  • Patent number: 10899783
    Abstract: The present invention relates to a method for the chlorination of a sucrose-6-acylate to produce a 4,1?,6?-trichloro-4,1?,6?-trideoxy-galactosucrose-6-acylate wherein said method includes steps of: (i) combining the sucrose-6-acylate with a chlorinating agent in a reaction vehicle comprising a tertiary amide to afford a mixture; (ii) heating said mixture for a heating period in order to provide chlorination of sucrose-6-acylate at the 4,1? and 6? positions thereof; and (iii) quenching the product stream of (ii) to produce a 4,1?,6?-trichloro-4,1?,6?-trideoxy-galactosucrose-6-acylate; wherein before said quenching, a portion of said tertiary amide is removed by extraction into a solvent in which said tertiary amide is at least partially soluble.

  • Publication number: 20100074997
    Abstract: We disclose a composition comprising greater than about 95% d.s.b. of a starch comprising short chain amylose having an average degree of polymerization (DP) from about 20 to about 150, wherein an aqueous slurry comprising about 20% d.s.b. of the composition has a minimum yield stress of at least 400 Pa. We also disclose a method of preparing the composition comprising contacting a starch paste with a 4-?-glucanotransferase, to yield a chain-extended starch; contacting the chain-extended starch with a debranching enzyme, to yield a debranched starch; crystallizing the debranched starch, to yield a crystallized debranched starch; and shearing the crystallized debranched starch, to yield the composition. We also disclose a food formulation comprising a foodstuff and the composition.

  • Publication number: 20080286410
    Abstract: A process for producing a starch comprises treating a feed starch that comprises amylopectin with glucanotransferase to produce a chain-extended starch, treating the chain-extended starch with a debranching enzyme to produce a starch product that comprises amylose fragments, crystallizing at least part of the starch product, heating the starch product in the presence of moisture, treating the starch product with alpha-amylase, and washing the starch product to remove at least some non-crystallized starch. The product of this process has a relatively high total dietary fiber content.

  • Publication number: 20070089734
    Abstract: A process for producing an enzyme-resistant starch uses an aqueous feed composition that comprises (i) starch that contains at least about 50% by weight amylose, (ii) water, and (iii) alcohol. The concentration of starch in the feed composition is between about 5% and about 50% by weight, and the pH of the feed composition is between about 3.5 and about 6.5. In a first heating step, the feed composition is heated to a temperature between about 130-170° C. for about 0.1-3.0 hours. The feed composition is cooled to a temperature between about 4-70° C. for about 0.1-6.0 hours. In a second heating step, the feed composition is heated to a temperature between about 110-150° C. for about 0.1-10.0 hours. The starch is separated from the majority of the water and alcohol and is dried.
