添加混合果汁的生物钙剂中钙的吸收利用率的研究

由海洋生物牡蛎壳、对虾皮加工而成的生物钙粉，添加混合果汁（桔子汁、苹果汁、山楂汁和大枣汁）制成钙冲剂。用钙冲剂与其它几种常用补钙剂（活性钙、葡萄糖酸钙、乳酸钙、磷酸氢钙）进行了３０天大鼠喂养及３天代谢实验。结果显示：此种钙冲剂钙的吸收率和储留率分别为６９．２％和９５．１％，均高于其它钙剂（Ｐ＜０．０５），大鼠股骨重量（湿重）和股骨含钙量分别为（０．８２±０．０４）ｇ和（８．４５±６．２）ｍｇ，均大于其它各组（Ｐ＜０．０５）。

The Experimental Study on Absorption and Utilization of Calcium from Oyster Shell Powder Mixed with Fruit Juice

A new kind of calcium powder was prepared from the shell of oyster and the bones of other sea lives, in which fruit juice was mixed.This calcium powder and other four different forms of calcium (i.e,active calcium,gluconate,lactate,and phosphate) were fed to 4 groups of Wistar rats for 30 days. 3 days calcium metabolism test was done.The absorption and retention rates of calcium powder were 69 2% and 95.1% in the experimental group, which were higher than those in other calcium supplement groups ( P <0 05).The weight of femurs and the total calcium content of femurs had significantly increased in calcium powder group ( P <0 05).These findings indicated that calcium from calcium powder, which was prepared from sea lives and mixed fruit juice was more effective.
