Embodiment

[0029] The invention discloses a method for extracting leucine by using corn gluten powder, which is characterized in that it comprises the following steps: step 1: hydrolysis stage of corn gluten powder; step 2: preparation stage of leucine crude product I; step 3: leucine The crude acid product II preparation stage; step four: the preparation stage of leucine finished product.

[0030] The hydrolysis stage of the corn gluten powder in step 1 is to add hydrochloric acid to the reaction vessel first, then add corn gluten powder, the corn gluten powder and hydrochloric acid described in step 1 are carried out according to the ratio of 1 ton of corn gluten powder: 1.5 cubic meters of hydrochloric acid Feeding. Open the steam valve to heat, the steam pressure is not more than 0.2Mpa, and keep the temperature at 105°C-115°C. After the corn gluten powder is completely dissolved, start to calculate the hydrolysis time, and carry out the heat preservation hydrolysis reaction. The hyd...

Abstract

The invention relates to a method for extracting leucine by utilizing corn protein powder. The method is characterized by comprising the steps of 1, hydrolysis stage of the corn protein powder; 2, preparation stage of leucine crude product I; 3, preparation stage of leucine crude product II; 4 preparation stage of leucine finished product. The method for extracting the leucine by the utilizing corn protein powder takes the corn protein powder as a production raw material, and the corn protein powder is lower in price, so that the production cost is greatly lowered. Furthermore, the product prepared by the method is high in purity, and the production technological conditions are simple, so that the method is more suitable for large-scale production and use.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a method for extracting leucine by using corn gluten powder. Background technique [0002] Leucine is a major biochemical product, widely used in medicine, food and other fields. Leucine is generally used in bread and noodle products; in the preparation of amino acid infusions and comprehensive amino acid preparations, hypoglycemic agents, and plant growth promoters; it can be used as a spice to improve food flavor. In the pharmaceutical industry, L-leucine is an indispensable raw material for clinically selected compound amino acid intravenous injections. It plays an active role in maintaining the nutritional needs of critically ill patients and saving the lives of patients; leucine is also regulating amino acids and proteins. important role in metabolism. Studies have found that leucine is the only amino acid that can regulate protein turnover in skeleta...
