目的:测定普通奶与高钙奶中的钙含量.方法:对牛奶样品进行干式灰化,并用EDTA滴定法测定牛奶中的钙含量.结果:结果表明,普通牛奶中钙含量为104.2 mg/100g,普通酸牛奶为105.2 mg/100g,高钙牛奶为118.1mg/100g,高钙酸牛奶为115.1mg/100g.结论:高钙奶与普通奶中钙含量差别不大,饮用普通奶补钙更经济实惠.
Objective:To determine the calcium concentration in ordinary milk and high calcium milk.Methods:Milk samples were treated by dry-ashing method, the calcium concentration of milk samples were determined by EDTA titration. Results:The result showed that the calcium concentration of ordinary milk was 104.2 mg/100g, the calcium concentration of ordinary yoghurt was 105.2 mg/100g, the calcium concentration of high calcium milk was 118.1mg/100g, the calcium concentration of high calcium yoghurt was 115.1mg/100g. Conclusion: There was so little difference between calcium concentration in ordinary milk and high calcium milk, Calcium supplementation by drinking ordinary milk is more economical.
