AB  - This study aimed to coat mandarin fruits with sunflower oil: sunflower wax oleogel (SOO) and sunflower oil: limonene: sunflower wax (SOLO) oleogel. The peak melting temperatures and storage modulus values of the SOO and SOLO were 61.78 and 59.78 oC, and 110 and 130 kPa. After storage, L colour values (brightness) of the samples were 28.27, 55.80, and 56.05 for the control, SOO and SOLO-coated samples. Total weight loss values of 49.51%, 38.09%, and 26.72% were recorded after the storage. Total aerobic viable counts were 100, 50, and 3750 CFU/g for the control, SOO, and SOLO-coated samples. After storage, the total soluble solids were 5.55%, 6.17%, and 7.65% for the same samples. Fresh fruit had 14.9% total soluble solids. Overall, oleogel coating, especially limonene-containing oleogel, provided significant protection against colour change, weight loss and microbial activity. Further studies with different oleogels and oleogels with lower oleogelator concentrations are suggested.

N2  - Bu çalışmanın amacı, mandalina meyvesini ayçiçek yağı: ayçiçek mumu oleojeli (AAO) ve ayçiçek yağı: limonen: ayçiçek mumu oleojeli (ALAO) ile kaplamaktır. AAO ve ALAO’nun ergime pik noktaları ve depo modül değerleri 61.78 ve 59.78 oC ve 110 ve 130 kPa olarak ölçülmüştür. Bir aylık depolama sonunda mandalina örneklerinin L renk değerleri (parlaklık) kontrol, AAO-kaplanmış ve ALAO-kaplanmış için 28.27, 55.80, ve 56.05 olarak ölçülmüştür. Toplam ağırlık kayıpları da depolama sonunda %49.51, %38.09, ve %26.72 olarak belirlenmiştir. Aynı örnekler için toplam aerobik sayım değerleri ise 100, 50, ve 3750 CFU/g olarak belirlenmiştir. Depolama sonunda toplam çözünür katılar %5.55, %6.17, ve %7.65 olarak ölçülmüştür. Sonuç olarak oleojel kaplama ve özellikle limonen içeren kaplamanın renk değişimi, ağırlık kaybı ve mikrobiyal aktiviteye karşı önemli koruma sağladığı ortaya konulmuştur. Farklı oleojeller ve daha düşük oleojeletör konsantrasyonuyla hazırlanan oleojeller ile daha ileri araştırmalar önerilmiştir.
