Problems solved by technology

However, the above studies did not involve the water absorption characteristics of brown rice under natural soil conditions. Therefore, further research is still needed to optimize the process based on the germination law of brown rice under natural conditions.

Embodiment Construction

[0016] (1) Pre-germination treatment of brown rice: remove impurities, broken grains, no germ grains, mildewed grains and heterochromatic grains from the raw brown rice, and then sterilize it with ultraviolet light for 10-15 minutes, measure the moisture content of the raw material to 12%, weigh 10 kg for use .

[0017] (2) brown rice moisture adjustment: the brown rice raw material after step (1) is processed is placed under room temperature condition, and in this example, brown rice raw material quality is 10kg, and initial moisture content is 12%, and material moisture quality is 1.2kg in the initial stage. Through real-time monitoring of the flow rate of the water adding nozzle and the moisture content of the brown rice material, before the moisture content of the material is 18%, the hourly increase rate of the moisture content is selected to be 1.0% / h on average, and the formula: the mass of water to be added = (target moisture content × initial moisture content of the ma...

Abstract

The invention belongs to the technical field of further processing of grain, and in particular relates to a process for optimizing the production of germinated brown rice. The process is characterized in that the engineering method is used to simulate according to the natural germinating process of rice in a soil environment condition, the high germination rate and high gamma-aminobutyric acid content in germinated brown rice are the targets, and on that basis, the optimization process parameter combination meeting the demands on water absorption, temperature, ventilation and other conditions for germination of brown rice are obtained. Compared with the traditional brown rice germination process, the process, provided by the invention, has the advantages that the link of soaking is avoided, so that the natural germination rules of brown rice are met, no sewage is produced, the loss on dissolution of nutritional substances of the brown rice in soaking is avoided, and the energy consumption for drying of the germinated brown rice due to excessive water sucking in the soaking link can also be decreased. With the adoption of the process for optimizing, the germination rate of brown rice can be increased by 5 to 7%, and the gamma-aminobutyric acid content in germinated brown rice can be increased by about 2.4 times.

Description

technical field [0001] The invention relates to a new production process of germinated brown rice, mainly relating to the humidification method before brown rice germination, aiming at reducing the crack rate during brown rice germination, increasing the germination rate of brown rice and the content of nutrient substance γ-aminobutyric acid, reducing energy consumption and avoiding sewage Emissions belong to the technical field of grain deep processing. Background technique [0002] my country is the largest rice production and consumption country in the world. With the improvement of people's living standards and changes in consumption concepts, people have higher and higher requirements for the nutritional value and health care functions of rice. About 60% of the nutrients in rice are accumulated in the bran layer and germ, which account for about 10% of the weight of rice, so traditional rice processing methods have caused a great waste of nutrients. Although the nutrit...
