Abstract
The use of edible coatings is a suitable method to reduce oil uptake in fried foods. In this research, the effects of propolis gum on the physicochemical properties of fried potato strip were evaluated.
 The propolis coating was performed at three concentrations 1%, 1.5%, 2% w/v. Potato strips were dipped in the coating solutions followed by air drying. Viscosity of coating was measured in two shear rate 0.048 and 62.11 1/s. The treatments were fried in canola oil and analyzed for fat uptake and moisture retention.
 One-way analysis of variance (ANOVA) was used and mean comparison was performed by Duncan’s new multiple range test.
 The results showed that by increasing in shear rate, viscosity of coating was decreased. By increasing in propolis concentration, the coating pick up, moisture content, frying yield, were increased while oil uptake were decreased.
 According to the results, 2% concentration propolis gum reduced oil absorption in fried potato strips. Due to their facility to use, propolis gum suggested for coating and usage in industrial potato fries production.
