Özet
Bu çalışmada, farklı ön-işlem çözeltilerinin [%5 potasyum karbonat (PK), %5 potasyum karbonat (PK) + %1 zeytinyağı (Z) ve %5 potasyum karbonat (PK) + %1 etil oleat (EO)] ve farklı kurutma yöntemlerinin (güneşte kurutma ve endüstriyel kurutma), farklı kiraz çeşitlerinde ('0900 Ziraat', 'Starks Gold') oluşturdukları pomolojik, fitokimyasal ve duyusal değişimlerinin incelenmesi amaçlanmıştır. Bu kapsamda ön işlem uygulamalarına daldırılmış kiraz meyveleri güneşte kurutma yöntemiyle 24 °C'de 48 saat, endüstriyel kurutma yöntemiyle ise 57 °C'de 32 saat kurutulmuştur. Her iki yöntemle de kurutulduktan sonra kiraz örneklerinin; % ağırlık kaybı, pH, titre edilebilir asitlik, suda çözünen kuru madde (Brix,%), renk, toplam fenolik içerik, antioksidan aktivite, toplam antosiyanin içeriği ve toplam flavonoid içeriği ölçülmüştür. Çalışma sonucunda ön işlem solüsyonları uygulanmış ve endüstriyel kurutma yöntemiyle kurutulmuş kiraz örneklerinin kalite parametrelerini korumada, aynı ön işlem uygulanmış güneşte kurutulmuş kiraz örneklerine göre daha etkili olduğu belirlenmiştir. Ayrıca, '0900 Ziraat' ve 'Starks Gold' kiraz çeşitlerinin yağ bazlı ön-işlem çözeltilere daldırılması ve endüstriyel kurutma yöntemi ile kurutularak, kolay bozulabilir olan kiraz çeşitlerinin kalite özelliklerinin optimum seviyede korunduğu bulunmuştur.
This study was aimed to determine the pomological, phytochemical and sensory changes caused by different pre-treatment solutions [5% potassium carbonate (PC), 5% potassium carbonate (PC) + 1% olive oil (OO) and 5% potassium carbonate (PC) + 1% ethyl oleate (EO)] and different drying methods (sun drying and industrial drying) in sweet cherry varietes ('0900 Ziraat', 'Starks Gold'). In this context, cherry fruits dipped in pre-treatment solutions and they were dried at 24 °C for 48 h by sun drying method and by industrial drying method at 57 °C for 32 h. After drying with both methods; % weight loss, pH, titrable acidity, water-soluble dry matter (Brix,%), color, total phenolic content, antioxidant activity, total anthocyanin content and total flavonoid content of cherry samples were measured. As a result of the study, it was found that the cherry samples, which were applied pre-treatment solutions and dried with the industrial drying method, were more effective in preserving the quality characteristics than the sun-dried cherry samples treated with the same pre-treatment solutions. In addition, it was found that the quality characteristics of sweet cherry varieties were preserved at the optimum level by dipping '0900 Ziraat' and 'Starks Gold' cherry varieties in oil-based pre-treatment solutions and drying them with industrial drying method.
