Thus, current rice milling technology produces rice bran from different layers of the kernel caryopsis. The phytochemical contents of each of these fractions can vary widely, the ¦Ã-oryzanol concentration being higher in the outer bran layers ( Lloyd et al., 2000 ).
What is rice bran oil?
1. Introduction Among edible oils, rice bran oil (RBO, 20¨C25 wt% in rice bran) is a unique rich source of commercially-important bioactive phytochemicals, most of them of interest in nutrition, pharmacy and cosmetics ( Da Silva et al., 2005, Danielski et al., 2005 ).
What is rice bran oil (RBO)?
Rice bran oil (RBO) (20¨C25 wt% in rice bran) is a unique rich source of commercially-important bioactive phytochemicals, most of them of interest in nutrition, pharmacy and cosmetics.
How is -oryzanol extracted from rice bran oil?
3.2. Chemical and physical refining of rice bran oil ¦Ã-Oryzanol and most other phytochemicals are largely lipophilic, and thus are extracted with the RBO; however, differently from tocols, ¦Ã-oryzanol is transferred to soapstock during the neutralisation step of chemical refining of RBO ( Narayan, Barhate, & Raghavarao, 2006 ).
