Amorphophallus konjac fresh tubers are often used as a raw material for making food because it has fairly high nutritional content. Therefore, is very important to measure the equilibrium moisture content of andprocessed tuber. The present study aimed determine best model represent adsorption and desorption isotherms tuber slices. samples weresliced into slices (3.0 × 3.0 0.8 cm) rinsed in 0.2%...

varieties of st. john’s wort (hypericum perforatum l.) native to iran possess the largest percentage of hypercin in their leaves and flowers. isotherm curves show the relationship between the relative humidity and moisture content of the plant at a constant temperature. it is essential to understand the isotherms curves for successful storage and drying of the plant. this study used adsorption ...

A fully instrumented air conditioning laboratory unit capable of controlling drying air temperature and humidity integrated with an instantaneous weighing thin layer drying system was used to investigate the thin layer drying behavior and desorption equilibrium moisture content of canola (Brassica napus L.). To this aim, freshly harvested canola samples with moisture content of about 12±0.5% (d...

Abstract Porang tuber ( Amorphophallus muelleri B ) is a from the Araceae family with high glucomannan content (15-64% dry basis). Things that can be done to extend shelf life of porang flour are by doing flouring process. This research aims determine isothermic curve model flour, namely, used estimate equilibrium moisture about rh storage. The method was store samples in desiccator an interval...

Interest in seed propagation of drumstick tree (Moringa oleifera) has created a need for information about the water relationships of its seeds. Thus, we studied the imbibition and desiccation kinetics and adsorption/ desorption isotherms of drumstick tree seeds. Seeds absorbed water readily when imbibed at 23oC. After 17 h of exposure to an atmosphere of 100% relative humidity (RH), seed moist...

Equilibrium moisture content (EMC)/equilibrium relative humidity (ERH) studies pertaining to rice and rice products were reviewed. Methods of determining rice and rice component EMC/ERH data varied, using procedures involving static and dynamic equilibration methods, as well as direct gravimetric methods and indirect ERH‐measurement methods. Methods for measuring rice and rice component moistur...
