Abstract

The most prevalent heat treatment method used in the industry to extend shelf life of milk is UHT (Ultra High Temperature) process. However, the gel formation occurred depending on enzymatic and physical effects during storage shortens the shelf life of UHT milk. Heat-stable proteinases produced by psychotropic bacteria, and the native plasmin and plasmin system enzymes in raw milk cause gel formation in UHT milk. These enzymes differently affect casein, which is the most important milk protein, and produce different metabolites in UHT milk. In this review, it is aimed to give information about the mechanism of gelation and enzymes affecting its formation in UHT milk.

Özet

Sütün raf ömrünü uzatmak için endüstride kullanımı en yaygın ısıl işlem yöntemi UHT (Ultra High Temperature - ÇokYüksek Sıcaklık Uygulaması) işlemidir. Ancak, depolama sırasında enzimatik ve fiziksel etkilere bağlı olarak meydanagelen jel oluşumu UHT içme sütlerinin raf ömrünü kısaltmaktadır. Çiğ sütte bulunan psikrotrofik bakteriler tarafındanüretilen yüksek sıcaklığa dirençli proteinazlar ile sütün yapısında doğal olarak bulunan plazmin ve plazmin sistemienzimleri UHT içme sütlerinde jel oluşumuna neden olmaktadır. Söz konusu enzimler, sütün en önemli proteini olankazeine farklı şekilde etki etmekte ve UHT içme sütlerinde farklı metabolitler üretmektedir. Bu derlemede, UHT içmesütlerinde meydana gelen jelleşmenin oluşum mekanizması ve oluşumunu etkileyen enzimler hakkında bilgi verilmesiamaçlanmaktadır.
