New formulations of fermented milk drinks with fruit pulp added: Physicochemical characteristics during storage and nutritional profile

Abstract

The aim of this study was to evaluate the nutritional profile and the physicochemical characteristics during storage of newly developed formulations of fermented milk drinks with added pineapple, mango and passion fruit pulp. The fermented drinks showed a high content of protein, iron, and calcium. The passion fruit milk drink had the lowest pH (4.13) and highest acidity (0.95%, expressed in % of lactic acid), which was significantly different (p<0.05) from the pineapple and mango drinks. As for syneresis and sedimentation, the pineapple milk drink had the highest rates at 14 days storage, with 34.33% and 6.50%, respectively and was significantly different (p≤0.05) when compared to the mango and passion fruit milk drinks. In conclusion, newly developed fermented milk drinks with added fruit pulp were a source of several nutrients. We observed physical-chemical characteristics suitable for a fermented milk product during storage.
