Abstract: A method and apparatus for separation of an extract component from a raffinate component in a simulated moving bed chromatographic separation train system. The system includes a plurality of beds, packed with a sorbent material, connected to form a closed recycle loop. Inlets to the train are provided for a feed stream and a desorbent stream along with outlets for removal of a raffinate stream and an extract stream. Increased product throughput and yield are obtained by intermittantly introducing and withdrawing the various streams to the train while continuously recycling a portion of the fluid in the system.

Abstract: The invention is a process for preparing a glycoside product by reacting an alcohol having 4 to 30 carbon atoms with a saccharide or oligosaccharide in the presence of an acid catalyst wherein an undissolved phase comprising the saccharide or oligosaccharide is present in the reaction mixture during the process.

Abstract: A solvent extraction and desolventizing process is disclosed which removes substantially all flavor-bearing substances from a moist vegetable protein concentrate, provides a nitrogen solubility index (NSI) of about 6-15, a Bostwick flow value of less than 10, a water absorbency of the concentrate in the range of 270-350, and a penetrometer reading in the range of 7-30 mm so that said vegetable protein concentrate may be used as a protein-containing ingredient in prepared meats.The process includes extracting defatted vegetable protein flakes with an aqueous alcohol solution to remove soluble carbohydrates and flavors, leaving an extracted product having a moisture and volatiles content of about 50-70% by weight. The alcohol-extracted product which contains about 20-40% by weight water, is thereafter desolventized in a humid gas atmosphere with a relatively low gas temperature of less than about 260.degree. F. (127.degree. C.) for about 1-6 hours.
