Abstract
Bu çalışmada çörek otu posasının iki farklı reçete ile marmelada işlenmesi sonucunda toplam fenolik madde, toplam antioksidan kapasite ve bireysel fenolik bileşenlerin biyoerişilebilirliğinde meydana gelen değişimler in vitro sindirim modeli ile incelenmiştir. UPLC-ESI-MS/MS analizi, klorojenik asit, p-salisilik asit ve o-salisilik asidin hem çörek otu posasında hem de marmelatlarda ana fenolik bileşikler olduğunu ortaya koymuştur. Çörek otu posasının marmelada işlenmesi toplam fenolik madde içeriğinde, toplam antioksidan kapasitede ve tüm bireysel fenolik bileşiklerin konsantrasyonlarında istatistiksel olarak önemli düşüşlere neden olmuştur (P<0.05). Haşlama ön işleminin uygulandığı reçete ile hazırlanan marmelatlar duyusal değerlendirmede üstün bulunmakla birlikte, ön işlemsiz olarak hazırlanan marmelatlarda biyoerişilebilir fenolik bileşen seviyelerinin daha yüksek olduğu tespit edilmiştir. Sonuç olarak, bu çalışmada elde edilen bulgular; çörek otu posasının marmelat yapımında değerlendirilmesi ile sürdürülebilir atık yönetimine katkı sunulabileceğine dikkat çekmiştir.

Abstract
In this study, the changes in the bioaccessibility of total phenolics, total antioxidant capacity, and individual phenolic compounds resulting from the use of black cumin pomace in marmalades prepared with two different recipes were examined using an in vitro digestion model. UPLC-ESI-MS/MS analysis revealed that chlorogenic acid, p-salicylic acid and o-salicylic acid were the main phenolic compounds present in both the black cumin pomace and the marmalades. Processing black cumin pomace into marmalade caused statistically significant reductions in total phenolic content, total antioxidant capacity, and levels of all individual phenolic compounds (P<0.05). While the marmalades prepared with the recipe that included a blanching pre-treatment were found to be superior in sensory evaluation, the marmalades prepared without pre-treatment had higher levels of bioaccessible phenolic compounds. Overall, the findings of this study highlight that utilizing black cumin pomace in marmalade production can contribute to sustainable waste management.
