摘要:

介绍了一种快速可行的奶油酸值的测定方法,该方法基于FOX3000型电子鼻对不同酶解程度的奶油做酸值线性模型分析,建立最小回归定量分析模式(PLS)酸值标准曲线,对未知酸值的奶油快速检测,准确性为93.85%,此方法便于实验室和工业化生产使用。

关键词: 电子鼻, 奶油, 酶解, 酸值

Abstract:

This study aimed to develop a rapid and feasible method for determining acid value of cream using a partial least-squares (PLS) regression model built up based on linear model analysis of acid values of different enzymatic hydrolysis degrees of cream measured using an FOX3000-type electronic nose. The electronic nose-based determination for unknown acid value of cream exhibited an accuracy of 93.85%. This method can be conveniently used in both of lab research and industrial production.

Key words: electronic nose, milk, enzymolysis, acid value
