Abstract
This study was done to evaluate the quality of crude oil from soybeans stored under different conditions. The grains were harvested at 18% (w.b.) moisture content (m.c.), and after drying to 11.2, 12.8 and 14.8% they were stored at 20, 30 or 40 ºC. Changes in free fatty acid (FFA) content, peroxide, iodine and photometric color index of the extracted oil were determined at 45-day intervals for 180-day storage. In general, oil FFA content increased in all the samples, except in grains at 11.2% m.c. and stored at 20 ºC. The peroxide and photometric color index increased significantly, independently of storage conditions; however, the increase was more accentuated in oil extracted of stored grains at high m.c. and temperature. It was concluded that crude oil quality is not affected during 6-month storage of soybeans up to 15.0% m.c. (w.b.) at 20 ºC, and for storage at 30 ºC, the grain moisture up to 13% maintains oil quality within the Brazilian market standards.
