Patent number: 4332622Abstract: This invention provides a method for the purification of cane juice to produce a finished product of very high quality. This purification process and general concept differs from existing cane juice purification schemes in that traditional methods either produce crystalline raw sugar or a liquid product commonly referred to as high test or fancy molasses. The processing of the cane juice generally comprises the steps of:(a) pretreating the cane juice to remove any soil or foreign matter and substantially reducing the total cation concentration of the cane juice;(b) hydrolyzing the pretreated cane juice to a desired degree;(c) purifying the hydrolyzed juice without precipitation or crystallization of raw sugar by subjecting the solution obtained in step (b) to gross demineralization and decolorization; and(d) concentrating the purified solution obtained in step (c) to obtain a pure odorless finished sugar product which meets or exceeds existing standards for pure sugar.Type: GrantFiled: August 25, 1980Date of Patent: June 1, 1982Assignee: Savannah Foods & Industries, Inc.Inventors: Otto G.

Patent number: 4263052Abstract: A process for obtaining fructose solutions or solid fructose, a raw material containing sucrose and/or similar fructofuranosides is hydrolyzed to fructose and glucose and treated with a calcium base (e.g. calcium oxide or hydroxide) to precipitate calcium-sugar complexes. The precipitate is slurried in water and then treated with phosphoric acid to liberate (e.g. at a pH of 5.5 to 9) a fructose solution of high purity (i.e. de-complex the calcium-fructose complex), with precipitation of useful calcium phosphate salts. Phosphoric acid has been found to have significant advantages over carbonic acid or carbon dioxide as the fructose-liberating (de-complexing) agent, e.g. better yields and more useful by-products. Solid fructose can be obtained from the fructose solution in a known manner. The filtrate from the calcium-sugar complexing step can be acidified to yield stable, useful, fructose-depleted by-products.Type: GrantFiled: October 12, 1979Date of Patent: April 21, 1981Assignee: American Crystal Sugar CompanyInventors: Stanley E.

Process for the simultaneous production of fructose and gluconic acid from glucose-fructose mixtures
Patent number: 4242145Abstract: A process for the simultaneous production of fructose and of gluconic acid from glucose-fructose mixtures and/or from invert sugar by the selective oxidation of the glucose proportion, wherein oxygen and/or air, activated by noble metal catalysts, are utilized as the oxidizing agents; the oxidation is conducted in a pH range of about 8 to 10; and the oxidation is terminated after the formation of 1 equivalent of carboxylic acid per mole of glucose employed.The thus-obtained gluconic acid can subsequently be separated from the unchanged fructose in a simple way and practically quantitatively, and can be isolated as the salt.Type: GrantFiled: February 21, 1979Date of Patent: December 30, 1980Assignee: Merck Patent Gesellschaft mit beschrankter HaftungInventors: Hans-Rudolf Muller, Werner Kundig, Alfred Hedinger -
Patent number: 4196017Abstract: A method for reducing color impurities in sugar-containing syrups. First, hydrogen peroxide is added to the syrup and mixed with it. Following that, a suitable cationic surfactant is added, ahd there is further mixing. After that, a suitable defecant is added, such as a mixture of calcium chloride and sodium carbonate, which react with each other to form calcium carbonate in the sugar solution. Activated vegetable carbon and diatomaceous earth are added and mixed. Then the solids are filtered out to obtain a purified sugar solution which may be used directly or may be inverted, as by conventional acid treatment, and then used.Type: GrantFiled: January 29, 1979Date of Patent: April 1, 1980Assignee: Holly Sugar CorporationInventors: James C.
