The objective of this work was to establish a technological procedure for producing a structured fruit product from yellow mobin and papaya purees, as an attempt to combine the sensory properties of both fruits and potentialize the functional properties of the final product. The effect of different combinations of pectin, gelatin and sodium alginate on the fruit gel properties was evaluated by response surface methodology. Papaya and yellow mobin purees and the structured products were characterized in terms of functional compounds (total tannin and carotenoid contents), as well as centesimal composition, pH, titratable acidity, soluble solids, sugars, water activity, carbohydrates and total energetic value. The results obtained from the experimental design indicated that only the gelatin concentration affected the product firmness. The developed fruit structured products presented good acceptance for all evaluated attributes. The data concerning purchase intent indicated that 70% of the panelists would probably or certainly purchase the mixed yellow mobin and papaya structured product if they found it for sale. |
