Kinnow mandarin (Citrus reticulata) peel, an agricultural solid waste of the juice processing industry, was studied to understand mass transfer kinetics during osmotic dehydration and its process optimization. The experiments were conducted in sucrose (40, 50, 60° Brix) at different temperatures 40, 60°C duration 0–240 min. Central Composite Design used for optimization with variables, such as ...

Abstract. We develop a general theory of the swelling kinetics of polymer gels, with the view that a polymer gel is a two-phase fluid. The model we propose is a free boundary problem and can be used to understand both contraction and swelling, including complete dissolving or dehydration of polymeric gels. We show that the equations of motion satisfy a minimum energy dissipation rate principle ...

The production of dried snacks with high nutritional value represents a valid alternative to use the kiwifruit waste as undersized fruits, positive economic impact on entire chain. Therefore, this work aimed evaluate effect pulsed electric field - PEF (200 V/cm) and/or osmotic dehydration – OD pre-treatments drying kinetics (50, 60, 70 °C), texture, colour, and sensorial properties yellow snack...

Magnesium chloride hydrates are characterized as promising energy storage materials in the built-environment. During the dehydration of these materials, there are chances for the release of harmful HCl gas, which can potentially damage the material as well as the equipment. Hydrolysis reactions in magnesium chloride hydrates are subject of study for industrial applications. However, the informa...

Although proteins consist exclusively of L-amino acids, we have reported that aspartyl (Asp) 58 and Asp 151 residues of αA-crystallin of eye lenses from elderly cataract donors are highly inverted and isomerized to D-β, D-α and L-β-Asp residues through succinimide intermediates. Of these Asp isomers, large amounts of D-β- and L-β-isomers are present but the amount of D-α-isomer is not significa...

BACKGROUND Racecadotril is an antidiarrhoeal drug with intestinal antisecretory mechanism of action. AIM To assess racecadotril efficacy as an adjunct to oral rehydration solution, against oral rehydration solution alone or with placebo in childhood acute gastroenteritis. METHODS Individual patient data meta-analysis following multilevel mixed models testing the significance of the treatmen...
