  • Patent number: 5270177
    Abstract: The invention relates to the field of nutrition and the sugar industry and presents a method and apparatus for producing glucose-fructose liquors on an industrial scale from sugar or liquors thereof. The invention uses reactors packed with a catalyst with high hydrolytic activity, and these are installed within a sugar refining factory or in an industry which dissolves it, such that glucose-fructose syrup is produced in a single operation by a continuous flow of the sugar liquor. High levels of hydrolysis may be attained by modification of the residence time. The process of hydrolysis of the sugar does not significantly alter the color of the solution. The product obtained on an industrial scale can be used both in the food industry and in the pharmaceutical industry.

  • Patent number: 4547226
    Abstract: The sugar content of citrus press liquor is enhanced by separating citrus solids, extracting fructose, glucose, and sucrose from the solids, and recombining the aqueous extract to increase the sugar content thereof. By inversion of the sucrose present in the sugar-enhanced press liquor, a high fructose syrup can be readily obtained which is indistinguishable from high fructose corn syrup. When separation is effected by centrifugation, a biocidally active colloidal phase is formed from which citrus terpenes and limonene can be extracted, resulting in a press liquor suitable for fermentation. The solid residue remaining after extraction can also be recycled with the remaining press cake.

  • Patent number: 4332622
    Abstract: 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.

  • Patent number: 4263052
    Abstract: 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.

    Abstract: 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.
