135 6. ÖZET FARKLI KOŞULLARDA OLGUNLAŞTIRILAN BEYAZ PEYNİRLERİN OLGUNLAŞMA İNDEKSLERİNİN SAPTANMASI Bu çalışma, farklı pastörizasyon ısılarında ve farklı starter kültürler kullanmak suretiyle (72 C'de 2 dk. pastörize edilen sütlere S.cremoris % 95, S.lactis % 5, CHR, HANSEN No:54“I.tip peynirler”; 85 C'de 1 dk. pastörize edilen sütlere CHR.HANSEN'S YC 30, VISBYVAC Yoghurt 4“Il.tip peynirler”) imal edilen beyaz peynirlerde % 6, % 12 gibi değişik salamura oranlarının ve vakum pa ketlemenin olgunlaşma üzerine etkilerini incelemek amacıyla yapıldı. Çalışmada materyal olarak inek sütünden hazırlanmış 108 adet beyaz peynir numunesi kullanıldı. Bu numuneler kurumaddede, yağ, tuz, asitlik, toplam azot, suda çözünebilen azot ve olgunlaşma indeksi bakımından incelendi. Kim yasal yönden bu analizler, 90 günlük olgunlaşma periyodu içinde 7, 15, 30, 45, 60 ve 90. günlerde yapıldı. Numunelerde kurumaddede tuz miktarı yönünden yapılan incelemede I tip peynirlerde % 6'lık grupta % 7.73-8.39 (ortalama % 7.89), % 12'lik grupta %1 1.27-12.75 (ortalama % 12.09), vakum ambalajlı, grupta % 6.96-7.52 (ortalama % 7.21); Il.tip peynirlerde % 6'lık grupta % 7.56-8.06 (ortalama % 7.84), % 12'lik grupta %1 1.47-1 1.95 (ortalama % 11.77), vakum ambalajlı grupta % 5.65-6.32 (ortalama %6.05) arasında bulundu. Numunelerde titre edilebilir asitlik I.tip peynirlerde % 6'lık grupta %1.64-1.93 L.A.

Her iki tip peynirin vakum ambalajlı grubundaki numuneleri %6 ve % 12'lik salamurada olgunlaştırılan peynirlere nazaran daha kısa sürede olgunlaştığı ve aynı zamanda olgunlaşma süresi boyunca kurumadde miktarlarında değişiklik olmadığı saptanmıştır. Anahtar kelime : Beyaz peynir, Olgunlaşma indeksi.
