Rice bran nutrition stock solution and its preparation method as well as product usage

Abstract

The invention relates to rice bran nutrient original liquid. The production process includes the following steps: fresh rice bran without impurities is baked, crumbled and screened after stabilization treatment, soaked with purified water till being fluffy, then put into a bain marie with the purified to be gelatinized into rice bran slurry, and then a-amylase with the quality ratio from 0.04 to 0.07 percent is added to perform enzymolysis reaction to the rice bran slurry into rice bran liquid, the impurities are filtered out after the enzyme elimination, and the additive used for making food and beverage or the rice bran nutrient liquid used for making food and beverage can be obtained through high-temperature instant sterilization. The invention has simple and environmentally friendly production process, the operation is convenient, and the loss and destruction of the nutrients can be caused in the production process; the sources of the raw materials are extensive, and the cost is low; the production equipment is simple and reliable, and the equipment investment is little; the produced product is rich in nutrient, and a plurality of nutrient supplementary materials can be matched with the original rice bran nutrient liquid in the production process according to a certain proportion, in order to complement the nutrients, and thereby the nutritional value of the invention is effectively improved.

Description

technical field [0001] The invention relates to food processing, in particular to a rice bran nutrient stock solution, its preparation method and product use.

Problems solved by technology

As the world's largest rice production country, my country is also the country with the most abundant rice bran resources in the world. The annual output of rice bran is more than 10 million tons, which is a renewable resource with a large amount and wide range. However, the in-depth development and application of rice bran and the corresponding theoretical research It is still at a low level, and there are very few commercialized high-value-added rice bran products. Most of these valuable nutrients are wasted as poultry feed and have not been fully developed and utilized.
