1 Newer Processing Methods for the Extraction and Refining of Rice Bran Oil By S. M. Javed Husain MUEZ-HEST INDIA PVT. LTD. Global Rice Bran Oil Conference 2015 August 7-8 th 2015 Trident Hotel, Mumbai, India

2 RICE PADDY Rice is the seed of the monocot plants Oryza sativa (Asian rice) or Oryza Glaberrima (African rice). As a cereal grain, it is the most important staple food for a large part of the world's human population, especially in East Asia, Southeast Asia, South Asia, the Middle East, and the West Indies.

FATTY ACID SOYA LECITHIN RICE BRAN RICE BRAN LYSO LECITHIN LECITHIN 14: : : : : : Acid Value of Rice Bran and Soya Lecithin: Rice Bran Lecithin More Oxidative Stability due to less content of Linoleic and Linolenic acids Rice Bran Lecithin contains Oryzanol and Tocotrienols which enhances its Value, hence very useful as efficient emulsifier, growth promoter and so on
