    摘要:

    目的:建立茶籽油掺假的快速定性和定量检测方法。方法:采用电子鼻技术结合化学计量学,基于单因素方差分析筛选差异变量,通过主成分分析(PCA) 和判别分析(DA)建立茶籽油掺假类型鉴别的定性模型;通过正交偏最小二乘法(OPLS)建立了茶籽油掺假类型和掺假度鉴别的定量模型。结果:模型的R2均高达0.98,RMSEE均低于0.005,RMSECV均低于0.01,具有较高性能指标。通过外部验证,DA模型对不同掺假类型的茶油样品定性识别率高达100%,OPLS模型具有良好的准确性。结论:电子鼻技术结合化学计量学能够实现茶籽油掺假的快速、无损鉴定。

    Abstract:

    Objective: To establish a rapid qualitative and quantitative method for the adulteration of Camellia seed oil. Methods: The electronic nose technology combined with chemometrics was used to screen the difference variables based on one-way ANOVA. The qualitative model for identification of adulteration types of camellia seed oil was established through principal component analysis (PCA) and discriminant analysis (DA). A quantitative model for identifying the types and degrees of camellia seed oil adulteration was established using orthogonal partial least squares (OPLS). Results: The R2 of the model was over 0.98, the RMSEE was lower than 0.005, and the RMSECV was lower than 0.01, which had the high performance indicators. Through external verification, the qualitative identification rate of DA model for camellia seed oil samples of different adulteration types was as high as 100%, and OPLS model had good accuracy. Conclusion: The electronic nose technology combined with chemometrics could realize the rapid and nondestructive identification of camellia seed oil adulteration.
