Nondigestibility of a new sweetener, "Neosugar," in the rat

Nondigestibility of a new sweetener, "Neosugar," in the rat. Oku, Tsuneyuki; Tokunaga, Takahisa; Hosoya, Norimasa (Fac. Med., Univ. Tokyo, Tokyo 113, Japan). J. Nutr., 114(9), 1574-81 (English) 1984. CODEN: JONUAI. ISSN: 0022-3166. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) The digestion of Neosugar [88385-81-3], a mixt. of 1F-(1-b-fructofuranosyl)n-1 sucrose [ n = 2, 1-kestose (GF2) [470-69-9]; n = 3, nystose (GF3) [13133-07-8]; n = 4, 1F-b-fructofuranosyl nystose (GF4)] [59432-60-9] was investigated in vitro and in vivo in the rat. GF2 and GF3 were not hydrolyzed by a pancreatic homogenate. The GF2- and GF3-hydrolyzing activities of the enzymes in the intestinal mucosa homogenate were negligible compared with the activities of maltase and sucrase. GF2 and GF3 added to the incubation mixt. did not affect the activities of sucrase and maltase in the intestinal mucosa. Long-term ingestion of Neosugar did not cause induction or suppression of GF2- and GF3-hydrolyzing enzymes in the small intestine. [U-14C]Neosugar injected i.v. was rapidly excreted in the urine without having undergone any degrdn. Apparently Neosugar, which consists of GF2, GF3, and GF4, is scarcely hydrolyzed by the digestive enzymes of the gastrointestinal tract and internal organs, and is probably not utilized as an energy source in the body.
