Problems solved by technology

Since rice is an important way for people to obtain nutrition, long-term consumption of polished white rice lacking dietary fiber may easily lead to a lack of certain nutrients without sufficient nutritional supplements. Insufficient two causes nutritional deficiencies and causes various diseases such as "disease of civilization" and "disease of wealth", thus affecting people's health
This kind of fortified rice has little nutrient loss during storage, transportation and sales, but the production process has high energy consumption, large investment, and high production cost, so it is not suitable for rice processing enterprises in my country.
In addition, the nutrient-enhanced rice prepared by the existing technology has average cooking quality and poor taste, so it is difficult to be accepted by consumers.

Abstract

The invention discloses a method for preparing high-dietary-fiber nutrient enrichment rice. The method comprises the following steps: (1) preparing rice bran dietary fiber; and (2) remixing the rice bran dietary fiber with the rice meal by adopting a single-screw extrusion technology, thus obtaining the high-dietary-fiber nutrient enrichment rice with better cooking quality. Obesity, diabetes, hypertension, hyperlipidemia and other cardiovascular diseases can be prevented after the high-dietary-fiber nutrient enrichment rice is eaten for a long time; and the high-dietary-fiber nutrient enrichment rice is very beneficial to the health of customers.

Description

technical field [0001] The invention relates to a method for preparing high-dietary-fiber nutrient-enhanced rice, in particular to a method for preparing high-dietary-fiber nutrient-enhanced rice by using screw extrusion technology, which belongs to the technical field of food processing. Background technique [0002] As a major food crop, rice is widely planted around the world and is a very important source of food for human beings. According to the statistics of the Food and Agriculture Organization of the United Nations, there are 122 countries in the world that grow rice, and the annual planting area reaches 140-157 million hectares, accounting for about 23% of the grain planting area; the total output of rice is about 600 million tons, accounting for about 29% of the total grain output ; There are more than 50 countries with an annual output of more than 100,000 tons of rice. Among the top ten rice producing countries in the world, all are in Asia except Brazil, with ...
