RESUMO

Currently, increasing importance is being given to the production of differentiated products within the fruit juice and drinks sector. The development of different juice and pulp blends is one resource available to industry for the preparation of differentiated beverages. The objective of this research was the development and sensory evaluation of a juice blend based on tamarind (Tamarindus indica) pulp and beetroot (Beta vulgaris) juice. A study was also carried out to determine the best processing conditions to extract the tamarind pulp. Thus various trials were carried out for the extraction of the tamarind pulp and the results indicated that a temperature of 50QC, maceration time of 20 min. and a fruit : water ratio of 1:1.5 produced a pulp with adequate physical, chemical and microbiological characteristics to be used as a raw material for the tamarind-beetroot blend. Tamarind pulp and beetroot juice were produced in amounts sufficient to formulate the 11 juice blends determined by the 22 complete, factorial, experimental design. These formulations were evaluated by a sensory acceptance test and buying intention using a 9 point non-structured hedonic scale. The results showed that the blend formulated with 35% tamarind pulp and 20% beetroot juice was the most accepted blend with the greatest buying intention. This blend was shown to be microbiologically, physically and chemically stable for 90 days of storage at room temperature
