What is the yield of rice bran oil extracted by cold pressing?
Pengkumsri et al. [ 30] registered 4.04¨C5.80% yield of rice bran oil extracted by cold pressing at?<?60 °C with pronounced increase of oil yields by 44% for hot pressed rice bran oil at 100 °C. Moreover, supercritical fluid afforded a 12.89% oil yield using 1 h extraction time, which was lower (<?10%) than that obtained using hexane extraction.
How is rice bran oil extracted?
The rice bran oil extracted with hexane extraction (HE), cold-pressed extraction (CPE), supercritical fluid carbon dioxide extraction (SF-CO 2 ), and subcritical liquefied DME extraction (SUBLDME). Table 2.
What is rice bran oil?
Rice bran oil (RBO) is unique among edible vegetable oils because of its unique fatty acid composition, phenolic compound (¦Ã-oryzanol, ferulic acid) and vitamin E (tocopherol and tocotrienol). It has become a great choice of cooking oil because of its very high burning point, neutral taste and delicate flavour.
