利用缓冲能力检测桑果汁饮料中果汁含量的方法研究

桑果原汁是一种缓冲溶液,其含量不同则缓冲能力大小不同,即由桑果原汁调配的桑果汁饮料的溶液pH随添加的柠檬酸的量的变化幅度不同,设计实验得出桑果汁饮料的缓冲系数与其中桑果原汁含量的关系式,根据该关系式可以推算出桑果汁饮料中桑果原汁的含量。

Raw mulberry juice is a buffer system. The buffer capability is different with different contents of raw mulberryjuice. Citric acid was added into the mulberry juice drink of different contents of raw mulberry juice and pH was recordedsimultaneously. An equation of the relationship of citric acid and H+ was concluded. Using this equation, the contents of rawmulberry juice in mulberry juice drink could be calculated.
