Abstract
The effect of coating blanched pumpkin cubes with sodium alginate (SA) on water loss (WL) solid gain (SG) physicochemical qualities and cell structure of osmotic dehydrated (OD) pumpkin was studied. Pumpkin samples coated with 1.0 0.02 3.0 SA (w/w) and samples without coating (control) were immersed in 70 (w/w) sucrose solution with a ratio of solution to sample of 4:1 for 12 h. The results showed that WL hardness and reducing sugar of coated samples at the equilibrium point were higher than those of samples without coating significantly (p 0.05) while water activity moisture content SG and total sugar of coated samples were less than samples without coating significantly (p0.05). Coating with 3.0 SA gave the highest process efficiency index (WL/SG) of 5.28.
