Embodiment 1

[0052] Step 1: Obtain the waste starch residue after wheat gluten (gluten) and wheat starch are obtained by dry process of wheat grain, and carry out saccharification and enzymatic hydrolysis on the waste starch residue of wheat flour, add Saccharomyces cerevisiae for fermentation treatment, and ferment into ethanol Finally, the ethanol is distilled and extracted, and the remaining fermentation concentrate is the original liquor of wheat distiller's grains.

[0053] Step 2, adding the first enzyme preparation with a mass fraction of 0.5% to the wheat distiller's grains stock solution, and performing the first enzymolysis under the operating conditions of pH value 7.5, enzymolysis temperature 20°C, and enzymolysis reaction time 8 hours Degrade toxins to remove biotoxins from wheat distiller's grains. Among them, the first enzyme preparation is a bacterial enzyme mixture preparation of Bacillus and detoxification enzyme, aflatoxin decomposing enzyme and facultative bifidobacteri...

Embodiment 2

[0065] Step 1: Obtain the waste starch residue after wheat gluten (gluten) and wheat starch are obtained by dry process of wheat grain, and carry out saccharification and enzymatic hydrolysis on the waste starch residue of wheat flour, add Saccharomyces cerevisiae for fermentation treatment, and ferment into ethanol Finally, the ethanol is distilled and extracted, and the remaining fermentation concentrate is the original liquor of wheat distiller's grains.

[0066] Step 2, add the first enzyme preparation with a mass fraction of 0.6% to the wheat distiller's grains stock solution, and perform the first enzymolysis under the operating conditions of pH value 3, enzymolysis temperature 50°C, and enzymolysis reaction time 2 hours Degrade toxins to remove biotoxins from wheat distiller's grains. Among them, the first enzyme preparation is a bacterial enzyme mixture preparation of Bacillus and detoxification enzyme, aflatoxin decomposing enzyme and facultative bifidobacteria, and a...

Abstract

The invention discloses a resource utilization method of wheat distiller's grains. The resource utilization method of wheat distiller's grains comprises the following steps: performing saccharification and enzymolysis of wheat flour, adding Saccharomyces cerevisiae for fermentation, distilling and extracting ethanol to obtain wheat distiller's grains stock solution; The first enzyme preparation is added to the wheat distiller's grains stock solution to perform the first enzymatic hydrolysis to degrade the toxin, so as to remove the biotoxin in the wheat distiller's grains stock solution to obtain the enzymatic hydrolysis of distiller's grains. The technical scheme of the invention can effectively remove the biological toxins therein, so that the by-products obtained from the subsequent resource utilization can meet the national hygienic standard.

Description

technical field [0001] The invention relates to the technical field of wheat distiller's grains, in particular to a resource utilization method of wheat distiller's grains. Background technique [0002] Wheat distiller's grains are usually a by-product of ethanol production by fermentation, and its main components are polysaccharides, proteins, and organic acids. In order to fully reuse resources to avoid waste of resources, people usually make in-depth resource utilization of distiller's grains to obtain various by-products. However, because distiller's grains contain a large amount of biotoxins, if they are not removed, the final by-products cannot meet the national health standards due to biotoxins, and need further treatment before use. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose...
