Influence of osmotic dehydration pre-treatment on oven drying and freeze drying performance [PDF]
Drying is largely used in food industry, since it allows prolonging the product shelf life by inhibiting microorganisms' growth and enzyme activity. Traditional drying techniques, such as air drying and freeze drying, suffer from several drawbacks, mainly long processing time, low rehydration capacity and change in food properties. Some pre-treatments,

Convective drying kinetics of osmotically pretreated papaya cubes [PDF]
ABSTRACT This study assessed the fitting of mathematical models to the convective drying kinetics of osmotically pre-dehydrated papaya cubes. Papaya cubes were subjected to osmotic dehydration in sucrose solutions at 40 and 50 ºBrix, at temperatures of 50 and 60 ºC, followed by complementary convective drying in forced air circulation oven under three ...

New Polymer Tensiometers: Measuring Matric Pressures Down to the Wilting Point [PDF]
Tensiometers are commonly used for measuring soil water matric pressures. Unfortunately, the water-filled reservoir of conventional tensiometers limits their applicability to soil water matric pressures above approximately –0.085 MPa. Tensiometers filled

Dry powder coated osmotic drug delivery system
Dry powder coated osmotic drug delivery system (ODDS) were prepared and characterized using an innovative powder coating technology. Coating powder adhesion to the surface of the ODDS core was firstly performed through an electrostatic spray gun, followed by a curing step to allow those electrically deposited particles coalesce and form a continuous ...

Drying and Osmotic Conditioning in Hancornia speciosa Gomes Seeds [PDF]
Hancornia speciosa is a native tree species of the Brazilian Cerrado whose seeds are desiccation sensitive. In this study, we aimed to evaluate drying and osmotic conditioning in H. speciosa seeds. We used fresh seeds with 48% moisture content, which were slowly dried until they attained contents of 20%, 15%, 10% and 5%.
