The aim of this work was to determine the effect different drying treatments: freeze-drying, room-drying, and oven-drying on grape phenolic composition 'Regent' 'Cabernet Sauvignon' varieties. After drying, samples were grounded, submerged ultrasound-assisted extraction, analyzed with high-performance liquid chromatography (HPLC). This study demonstrated that use methods significantly affects c...

inject liquid formulation technology (1), the need arose for a process whereby large quantities of highly polished spherical glass microspheres of known density could be manufactured. The process needed to be inexpensive, scalable, GMP-compliant and capable of sterile manufacture for parenteral drugs. Methods such as emulsion drying, freeze drying and spray-freeze drying were all investigated, ...

the canola drying process was investigated using three laboratory scale dryers connected to a computer which continuously recorded the drying processes of each unit. a completely randomized design (crd) with three replications was used for the statistical analysis. the effect of temperature (40°, 50°, 60°c) and air velocity (1, 2 m/s) on the drying kinetics of a monolayer were studied. the effe...

9 10 Plant food materials have a very high demand in the consumer market and therefore, improved food products 11 and efficient processing techniques are concurrently being researched in food engineering. In this context, 12 numerical modelling and simulation techniques have a very high potential to reveal fundamentals of the 13 underlying mechanisms involved. However, numerical modelling of pl...

Grape metabolites can be affected by many extrinsic and intrinsic factors, such as grape variety, ripening stage, growing regions, vineyard management practices, and edaphoclimatic conditions. However, there is still much about the in vivo formation of grape metabolites that need to be investigated. The winemaking process also can create distinct wines. Nowadays, wine fermentations are driven m...

The objective of this work was to estimate the antioxidant potential of the extracts from pink shrimp residue and red grape pomaces (Merlot and Syrah varietals), evaluated according to its antioxidant activity with different analytical methods, associating these properties with the chemical composition of the extract and, as a consequence, with the extraction procedure. The shrimp residue was p...

An unsteady mathematical model of superheated steam fluidized bed drying process is established based on the transport process principles and computational fluid dynamics (CFD) method. The vapor-solid two-phase turbulent flow in the drying chamber is described with the Eulerian-Eulerian multiphase model. The model is solved by computer numerical simulation. The drying experiments of wet rapesee...

The drying kinetics of hawthorn in a pilot-scale experimental fluidized bed dryer with and without vibration was investigated. The effect of operating parameters, such as vibration intensity, drying air flow rate, and temperature, on the drying rate and shrinkage of hawthorn was studied. The hawthorn fruit was dried at various drying air temperatures ranging from 40-70oC and drying air volume f...
