Journal Title: Eksakta: Jurnal Ilmu-Ilmu MIPA - Year 2017, Vol 17, Issue 2
Abstract
The objectives of the study are to obtain optimum yield of extraction red rice bran oil, to determine the physico-chemical characteristics, and componen coumpounds. Data was analyzed using Nir Parametric Statistics by Friedmann test. The resultshowed theoptimum extraction resultswasobtained by the ratio of substrate : solvent of 1: 8 andtheoil yield was 12.31 ± 0.325%. The physico propertiesofredrice bran oil were greenish browncolour, with a density rangedfrom 0.908± 0.014 to 0.922 ± 0.014 (g/mL), andthewater content rangedfrom 0.87 ± 0.06 to 0.91 ± 0.02 %. The chemical properties of redrice bran oilwere: the acid number rangedfrom 116.41 ± 1.22 to 118.11 ± 2.45 (mg NaOH/g); the saponificationnumberrangedfrom 193.74 ± 21.88 to 199.62 ± 12.63 (mgKOH/g); andtheperoxide numberranged from 24.37 ± 2.44 to 26.07 ± 4.88 (mgek/kg), respectively.Oils was analyzed used GC-MS. The chemical components of rice bran oil are oleic acid (46.24%), palmitic acid (18.25%), linoleic acid (13.29%), 9-octadecane (7.76%).
