Castor beans were treated with a freezing agent such as solid carbon dioxide, a mixture thereof with an organic solvent, or liquid nitrogen, prior to milling them in a grinder. The beans were solidified as a result of the freezing treatment so that there was no apparent oil loss when they were ground. The process was applied successfully both to whole and dehulled beans, as well as to other oilseeds, e.g. soyabeans, peanuts and sunflower seeds. It was possible to dehull soyabeans and to remove the skin of shelled and unshelled peanuts using this method, when freezing was conducted in a freeze dryer |
