Sensory acceptance of mixed nectar of papaya, passion fruit and acerola

Abstract

Nectars are beverages formulated with the juice or pulp of one or more fruits, plus water and sugar in concentrations resulting in a "ready-to-drink" product. Recently, the market for such products has greatly expanded. Fruit mixtures present a series of advantages, such as the combination of different aromas and flavors and the sum of their nutritional components. The objective of this work was to develop a nectar based on papaya pulp and passion fruit juice, enriched with the vitamin C present in acerola pulp, optimizing the formulation using sensory consumer tests and a response surface statistical methodology. Eleven formulations were prepared using different concentrations of papaya pulp and passion fruit juice and sucrose, and maintaining the concentration of acerola pulp constant. The sensory tests were carried out with 22 nontrained panelists using a structured 9-point hedonic scale to evaluate overall acceptance. The acceptance means were submitted to regression analysis, by first calculating a polynomial quadratic equation. A predictive model was adjusted considering only those parameters where P ≤ 0.05, and a response surface was generated. The overall acceptance of nectars of different formulations varied from 5 ("neither liked nor disliked") to more than 7 ("liked moderately"), showing that some products can be considered adequate to consumers, like the nectar produced with 37.5% papaya pulp, 7.5% passion fruit juice, and 5.0% acerola pulp, added of 15% sucrose. A quadratic predictive overall acceptance model, with a regression coefficient of 0.97 was obtained. The sensory acceptance of nectars was positively affected by increases in the concentrations of papaya pulp and of sucrose. Thus, some products presented good sensory acceptance suggesting commercial potential.

Recentemente, o mercado para este produto de conveniência tem se expandido de forma expressiva. As misturas de frutas apresentam uma série de vantagens, como a combinação de diferentes aromas e sabores e a soma de componentes nutricionais. O objetivo deste trabalho foi desenvolver um néctar à base de polpa de mamão e suco de maracujá, fortificado com vitamina C presente na polpa de acerola, otimizando sua formulação através de testes sensoriais com consumidores e usando metodologia de análise estatística de superfície de resposta. Onze formulações foram elaboradas, empregando-se diferentes concentrações de polpa de mamão e de suco de maracujá e sacarose adicionada, mantendo-se constante a concentração de polpa de acerola. Os testes sensoriais foram realizados com 22 provadores não treinados, utilizando-se escala hedônica estruturada de nove pontos, para avaliação da aceitação global. As médias de aceitação foram submetidas a uma análise de r...

Atributos sensoriais e aceitação de sucos de uva comerciais

“…Sucos adoçados parecem ter a preferência do consumidor, conforme demonstrado por Matsuura et al (2004) no desenvolvimento de um néctar à base de polpa de mamão e suco de maracujá. A adição de açúcar à mistura de frutas diminuiu a acidez e influenciou positivamente a aceitação em até 17%.…”

Optimization of tropical fruit juice based on sensory and nutritional characteristics

“…In the beverage segment, a new market that is opening up is that of juice originating from mixed fruit (Matsuura et al, 2004). The development of mixed fruit juice or nectar is a resource available to the industry to develop unique drinks such as, for example, those with new flavors, improved color and consistency, and moreover, mixed-fruit juices are an alternative for adding nutritional value (Sobhana et al, 2015).…”

Sensory and nutritional evaluation of beverages developed using malted ragi (Eleusine coracana)

“…Jothi et al (2014) reported that mixed squash prepared from 40 percent carrot juice incorporation with 40 percent papaya and 20 percent banana juice was highly acceptable and indicated the commercial scope for developing nutritious squash from carrot, papaya and banana juice. Matsuura et al (2004) showed that nectar produced with 37.5 percent papaya pulp, 7.5 percent passion fruit juice and 5.0 percent acerola pulp with addition of 15 percent sucrose was highly acceptable. Papaya pulp and sucrose positively affect the sensory acceptance of nectars.…”
