Microwave assisted extraction (MAE) tech-nique was employed for the extraction of pectin from black mulberry (Morus nigra) pomace in this research. The effects of process variables namely microwave power (300-900 watt), irradiation time (10-30 min) and liquid to solid ratio (15-30 mL/g) on the yield, degree of esterification (DE) and galacturonic acid content (GalA) of pectin were investigated ...

A two fluid model (TFM) was used to study gas-solid heat transfer in a riser with different inclination angles. A two dimensional pipe with 5.8 cm internal diameter and 5 meter length was chosen.  Effect of bed angle and solid particles feed rate were studied on the heat transfer behavior of gas and solid particles. Obtained results from simulation are compared with the experimental data in the...

The effects of different solvents, temperature conditions, solvent-solid ratios and particle sizes on solid-solvent extraction of the total phenolics, proanthocyanidins and flavonoids herein also referred to as antioxidant from pomegranate marc peel (PMP) was studied. Water, methanol, ethanol, acetone, and ethyl acetate extraction efficiencies at extraction times of 0.17 to 10 min, extraction t...
