Qualidade de Doce de Leite e Iogurte Oriundos de Leite de Vacas Girolando Submetidas a Sombreamento

Abstract

The objective was to evaluate the effect of shading on the production and quality of dulce de leche and milk yogurt from Girolando cows, through the evaluation of the milk physicochemical composition, somatic cell count (SCC) and total bacterial count (CBT). A total of eight Girolando cows were subjected to two treatments, paddock with shading and paddock without shading. At the end of the experiment, milk was weighed and collected from each treatment for the manufacture of dulce de leche and yogurt. To compare the average chemical composition of milk from dulce de leche and yogurt it was carried out the ANOVA using Tukey's test at 5% significance. For the sensory analysis, the samples were coded with three random digits informed by the tasters on the forms. The results were compared by the Q Cochran test (p < 0.05). There was no difference in the physical-chemical and sensory composition between the treatments in the manufacture of dulce de leche. However, for yoghurt in the sensory analysis, there was a difference between the treatments (p<0.05), and the most palatable by the judges were the yoghurts of the shade treatment. There was no effect of shading on the production and quality of dulce de leche and milk yogurt from Girolando cows.
