| 摘 要： | 普洱茶籽油中所含的金属是引起普洱茶籽油酸败、高温褐变的主要原因.为了有效降低普洱茶籽油中的金属含量,采用火焰原子吸收光谱法,比较了水化脱胶、磷酸脱胶、柠檬酸脱胶法获得的脱胶普洱茶籽油中的Fe、Cu、Mn、Mg等金属的含量.结果表明,磷酸脱胶对油中金属的去除效果最好.

| Abstract: | The rancidity and browning at high temperature were mainly induced by the metal in puer tea seed oil.The contents of Fe,Cu,Mn,Mg in the tea seed oil obtained by hydration degumming,phosphoric acid degumming,citric acid degumming method,were determined using flame atomic absorption spectrometry.The results showed that phosphoric acid degumming could effectively remove the metal in the oil. |
