摘要
目的获得新疆某品牌驴乳粉的总糖含量和血糖负荷指数(GL),进而用来指导糖尿病患者对于驴乳粉的科学合理消费和食用量。方法送检3组驴乳粉平行样,采用高效液相色谱法进行总糖及乳糖含量的测定;采用国际通用方法测定新疆驴乳粉的血糖负荷指数。选取符合条件的新疆某高校汉族男性大学生健康志愿者10名,抽取清晨空腹静脉血5 mL记为0 min,在服用葡萄糖粉水溶液后15、30、45、60、90、120 min分别抽取5 mL静脉血,测定各时点血液中血糖水平。间隔7 d后,按照同样的试验方法,抽取志愿者5 mL空腹血后,志愿者服用含等量碳水化合物的驴乳粉水溶液,再分别抽取其余6个不同时点血样,测定其血糖水平;以葡萄糖为参照物,根据ISO26642-2010方法计算驴乳粉的生糖指数;采用国际通用的血糖负荷指数计算法获得驴乳粉的血糖负荷指数。结果新疆驴乳粉的总糖含量为69.8 g/100 g,属于中等生糖指数食物。血糖负荷指数(GL)为(12.82±5.91),属于中GL食物。食用驴乳粉后血糖应答水平未出现明显波动,血糖呈现“缓升缓降”状态。结论糖尿病患者可以每天食用30 g左右的驴乳粉,食用后血糖水平呈相对稳定的态势。
Objective To obtain the total carbohydrates and glycemic load of a brand of donkey milk powder in Xinjiang,which is used to guide the scientific and rational consumption of donkey milk powder for diabetic patients.MethodsDelivering three parallel samples groups of donkey milk powder,and using the High Performance Liquid Chromatography to measure the total carbohydrates and lactose.The glycemic load of the donkey milk powder was determined by an internationally accepted method.Ten healthy volunteers of Han nationality male college students from a certain university in Xinjiang were selected.5 mL of fasting venous blood in the morning was taken and record it as 0 min,and taken at 15 min,30 min,45 min,60 min,90 min,120 min after drinking the glucose powder aqueous solution.After 7 days,5 ml of fasting blood samples were taken at the same time points as the previous way before and after donkey milk drinking.The blood glucose level of them were measured.Using glucose as a reference,the glycemic index of the donkey milk powder was calculated according to the method of ISO26642-2010;the glycemic load index of the donkey milk powder was obtained by the internationally accepted calculation method.ResultsThe content of total carbohydrates of Xinjiang donkey milk powder is 69.8 g/100 g,which belongs to the medium glycemic index food.And the glycemic load index(GL)is(12.82±5.91),which belongs to the medium GL food.After eating donkey milk powder,the level of blood glucose response did not fluctuate significantly,and the blood glucose showed a state of“slow rise and slow fall”.ConclusionDiabetics can eat 30 g of Xinjiang donkey milk powder every day,and the level of blood glucose is relatively stable after eating.
