Abstract

The availability of zinc and calcium from human, cow's, goat, and sheep milk is evaluated by an in vitro method that involves a simulated human gastrointestinal digestion followed by measurement of dialyzability of zinc and calcium. Zinc availability of milk showed the highest value for human milk (15.0%) and the lowest for sheep milk (1.0%), in both whole and skim milk. Calcium availability of the different types of milk did not differ significantly and ranged between 18 and 23%. No significant differences in availability between whole and skim milk were found for both elements, except for zinc in cow's milk.

摘要

采用一种体外方法评估人乳、牛乳、山羊乳和绵羊乳中锌和钙的可利用性，该方法包括模拟人体胃肠道消化，然后测量锌和钙的透析率。全脂奶和脱脂奶中，人乳的锌可利用性最高（15.0%），绵羊乳最低（1.0%）。不同类型牛奶的钙可利用性无显著差异，范围在18%至23%之间。除了牛乳中的锌，两种元素在全脂奶和脱脂奶中的可利用性均无显著差异。
