  • Patent number: 4445938
    Abstract: This invention relates to a starch hydrolysate which can be optionally hydrogenated as well as the process for preparing said hydrolysate and uses thereof.Its glucidic spectrum corresponds to:a content of monosaccharides (DP=1) less than 14%,a content of disaccharides (DP=2) less than 35%, preferably less than 20%,a content of oligosaccharides of DP 4 to DP 10 ranging from 42% to 70%, preferably from 42 to 60%, the oligosaccharides of DP 5 to DP 7 representing by themselves a proportion preferably higher than 25% and more preferably higher than 30%,a content of polysaccharides of DP higher than 10, less than 32%, and preferably less than 25%.The hydrolysate is useful in the preparation notably of human foodstuff.

  • Patent number: 4346116
    Abstract: The invention relates to a non-cariogenic hydrogenated starch hydrolysate as well as to a process for preparing it.The starch hydrolysate according to the invention comprises:less than 3% by weight of polyols of DP higher than 20;less than 60% by weight of maltitol (DP 2);less than 19% by weight of sorbitol (DP 1), the balance to 100 being constituted by polyols of DP 3 to 20.This starch hydrolysate can be used in food products as a sweetening non-cariogenic agent.
    Type: Grant
    Filed: May 21, 1980
    Date of Patent: August 24, 1982

  • Patent number: 4279931
    Abstract: The invention relates to a non-cariogenic hydrogenated starch for confectionery and process for preparing this hydrolysate. This hydrogenated starch hydrolysate comprises a content of polyols of DP higher than 20 which is sufficiently low for the cariogenic character of these polyols not to be troublesome and a content of low molecular weight products, which is sufficiently low for their presence not to interfere with the applicability of said hydrolysates in confectionery. The hydrogenated starch hydrolysate can be used in the manufacture of "hard candies" and chewing gums.
