containing compounds and drinking water or hydrochloric acid and drinking water under the treatment of a special electrolysis device. Among them, the acidic electrogenerated functional water has a lower pH value, a higher oxidation-reduction potential (Oxidation-Reduction Potential, ORP) and a certain amount of available chlorine content (Available Chlorine Concentration, ACC). It mainly includes: strong acidic electrogenic functional water (...
