Obtención de una base deshidratada a partir de pulpa de taxo (Passiflora mollisima) conservando carotenos y compuestos fenólicos.

Abstract

The present research had its main objective to obtain a dehydrated base from the pulp of a tropical fruit called taxo, optimizing conditions of spray-drying process in order to preserve bioactive materials and organoleptic characteristics. The Rapidasa Carrot cocktail showed the best results regarding diminishing of load of insoluble solids with a concentration 200 ppm. Moreover, it was observed an increment in the yield of pulp extraction of a 60,65 % up to a 75,86 %, and an addition in the quantity of soluble solids of 10,5 to 13 ºBrix. It was established the best conditions of spray drying: 12 mL/min of feeding flow and 3% of maltodextrin and it was obtained as a result a concentration of β-carotene and phenolic compounds: 12.4 ± 0.67 mg / 100g and 4121.47 mg ± 7.25 AG / 100g. The results show that the powder of the product is suitable for consumption and that preserve β-carotene bioactive materials (9,84 ± 0,45) and soluble phenolic compounds (4 102,92 ± 33,59), a useful life cycle was obtained, based on concentration of soluble soluble phenolic compounds, of 650 days in a (LDPE/FOILD/LDPE).
