Recently, with a broadening range of available materials and alteration of feeding processes, several extrusion-based 3D printing processes for metal materials have been developed. An emerging process is applicable for the fabrication of metal parts into electronics and composites. In this paper, some critical parameters of extrusion-based 3D printing processes were optimized by a series of exp...

Three main parameters influence the nutritional quality of food preparation: the choice of raw materials, the recipe and composition of a meal, and the preparation process. In catering systems the temperature and time history during preparation and distribution, i.e. systems like cook-chill, cook-freeze, or warm-holding, need particular attention with regard to some sensitive nutrients, e.g. vi...

Although a dynamic headspace/gas chromatography-mass spectrometry (DH/GC-MS) method is an effective tool for determining volatiles of irradiated turkey meat, the profile of volatiles may be changeable depending upon the availability of oxygen in the sample vial and sample holding time before purge. The objective of this study was to evaluate the effects of helium flushing and sample holding tim...
