The alpha-amylase activity in whole saliva of two groups of infants was investigated from birth to 5 months at monthly intervals. Foods used in infant feeding as well as height and weight were recorded at each monthly collection period. alpha-Amylase activity was found to increase rapidly from low values at birth to approximately two-thirds of adult values by 3 months. Large variation in alpha-amylase activity, either per ml of saliva or per mg of protein, was recorded. No significant relationships of alpha-amylase activity with weight, weight for height, growth rate, or presence of starch-containing foods in the diet were found. Introduction of starch-containing food before 3 months of age would likely lead to inadequate hydrolization of starch in some infants.
对两组婴儿从出生到5个月期间每月采集的全唾液中的α-淀粉酶活性进行了研究。在每个月的采集期记录婴儿喂养所用的食物以及身高和体重。发现α-淀粉酶活性从出生时的低值迅速增加，到3个月时达到成人值的约三分之二。记录到每毫升唾液或每毫克蛋白质的α-淀粉酶活性存在很大差异。未发现α-淀粉酶活性与体重、身高体重比、生长速率或饮食中含淀粉食物的存在有显著关系。在3个月龄前引入含淀粉食物可能会导致一些婴儿淀粉水解不足。
