GRANADOS-CONDE, Clemente et al. Obtaining cream cheese supplemented with whey solids and inoculated with Lactobacillus casei. Orinoquia [online]. 2016, vol.20, n.2, pp.40-46. ISSN 0121-3709.

The food industry’s current focus lies mainly on diversifying probiotic products due to their beneficial effects on consumers’ health. This research was thus aimed at producing a cream cheese supplemented with whey solids and inoculated with Lactobacillus casei. Whey and fresh milk’s physical-chemical properties were thus analysed, as well as those of cream cheese; the final product’s microbiological parameters were also evaluated for estimating quality. The results indicated that high-quality cream cheese can be obtained since the results regarding protein and fat were comparable with those of commercial products. It is worth stressing that Lactobacillus casei remained viable for 15 days at the different dilutions evaluated here: 10-4 (1.79E+06 CFU), 10-5 (1.35E+07 CFU) and 10-6 (6.80E+07 CFU). The cream cheese maintained its microbiological quality as the growth of undesirable microorganisms was not observed.
