This paper aimed to investigate the amino acid, fatty acid, proximate composition, total phenolic content (TPC), texture, color, and sensory properties of an Emmental type cheese from Ţara Dornelor, Romania as influenced by the processing technology (CA sample made in a stainless steel tank, with spontaneous microflora and ripening of 70 days, and TC sample made in a copper tank, with standard culture and 90 days ripening) and season (winter or summer). The results revealed that the winter samples had higher dry matter content, and were richer in some fatty acids such as palmitoleic acid, isooleic acid, 13-octadecenoic acid, and linoleic acid compared to summer. The season factor influenced significantly (p < 0.05) the amino acid profile, while the processing technology did not have a major impact. The TPC was affected by the processing technology, with the TC sample being the richest. The texture and sensory properties showed significant differences (p < 0.05) depending on the processing conditions and season. TC samples showed lower luminosity, greener, and less yellow nuance compared to CA. A reduction in the color parameters was observed in summer compared to winter. The global acceptance was correlated with the white index, the most appreciated sample obtained in summer, in a stainless steel tank.
