Production of spray-dried honey jackfruit ( Artocarpus heterophyllus ) powder from enzymatic liquefied puree

Abstract

This paper presents the enzymatic liquefaction process for honey jackfruit optimized with Pectinex^® Ultra SP-L and Celluclast^® 1.5 L individually or in combinations at different concentrations (0–2.5% v/w) and incubation time (0–2.5 h). Treatment with combinations of enzymes showed a greater effect in the reduction of viscosity (83.9–98.8%) as compared to single enzyme treatment (64.8–87.3%). The best parameter for enzymatic liquefaction was obtained with 1.0% (v/w) Pectinex^® Ultra SP-L and 0.5% (v/w) Celluclast^® 1.5 L for 1.5 h. Spray drying process was carried out using different inlet temperatures (140–180 °C) and maltodextrin concentrations (10–30% w/w). Results indicated that the spray-dried honey jackfruit powder produced at 160 °C with 30% w/w maltodextrin gave the highest product yield (66.90%) with good powder qualities in terms of water activity, solubility, moisture content, hygroscopicity, color and bulk density. The spray-dried honey jackfruit powder could potentially be incorporated into various food products.
