摘要: 利用挤压技术制备一款富含膳食纤维的复配米。以碎糙米、鹰嘴豆、燕麦作为原料,以综合得分为指标,通过单因素试验和响应面试验优化挤压工艺条件。结果表明:最佳工艺参数为螺杆转速160 r·min-1,挤压温度140 ℃,水分含量33%,鹰嘴豆添加量16%,燕麦添加量19%,碎糙米添加量65%。在此条件下,复配米的综合评分为75.96±0.50,感官评分为92.85±2.11,膳食纤维含量为12.65%,可溶性膳食纤维含量达到6.93%,符合《食品安全国家标准 预包装食品营养标签通则》(GB 28050—2011)对“高膳食纤维”标注的要求。制备的配复米的硬度与市售米无显著差异,但其咀嚼性、弹性、黏聚性和回复性均显著(P<0.05)更高。

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.
