Abstract
Official abstract text for this publication.
An enzymatically produced soluble α-glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble α-glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble α-glucan fiber are also provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of producing alpha-glucan, said method comprising: combining a food that has at least water and sucrose with a glucosyltransferase enzyme comprising an amino acid sequence that is at least 91% identical to SEQ ID NO: 10, wherein alpha-glucan comprising 100% alpha-1,6 glycosidic linkages is produced by the glucosyltransferase enzyme in the food and the method increases the amounts of soluble alpha-glucan and fructose in the food as measured. 2. The method of claim 1 , wherein the food is a liquid food product. 3. The method of claim 1 , wherein the food is a dairy product. 4. The method of claim 1 , wherein the food is a beverage. 5. The method of claim 4 , wherein the beverage is a carbonated beverage. 6. The method of claim 4 , wherein the beverage is a fruit juice. 7. The method of claim 4 , wherein the beverage is a concentrated juice. 8. The method of claim 4 , wherein the beverage is a milk-based drink. 9. The method of claim 1 , wherein the food is selected from the group consisting of yogurt, yogurt drinks, milk drinks, flavored milks, smoothies, ice cream, shakes, quarg, whipped mousse, fondants, nougats, soups, syrups, sauces, dressings, and coffee creamers. 10. The method of claim 1 , wherein the food is a bakery product. 11. The method of claim 1 , wherein the glucosyltransferase enzyme comprises an amino acid sequence that is at least 95% identical to SEQ ID NO:10. 12. The method of claim 1 , wherein the glucosyltransferase enzyme is immobilized on a support. 13. A method of producing alpha-glucan, said method comprising: combining a food that has at least water and sucrose with a glucosyltransferase enzyme comprising an amino acid sequence that is at least 90% identical to SEQ ID NO:43, wherein the food is a dairy product, carbonated beverage, fruit juice, bakery product, or is selected from the group consisting of yogurt, yogurt drinks, milk drinks, flavored milks, smoothies, ice cream, shakes, quarg, whipped mousse, fondants, nougats, soups, sauces, dressings, and coffee creamers, wherein alpha-glucan is produced by the glucosyltransferase enzyme in the food and the method increases the amounts of soluble alpha-glucan and fructose in the food as measured. 14. The method of claim 13 , wherein the glucosyltransferase enzyme comprises an amino acid sequence that is at least 95% identical to SEQ ID NO:43. 15. The method of claim 13 , wherein the glucosyltransferase enzyme is immobilized on a support. 16. The method of claim 13 , wherein the food is the dairy product. 17. The method of claim 13 , wherein the food is the carbonated beverage. 18. The method of claim 13 , wherein the food is the fruit juice. 19. The method of claim 13 , wherein the food is the bakery product. 20. The method of claim 13 , wherein the food is selected from the group consisting of yogurt, yogurt drinks, milk drinks, flavored milks, smoothies, ice cream, shakes, quarg, whipped mousse, fondants, nougats, soups, sauces, dressings, and coffee creamers.
