| Summary: | Rice bran contains nutritious and healthful edible oil namely rice bran oil
(RBO), it contains balance of fatty acids and unique antioxidants such as
oryzanol, tocopherol, and tocotrienol. RBO is useful as a skin nutrition, prevent
heart disease, anticancer and also has a hypocholesterolemic characteristic. RBO
can be extracted from rice bran by extraction method, but it needs pretreatment to
improve the yield and quality results. Fermentation pretreatment with Aspergillus
niger is expected to facilitate rice bran extract by breaking down the cell wall,
while protease facilitates oil release from cotyledon cells. This study was aimed to
estimate the maximum yield of RBO in the rice bran used, study the effect of
fermentation pretreatment using Aspergillus niger toward yield and quality of
RBO, analyzing the quality of produced RBO, and estimate the economic aspects
of medium industry scale in RBO production.
RBO was obtained from rice bran by solvent extraction using ethanol
96%. Process variables
