Abstract: Edible fats and oils are extracted from oil-bearing materials by loading the raw materials onto an inlet end of a flat and fixed conveying surface having elongate slits therein. The materials are conveyed from the inlet end to the outlet end of the conveying surface by scrapers moved by endless chains. Oil extracting solvent is sprayed onto the material on the conveying surface, to produce miscella, which flows through the slits in the surface and into hoppers beneath the surface. The miscella is circulated back to additional sprayers located upstream of the solvent sprayers for spraying the miscella onto the upstream end of the conveying surface. The resulting concentrated miscella is collected in hoppers beneath the surface and delivered to a further use.

Abstract: The present invention provides a method for promoting the proliferation of microorganisms of the genus Bifidibacterium comprising contacting said microorganisms with a growth promoting effective amount of an isomalto-oligosaccharide.

Abstract: A phytin-containing solution such as corn steep liquor, acid extract of rice bran is treated with an anion exchange resin with phytin adsorption. The phytin is then separated from the resin by alkali-elution, then the phytin thus recovered is further subjected to the treatment of hydrolysis under pressure, phosphate removement, purifying, etc. to prepare inositol. Alternatively, the recovered phytin is further subjected to the treatment of desalting, purfiying, etc. to prepare phytic acid.

Abstract: A method of refining animal and vegetable oils and fats comprising mixing said oils and fats with an alkaline solution, admixing the resulting mixture with an acid solution, separating insoluble matter from the admixture, and, if required, treating the admixture with conventional adsorption and steam distillation techniques.

Abstract: An immobilized glucose isomerase is obtained by mixing microbial cells of the microorganism having glucose isomerase activity with an aqueous solution of a natural water insoluble gel-forming substance. Glucose is isomerized to fructose by contacting an aqueous solution of glucose with said immobilized glucose isomerase more favorably than the usual isomerization method.

Abstract: The autoxidation resistance of an animal or vegetal fat or oil containing trace amounts of heavy metals which catalyze the autoxidation can be improved by contacting the fat or oil with solid citric, malic, or tartaric acid at a temperature below the melting point of the acid, and thereafter separating the acid particles from the fat or oil.
