Impact of Age on Sensorial Response of Sri Lankan Consumers on Biscuit Types

Sensory evaluation associates with the psychophysics behavior of the consumer. Hence, this research was conducted to study the effect of individual's age on the sensory profile such as appearance, odor, texture, taste and overall acceptance of five types of biscuits, namely crackers, semi-sweet biscuits, cream biscuits, savory biscuits and wafers. This relationship was assessed using a consumer panel consisting of 125 respondents, selected randomly by resorting ISO 5495:2005E sampling plan. Panelists were asked to rate the sensory attributes of the served biscuit samples over a fivepoint hedonic scale and collected data were statistically analyzed to determine whether there is a relationship between age and the sensorial response of the individuals. Results revealed that sensory stimuli taste, texture and overall acceptance were affected by the age of the respondent; however, appearance and odor were not significantly affected by the Age of respondents
