摘要
维生素C含量的多少,是评价各种果汁饮料质量的重要指标之一,在深色果汁饮料中,用常规的方法很难测得维生素C的准确含量。本研究通过大量的试验分析,采用萃取比色法测定深色果汁饮料中维生素C的含量,并与AOAC,ISO,IFIU等测定维生素C含量标准方法对比,证明本法的可靠性,准确性很高,目前已在教学,科研和食品检测中获得应用。
The content of Vc is one of the most import index when evaluating of various juices. The accurate content of Vc can the quality not be measured on regular method. After lots of experiments and analyses the author adopts the extraction method and colorimetry to determine the content, compares this method with the standard AOAC, ISO and IFJU etc, This method, is of reliability and accuracy. It has been used in teaching, researching and detecting of food.
