Abstract
O presente trabalho teve como objetivo elaborar tres bebidas mistas a base de caja (Spondias mombin L.) e caju (Anacardium occidentale), na forma "pronto para beber", com propriedades prebioticas e avaliar as suas caracteristicas quimicas, fisico-quimicas e sensoriais. Foram desenvolvidas quatro formulacoes com duas combinacoes de polpa de fruta, sacarose e ingredientes prebioticos (inulina padrao, inulina de alto desempenho- HP e frutooligossacarideos- FOS). As formulacoes foram submetidas as determinacoes de pH, acidez, solidos soluveis, acucares, acido ascorbico, carotenoides totais e polifenois totais e avaliacoes da aceitacao dos atributos sensoriais, corpo, docura e impressao global, atitude de compra e preferencia dos consumidores. Verificou-se que o pH (3,19 a 3,40), solidos soluveis totais (14,80 a 15,40 oBrix) e polifenois totais (24,76 a 34,58mg/100g) apresentaram diferenca estatistica significativa (p .0,01). Enquanto para os teores de acidez total (0,48 a 0,56 mg/100g), acucares totais (7,78 a 9,84%), acucares redutores (1,62 a 2,08%), acucares nao redutores (5,86 a 7,85%), acido ascorbico (33,43 a 35,17 mg/100g) e carotenoides totais (30,30 a 34,20 mg/100g), nao se observou diferenca significativa. Os atributos sensoriais avaliados apresentaram resultados variando na escala sensorial entre "nao gostei nem desgostei" e "gostei muito" (medias de 5,80 a 7,06). Nos atributos docura, corpo e atitude de compra nao houve diferenca (p>0,05) entre as bebidas, porem, diferiram estatisticamente (p.0,05) no atributo impressao global. A bebida com FOS apresentou uma aceitacao semelhante a bebida controle, mostrando ser uma opcao de alimento funcional atendendo as expectativas dos consumidores, que buscam alimentos saudaveis, nutritivos e saborosos.The purpose of this work was to develop three mixed drinks based on caja (Spondias mombin L.) and cashew apple (Anacardium occidentale) pulps, added prebiotic ingredients and to evaluate their chemical, physicochemical and sensory properties. Four formulations with combinations of two pulp fruit, sucrose and prebiotic ingredients (Standard inulin, inulin high performance-HP-and fructooligosaccharides FOS) were developed. The mixed drinks were submitted the following analysis pH, acidity, soluble solids, sugars, ascorbic acid, total carotenoids, total polyphenols and acceptance ratings of the sensory attributes such as: consistency, sweetness and overall impression, attitude and consumers purchase preference. The pH, total soluble solids and polyphenol results showed difference (p . 0.01) significant, while for the analysis of total acidity, sugars, ascorbic acid and carotenoids, it was not observed significant difference. The sensory attributes evaluates showed results ranging in scale between "I did not like or disliked "and" liked "(average 5.80 to 7.06). The attributes sweetness, consistency and attitude of buying showed no difference (p> 0.05) between drinks, however, differed significantly (p . 0.05) for the attribute of overall impression. The drink with FOS showed a similar acceptance when compared to traditional (sucrose) drink, showing an option of meeting the functional food expectations of consumers, who seek healthy, nutritious and tasty foods.
