摘　　要：目的评价复配式粗杂粮的营养成分及其血糖生成指数(GI),探讨其营养成分与生物功效的关系。方法按国家标准方法分别测定复配式粗杂粮及对照食物一般营养素含量。取含有50g碳水化物的复配式粗杂粮制成馒头,50g葡萄糖为对照物,10名志愿者测空腹血糖后,服用2种食品,测定3h内不同时间的血糖水平,依照Wolver方法计算食物的GI值。结果复配式粗杂粮每100g中含不溶性膳食纤维(粗纤维)13·7g、维生素B10·40mg、蛋白质13·5g、灰分2·0g、维生素B20·16mg、钙54mg、铁7·1mg、锌3·00mg。其餐后血糖绝对增加值和血糖反应曲线下增值面积显著低于葡萄糖(P<0·05),GI值为52·6。结论复配式粗杂粮中较高含量的蛋白质、矿物质、粗纤维和维生素B1、B2,特别是比较低的GI是复合式营养干预取得较好效果的重要原因。Objective To evaluate the nutrients contents and the glycemic index （GI） of the mixed grains and analyze the relationship between the nutrients contents and biological effect. Methods The nutrients contents of mixed grains and control food were determined according to the methods of Chinese national standards. Choose 10 volunteers to ingest 50g glucose and ingest the steamed bread of mixed grains which imply 50g carbohydrate the second day. Limosis blood glucose and blood glucose levels duriag the subsequent 3 hours were determined. Calculating the GI according to the Wolver＇ s method. Results The results showed that 100g of the mixed grains contained dietary fiber（crude fiber） 13.7g, vitamin B1 0.40mg, protein 13.5g, ash2.0g, vitamin B2 0.16mg, calcium 54mg, iron 7.1 mg and zinc3.00mg respectively. The absolute increase of blood glucose and the areas increased under the glycemic curves of mixed grains were less than which of glucose （ P 〈 0.05）. The GI of the mixed grains bread was 52.6. Conclusion It was concluded that the high contents of protein, minerals, dietary fiber, VB1, VB2 and the low GI of mixed grains might play an important role in nutritional intervention.
