The processes were selected in such a way to use them in both at cottage level as well as in the scaled-up version for commercial production of wood apple juice. Initially, wood apple pulp was analysed for its physico-chemical properties. The wood apple pulp was given pre-treatments of 1) steaming at different time intervals (2, 4, 6 and 8 min) 2) pectinase enzyme treatment (incubation temperature: 35, 40, 45 °C; enzyme concentration: 10, 20, 30 mg/100 g; incubation time: 2, 4, 6 hrs) and 3) combined treatment (steaming and enzyme) at standardized conditions. The pre-treatments were standardized based on juice yield and TSS content in the juice. Once the pre-treatment was standardized, the wood apple pulp was then added with water in predefined ratio (2.5:1) and passed through various juice extraction machines such as basket centrifuge, fruit pulper, screw type juice extractor and hydraulic press.enFood Processing Technology, Bio EnergytechnologyThesis
