چکیده انگلیسی
The present study was undertaken to produce functional Scamorza cheese from Gentile di Puglia ewe milk by incorporating probiotic strains into the cheese matrix and to evaluate the physicochemical characteristics of Scamorza ewe milk cheese. Gentile di Puglia ewe bulk milk was used for Scamorza cheese production. Cheeses were denoted S-CO for control Scamorza cheese, S-BB for Scamorza cheese made using a mix of Bifidobacterium longum and Bifidobacterium lactis, and S-LA for Scamorza cheese made using Lactobacillus acidophilus as probiotic strain. Cheeses were analyzed at 1, 7, and 15 d of ripening. Probiotic cell recovery in cheese was 7.55 ± 0.07 log10 cfu/g and 9.09 ± 0.04 log10 cfu/g in S-LA and S-BB cheese, respectively; probiotic cheeses also displayed the highest levels of lactic microflora. Reverse-phase HPLC chromatograms of the water-soluble nitrogen fraction showed a more complex profile in S-BB, with distinctive peaks in the early-eluting zone. The matured Scamorza cheese containing the mix of B. longum and B. lactis was characterized by significantly higher levels of Gln, Ser, Arg, Ile, and Leu, whereas cheese containing Lb. acidophilus was characterized by higher levels of Tyr and Met. Total FFA content was the highest in S-LA, intermediate in S-BB, and the lowest in S-CO cheese; in particular, Scamorza cheese containing Lb. acidophilus showed the highest level of vaccenic acid, oleic acid, and total conjugated linoleic acid. Probiotic bacteria survived through the technological phases of pasta filata cheese production, maintained their specific metabolic pathways, and conferred functional properties to Scamorza ewe milk cheese.
