Enzymatic Treatment of Soft Jackfruit (Artocarpus heterophyllus) Pulp With Two Commercial Pectinases: Physical Properties and Viscosity Analysis

The aim of this study was to investigate the effect enzyme hydrolysis jackfruit pulp using two commercial pectinase solutions with different polygalacturonase activities. A 2³ factorial design, three repetitions at central point, used establish optimal conditions hydrolysis, evaluating time (20 - 100 min), temperature (30 60ºC) and concentration (0.01 0.09%). dependent variables viscosity, yield, soluble solids content, color intensity, shade, turbidity were responses evaluated. Viscosity, pulps significantly influenced by all studied determination coefficients (R2) between 0.74 0.99. lack adjustment not significant in models that describe previous properties. highest (0.09%) factor greatest influence on responses, regardless type.
