简便高效的“小京生”花生还原糖含量测定分析

Simple and Efficient Determination Analysis of the Reducing Sugar Content of “Xiaojingsheng” Peanut

新昌“小京生”花生由于含糖量较高,口感“香而甜”。采用直接滴定法可以有效的测定“小京生”的还原糖含量,且实验重复性好。对不同等级“小京生”的还原糖含量测定表明,其含量在0.1042%~0.1881%之间,且品质越好其还原糖含量越高。该研究结果为“小京生”的品质鉴定和质量标准化提供一个数量依据。

Xinchang“Xiaojingsheng”peanuts have high sugar content and a“sweet and sweet taste”.The direct titration method can effectively determine the reducing sugar content of“Xiaojingsheng”,and the experiment repeatability is good.The determination of reducing sugar content of different grades of“Xiaojingsheng”indicates that the content is between 0.1042%and 0.1881%,and the better the quality is,the higher the reducing sugar content is.The research result provides a quantitative basis for the quality identification and quality standardization of“Xiaojingsheng”.
