Gustatory responses of pigs to various natural and artificial compounds known to be sweet in man

摘要

The gustatory preferences in pigs towards 33 compounds known to be sweet in humans were evaluated through a specific twchoice preference method. All the 14 carbohydrates tested are preferred over water, sucrose being the most effective. Sucrose and fructose response intensities are identical in pigs and humans but lactose, maltose, D-glucose and D-galactose are twe times less efficient in pigs. The molar order of effectiveness is sucrose > D-fructos > maltose=lactose > D-glucose > D-galactose, roughly similar to humans.
