Abstract
Yellow millet rice bran is a byproduct of of yellow millet. It is rich in dietary fiber, which is called the seventh nutrients following the sugar, protein, fat, vitamins, minerals and water. It has strong oil and water holding capacity , and can increase the solubility and induced the microbial action, prevent and assist treatment of many diseases. Yellow millet rice bran was used as the raw material to extract water - soluble dietary fiber. The optimal extraction processing parameters were explored by single - factor and orthogonal experiments through the evaluation of the effects of material - liquid ratio, extraction pH, extraction temperature and extraction time on the extraction rate. Results indicated that the optimal extraction processing parameters for water - soluble dietary fiber were material - liquid ratio of 1 : 17mL/g, pH 5. 0, extraction temperature of 95℃ and extraction time of 70 min. The extraction rate of water - soluble dietary fiber was up to 14. 76% . The water - holding capacity and swelling power of the dietary fiber were 7. 4g/g and 6. 25mL/g, respectively.关键词
