摘要: 以苦荞为原料,按蒸谷米工艺生产全营养苦荞米。在单因素筛选基础上,通过正交试验,优化产品中高含量抗性淀粉(RS)形成的工艺参数。结果表明,水分含量对营养苦荞米RS的形成影响最大,4℃静置有利于RS晶束的形成,60℃干燥有利于RS晶束的生长,pH值无显著影响。全营养苦荞米抗性淀粉形成的最佳工艺参数为:浸渍籽粒水分含量50%、汽蒸压热温度130℃、时间60min、干燥温度60℃。

Abstract: Whole nutrient tartary buckwheat rice (WNTBR) was manufactured by processing techniques of the parboiled rice. In this study, orthogonal designs L9(34) were adopted for optimization of process parameters of resistant starch (RS) in processing WNTBR. The results showed that the water content is significant factor and pH has no significant effect on production of RS. Keeping the sample at 4 ℃ is beneficial to the formation of the crystal beam of RS. Drying the sample at 60 ℃ improved the development of the crystal bundle of RS. The optimal parameters for production of RS in processing WNTBR are water content 50%, autoclaving temperature 130 ℃, autoclaving time 60 min and drying temperature 60 ℃.
