电子舌传感器快速检测油茶籽油中掺杂棕榈油

Rapid Detection of Adulterated Palm Oil in Camellia Seed Oil by Electronic Tongue

为检测油茶籽油中掺杂不同程度的棕榈油,先用传统化学方法检测掺入0%、5%、10%、15%、20%、100%棕榈油的各项理化指标,再利用法国Alpha M.O.S公司生产的传感器型味觉电子舌系统对其进行检测,所得样品数据用主成分、判别因子以及相似性法进行分析。结果表明,当选择ZZ与GA传感器时,主成分分析图识别指数达到87,能够明显鉴别出油茶籽油不同比例的掺杂,表明电子舌在油脂检测方面有着较为广阔的应用前景。

In order to distinguish the adulteration of camellia seed oil,traditional chemical methods were used to detect physical and chemical indicators of camellia seed oil adulterated with 0%,5%,10%,15%,20% and 100% palm oil.An electronic tongue system was applied to determine the adulteration of camellia seed oil through principal component analysis,discriminant factor analysis and similarity analysis.The identification index of principal component analysis map from ZZ and GA sensors was 87,which could clearly distinguish different adulteration rates of palm oil in camellia seed oil.The results showed that electronic tongue could be a good and quick method to detect the adulteration of camellia seed oil.
