Item Preference mapping to assess the effect of information on the acceptability of snack bars(Food Science and Technology, 2018) Pinto, Vinícius Rodrigues Arruda; Araújo, Lucas Guimarães; Soares, Letícia dos Santos; Dantas, Maria Inês de Souza; Souza, Thiago Duarte de; Melo, Laura Fernandes; Minim, Valéria Paula Rodrigues; Bressan, Josefina; Lucia, Suzana Maria DellaSix Brazilian commercial brands of snack bars were chosen to evaluate the importance of packaging, highlighting the potential of health claims on the acceptability of them. One hundred and two consumers evaluated bars in three sessions of acceptance test, using a nine-point hedonic scale: the first with no information about the product, the second containing the packaging of the product and the last with information on health-related claims associated with the consumption of the bar. A Randomized Complete Block Design structured the experiment. The results were analyzed using frequency distribution, internal preference mapping, ANOVA and Tukey test (p ≤ 0.05). In the blind test, the lower mean acceptance of the seed and protein bars showed the need for sensorial improvement. In the packaging test, the difference between the means show that the packaging of the bars evaluated did not differ on acceptance, differing only from the protein bar. Test with the information showed that information of health claims, for the most part, can positively influence sensory acceptance, even if in some cases there is no sensory pleasure.Item Influence of package and health-related claims on perception and sensory acceptability of snack bars(Food Research International, 2017-08-31) Pinto, Vinícius Rodrigues Arruda; Freitas, Tamara Beatriz de Oliveira; Dantas, Maria Inês de Souza; Lucia, Suzana Maria Della; Melo, Laura Fernandes; Minim, Valéria Paula Rodrigues; Bressan, JosefinaConcerns for health can lead to healthier food choices, especially if the consumer is well informed. This study aimed to evaluate the importance of package and health-related claims on Brazilian consumers' acceptance of snack bars. In order to evaluate package attributes, in focus groups discussions, 19 consumers chose the most important factors that influence their purchase decisions. Next, 102 consumers evaluated six commercial brands of snack bars in a three-session acceptance test: the first with no information about the product, the second containing the product package and the third with information on health-related claims associated with consumption of the bar. In general, package attributes, price and flavor were the most important factors that influence the purchase of snack bars. Health claims positively influenced consumer acceptance, but information concerning the absence of gluten and lactose did not significantly alter sensory acceptance. The presence of omega-3s, sugars, preservatives, flavorings and colorings have the potential to improve acceptability, because they were able to raise the acceptance of the seed bar, removing it from the rejection region. Protein and nut bars are not well known to the general public and the lower mean acceptance of the seed and protein bars demonstrated the need for sensorial improvement.
