| Summary: | 碩士 === 國立中興大學 === 食品暨應用生物科技學系所 === 104 === In this study, a dietary fiber formula mixture was prepared with resistance maltodextrin and inulin and its effects on fecal short chain fatty acid profiles of rat fed high fat diet and normal diet was investigated. Rats were fed on high fat diet containing 23% fat to induced obesity. The dosage of dietary fiber formula was based on some related studies and certified health foods. Low dose (3.5 g of resistance maltodextrin and 2.5 g of inulin) and high dose (7 g resistance of maltodextrin and 5 g of inulin) were prepared. Rats were divided into 6 groups, namely, normal diet group (NC), normal diet with low dose group (LNC), normal diet with high dose group (HNC), high fat diet group (HF), high fat diet with low dose group (LHF), and high fat diet with high dose group (HHF). The results showed that the consumption of high dosage sample could significantly (p < 0.05) reduce fecal pH value in both diets. Feeding HNC diet significantly (p < 0.05) increase fecal moisture. There were no differences between the control and high dose groups in both diets. Fecal short chain fatty acid were significantly (p < 0.05) increased by taking high dose of fiber samples in both diets.
It was concluded that the consumption of these dietary fiber formulas periodically in a long term could increase fecal output and short chain fatty acid, and hence help improve gut health.
