PURIFYING USED CANOLA OIL USING Zingiber Officinale (GINGER) AS ADSORBENT

Abstract

Enormous waste of cooking oil is produced daily in households and food service industries. It can harm the consumer's or the environment's health if not handled and disposed of properly. To help lessen the disposal and over-reused consumption of used cooking oil, the researchers devised purifying used cooking oil using Zingiber officinale (Ginger) as an adsorbent. The selected cooking oil employed in this study is Canola oil, a low-cost vegetable oil widely known for its healthy content. The researcher utilized a quantitative research design to obtain the desired data. Two experiments were conducted: first, purifying the used Canola oil using Ginger, and second, testing the free fatty acid content of the unused, used, and used Canola oil. The results revealed that the FFA content of the used Canola oil is 19.18% in 5g and 16.92% in 3g. As for the purified Canola oil, the percentage in 5g is 12.41%, while it is 16.92% in 3g. The FFA content of the samples was compared using the one-way ANOVA test and paired t-test. Based on the gathered data, the results indicate a low significant difference between the free fatty acid content of the used Canola oil and purified used Canola oil is relatively low. Thus, using Ginger as an adsorbent does not significantly affect the purification process. Further research is recommended in this study as alterations, measurements, and proportions during the experimentations may affect the data results.
