The temperature of incubation (30–60 C), time of reaction (20–120 min) and concentration of pectinase
(0.01–0.05% v/w) were the independent variables and viscosity, clarity, alcohol insoluble solids (AIS),
total polyphenol and protein concentration were the responses. Total soluble sugar, pH, conductivity,
calcium, sodium and potassium concentration in the juice were also evaluated
