中文摘要: 为开发一种必需氨基酸含量均衡且估计血糖生成指数(estimated glycemic index,eGI)低的功能性即食杂粮粉,将薏仁、苦荞、燕麦、小米、绿豆、黑豆和鹰嘴豆粉单独挤压加工,以挤压后原料的eGI值为指标,将eGI值较低的燕麦、苦荞和黑豆确定为即食杂粮粉的目标原料。通过氨基酸评分原则确定苦荞、麦、黑豆的适宜配比为52∶35∶13(质量比)。通过单因素试验和正交试验,以水溶性指数为指标(water solubility index,WSI)确定杂粮粉的适宜挤压工艺参数为物料加水量14%,挤压温度120℃,螺杆转速360 r/min,此条件下杂粮粉的WSI为8.98%。
Abstract:In order to develop a functional ready-to-eat multigrain powder with balanced content of essential amino acids and low estimated glycemic index(eGI),the coix seed,tartary buckwheat,oats,millet,mung bean,black bean,and chickpea flour were extruded separately.With the eGI value of the raw materials after extruding as the index,the oats,tartary buckwheat,and black bean with lower eGI value were selected as the target raw materials of ready-to-eat multigrain powder.According to the amino acid scoring principle,the optimum ratio of tartary buckwheat,oats,and black bean was 52∶35∶13 (mass ratio).Through single factor test and orthogonal test,the water solubility index(WSI)was used as the index to determine the optimal extrusion process parameters of multigrain powder as follows:water addition of 14%,extrusion temperature at 120 ℃,and screw speed at 360 r/min.Under these conditions,WSI of multigrain powder was 8.98%.
