Process for preparing starch hydrolyzates with low DE by nanofiltration fractionating, products so obtained and use of these products

摘要

Manufacturing of a low-DE (dextrose equivalent) starch hydrolysate comprises fractionation of a starch hydrolysate with a DE of at least 18 using a nanofiltration membrane to produce a starch hydrolysate with a low DE (up to 25). The nanofiltration membrane is made of teflon, stainless steal, ceramic or polymer, and has a molecular weight fractionation of at least 4000 Daltons. Independent claims are also included for: (1) a starch hydrolysate with a DE of up to 25 and a polydispersity index of 5; (2) the manufacturing of an emulsion comprising the low-DE starch hydrolysate; (3) an emulsion comprising the low-DE starch hydrolysate and at least another ingredient; (4) the manufacturing of an encapsulated dry ingredient comprising: (a) producing a low-DE starch hydrolysate, preferably hydrogenated; (b) mixing the starch hydrolysate with at least one ingredient; and (c) drying the mixture; and (5) an encapsulated dry ingredient comprising at least one ingredient trapped in the amorphous matrix of the product.
