106名4～6岁营养中等的儿童食用三种强化食品(强1、强2、强3)5个月,每两强化饼干或每个强化面包可供给蛋白质6g,热能160kcal。“强1”加赖氨酸盐酸盐0.25g。“强2”中除赖氨酸外又加入核黄素0.8mg,“强3”除赖氨酸、核黄素外又加少量鱼肝油及钙粉。对照组食用未经强化的普通面包或饼干。实验结果表明“强1、强2”组的身高、体重月增加值显著高于对照组,氮存留量有增高趋势,而“强3”组实验后期热能摄入量有所减低,氮存留量有减少趋势。强1、强2组尿肌酐日排出量也显著增加,实验后核黄素负荷试验,尿中排出率显著增加,而强1组有微减趋势,由此可见,在摄入热能71kcal/kg,蛋白质2.1g/kg的条件下,平均每日增加赖氨酸228mg,核黄素1.1mg时有助于生长发育、氮存留量和核黄素营养状况的改善。仅仅增加蛋白质和赖氨酸可加重核黄素的不足,加入鱼肝油、钙粉等,影响食物感官性状,儿童不爱食用。三种食品中以“强2”效果为最好。
106 children aged 4 to 6 years with moderate nutrition consumed three fortified foods (Strong 1, Strong 2, Strong 3) for 5 months. Each fortified biscuit or fortified bread provided 6 grams of protein and 160 kcal of heat. “Strong 1” plus lysine hydrochloride 0.25g. “Strong 2” in addition to lysine and added riboflavin 0.8mg, “strong 3” in addition to lysine, riboflavin plus a small amount of cod liver oil and calcium powder. The control group consumed plain bread or biscuits without reinforcement. The experimental results showed that the monthly value added of height and weight of Qiang 1 and Qiang 2 groups was significantly higher than that of the control group, while the nitrogen storage tended to increase while that of Qiang 3 group was decreased, nitrogen storage There is a downward trend. Strong 1, strong 2 groups of urinary creatinine daily discharge also significantly increased after the test of riboflavin load test, urinary excretion rate increased significantly, while strong 1 group there is a slight downward trend, we can see that the intake of heat 71kcal / kg , Protein 2.1g / kg, the average daily increase of lysine 228mg, riboflavin 1.1mg contribute to the growth and development, nitrogen storage and riboflavin nutritional status improvement. Just increase the protein and lysine can increase the lack of riboflavin, add cod liver oil, calcium powder, affect the sensory properties of food, children do not like to eat. Three foods in the “strong 2” effect is best.
