Yüksek gerilim darbeli elektrik alanı tekniğinin gıdaların korunmasında kullanımı

Yüksek gerilim daıbeli elektrik âlaîlı (DEA) tekniği iki elektrot araşma yerleştirilmiş gıdaya yüksek voltajlı (20-80 kV/cm) elektrik darbelerinin uygulanmasıdır. DAE teknokiisi geleneksel ısıl işlem yöntemine göre siper bir metot olarak belirtilmektedir. Çünkü OHA gıdaların fiziksel ve duyusal Özelliklerinde istenmeyen değişikliklere neden olmamakta veya büyük ölçüde azaltmaktadır. DEA ekmek, süt, portakal ve elma suyu, sıvı yumurta, gibi gıdaların kalitesini korumak amacıyla kullanılmaktadır. Gıda kaynaklı mikroorganizmalar üzerinde DEA'nın öldürücü etkisi tespit edilmiştir. DEA uygulaması gıdaların saklama süresini artırmıştır.

Uses of high intensity pulsed electric field in the preservation of foods

High intensity puked electric Held (PfiF)' processing is the application of high voltage (20-80 kV/cm) electrical pulse food placet! fetweeri 2 decpodes* PEF technology is considered superior to traditional heat treatment of foods becite it avoids of greatly reduces the detrimental changes of the seösosy and physical properties of foods. PEF are applied to preserve the cjuality of foods, such as bread, milk, orange and appie juice, liquid eggs, etc. The lethal effect Of PEF was observed on fbodborne microorganisms. PEF applications were increased the shelf life of foods.
