Polytechnic Kampar has a
cooking oil plant, where students can learn the real experience of cooking oil
processing. Currently, no treatment for the spent bleaching earth as waste that
generated in the cooking oil processing. Spent Bleaching Earth resulting from
the process of bleaching in the processing still contains substances such as
oil and carotene. Extraction of carotenoids substance from spent bleaching
earth is one of the alternative recovery carotene from waste. In general, the
objectives of this research was to utilize the waste from bleaching process by
extracting carotenoids from spent
bleaching earth and analyse the extract of carotene. Thus, the utilization of
spent bleaching earth can be completed and provide added value to the cooking
oil plant. This study was conducted by mixing two (2) types of solvents, namely
acetone and hexane to separate carotenes from spent bleaching earth, that obtain
optimum conditions for both the solvent and the ratio between the sample and
the time of extraction process. The extract of carotene was analyzed using a UV
–Vis spectrophotometer . Based on the results, the highest carotene content
obtained by using acetone solvent that was 703.78 ppm with the time 24 hours
and a comparison of acetone – hexana 1 : 1 , while the highest yield was 42.62%
with the time was 16 hours .
