The study was performed to investigate the effect of corn bran as a fiber source on the utilization of thiamin niacin and pantothenic acid in human subjects for 8 weeks. Four different corn bran diets were fed : dry milled fine(DF) dry milled coarse(DC) wet milled fine(WF) and wet milled coarse(WC) Basal diet no corn bran bread added was employed as a control Apparent recovery of each B complex vitamin in urine was estimated to evaluate the vitamin and compared. The utilziation of three B vitamins was affected by the corn bran treatment. Dry milled corn bran had a higher recovery rate of thiamin(dry milled : 233% wet milled : 1.70%) than those receiving wet milled corn bran. Similar recovery pattern of niacin(dry milled : 1.94% wet milled : 1.50%) to that of thiamin was also observed. Particle size seemed to affect the vitamin utilization regardless of type of corn bran. Coarse bran gave a lower recovery value than fine corn bran in genreral. For pantothenic acid the recovery of the vitamin was affected to a greater extent by particle size of corn bran than by type of corn bran milling(fine: 60.22% coarse : 51.51%) Groups consuming wet milled corn bran\ulcorner(5`.57%) excreted more NDF than those fed dry milled corn bran(42.29%) Dry milled corn bran showed little or no water holding capacity poor fecal bulking properties and increased fecal transit time. The results suggest that corn bran supplementation exerts an negative effect on three B vitamin utilization.
