Genotoxicity and 28-day oral toxicity studies of a functional food mixture containing maltodextrin, white kidney bean extract, mulberry leaf extract, and niacin-bound chromium complex
Steady-fiber granule (SFG) is a functional food mixture that is composed of four major ingredients, resistant maltodextrin, white kidney bean (Phaseolus vulgaris) extract, mulberry leaf (Morus alba L.) extract, and niacin-bound chromium complex. This study focused on determining the safety of SFG. Genotoxicity and 28-day oral toxicity were evaluated. SFG did not induce mutagenicity in the bacterial reverse mutation assay using five Salmonella typhimurium strains (TA98, TA100, TA102, TA1535, and TA1537) in the presence or absence of metabolic activation (S9 system). SFG also did not induce clastogenic effects in Chinese hamster ovary cells with or without S9 treatment. Similarly, SFG did not induce genotoxicity in a micronucleus test conducted with mice. A dose-dependent 28-day oral toxicity assessment of SFG for rats revealed no significant effects on mortality, body weight, selected organ weights, and behavior. Evaluations of hematology, clinical biochemistry, and histopathology showed no adverse effects in rats treated with SFG. These results suggest that SFG has no significant mutagenic or toxic properties, and the no observed adverse effect level of SFG was defined as at least 5000 mg/kg/day orally for 28 days for male and female rats.
