FLATULENCE FACTORS IN SWEET POTATO |
| Authors: | S.C.S. Tsou, M.H. Yang |
| Abstract:
Sweet potato starch and undigestable residual fractions were found to be major factors in flatulence induction in laboratory rats; no correlation was observed between free sugar fractions and flatulence. These results suggest that sweet potato flatulence is caused by a different group of compounds than flatulence caused by the ingestion of legume crops. Gas-formation induced by sweet potato was partially reduced by cooking. The induction of flatulence was found to be somewhat variety specific among sweet potato cultivars. A significant correlation coefficient between sweet potato starch content and hydrogen production was also observed. | |
