  • Linear and cyclic sucrose reaction products, their preparation and their use
    Patent number: 5882420
    Abstract: Sucrose ester and ether products, useful as food or beverage bulking agents, reduced calorie sweeteners, fat replacement agents, stabilizing agents, thickening agents and emulsifying agents; adhesives; biodegradable plastics and films; sizing agents for paper and textiles; ethical pharmaceuticals and new fibers are prepared by using a two-phase reaction system in which sucrose is dissolved in an alkaline, aqueous solution and an acidic reagent such as a bifunctional acid dichloride or epoxide is added to the sucrose in a water-immiscible organic solvent. Several types of products are produced: water-insoluble sucrose ester (ether) copolymers; water-soluble sucrose ester (ether) copolymers; sucrose ester (ether) dimers; and intramolecular, cyclic sucrose esters (ethers). These products can be further varied by using different kinds of acid dichlorides or epoxides that contain different kinds of functional groups.

  • Process for preparing high purity lactose
    Patent number: 4099983
    Abstract: Lactose crystals of improved purity and reduced color are obtained by washing the lactose crystals in an alkaline wash-bath having a pH within the range of from about 8.5 to about 12.5. The isolated washed crystals exhibit improved purity particularly in the reduction of nitrogen-containing impurities as evidenced by a reduced total Kjeldahl nitrogen content and a substantially white color.
