Sensory Perception of Different Age Groups to Apple Juice
Shereen Gul, Mujeeb-ur-Rahman and Mohammad Zahoor-ul-Haq

Abstract: Sensory perception of 81 individuals of different age groups, adolescent (12-18 years), young adults (19-34), adults (35-49) and older adults (50-58 years) to apple juice was investigated. The subjects rated the juice for pleasantness, perceived sweetness, sourness and flavour intensity on a five points category scale. The studies showed that adolescent and older adults were less sensitive to sweetness of sucrose and had higher optimal sucrose concentration than other age groups. The slope for psychophysical function of sweetness decreased from adolescent to older adults. The slopes for sourness were somewhat flattened for young adults and adults than adolescent and older adults. The slopes of psychophysical function of apple flavour were not quite different for all the age groups.
