Osman Duydu, who has been selling cheese for 30 years in his shop in the historical Tuz Pazarı in Bursa, said that green mould cheese is a strong antibiotic like penicillin. Stating that this cheese also strengthens the immune system, Osman Duydu said, "This cheese is a local cheese produced in Konya Ereğli. It comes in the form of “tulum” and its name is 'Konya green mouldy cheese'. They shred this cheese and mold it in special rooms. It is very useful for diseases in winter and replaces antibiotics and penicillin. In the past, in Ottoman times, before wars, soldiers used to eat this moldy cheese so that they would not get sick and be fit and strong. This cheese is a non-fat, additive-free, highland natural cheese consisting of only milk and yeast. While producing, they first press the overalls. Then they take it out of the overalls and cut it and mold it in special rooms. Then the product turns green and comes to us. This cheese comes to us from Konya Eregli.
