Abstract
We evaluated the body energy accumulation as fat and protein from ingestion of difructose anhydride III (DFAIII). Male Wistar rats were fed 0, 0.25, 0.5, 1.0, or 1.5 g per d of sucrose or DFAIII added to a 7 g of basal diet for 20 d. Supplements of DFAIII did not increase whole body or peripheral fat or total body energy, whereas sucrose increased them in a dose-dependent manner. Dose-dependent increases in body water were observed in both groups. The body protein was influenced by the dose of sugars. The estimated available energy value of DFAIII was 0.263 kcal per gram; this value is one-fifteenth that of sucrose. Ingestion of DFAIII dose-dependently increased the cecal SCFA pool. DFAIII was not detected in feces, showing complete degradation of DFAIII in the intestine. These results indicate that DFAIII is a fermentable saccharide with quite low available energy for fat accumulation.
