title: Hedonic response of rats to polysaccharide and sugar solutions.
abstract: The palatability of glucose, sucrose, maltose and polysaccharide (Polycose) was assessed by examining the consummatory response of nondeprived female rats to equicaloric or equimolar solutions of these saccharides. Both 30-min one-bottle acceptance and 30-min two-bottle preference tests were conducted: initial (3-min) lick rates were also recorded. At low molar concentrations the relative palatability of the saccharides was ordered as follows: Polycose greater than maltose greater than sucrose greater than glucose. At higher concentrations the rats were more attracted to sucrose than to Polycose; however Polycose remained more palatable than maltose at all but the highest concentration. In the one-bottle tests gram solute intakes varied as a function of percentage concentration, and was not influenced by saccharide type or solution osmolarity. The results along with other recent findings indicate that rats can taste starch-derived polysaccharides and find them quite palatable.
