  • Patent number: 6942997
    Abstract: An enzymatic system comprised of glucose oxidase and a catalase of the same or different sources to result in the complete conversion of glucose to gluconic acid at a glucose concentration greater than 25% (w/w) ds. The resultant gluconic acid, which is essentially free from impurities normally associated with the fermentation process, is then spray granulated to produce a low-dust dry product.

  • Publication number: 20030134396
    Abstract: An alpha-amylase enzyme obtained from Bacillus acidocaldarius species is utilized to liquefy starch at a pH as low as 3.0 without the need to add thermostabilizing agents such as calcium. The alpha-amylase produces acceptable DE yields in a single liquefaction step and does not need to be inactivated prior to conducting saccharification which can proceed without adjustment of the pH of the liquefact. Alternatively, a secondary liquefaction process can be utilized, in which case two additions of the alpha-amylase are used resulting in a combined low dosage of the enzyme.

  • Patent number: 5759984
    Abstract: Methods for stabilizing enzymes in liquid compositions, including those liquid compositions having a high water content and those stabilized enzyme liquid compositions formed thereby. The method involves forming the enzyme, so that it is in an insoluble form thereof and then adding thereto an agent for maintaining the enzyme in the insoluble form thereof. Examples of such insoluble forms are crystal forms of the enzyme. Enzymes which are stabilized in this manner are useful for combining with liquid compositions, including liquid compositions having a high water content. The method is particularly useful for the preparation of stable enzyme-containing liquid detergent compositions.
