A new, rapid method for total oil analysis of soybeans is proposed in which ground soybeans are mixed with solvent and further ground in a closed homogenizer until the oil is completely dissolved. A sample of the slurry can then be filtered and the oil content determined by evaporating the solvent from a measured amount of miscella. Parameters studied included times and speeds needed to produce sufficiently small particles so that all the oil was dissolved. The new analysis compared favorably with conventional Goldfisch extraction for total oil of soybeans. Preliminary experiments indicated that rapeseed could be extracted by the new procedure without preliminary grinding.
