Method for preparing high-nutrition rice bran with enzymatic method

Abstract

The invention discloses a method for preparing high-nutrition rice bran with an enzymatic method, belonging to the technical field of agricultural product processing. In the method for preparing the high-nutrition rice bran with an enzymatic method, total components of stable rice bran or fresh rice bran which are used as raw materials are processed with cellulase, protease and phytase together, and the prepared high-nutrition rice bran has good taste, high nutrient value and high utilization. The method is easy and convenient to operate, has mild reacting condition and no pollution, and well reserves the effective nutrient components of the rice bran. The method for comprehensively utilizing the total components of the rice bran has the effects of stabilizing and sterilizing the fresh rice bran, so that the effective components can be efficiently released, nutrient factors can be inhibited, functional components can be improved, phytate can be converted into inositol and phosphor phosphate to better play the role of health-care, and the value of the rice bran serving as high-quality health-care products can be realized.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and in particular relates to a method for preparing high-nutrition rice bran through combined action of cellulase, protease and phytase on rice bran. Background technique [0002] my country is the world's largest rice-producing country, with an annual output of about 198 million tons, accounting for 1 / 3 of the world's total output. Rice resources are very rich. Brown rice as paddy ( Oryza stativa L.) A form after the caryopsis is removed. Compared with white rice, in addition to endosperm, it also has tissue structures such as pericarp, seed coat, aleurone layer and embryo, and has vitality; brown rice contains more than white rice. Nutrients and physiologically active ingredients. A large amount of important nutrients in brown rice are concentrated in rice bran, which contains 12% to 16% protein, 12% to 23% fat, 8% to 10% crude fiber and 7% to 12% ash. In addition, it ...

Problems solved by technology

At present, in China, except for 10% to 15% of rice bran is used to make rice bran oil or extract calcium phytate, inositol and oryzanol, most of them are used as feed for livestock and poultry. In addition, some research and small-scale production involve a single The preparation and separation of active ingredients, resulting in more waste and increased costs for subsequent processing
