Title:

PRODUCTION OF LOW-DE STARCH HYDROLYZATE BY NANO- FILTRATION FRACTIONATION, PRODUCT OBTAINED THEREBY, AND USE OF SUCH PRODUCT

Document Type and Number:

Japanese Patent JP2000001502

Kind Code:

A

Abstract:

To obtain a stable low-DE starch hydrolyzate having an improved loading capacity by fractionating a low-DE starch hydrolyzate having a specified DE (content of dextrose, etc.), with a nano-permeable membrane having a specified fractionation molecular weight under nano-permeation conditions effective for the formation of the low-DE starch hydrolyzate.

A starch hydrolyzate having a DE larger than about 18 is fractionated with a nano-permeable membrane selected among a teflon membrane, a stainless steel membrane, a ceramic membrane, and a polymer membrane and/or having a fractionation molecular weight of below 4,000 Da under nano- permeation conditions effective for the formation of the low-DE starch hydrolyzate. The nano-permeable membrane is desirably a polyamide membrane or a polysulfonated polysulfone membrane having a fractionation molecular weight of about 400 to 4,000 and is desirably a composite membrane selected from a polyamide membrane and a polysulfonated polysulfone membrane.
