Abstract

Recently, there has been a considerable interest in non-thermal technologies for preservation of juices due to the growing consumer demands for fresh-like and high quality food products. UV irradiation is one of the non-thermal technologies used for preservation of fruit juices. Since UV treatment is carried out at a temperature lower than conventional thermal processing methods, the adverse effect of heat on juice quality is minimal. Recent advances of UV light technology have indicated that this technology could be used an alternative to heat treatment for fruit juice preservation purposes

Ultraviyole Işın UV Teknolojisinin Meyve Sularına Uygulanması

Abstract

Son yıllarda, tazeye yakın, yüksek kalitede gıda ürünlerine karşı artan tüketici taleplerinden dolayı, meyve sularının muhafazasında ısıl olmayan teknolojilere yönelik büyük bir ilgi oluşmuştur. Meyve sularının muhafazası için uygulanan ısıl olmayan teknolojilerden biri de Ultraviyole UV uygulamasıdır. Bu uygulama, geleneksel ısıl işlem tekniklerine göre daha düşük sıcaklıklarda yürütüldüğünden, sıcaklığın meyve suyu kalitesi üzerine olumsuz etkisi en aza indirilmektedir. UV ışın teknolojisindeki son gelişmeler bu teknolojinin, meyve sularının muhafazasındauygulanan pastörizasyon işlemine bir alternatif olabileceği konusunda oldukça ümit verici olduğunu göstermektedir
