BACKGROUND: Today, some countries have focused on dairy-based drinks at the schedule of dairy's production, to solve the problem of high consumption drinks and low intake of dairy. The purpose of this study is producing of flavored drinking yoghurt containing date syrup, In order to remove sugar; and also using Lactobacillus plantarum to improve the health of product.
 Methods: In this study, we prepared 5 and 10% of date syrup as a natural sweetener, 0.5 and 1% pectin as a stabilizer; then 109 cfu / ml of Lactobacillus plantarum (as probiotics) was added. After making healthy and cooling, the samples were packaged in suitable sterile containers. Then some physicochemical properties and general acceptance of this production were investigated during 31 days at low temperature.
Findings: The results showed that by increasing the amount of stabilizer (pectin), the sedimentation rate was decreased (from 17.47±0.02% to 10.51±0.12%) and the apparent viscosity was increased (from 103.67 ±0.07 cP to 181.00±0.05 cP), significantly (p<0.05). The highest overall acceptance (3.61±0.51), compared to other samples, was related to the sample of 10% date syrup and 1% pectin.
Conclusion: Drinking yoghurt containing 10% pectin date syrup and 1% has higher score of physicochemical properties and overall acceptability than other received samples; so this product can be introduced as a probiotic dairy and nutritious drink.
