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 using two (2) types of
solvents, namely hexane and acetone 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 506.93 ppm
with the time 24 hours and a comparison sample - solvent 1 : 2 , while the
highest yield was 63.32% by using hexane as the solvent with the ratio with
samples - solvent 1 : 2 , and 24 hours .
