| Changes in the microbial flora present in six Serrano cheese batches (3 ripened in Summer and 3 in Winter) were studied during production and ripening, to microbiologically characterize this cheese, which is traditionally manufactured by farmers in the south of Brazil, using raw cow milk, without the addition of starter cultures. The levels of several microbial groups were enumerated in the milk, curd and different stages of the 60-day long ripening period. Values of some physicochemical parameters, such as pH, titratable acidity, water activity, moisture and NaCl content were also determined. The correlation coefficients between these parameters and the microbial groups throughout ripening were determined. The influence of the season of the year was also... |

| ABSTRACT: One of the greatest challenges for dairy industries is the correct destination of all the whey generated during cheese making, considering its high impact, the large volume created, and its technological potential. Enzymatic hydrolysis of cheese whey lactose is a biotechnological alternative. However, one of the limiting factors of its use is the relatively high cost of the enzymes, which could be lowered with the immobilization of these biocatalysts. Considering this context, the objective of this research was to evaluate the commercial Kluyveromyces lactis β-galactosidase enzyme immobilized in calcium alginate spheres and gelatin, using glutaraldehyde and concanavalin A (ConA) as modifying agents in the hydrolysis of cheese whey lactose... |
