Abstract

The serving size and gender effects on product acceptance and ideal attribute (lemonade flavor, sourness and sweetness) ratings of lemonade were investigated using a 15-point hedonic scale and a 5-point just-right scale, respectively. Females (67) and males (68) consumed a 4 oz (118 ml) sample ad libitum, or a full 8 oz (236 ml) serving. Ad libitum male consumption was not different (p>0.05) from female consumption. A low correlation (R2=0.011) was observed between the amount of lemonade consumed and product acceptability or just-right attribute ratings. Neither serving size nor gender had an effect on the overall acceptability (p>0.05). However, the interaction of gender and serving size affected the overall acceptability (p≤0.05) and sweetness (p≤0.10). Male acceptability scores were lower (p≤0.05) than female scores under ad libitum conditions. Male acceptability scores increased (p≤0.05) with increased sample size. There was no significant difference observed for lemonade flavor, sourness or sweetness just-right ideal scores as the sample size increased (p>0.05). A higher proportion of males rated the sweetness just-about-right as compared to females (p≤0.05). This study showed that consumption of a standard serving size did not result in sensory specific satiety, but several interesting gender effects were found.
