Effect of the addition of rosehip marmalade on the textural, rheological, microbiological, physicochemical and organic acid profile of kefir

The effect of the addition of rosehip marmalade on the textural, rheological, microbiological, physicochemical and organic acid profile of kefir during storage was investigated. Samples were also analyzed in terms of some qualitative properties (dry matter, fat, protein, ash, pH, acidity, L & lowast;, a & lowast;, b & lowast;). Both storage time and different formulations were effective on the qualitative properties of the samples. Organic acid content of the samples ranged from nd-5522.7 mg/L and all kefirs showed pseudoplastic flow. Storage time and rosehip marmalade rate had a statistically significant effect on the determined organic acids, color, rheology, yeast, protein, fat, pH and acidity (p < 0.01). While the number of TAMB was statistically significant during storage (p < 0.05), Lactobacillus, Lactococcus, dry matter and ash rate were not statistically significant (p > 0.05). Further, it was observed that the numbers of mold, coliform bacteria and Staphylococcus aureus in the samples were below detectable levels during storage.
