Melon cubes (2x2x2 cm) were immersed in glucose at the concentration of 40, 50 and 60°Brix for 0-5 hr. After the osmosis process for 5 hr, mass transfer parameters namely, water loss (WL) solid gain (SG) and weight reduction (WR), were evaluated. The result showed that concentrations of glucose affected mass transfer. The use of a 60°Brix glucose solution showed the highest (p<img title="\leq" src="https://latex.codecogs.com/gif.latex?\leq">0.05) water loss (21.81%), solid gain (5.31%) and weight reduction (16.44%). Thus, this sample had lower moisture content and higher total soluble solid content when compared with a fresh melon. The good qualities of melon were presented for all 3 concentrations solution was 5 hr. Then, the effect of the osmotic solution on the quality of the melon osmosis product was investigated. The melon which was immersed in 60°Brix glucose solution had the highest value in term of hardness as 27.20 N, lightness as 49.63 and total soluble solid as 34.20°Brix (p<img title="\leq" src="https://latex.codecogs.com/gif.latex?\leq">0.05) but the lower total color difference (<img title="\Delta" src="https://latex.codecogs.com/gif.latex?\Delta">E*) as 12.10, water activity (a<sub>w</sub>) as 0.899 and moisture content 76.34%wb than others.</p>}, number={2}, journal={Journal of Applied Research on Science and Technology (JARST)}, author={Parnsakhorn, Sunan and Langkapin, Jaturong and Phriknunchan, Supanut and Srichumpol, Artipat}, year={2020}, month={Oct.}, pages={132–143} }
