Abstract
The objective of this research was to analysis of mass transfer in the process of osmotic drying Soursop fruit (Annona muricata). The research was conducted from February until April 2018 at Chemical Laboratory of Agricultural Product and Laboratory of Bioengineering, Department of Agricultural Engineering, Faculty of Agriculture, Sriwijaya University, Inderalaya. The research was done by using RAKF method (Group Randomized Design) with three treatment factors and three repetitions. The first factor was the size of material in pieces (A) which consisted of two levels, the thickness of 10 mm (A1) and the thickness of 5 mm (A2). The second factor was the medium temperature of osmosis (B) which consisted of two levels, medium temperature of 300C (B1) and medium temperature of 400C (B2), and the third factor was the comparison of salt and sugar compound (C) which consisted of three levels, sugar at 40% (C1), 50% (C2) and 60% (C3). Parameters observed were water losses, solid gain, water content, and total of dissolved solids. The result showed that the highest total of water losses during osmosis process had been occurred in A2B2C3 treatment at 73.30%, while the lowest had been occurred in A1B1C1 treatment at 34.76%. The highest total of solid gain during osmosis process had been occurred in A2B2C3 treatment at 34.48%, where as the lowest had been occurred in A1B1C1 treatment at 11.72%. Treatment A2B2C3 was the treatment that produced the lowest water content of material during the osmosis, at 44.68%, meanwhile treatment A1B1C1 produced the highest water content of material, at 71.73%. The highest water content after the material was heated in the oven was produced by A1B1C1 at 31.67%, while treatment A2B2C3 was the treatment that produced the lowest water content of material after it was heated in the oven, at 15.81%. Total dissolved solids of the material after osmosis and heating process on treatment A1B1C1 produced the lowest TPT at 26.07%, where as treatment A2B2C3 produced the highest TPT at 44.28%. Besides the research treatments, the level of solubility of material on medium and the age of the soursop also affected the rate of mass transfer on material.
