Abstract
This report, which describes technical and economic aspects of edible oil recovery from bran stabilized by extrusion cooking, is based upon 1979 site visits to India, Egypt, and Burma, and interaction with persons involved in those phases of rice delivery systems expected to impinge upon rice bran oil production. Models are described in which bran produced at small or large two-stage rice mills is stabilized either in centralized or decentralized operations and is then subjected to oil extraction and refining. The effects upon return on investment of variable stabilization and bran costs and oil extraction and refining yields are examined. Edible oil recovery from rice bran is shown to be economically feasible under a wide range of technical and economic conditions. Data used to arrive at this conclusion should be applicable to situations in other countries. This project was carried out by the Office of International Cooperation and Development, and the Western Regional Research Center, U.S. Department of Agriculture, on behalf of the Office of Nutrition, U.S. Agency for International Development.
