Air-coupled ultrasound could be considered a suitable on-line technique for the non-invasive industrial testing of potato products manufactured in slices such as dried, fried or baked chips. Thus, aim present study is to test feasibility air-coupled monitor modifications physicochemical parameters caused by drying. For that purpose, (6 mm) were air dried (60 °C) different drying times (15, 90, ...

In this study, the drying kinetics of saffron stigmas pretreated by atmospheric pressure cold plasma pretreatment (15, 30, 45 and 60 s) followed by hot air drying (60°C and 1.5 m/s) were modeled using 10 conventional mathematical thin layer models. The use of cold plasma pretreatment reduced drying time and enhanced effective moisture diffusivity (Deff). The most accurate models describing beha...

Objective: Button mushrooms (Agaricus Bisporus) are among the most widely produced and consumed mushrooms in the world. Generally speaking, mushrooms are of great nutritional value, which due to their high content of moisture and their corruptibility particular attention is required to be paid to their conservation and health. Drying is one of the most important ways to preserve the yi...

The objective of this study was to determine the drying behavior of 2-phase olive mill waste (2POMW) under isothermal microwave-convection drying conditions. 2POMW samples were dried in a thin layer in a variable-power pilot microwave oven with impinging air, using a feedback controller to maintain sample temperature at one of four levels. Moisture loss and shrinkage of the samples were recorde...

Innovations in food drying processes are usually aimed at reducing time and improving the overall properties of dried products. These important issues from an economic environmental point view can contribute to sustainability whole process. In this study, effects ultrasonic treatment on kinetics pumpkin pulp investigated, mathematical models predict analyzed optimized. The results show that pre...

Characteristics of microwave drying of wood strands with different initial moisture contents and geometries were investigated using a commercial 10 small microwave oven under different power inputs. Temperature and moisture changes along with the drying efficiency were examined at different drying scenar­ ios. Extractives were analyzed using gas chromatography=mass spectrometry (GC=MS). The res...

the effect of pre-treatments in combination with hot air, vacuum and hot-a microwave drying methods the progress of the drying process, and textural, and colour and rehydration rate on button mushroom (agaricus bisporus) slices were investigated. in this work, one of the following methods: hot air, vacuum drying or microwave-assisted convective drying and also different pre-drying treatments, v...
