| Description |
Use of osmotic drying for removal of coconut kernel from the shell as a step in the production of dried whole coconut milk was assessed. Effects of temp. (25-45C) and concn. (40-70Brix) of the osmotic agent (sucrose) on the osmotic drying procedure were also studied. Water loss from the coconut samples increased with increasing temp. and concn. of the osmotic solution. An equation was proposed for the reduced wt. based on Fickian diffusion as a function of temp., concn., and immersion time. Pseudo diffusion coeff. of water in the coconut samples were calculated based on the proposed equation. High correlation was observed between predicted and experimental values. It is concluded that osmotic drying could be a useful upstream step in coconut processing.
