Abstract：
:Recent studies indicate that neonatal and adult rats are attracted to the taste of sugar as well as to starch-derived polysaccharides (e.g., Polycose). The present study investigated whether the relative preference for sweet and starchy tastes changes during the postweaning to adulthood period in male and female rats. This was accomplished by giving growing rats 24-hr/day one-solution (sucrose or Polycose vs. water) and two-solution (sucrose vs. Polycose) preference tests over a 9-week period (from 28 to 98 days of age). Acceptance (absolute intake) of sucrose and Polycose was also evaluated by comparing solution intakes during one-solution tests with water baseline intakes. Dilute solutions were used to minimize postingestive caloric and/or colligative effects. When tested with 2% saccharide solutions, the rats strongly preferred sucrose to Polycose with the preference increasing in magnitude from weeks 1 to 9 of testing. Sucrose acceptance also increased, relative to that of Polycose, after the third test week. When tested with 0.06 molar solutions, the rats initially consumed more Polycose (week 1) but by the fifth test week their sucrose preference and acceptance exceeded that of Polycose. These results indicate that the preference for sweet taste, relative to that for starchy taste, increases with age. Contrary to previous findings, the sweet taste preference was somewhat stronger in the male rats than in the female rats.
