FARKLI KURUTMA YÖNTEMLERİNİN BÖĞÜRTLEN KALİTE ÖZELLİKLERİ ÜZERİNE ETKİLERİ VE KURUMA KİNETİĞİ.

In this study, the compatibility of drying kinetics and some quality attributes of dried product were determined by subjecting blackberries to microwave (100 W) and hot air (70°C) drying methods. The experimental results showed that the Logarithmic model was the best fitted model among the investigated drying models regardless of the method of drying (R2=0.9813-0.9827). Water activity, color, hydroxymethylfurfural-(HMF), total monomeric anthocyanin-(TMA) and cyanidin-3-glucoside analyzes were performed on dried blackberry samples. The change in color parameters (L*, a*, b* and ΔE*) of samples dried with hot air is higher than those dried with microwave. HMF (0.50-1.54 mg/kg DM) formation was observed to be lower in microwave dried blackberries. It was determined that the decrease in the TMA content (54.03-576.82 mg/100 g DM) after microwave drying was lower. Similarly, cyanidin-3-glycoside (23.92-320.4 mg/100 g DM) was degraded in higher level in hot air drying. According to the results obtained, it has been determined that microwave drying provides significant advantages in terms of quality characteristics and drying rate. [ABSTRACT FROM AUTHOR]
