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 ).
Is -oryzanol a value-added co-product of rice bran processing?
¦Ã-Oryzanol is an important value-added co-product of rice bran processing. Therefore, research to improve the recovery of ¦Ã-oryzanol and other phytochemicals, in order to obtain fractions enriched in a particular compound or group of compounds, has been conducted.
How is rice bran produced?
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 ).
