Abstrakt: Pectin plays a major role in pharmaceutical and food industries. To date, conventional heating method was employed for pectin extraction which was a time-consuming method. Therefore, this study reports the effects of extraction conditions such as microwave power (320-640 Watt), irradiation time (10-20 seconds), and dilution factor (1:10 to 1:30 weight/volume) on the pectin yield from Citrus medica peels were investigated using Box-Behnken Design (BBD)- Response Surface Methodology (RSM). The experimental model shown that the highest pectin yield of 48.8 mg per gram of citron powder was achieved at a microwave power of 480 W, irradiation time of 20 s, and dilution factor of 1:10 weight/volume (w/v), which was close to the RSM predicted value (47.09%). The extracted pectin was characterized in terms of the degree of esterification (51.49%), emulsion activity (40.9%), and emulsion stability. The presence of poly galacturonic acid was confirmed by FTIR, EDX, and TGA studies. [ABSTRACT FROM AUTHOR]
