Kullanıma hazır suda çözünebilir keçiboynuzu kabuğu tozu üretiminin yanıt yüzey yöntemi ile çift aşamalı optimizasyonu

Bu çalışmada, mikrodalga destekli ekstraksiyon yöntemi kullanılarak keçiboynuzu kabuğundan elde edilen biyoaktif maddeler (fenolikler) püskürtmeli kurutma tekniği ile çözünür toz forma dönüştürülmüştür. Mikrodalga destekli ekstraksiyon ve püskürtmeli kurutma adımları yanıt yüzey metodolojisi kullanılarak optimize edilmiştir. Ekstraksiyon aşamasında, solvent sıcaklığının ve ekstraksiyon süresinin toplam fenolik madde miktarı üzerine etkisi değerlendirilmiştir. Optimum ekstraksiyon koşulları (toplam fenolik madde miktarı: 84.48 mg GAE/g), 55 °C ve 26 dk olarak belirlenmiştir. Nihai toz üretimi için ise maksimum işlem verimi (%48.00) püskürtmeli kurutucu giriş sıcaklığının 184 °C ve akış hızının 8 mL/dk olduğu noktada sağlanmıştır. Son üründeki fenolik maddelerin varlığı FTIR spektroskopisi ile doğrulanmıştır. Elde edilen tozların toplam fenolik madde miktarı (15.37 mg GAE/g) ve antioksidatif davranışı (DPPH: 0.63 mmol TE/g, ABTS: 0.30 mmol TE/g, FRAP: 0.06 mmol TE/g, CUPRAC: 0.05 mmol TE/g) araştırılmıştır.

Dual optimization for instant soluble carob pod powder production by response surface method

In this study, bioactive compounds (phenolics) from carob pod were extracted by using microwave assisted extraction method. Spray drying technique was performed for the conversion of the resulting extract into powder form. Microwave assisted extraction and spray drying steps were optimized using response surface methodology. In the extraction stage, the effect of solvent temperature and extraction time on the total phenolic content was evaluated. Optimum extraction conditions (total phenolic content: 84.48 mg GAE/g) were determined as 55 °C and 26 min. For the final powder production, the maximum process yield (48.00%) was obtained at the point where the spray dryer inlet temperature was 184 °C and the flow rate was 8 mL/min. The presence of phenolic structures in final product was verified by FTIR spectroscopy. Total phenolic content (15.37 mg GAE/g) and antioxidative behavior (DPPH: 0.63 mmol TE/g, ABTS: 0.30 mmol TE/g, FRAP: 0.06 mmol TE/g, CUPRAC: 0.05 mmol TE)/g) of carob powders were evaluated.
