基于混料设计优化膳食纤维补充剂配方及其功能特性研究OA

A D-optimal mixture design was employed to investigate the effects of different proportions of dietary fiber supplements,with rice bran dietary fiber as the main component,supplemented by psyllium husk powder and fructooligosaccharides,on their water-holding capacity(WHC),swelling water capacity(SWC),oil-holding capacity(OHC),and sensory evaluation.The results showed that the optimal ratio of the rice bran dietary fiber supplement was as follows:rice bran dietary fiber 64.1%,psyllium husk powder 18.7%,and fructooligosaccharides 17.2%.Under this condition,the WHC of the supplement was 12.50±0.12 g·g-1,the SWC was 14.29±0.34 mL·g-1,the OHC was 2.86±0.06 g·g-1,and the sensory score was 81.0±2.5 points.Due to its excellent functional properties,rice bran dietary fiber could be widely applied in the development of dietary supplement products.Moreover,the interaction among rice bran dietary fiber,psyllium husk powder,and fructooligosaccharides had a significant impact(P<0.05)on the WHC,SWC,OHC,and sensory scores.The development of rice bran dietary fiber supplements could realize the high-value utilization of rice bran by-products and promote the development of circular economy.
