Abstract:

The effect of steaming, enzymatic action and combined treatments as pre-treatments as well as different juice extraction machines on juice yield and total soluble solids of wood apple (Feronia Limonia) juice was studied. Pretreatments i.e. steaming for 2, 4, 6 and 8 minutes and enzymatic treatment (pectinase and cellulase enzyme) at different concentration (10, 20 and 30 mg/100g), incubation time (2, 4 and 6 hrs) and incubation temperature i.e. 40oC and combined enzymatic treatments of pectinase and cellulase enzymes in different proportions (3:7, 5:5 and 7:3)as well as combined optimized treatments (steaming and enzymatic treatments) followed by three juice extraction machines i.e. basket centrifuge, screw type juice extractor and fruit pulper at different rpm were studied and evaluated for juice recovery (%) and total soluble solid (TSS) content of juice from wood apple fruit pulp. Combined optimized pretreatment i.e. 6 min of steaming, combination of pectinase and cellulase (7:3), 30 mg/100g combined enzyme concentration, 6 hrs of incubation time at 40oC incubation temperature obtained maximum juice recovery (82.85%) and TSS content (5.3oBx) of juice from wood apple pulp. The Screw type juice extractor obtained highest juice recovery (86.9%) and TSS (5.6°Bx) at 150 rpm followed by basket centrifuge and fruit pulper. The data was statistically analyzed by using completely randomized design (CRD).
