common drying systems, including hot air convection, infrared, vacuum and ir-convective were employed to investigate and analyze the drying process of mulberry fruits. to evaluate the effect of pretreatment on the drying phenomenon, samples were pretreated by being subjected to: microwaves, chemical preparation, mechanical as well as blanching approaches. results revealed that the microwave pre...

sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. so it is can be used as a sugar source in many processes. lignin and hemicellulose must be removed before hydrolysis of cellulose. several different pretreatment approaches have been studied. the purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

introduction: the use of lopinavir/ritonavir (lpv/r) has decreased morbidity and mortality due to human immunodeficiency virus (hiv); however its use could be impaired by hepatotoxicity. therefore, this study was designed to investigate the effects of melatonin (mt) and alpha lipoic acid (ala) on lpv/r-induced hepatotoxicity in male albino rats. methods: rats were divided into groups and treate...

anaerobic digestion is a feasible technology to stabilize the solid waste generated inslaughterhouses obtaining significant quantities of biogas, considered as a clean and renewable fuel. this iswhy it is important to optimize the digestion process in order to eliminate organic matter and maximize theproduction of biogas. in this work, a system was developed for treating slaughterhouse solid wa...

drying is one of the most important steps in raisin processing. during this step, initial moisture content decreases up to 15-17% (db) for suitable storage. achieving optimum drying conditions can affect the processing time and improve raisin quality. temperature, air velocity and pretreatment are important factors in the quality of the grape drying process. in this research, the effect of temp...

slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. maximum glucose yield ...

electrochemically generated iron can remove most contaminants present in water and wast water, by precipitation, adsorption, electrostatic interaction, and complex formation (generally called electrocoagulation-ec). in the present paper, pretreatment of brackish water having high total hardness (th), alkalinity (a),  and cl¯ ions, is studied by application of a dc-electrical current ot the iron...

in large regions of the world, biomass is a very important source of energy. the global bioenergy market based on forest biomass is growing rapidly. about 92 % of the bioenergy in sweden comes from forests. biomass from forests is not homogenous. the locations, transport distances, and transport methods, can differ very much and the industries that need biomass as input prefer raw materials wit...

the objective of this study was to investigate dehydration kinetics of barberry (berberis vulgaris l.) at different drying temperatures (60 ºc, 70 ºc, 80 ºc), air velocities (0.3 m s-1, 0.5 m s-1, 1 m s-1) with two types of pretreatment. drying time and colour quality during dehydration were experimentally determined. barberries were dried from the initial moisture content of 73.44% (w.b.) to t...
