  Background: Fiore Sardo PDO is one of the oldest Mediterranean hard cheeses, exclusively produced in Sardinia (Italy) from raw whole ewe’s milk. Some manufacturers, improperly, submit raw milk to heat-treatment. Aim of this study was to evaluate the proteomic profile of Fiore Sardo PDO and to investigate possible differences between cheese made from raw milk and from heat-treated milk. Materials and methods: Starting from the same ovine bulk milk, eight cheese wheels of Fiore Sardo PDO were produced, four from raw milk and four from heat-treated milk. The subsequent production steps were the same for both types of cheese as was sampling at different ripening times. Samples were analyzed by Urea-PAGE electrophoresis. Afterwards, blind analysis of 32 cheese samples, produced by 17 different cheesemakers was performed to evaluate the meth.. View More»
