Abstract

The present invention relates to oat deeply processing technology, and is especially technological process of producing oat dietary fiber and nutritious powder with oat bran. The technological process includes microwave enzyme deactivation of oat bran, enzymolysis, centrifugal separation, drying the precipitate and superfine crushing to obtain oat dietary fiber powder, vacuum concentrating the separated supernatant and spray drying to obtain nutritious powder. The present invention extracts the nutritious matters from oat bran effectively, the product has high purity and the production process is environment friendly.

Description

technical field [0001] The invention relates to an oat deep-processing technology, in particular to a technology for producing oat dietary fiber and nutritional powder from oat bran. Background technique [0002] Compared with other grains, oatmeal has comprehensive and high nutritional value. The protein, fat, vitamins, mineral elements, cellulose and other five nutritional indicators all rank first. Now studies have shown that oats contain a lot of dietary fiber. Oat dietary fiber includes two types of dietary fiber, water-soluble and water-insoluble, which are very important for human health. Important physiological functions: (1) Weight loss function; (2) Improve human immunity; (3) Prevent and treat diabetes; (4) Promote colon function and prevent colon cancer; (5) Prevent cardiovascular diseases And therapeutic effect, widely used in food industry. Oat grains are rich in protein, which can reach 13% to 20% due to different varieties, ranking first among grains. The p...
