Zaman-Sıcaklık Belirteçlerinin Gıda Sanayisindeki Önemi

Gıdaların taşınması ve depolanması sırasında maruz kaldıkları sıcaklıkların ve süresinin belirlenmesi, gıdaların raf ömürleri üzerine etkisinin incelenmesi, ve gıdaların kalan raf ömürlerinin doğru olarak tespit edilebilmesi için zaman-sıcaklık belirteci TTI uygulaması önemli bir uygulamadır. Süt gibi uygulanan ısıl işlemin gıdanın besin ve duysal özellikleri üzerine etkisinin önemli olduğu durumlarda uygulanan ısıl işlemleri optimize etmek için TTI kullanılması ile ilgili çalışmalar literatürde yer almaktadır. Özellikle dondurulmuş gıdalarda TTI kullanımının önemi uzun yıllardır bir çok çalışmaya konu olmakla birlikte henüz ülkemizde bu konuya gereken önem verilmemektedir.

Zaman-Sıcaklık Belirteçlerinin Gıda Sanayisindeki Önemi

The use of time temperature indicators TTI is an important application to monitor the changes in the temperature and the duration period during storage and transportation of food products, to determine the effect of these changes on the shelf-life, and to evaluate the correct shelf-life. There have been some studies in the literature on the usage of TTI to determine the optimum heat treatment for some food products like milk, for which exceeding temperature of the heat treatment could cause some problems on the nutritional and sensorial properties. Although the use of TTI especially for frozen products has been a subject for most of the studies, the necessary attention has not been given in our country up to now.
