Abstract

Osmotic dehydration kinetics of Terung Asam (Solanum lasiocarpum Dunal) under different process temperature (35-55 C) sucrose concentration (40-60) and immersion time (30-180 min) were studied. Results obtained indicated that water loss (WL) increased with sucrose concentration and temperature. Similarly solid gain (SG) also increased with temperature elevation. The effective diffusivities calculated using Ficks model were in the range of 7.7678 x 10-10 to 11.6519 x 10-10 m s- for WL and 3.5462 x 10-10 to 8.1056 x 10-10 m s- for SG. Meanwhile the activation energy for moisture diffusion varied from 4.900 to 7.423 kJmol- and for solid diffusion from 10.440 to 14.323 kJmol-.
