Abstract
A process for the extraction of oil from vegetable materials comprises subjecting the vegetable material to a multi-stage counter-current solvent extraction with a hydrophilic organic solvent or a mixture of solvents in which the material moves forwardly and the extraction liquor moves rearwardly characterized in that the water content of the extraction liquor in the first stage is adjusted so that in said first stage the material is in contact with a mixture of the solvent and a substantial quantity of water and in the succeeding stages the material is in contact with solvent containing progressively less water and further characterized in that the quantity of solvent and water and the number of stages is regulated to ensure that a minimum quantity of oil separates from the extraction liquor as a separate phase in the first stage and that substantially no oil separates as a separate stage in at least the last extractive operation and in that the oil which separates as a separate phase in the remaining stages is separated from the extraction liquor after said extraction liquor leaves one stage and before it is passed to the next stage. Suitable solvents include acetone, a mixture of ethyl alcohol, ethyl acetate and acetone in equal proportions by volume and a mixture of ethyl alcohol, ethyl acetate and isopropyl ether in a ratio of 4 to 2 to 1 by volume. The starting material should contain from 20 to 70% by weight of water; some starting materials, such as coconut, possess this amount of water naturally, in other instances it is necessary to add water to the raw material. Water soluble substances, mainly carbohydrate, are extracted from the starting material in the first stage and may be recovered if desired. The oil which separates as a separate phase may may be separated by gravity, decantation or centrifuging, and traces of solvent removed therefrom by heating preferably in a vacuum. Examples are given of the application of the process to rice bran, soy bean, cotton seed, ground nuts, maize germ, coconut, and the coffee grounds remaining after the extraction of water soluble "instant" coffee from coffee beans.ALSO:The residue from the counter-current solvent extraction of oil (see Division C5) from vegetable materials such as rice bran, ground nuts, soybeans, cottonseed, maize germ, coconut and coffee grounds by means of an aqueous organic solvent comprises an almost tasteless material rich in protein and suitable for human or animal food.ALSO:The residue from the counter-current solvent extraction of oil (see Division C5) from vegetable materials such as rice bran, ground nuts, soybeans, cotton seed, maize germ, coconut and coffee grounds by means of aqueous organic solvents comprises an almost tasteless high-protein material suitable for use as human or animal food.
