Qualitative Assessment of Cooking Oil using Diffuse Reflectance Spectroscopy Technique
2022 International Conference on Green Energy, Computing and Sustainable Technology (GECOST)(2022)
Abstract
In this study, reflection spectroscopy technique has been used in determining the oil quality. Conventional methods such as chemical testing consumes some costs and time and not accurate enough. The samples used were bottled palm cooking oil, subsidized cooking oil, and recycled cooking oil from different brands and collected area. Two different sample condition were applied which is different type of cooking oil and different concentration of recycle cooking oil mixture that were used for analysis and their reflection spectrum were measure at 200 nm - 900 nm. The computer simulation was used to process the data based on their pattern recognition. From the analysis, it is found that reflection spectrum is influenced by concentration of foreign compound in the cooking oil sample. This indicate the reflection spectroscopy technique can be used to detect the present of foreign compound in the palm cooking oil, thus providing the difference of quality assessment of cooking oil.
