Abstrakt: This research paper focuses on enrichment of yoghurt containing probiotic Lactobacillus casei with persimmon ( Diospyros kaki ) powder in concentrations of 0 (Control) and then 0.5, 1.0, 1.5 and 2.0% (A-D respectively) and determination of some characteristics of the product during refrigerated storage for 21 d. Powder addition affected the color characteristics, textural properties, titratable acidity and water-holding capacity values. The viability of both yoghurt bacteria ( Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus ) and L. casei increased proportionally to adding persimmon powder for all storage days. Furthermore, addition of fruit powder increased short-chain fatty acid and polyunsaturated fatty acid contents. According to sensory analysis results, sample D had the lowest scores from the panelists, whereas the Control together with samples B and C were the most liked yoghurts in terms of flavor characteristics. In terms of overall acceptability, all of the samples received scores over three points on a five-point scale throughout storage. This study indicates that persimmon powder enriched yoghurt is a good vehicle for L. casei and yoghurt bacteria with improved fatty acid profile and acceptable sensory characteristics.
