| Popis: | The aim of this study is to investigate the effects of concentrated yogurt (labneh; L) made from cow (Co), camel (Ca), and cashew (Ew) milk (M) and their mixture (100% and 50%) using three strains of probiotic Lactobacillus spp. as starter culture (S) i.e. Lactobacillus plantarum (Lp; S1), L. casei (Lc; S2), L. rhamnosus (Lr; S3) or Lp, Lc, and Lr (S4) in co-cultures with Streptococcus thermophilus and L. delbrueckii subsp. Lactis on the changes of post-acidification and the viability of lactic acid bacteria (LAB) during 0, 7, 14, and 21 days of storage. In addition, sensory evaluation of all yogurt samples was run during the first day of storage. The lowest pH among all samples was seen in Ew-/Ca-ML50%S3 and Ew-/Co-ML50%S3 during the 21 days of storage. S. thermophilus increased to the highest numbers in Co-/Ca-ML50%S3 during 7th and 14th day as compared to other treated samples. All EwML100% were the most accepted by the panels compared to other samples. In conclusion, the combination of EwM with Co-/Ca-M during labneh preparation might enhance the viability of all different starter cultures especially S3 during the storage. |
