Abstract:

In order to develop a dietary fiber-rich compound rice by squeezing, broken brown rice, chickpea and oats were used as raw materials, the extrusion process conditions were optimized by single-factor experiments and the response surface experiment with the comprehensive score as an indicator. It was shown that the optimal process parameters were as follow: screw speed of 160 r·min-1, extrusion temperature of 140 ℃, moisture content of 33%, chickpea addition amount of 16%, oat addition amount of 19%, broken brown rice addition amount of 65%. Under the optimal conditions, the comprehensive score and the sensory score of the compound rice were 75.96±0.50 and 92.85±2.11, respectively, and the content of dietary fiber was 12.65%, the soluble dietary fiber content was 6.93%, which was in accordance with the high dietary fiber standard of national standard GB 28050—2011 National food safety standard: general rules for nutrition labeling of prepackaged foods. There was no significant difference in hardness between the compound rice and the commercial rice, yet the chewiness, springiness, cohesiveness and resilience of the compound rice were significantly (P<0.05) higher.
