Abstract
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.
Claims22
A method of producing alpha-glucan in a food product, said method comprising:
- combining a food product that has at least water and sucrose with a purified glucosyltransferase enzyme comprising an amino acid sequence that is at least 90% identical to SEQ ID NO:60, wherein alpha-glucan is produced by the glucosyltransferase enzyme in the food product, and a digestibility of less than 20% in the alpha-glucan is obtained as measured by Association of Analytical Communities (AOAC) method 2009.01.
