hot extraction
1.The extraction effects of polysaccharides from the hulls of Physalis alpepengi var. francheti were compared by hot water extraction,supersonic wave extraction and enzyme extraction.
2.The best combination method for extracting Chinese jujube juice was by pectinase treatment following hot water extraction or by ultrasonic wave after pectinase processing.
3.The crude polysaccharide DE was extracted from dried fruitbodies of Dictyophora echinovolvata by hot water extraction, ethanol precipitation and deproteinization with protease method and Sevag method.
4.Well hidden by the winglet/chimney combination, they dramatically improve hot-air extraction from the sidepods, allowing the engineers to lower the rear section of the car, including the exhaust.
5.The results were as follows: leaching solution by hot water extraction was date in color and had mellow date aroma and the highest fusel oil content but strong bitter taste; leaching solution by pectinase enzymolysis had the highest reducing sugar content easy for fermentation but excessively high methanol content in fermenting wine; leaching solution by microwave extraction had the shortest extraction time and fermentation time and the highest ethyl acetate content in wine and the produced wine had special aroma.
6.Three different extraction methods (cold methanol, hot ethanol and alkali extraction) were analyzcd and compared using the direct infusion electrospray ionization-mass spectrometry (ESI-MS) as the evaluation standard.
7.Based upon the fact that the main active principle alkaloids in root of Coptis chinensis are easily soluble in hot water,optimum water extraction conditions were explored by orthogonal tests in comparison with the conventional 50% ethanol extraction process.
9.Unless the pot is very hot, the temperature of the water will drop too low during steeping for the best extraction.
10.During Archaean asthenosphere-lithosphere interaction and post-Archaean interactionwith the deep mantle and other hot spots The Archaean lithospheric mantle beneath SouthAfrica experienced processes of crustal extraction.
