摘要:

采用加热实验、金属离子鉴定、气相色谱测定和红外光谱图等实验,建立硬脂酸钙、硬脂酸镁、硬脂酸钠、硬脂酸钾和硬脂酸等5 种常用硬脂酸(盐)类食品添加剂的鉴定方法。结果表明,加热实验特征现象、脂肪酸的气相色谱测定色谱图和红外光谱图是鉴定脂肪酸盐的有效指标;金属离子鉴定实验阳性明显,可作为鉴别实验中各种脂肪酸盐的有效指标。

关键词: 食品添加剂, 硬脂酸盐, 鉴定方法

Abstract:

A method using combined techniques of heating test, chemical precipitation of metal ions, gas chromatography and infrared (IR) spectroscopy was proposed for the identification of five stearates including stearate acid, calcium stearate, magnesium stearate, sodium stearate and potassium stearate that are commonly used as food additives. In this method, metal ions in stearate salts were identified using chemical precipitation methods, and fatty acids were identified according to gas and IR spectra.

Key words: food additives, stearate salts, identify method
