Abstract

The invention discloses a method for identifying the production place of turmeric essential oil based on a Raman spectrum technology. The method uses qualitative and quantitative identification methods at the same time, and comprises the following specific steps: (1) collecting a calibration set verification set and processing Raman spectrum data; (2) establishing a judgment model: (2.1) establishing a PCA qualitative judgment model, and (2.2) establishing a PLS-DA quantitative judgment model; and (3) measuring the sample to be measured. The method has the characteristics of small identification error, high identification speed and no damage.

Description

technical field

[0001] The invention relates to a method for identifying the origin of turmeric essential oil, in particular to a method for identifying the origin of turmeric essential oil based on Raman spectrum technology. Background technique

[0002] The origin of turmeric essential oil has always been a concern. Turmeric essential oil in different production areas has different contents of main components, and there are also great differences in efficacy and price. Therefore, it is of great significance to identify and identify turmeric essential oils from different production areas. At the same time, identifying whether it is an essential oil produced in a certain area can also avoid the situation of shoddy. Since the main color and taste of turmeric essential oil do not vary much between different production regions, traditional methods such as sensory evaluation are not reliable in this case. As a traditional method of identifying essential oils, liquid chromatogr...
