Evolution of free fatty acid profile during ripening in cheeses manufactured from bovine, ovine and caprine milks with extracts of Cynara cardunculus as coagulant
نویسنده
چکیده
mChanges in the concentrations of free fatty acids (FFA) in bovine, ovine and caprine milk cheeses manufactured with a plant rennet (flowers of Cynara cardunculus) were studied throughout a 68-day ripening period. The long-chain saturated (C16 :0 and C18 :0) and unsaturated (C18 :1, C18:2, and C18 :3) FFA were the most abundant at all stages of ripening. The overall concentration of FFA in fresh cheese was 3598, 3538 and 3868 mg/kg cheese for bovine, ovine and caprine milk cheeses, respectively; these values increased to 5047, 6517 and 5257 mg/kg cheese, respectively, by 68 days, of which 1171, 1734 and 1791 mg/kg cheese, respectively, were accounted for by C4 :0 ±C12 :0. The FFA that showed the highest fractional increase by 68 days of ripening in bovine milk cheese were C4 :0, C6 :0, C8 :0, C12:0, C18 :1 and C18 :2; in ovine milk cheese they were C4 :0, C6 :0, C8 :0, C10 :0, C14 :0, and C18 :1; and in caprine milk cheese they were C4 :0, C8 :0, C10:0, C14:0 and C18:1.

Ras Cheese Making with Vegetable Coagulant - a Comparison with Calf Rennet
Ras cheeses were manufactured using aqueous extract of globe artichoke or artichoke flowers (Cynara scolymus) proteinase as coagulant were compared to calf rennet. There were slight differences between chemical composition of cheese made using vegetable coagulants or calf rennet. Cheeses manufactured with artichoke extract as coagulant exhibited higher (p < 0.05) levels of water soluble nitroge...

Cheese-like systems were manufactured from sterilized ovine milk, using crude aqueous extracts of Cynara cardunculus or cardosin A isolated therefrom as clotting agent. The effect of adding a commercial starter culture was also assessed. The impact of the type of coagulant used during the initial 24 h of proteolysis was evaluated via separation of peptides in the water-soluble extracts by rever...

Terrincho cheese is an uncooked, pressed cheese made from raw whole ovine milk from the "Churra da Terra Quente" breed. It requires a minimum ripening time of 30 d. A detailed evaluation of the effect of ripening time on the breakdown of the casein fractions, along with the formation of major breakdown products of casein hydrolysis, was monitored by HPLC to contribute to a more complete charact...
