Abstract
This study aimed to formulate fruit juice yoghurt by incorporating nutritious and flavorful jackfruit juice, known for its health benefits. Jackfruit juice was added at different levels (5%, 10% and 15%) to yoghurt, and various chemical, microbiological, bioactive compounds, and sensory quality characteristics were analyzed. Statistical analysis revealed that panelist acceptability decreased with increasing fruit juice level. Among the samples, yoghurt with 10% jackfruit juice showed significantly different sensory characteristics compared to 5% and 15% jackfruit juice yoghurt, while 5% jackfruit juice yoghurt was similar to plain yoghurt. Chemical analysis indicated increased total solids and acidity with jackfruit juice incorporation, while protein and fat content decreased. Microbiological quality remained acceptable, with microbial counts reduced due to high acidity of jackfruit juice. The research focused on assessing yoghurt using different level of jackfruit juice, conducting analyses encompassing proximate composition, sensory attributes, microbial contents, bioactive compounds and mineral contents of the resulting product. To establish their significance level at P<0.05, the results were compared using one-way analysis of variance (ANOVA). The study’s results indicated significant variations (P<0.05) among the prepared yoghurt, encompassing moisture (ranging from 65.39% – 68.32%), total solid ( 31.37% – 34.06%), carbohydrate ( 19.24% – 22.85%), protein (4.06% – 4.41%), fat ( 6.32% – 7.13% ), ash (0.83% – 0.89% ), acidity ( 0.94% – 1.12%) and ph ( 4.37% – 4.48%) content, as well as sensory characteristics , microbial contents ( TVC, TCC and TFC) and mineral contents ( Potassium , Iron and Phosphorus ) highlighting the diverse nutritional and sensory attributes of different yoghurt samples. The total flavonoid content in jackfruit juice (11.441 mg/QE 100gm) and (1.077 mg/ QE 100gm) in yoghurt (milk+ 10% jackfruit juice). The total polyphenol content in jackfruit juice (0.04467mg GAE/100gm) and (0.0373 mg GAE/100gm). Both samples displayed comparable antioxidant capacities. The sensory analysis revealed notable distinctions among the yoghurt samples in terms of color, taste, texture, appearance and overall acceptance. Overall, the findings suggest that yoghurt can be successfully prepared by adding different proportions of jackfruit juice with milk, with 10% jackfruit juice yoghurt showing slightly better taste due to its higher acid content.
Keywords: Yogurt, jack fruit juice, milk, organoleptic test and microbial test.
