Agribusiness, EarlyView.ABSTRACT This study examines food price inflation rate convergence among EU27 Member States from 2005 to 2024, focusing on structural breaks, external shocks, and regional disparities. Using panel unit root tests and club convergence analysis, the findings reveal no overall convergence but identify multiple convergence clubs.

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT This study investigated the use of oleogel systems as fat replacements in chocolate cream fillings. Oleogels were prepared with 4, 6, 8, or 10% of sunflower wax (SW) or glycerol monostearate (GM) in corn oil (CO) or sesame oil (SO). Four representative oleogels, SOSW4, SOSW6, SOGM6, and COGM6, were selected for application in chocolate cream ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.
