Aqueous extraction experiments were conducted in laboratory scale mixer–settler unit. Steaming, hot air drying,
chemical stabilization and refrigeration better controls the lipase activity compared to solar drying. Steaming is the
most effective stabilization technique. The extraction capacity was highest at solution pH range 10–12. Higher oil
yieldwas observed at higher operating temperatures (60–80 ◦C). Kinetic studies revealed that extractionwas fast with
95% or more of the extraction occurring within first 10–15 min of contact time. Parboiling of paddy increases the oil
yield. Highest oil yield of 161 and 131 mg/g were observed for aqueous extraction of parboiled bran and raw rice bran
respectively. The aqueous extracted oil was low in free fatty acid content and color compared to hexane extracted
rice bran oil and other commonly used oils. Major lipid species in rice bran oil were oleic, linoleic and palmitic
