Analysis of the Impact of Age and Gender for the Differential Threshold Level and Discrimination Power on Gustation Moda

Discrimination power of consumer, which is known as the differential threshold level is an important dimension in product development and marketing activities of the sector of food science. This study examined the effect of demographic factors age and gender for differential threshold level on two gustation modalities, salt and sugar. Study was conducted according to the ISO5495 2005 E pared comparison for standard salt and sugar samples respect to three reference samples using 180 selected respondents. Each respondent were gone through 15 comparison for each tastant, besides responds were collected through a questionnaire and analyzed by SPSS 22.0 statistical software under the significance level of 0.05. Results showed differential threshold level has no linear correlation P 0.050 with age and gender for both gustations, but younger ages and female gender shows higher discrimination ability than older ages and gender male. Discrimination between salt concentrations was easier than on behalf of sugar taste for both genders, but females showed a higher discrimination power than males. Abeywickrema S. | Gunathunga C.
