摘　　要：以糯米粉为基料,添加药食同源的中药茯苓、淮山药、莲子、红枣,开发一种能调理婴幼儿脾胃虚寒、腹胀腹泻的即食型糯米粉。依据单因素实验绘制热风和微波干燥曲线,并根据两种干燥的最适条件进行正交实验,确定最佳干燥参数;然后用正交实验对原辅料进行最佳配比实验。结果表明:原辅料最佳配比为100g基料中添加茯苓和红枣各14g,淮山药10g,莲子8g;先用300W微波干燥1.5min,后70℃热风干燥2h;粉碎后添加24%的木糖醇。采用微波热风联合干燥法生产即食型保健糯米粉可有效保持原料固有成分,且具有良好的感官性状。In order to prevent the taste cold empty and abdominal distension diarrhea of infants,the edible traditional Chinese medicine poria cocos,dioscorea opposita thunb,lotus seed,and jujube were added into glutinous rice powder,and then the health glutinous rice powder was developed for infants.The curves of hot air and microwave drying were drawn based on a single factor experiment,and the best drying parameters were determined according to the orthogonal test under two dry optimal conditions,the best proportion of raw materials was determined by other orthogonal experiments.The results showed that the best parameters of dying were microwave 300W,1.5min,and then hot air drying 70℃,2h.The best ratio of raw material was 14g poria cocos and jujube,10g dioscorea opposita thunb,8g lotus seed were added into 100g glutinous rice,and 24% xylitol was added after being smashed.The combination drying method of hot-air drying with microwave drying could effectively keep raw natural composition and good sensory properties when health care glutinous rice powder was produced.
