Iran is one of the main date palm producers in the world. Date waste was increased, so research around using date products such as syrup, sugar and spread was increased. In this study sucrose replaced with date syrup in Kooshab and physicochemical, rheological and organoleptic properties were studied during 6 months. In this study, various levels of sucrose and date syrup were used for the production of Kooshab, and their effects on physicochemical and sensory properties were studied during 6 months. The SPSS₁₉ software was used for analysis of the data, the statistical test being the Duncan’s test. According to results during 6 months acidity and Brix were constant. Nonalcoholic Kooshab in which the date syrup was used generally have a significant difference (p<0.05) in reducing sugar, color and viscosity with control sample. Samples with 75%, 50% and 25% date syrup have significantly difference with control sample in total sugar, however there was no significant difference between sample with 100% date syrup and control sample. According to sensory results, beverage with 75% date syrup exhibited the highest overall acceptability. Beverages which date syrup used instead of sugar have a desirable characteristic and indicate that substitution of sugar by date syrup didn’t leave any undesirable effects.

Keywords: Key word: Kooshab, date syrup, sugar substitution, organoleptic properties
