CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior === Prebiotic beverages made from cashew nut kernels and fruit juice are a viable alternative in the area of new functional productsâ development. Thus, this research aimed to develop three prebiotic beverages made from cashew nut kernels added with fruit juice (grape, mango and pineapple), evaluating how non-sensory attributes (external to the product) and consumersâ characteristics as to behavior and personality affect their acceptance. A factorial 2 central composite rotatable design was used for the development of the formulations. Focus groups were applied to define the most important label attributes on consumerâs purchasing decision. The illustration, nutritional information and the term prebiotic associated with its functional claim, within their respective levels, were selected for the labelsâ development via the 3x2x3 full factorial design and the employment of conjoint analysis and cluster analysis multi-varying techniques for results evaluation. The mango beverage was evaluated displaying three different label versions in order to check if the expectation generated by different nutritional information affected consumersâ perception as to characteristics of quality, overall impression and purchasing attitude. The beverage added with pineapple juice was compared to its soy-based commercially similar in order to evaluate if information on composition, nutritional characteristics and functional claims associated with these products affect the acceptance and perception of consumers with different behavioral characteristics and personality. The formulations optimized as to acceptance should be added with the following concentrations of sugar and juice, respectively; grape beverage (37% and 7%), pineapple (35% and 7%) and mango (40% and 8%). Among the most important label attributes in the purchasing process, the illustration was the one that mostly influenced, followed by nutritional information and the term prebiotic and its functional claim. The nutritional claims displayed on the label revealed to have a positive impact over the perception of the beverage as to the characteristics of quality, overall impression and purchasing attitude, with information such as â0% lactose, 0% cholesterol and fiber-richâ and â0% lactose, 0% cholesterol and antioxidantsâ found to influence more positively consumers. Information related to the beverages made from soy and cashew nut did not influence the acceptance of flavor nor on the overall impression, nonetheless, it had a positive impact over consumersâ perception as to healthiness and the nutritious value of both, being the cashew nut kernel-based beverage perceived as more nutritious and healthier than the soy-based one. Consumersâ different characteristics as to the interest in healthy eating and food neophobia did not influence the acceptance of the beverages, their perception as healthy food and nutritious value. === Bebida prebiÃticas à base de amÃndoas de castanha de caju e suco de frutas à uma alternativa viÃvel na Ãrea de desenvolvimento de novos produtos funcionais. Assim, este trabalho objetivou desenvolver trÃs bebidas prebiÃticas à base de amÃndoa da castanha de caju adicionadas de suco de frutas (uva, manga e abacaxi), avaliando de que forma atributos nÃo sensoriais (externos ao produto) e caracterÃsticas comportamentais e de personalidade dos consumidores afetam a sua aceitaÃÃo. Utilizou-se um delineamento fatorial 22 do tipo composto central rotacionado para desenvolvimento das formulaÃÃes. Grupos de foco foram empregados para definiÃÃo dos atributos do rÃtulo mais importantes na decisÃo de compra do consumidor. A ilustraÃÃo, as informaÃÃes nutricionais e o termo prebiÃtico associado a sua alegaÃÃo funcional, com seus respectivos nÃveis, foram selecionados para o desenvolvimento dos rÃtulos por meio de delineamento fatorial completo do tipo 3 x 2 x 3, aplicando-se as tÃcnicas multivariadas conjoint analysis e cluster analysis para avaliaÃÃo dos resultados. A bebida de manga foi avaliada associada a trÃs versÃes do rÃtulo para verificar se a expectativa gerada por diferentes informaÃÃes nutricionais afetavam a percepÃÃo dos consumidores quanto Ãs caracterÃsticas de qualidade, impressÃo global e atitude de compra. A bebida adicionada de suco de abacaxi foi comparada frente ao seu similar comercial à base de soja para avaliar se informaÃÃes sobre composiÃÃo, caracterÃsticas nutricionais e alegaÃÃes funcionais associadas a estes produtos afetam a aceitaÃÃo e percepÃÃo dos consumidores com diferentes caracterÃsticas comportamentais e de personalidade. As formulaÃÃes otimizadas quanto à aceitaÃÃo devem ser adicionadas das seguintes concentraÃÃes de suco e aÃÃcar, respectivamente, para a bebida de uva (37% e 7%), abacaxi (35% e 7%) e manga (40% e 8%). Dentre os atributos do rÃtulo mais importantes no processo de compra, a ilustraÃÃo foi o que mais influenciou, seguido pelas informaÃÃes nutricionais e pelo termo prebiÃtico e sua alegaÃÃo funcional. As alegaÃÃes nutricionais no rÃtulo mostraram ter um impacto positivo na percepÃÃo da bebida quanto Ãs caracterÃsticas de qualidade, impressÃo global e atitude de compra, com os as informaÃÃes â0% lactose, 0% colesterol e fonte de fibrasâ e â0% lactose, 0% colesterol e antioxidantesâ influenciando mais positivamente os consumidores As informaÃÃes relacionadas Ãs bebidas de soja e castanha de caju nÃo influenciaram a aceitaÃÃo do sabor e impressÃo global, no entanto tiveram um impacto positivo na percepÃÃo dos consumidores quanto à saudabilidade e o valor nutritivo de ambas, sendo a bebida à base de amÃndoa da castanha de caju percebida como mais nutritiva e mais saudÃvel do que a bebida de soja. As diferentes caracterÃsticas dos consumidores quanto ao interesse em alimentaÃÃo saudÃvel e a neofobia alimentar nÃo tiveram influÃncia sobre a aceitaÃÃo das bebidas, a percepÃÃo de alimento saudÃvel e valor nutritivo. |
