This study evaluated the seasonal impact of feeding systems on the quality traits of cow ricotta cheese produced in semi-extensive farms in Sicily. The research compared ricotta cheese produced during the pasture season (PS) with that from the dry season (DS), analyzing fatty acid (FA) profile, carotenoid and vitamin content, antioxidant capacity, volatile organic compounds (VOC), and color attributes. Results indicated significant improvements in the nutritional quality of PS ricotta cheese, including higher concentrations of CLA (+45%), total PUFA (+17%), and beneficial MUFA, as well as reduced atherogenicity (−10%) and thrombogenicity (−16%) indices in comparison with DS ricotta samples. Additionally, PS ricotta cheese exhibited a more intense yellow color, correlated with increased β-carotene levels compared with DS cheese (5.04 vs. 0.73 mg/g, respectively), as well as distinct VOC profiles reflecting pasture-based feeding. These findings highlighted the potential of PS ricotta cheese as a possible nutrient-rich food and underlined its value for targeted marketing strategies based on enhanced nutritional and sensory attributes. Furthermore, these findings highlight the potential of pasture-fed ricotta cheese to be positioned as a premium, health-focused dairy product. Although this study offers valuable insights, additional research is needed to examine the long-term storage effects on the nutritional stability of PS ricotta cheese, as well as consumer sensory preferences and willingness to pay for pasture-fed dairy.

Abstract

This study evaluated the seasonal impact of feeding systems on the quality traits of cow ricotta cheese produced in semi-extensive farms in Sicily. The research compared ricotta cheese produced during the pasture season (PS) with that from the dry season (DS), analyzing fatty acid (FA) profile, carotenoid and vitamin content, antioxidant capacity, volatile organic compounds (VOC), and color attributes. Results indicated significant improvements in the nutritional quality of PS ricotta cheese, including higher concentrations of CLA (+45%), total PUFA (+17%), and beneficial MUFA, as well as reduced atherogenicity (−10%) and thrombogenicity (−16%) indices in comparison with DS ricotta samples. Additionally, PS ricotta cheese exhibited a more intense yellow color, correlated with increased β-carotene levels compared with DS cheese (5.04 vs. 0.73 mg/g, respectively), as well as distinct VOC profiles reflecting pasture-based feeding. These findings highlighted the potential of PS ricotta cheese as a possible nutrient-rich food and underlined its value for targeted marketing strategies based on enhanced nutritional and sensory attributes. Furthermore, these findings highlight the potential of pasture-fed ricotta cheese to be positioned as a premium, health-focused dairy product. Although this study offers valuable insights, additional research is needed to examine the long-term storage effects on the nutritional stability of PS ricotta cheese, as well as consumer sensory preferences and willingness to pay for pasture-fed dairy.
