Antioxidants are compounds inhibit or delay oxidative spoilage that beneficial effects on human health increase its importance, recently. Fruits and vegetables, spices and herbs, tea, cereals and grains are rich from the antioxidants contents. The nutritional values show variation during different processes. The variations of certain antioxidants in foods on different storage conditions are examined in this study.

Anahtar Kelimeler

Storage, antioxidant, antioxidant activity, temperature, time

Gıdaların Depolanma Koşullarının İçerdikleri Antioksidanlar Üzerine Etkileri

Öz

Gıdalarda oksidatif bozulmayı önleyen yada geciktiren bileşikler olan antioksidanların son yıllarda insan sağlığı üzerine yararlı etkilerinin ortaya konulmasıyla önemi gittikçe artmaktadır. Meyveler ve sebzeler, baharat ve şifalı otlar, çay, tahıllar ve tohumlar antioksidan içerikleri bakımından zengin olan gıdalardır. Gıdaların bileşiminde bulunan besleyici değerler çeşitli işlemler sonucu değişim göstermektedir. Gıda maddelerinde bulunan bazı antioksidanların farklı depolama koşullarındaki değişimi bu çalışmada irdelenecektir

Anahtar Kelimeler

Depolama, antioksidan, antioksidan aktivitesi, sıcaklık, süre
