drying is an important operational step in pistachio processing. there is a decrease in moisture content of pistachio nuts from 56-57% (d.b.) to 5-6% during the drying process. drying conditions affect the quality of dried pistachio nuts, therefore, this calls for an accurate description of the drying trend in the process. in this study finite element formulation and solution of diffusive moist...

A new multi-residue method based on solid-phase extraction (SPE) with centrifugation was developed for determination and quantitation of 67 pesticides in water samples. Two SPE cartridges were tested: Chromabond C18 and Oasis HLB. Parameters that influence the extraction efficiency such as the eluent volume, the sample loading volume, the addition of organic solvent to water sample, sorbent dry...

Microwave drying technology has the potential for large production time and energy cost savings versus traditional vacuum drying methods for active pharmaceutical ingredient (API) applications. One of the most critical parameters in the drying process is the determination of the end point, usually at a specified moisture content. On-line mass spectrometry (MS) was used as a tool to monitor micr...

An autoradiographic method has been developed by which the presence of soluble intracellular materials can be determined for individual cells (1). Our immediate need for the method was to measure the uptake of H3-thymidine into soluble pools during various stages of the cell life cycle, but it should be applicable to the assay of various soluble radioactive materials in a variety of cell types ...

BACKGROUND The current typical drying methods for red ginseng are sun drying and hot-air drying. The purpose of this study was to investigate drying characteristics of red ginseng by using far-infrared drying. METHODS The far-infrared drying tests on red ginseng were conducted at two drying stages: (1) high temperature for 24 h drying and (2) low temperature drying until the final moisture co...
