摘要

This study aimed to evaluate the physicochemical, rheological, and sensory properties of ricotta-like synbiotic cheese (RiC) formulated from cow’s whey with different concentrations of inulin and CaCl2 during storage. The pH, acidity, protein, and solid content of synbiotic RiC were in the range of 4.21–5.2, 0.42–0.75%, 11.21–12.37%, and 19.17–22.1%, respectively. The results showed that increasing the amounts of inulin and CaCl2 had significant effect on the pH, acidity, protein, and solid content of synbiotic RiC (P < 0.05). Also, the presence of inulin and CaCl2 had a significant effect on the L*, b*, and a* values of synbiotic RiC samples (P < 0.05). The frequency sweep test revealed that the η*, G′, and G′′ values increased at higher CaCl2 concentrations in treatments. The inulin and CaCl2 had also a significant effect (P < 0.05) on improving the viability and survival of Lactobacillus acidophilus. In general, synbiotic RiC sample containing 3% inulin and 150 ppm CaCl2 had the highest overall acceptability score in terms of sensory evaluation.
