测定酱油中还原糖含量的一种新方法

A New Method of Determinating Reducing Sugar in Soy Sauce

采用蓝-艾农法和还原糖测定仪法测定酱油中还原糖的含量。结果表明,2种方法均能较好地测定酱油中还原糖的含量。还原糖测定仪法使用方便、测定迅速、回收率可达99%以上,是测定酱油中还原糖的更为理想的方法。

Lan-Eynon and the reducing sugar analyzer were used to analyze the content of reducing sugar in soy sauce. The results showed that both analyzer and ordinary methods can determine reducing sugar in soy sauce. The reducing sugar analyzer, especially, can determine reducing sugar in soy sauce more conveniently, rapidly and the recovery rate generally reached over 99%. Therefore it is a better method to determine the reducing sugar content in soy sauce.
