Profile Assessment of Bioactive Peptides in the Greek Traditional Cheese “Tsalafouti”

In the Greek regions of Agrafa and Tzoumerka, Tsalafouti, a traditional spreadable cheese made from goat’s and sheep’s milk is produced. This product has emerged in recent years as a result of the campaign to acquire Geographical Indication. This study aimed to assess the biopeptide profile of Tsalafouti cheese in order to highlight its nutritional value. Using HPLC-MS, bioactive peptides in Tsalafouti cheese samples were identified and classified according to their bioactivity. The biopeptides detected are known to present antibacterial, anti-diabetic, anti-hypertensive, anti-thrombotic, antioxidant, and immunomodulatory activities, while ACE enzyme and dipeptidyl-4 (DPP-IV) inhibitors were also identified. Based on these results, Tsalafouti cheese presents an interesting bioactive peptides profile that may act as special motivation for consumers to choose this specific cheese.
