Introduction: Fruit polysaccharides, essential health factors in foods, are widely present in edible fruits. Several methods for isolation of polysaccharide are available. Microwave Assisted Extraction (MAE) method is extensively used for separation of polysaccharides. Only little information is available about Psidium guajava L. Fruit Polysaccharide (PFP) and its extraction methods. Objective:...

Continuous counter-current extraction of rhenium from roasting dust leach liquor was carried out using a mixer-settler extractor. Tributylphosphate was used as the extractant diluted in kerosene. The effects of the flow rates and extraction stages number were investigated. The extraction efficiency was affected by the flow rates of the aqueous and organic phases, and its mechanism was qualitati...

Aqueous extraction of basil seed mucilage was optimized using response surface methodology. A Central Composite Rotatable Design (CCRD) for modeling of three independent variables: temperature (40-91 °C); extraction time (1.6-3.3 h) and water/seed ratio (18:1-77:1) was used to study the response for yield. Experimental values for extraction yield ranged from 7.86 to 20.5 g/100 g. Extraction yie...

Background and Objectives: Berberis vulgaris, an Iranian native plant, includes valuable compounds such as berberine with therapeutic, health-promoting and nutritional effects. However, major parts of this plant are discarded as wastes. The major aims of this study were optimization of berberine extraction conditions from the whole plant with maximum antioxidant activity, the extract microencap...

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 ...
