Patent number: 5445841Abstract: A method of obtaining oil from grain materials such as rice bran, wheat mill feed, rapeseed, amaranth, and similar grains, by stabilizing the oil contained in the grain material (when necessary) while increasing the porosity of such grain material; extracting oil from the grain material by contact with a solvent in vapor form; and, separating extracted oil/solvent compositions into fractions containing various amounts of saturated and unsaturated oils. A solvent in vapor form is also used to remove oils from: previously-extracted oil seeds, which were extracted using a less efficient extraction method; flaked or crushed vegetable matter; and grain-based food products such as chips, crackers and noodles.Type: GrantFiled: February 1, 1993Date of Patent: August 29, 1995Assignee: Food Sciences, Inc.Inventors: Phillip S. Arendt, Charles E. Langley

Patent number: 5278325Abstract: A vegetable oil process and assembly is disclosed for extracting oil from an oil bearing material such as soybean, corn and the like. The process comprises adding at least one reagent to the oil bearing material to form a slurry mixture. The slurry is heated at a preselected temperature for a preselected period of time preferably under a partial vacuum. This processing reduces the phospholipid and trace metal content in the oil extracted from the oil heating material. The oil product produced is light in color, shows no turbidity and exhibits minimal amount of phosphorus, calcium, magnesium and iron. The oil is ready for physical refining.Type: GrantFiled: July 30, 1990Date of Patent: January 11, 1994Inventors: Hans R. Strop, Richard R. Perry

Patent number: 5241091Abstract: The method of extracting a physiological active substance in which a granular acid polysaccharide is a principal component is disclosed. The husks of the pine nuts are immersed in an alkali solution to proceed an extraction treatment. The obtained extract is filtered and insoluble substances are separated and then remained solution is concentrated and arranged its degree of pH. Thus physiological active substance in which a granular acid polysaccharide is a principal component is extracted through lyophilization treatment. The anti-contagion medicine in which an acid polysaccharide obtained by the extraction method is a principal component provides with an activation function which by far surpasses an activation function of the polymorphonuclear leukocyte of conventional anti-tumor polysaccharides.Type: GrantFiled: September 3, 1991Date of Patent: August 31, 1993Assignee: Masazumi YoshiharaInventors: Masazumi Yoshihara, Hiroshi Sakagami

Patent number: 5182406Abstract: The process for recovering vegetable oleaginous substances from oil-containing natural substances comprises a series of continuous combined pressing and extraction steps to increase and simultaneously to guarantee a high quality product for different kinds of natural substance starting materials. This is accomplished by subjecting the natural substances, conditioned and comminuted if necessary, after mixing with a solvent phase containing some oil to an intensive processing, mixing and extraction in the shear field of at least one rotor-stator unit and subsequently feeding the resulting liquid phase, through a filter if necessary, to a distillation column. The solid phase is extracted in successive stages until a residual oil content of 1% is reached and the solvent is fed back to a solid phase in a counterflow. The process as defined in my invention is universally applicable to all fat and oil-containing natural substances using suitable fluid extraction means.Type: GrantFiled: April 5, 1991Date of Patent: January 26, 1993Assignee: Dorr-Oliver Deutschland GmbHInventor: Hubert Coenen

Patent number: 5112637Abstract: The present invention is drawn to a process for extraction of gossypol for cottonseed using a solvent solution which includes: (a) a water miscible organic solvent; (b) water; and (c) an acid which is strong enough to prevent binding of gossypol to cottonseed protein but which is not so strong as to hydrolyze a substantial portion of the cottonseed protein. The present invention also includes cotton seed meals of reduced gossypol content (and optionally reduced aflatoxin and/or fat content) produced by the aforementioned extraction.Type: GrantFiled: November 5, 1990Date of Patent: May 12, 1992Assignee: The United States of America as represented by the Secretary of AgricultureInventors: Robert J. Hron, Sr., George Abraham, Myong S. Kuk, Gordon S. Fisher
