Abstract
Pulsed electric field (PEF) and osmotic dehydration (OD) pretreatment can accelerate the time‐consuming drying process and minimize its high energy demands. The effect of PEF and OD pre‐processing conditions and osmotic solution composition on mass transfer kinetics (water loss, solid gain, water activity) and quality properties (color, texture, total sensory quality) during OD and subsequent...
This article presents the results of a research project that investigated the extent to which the use of the historical episode of the Millikan-Ehrenhaft dispute over the existence of the elementary electric charge can improve students’ conceptions of specific aspects of the Nature of Science (NOS). A teaching programme containing seven hourly teaching units was designed and implemented. The teaching...
