7. Quality appraisal of Mango flavored milk prepared from different combinations of Nili Ravi buffalo and Holstein Friesian cow milk
Abstract
Present study was carried out to assess the compositional quality of mango flavored milk produced from Nili Ravi buffalo (100%), Holstein Friesian cow milk (100%); the best milk breeds globally recognized and their blends in 75%:25%, 50%:50% and 25%:75% respectively. Another aim was to evaluate which of buffalo and cow milk or their blends will best meet consumers demand in terms of their compositional quality and taste. Shelf life was also considered for all the flavored milks. Trained judges were asked to evaluate each of the five groups of flavored milk samples and provided feedback about their sensory assessment. Comparative analysis was undertaken using one-way ANOVA at SPSS 17 for significant difference comparison, while cross tabs and chi-square tests were used for the distribution and significance of response of the consumers for the taste of milk. Results indicated that five groups of flavored milks differed significantly among each other (p<0.05). The difference among the groups was also statistically significant for all the parameters except lactose (p = 0.341). Shelf life of all the samples showed reasonably good results till 7 days of storage at refrigerated temperature of 4ºC. As per majority of the respondents, flavored milk prepared from buffalo milk (T0) remained the best among all five groups of flavored milks with respect to all tested quality parameters as Pakistani consumers always prefer buffalo milk over cow milk for its overall acceptability of taste, odor and colour.
