Embodiment 1

[0039] Direct enzymatic hydrolysis: Take 10kg of highland barley bran through a 40-mesh sieve, add water to adjust the water content to 30%, heat it under 600w microwave power for 2 minutes to stabilize it, add the stabilized highland barley bran to 40kg of distilled water to prepare a suspension, and adjust pH=8.5 , adding 0.25 kg of alkaline protease, stirring evenly, and enzymatically hydrolyzing in a water bath at 50°C for 1.5 hours, cooling to obtain a suspension of enzymatically hydrolyzed highland barley bran.

Embodiment 2

[0041]Direct enzymatic hydrolysis: Take 15kg of highland barley bran through a 40-mesh sieve, add appropriate amount of water to adjust the moisture content to 20%-30%, and heat it under 800w microwave power for a certain period of time for 8 minutes to stabilize it. Add stabilized barley bran to 30kg of distilled water to prepare a suspension pH 6.5, add 0.45kg of neutral protease (suspension: enzyme = 1% v / wt), stir evenly, oscillate enzymolysis in a water bath at 50°C for 1 hour, and cool to obtain Enzymatic hydrolysis of highland barley bran suspension.

Embodiment 3

[0043] Direct enzymatic hydrolysis: Take 10kg of highland barley bran through a 40-mesh sieve, add water to adjust the moisture content to 20%-30%, and heat it under 650w microwave power for a certain period of time for 4min to stabilize it. Add the stabilized barley bran to 60kg of distilled water to make a suspension pH 4.5, add 1.05kg of cellulase and neutral protease at a ratio of 1:2, stir evenly, oscillate in a water bath at 50°C for 3 hours, and cool to obtain the enzymatic hydrolyzed barley bran suspension.

Abstract

The present invention relates to a method for preparing highland barley bran oil from highland barley bran, specifically to a method for preparing highland barley bran oil from highland barley bran using a water-enzyme method, pertaining to the field of grain and oil deep processing technique. The method includes: firstly performing enzymolysis to the highland barley bran, and then adopting a three-phase separation extraction method, solvent extraction or cold demulsification extraction method to extract highland barley bran oil, wherein, the enzymolysis to the highland barley bran is divided into a method of performing direct enzymolysis to the highland barley bran or a method of firstly alkali extraction and then performing enzymolysis enzymolysis barley bran. The inventive water-enzyme method has a environmental-protecting type extraction process and good safety; in addition, the enzymolysis condition is mild, and can achieve the object of simultaneously using the lipid and protein, and the oil has not been processed under high temperature, thereby improving the quality of the extracted lipid; the invention has improved oil yield; the lipid obtained by the water-enzyme method does not require the degumming process, thereby simplifying the lipid refining process. Therefore, the inventive method has stronger industrialization practicability and operability.

Description

technical field [0001] The invention relates to a method for preparing highland barley bran oil from highland barley bran, in particular to a method for preparing highland barley bran oil from highland barley bran by using an aqueous enzymatic method, and belongs to the technical field of grain and oil deep processing. Background technique [0002] Highland barley (Hordeum Vulgare L. varnudum Hook. f) belongs to one of the barley varieties of the genus Hordeum in the family of Gramineae in plant classification. Highland barley is the most important food crop on the Qinghai-Tibet Plateau. However, due to backward processing technology and poor taste of the product, although it has played an important role in solving the food and clothing problems of local farmers and herdsmen, the development of deep processing and comprehensive utilization of highland barley agricultural products will improve its quality. Added value is more imminent. Highland barley bran is the main proces...
