Osmotic dehydration of the I ndian fig ( O puntia ficus indica ) with binary and ternary solutions

Summary The objective of this work was to study osmotic dehydration ( OD ) of the I ndian fig with two binary solutions (sucrose/water and glucose/water) and a ternary solution (sucrose/ N a C l/water) according to a 2 3 factorial design with independent variables: temperature (30–50 °C), immersion...

Summary:Summary The objective of this work was to study osmotic dehydration ( OD ) of the I ndian fig with two binary solutions (sucrose/water and glucose/water) and a ternary solution (sucrose/ N a C l/water) according to a 2 3 factorial design with independent variables: temperature (30–50 °C), immersion time (90–240 min) and concentration (40–60 ° B rix). The dependent variables were water loss ( WL ), solid gain ( SG ) and dehydration efficiency index. The temperature had greater influence on the WL in the three hypertonic solutions studied; the concentration had greater influence on the SG in the three hypertonic solutions investigated and the best conditions for the OD of the I ndian fig were in glucose solution at 40 °Brix, 40 °C and 165 min.
