In this paper, water content from celery, corn, and sour cherry were removed through tunnel, fluidized bed, and fluidized bed with microwave dryers. One day before performing the experiments, the fruits were put into a refrigerator and were ground into slices with average dimensions of 5×8×8 mm. For each experiment, 40 g of the samples were inserted in dryers. Moisture content in the samples wa...

ABSTRACT: The combination of pulsed vacuum osmotic dehydration and microwave drying of garlic bulbs were examined. The response surface methodology (RSM) was used to determine the effect of NaCl concentration (8%-20%), osmotic solution temperature (25-65°C), operation pressure (240-830 mbar), immersion time (20-300 min) and microwave power level (100-600 W) on water loss (WL), solids gain (SG),...

background : agaricus blazei mushrooms are one of the most important edible and therapeutic mushrooms, and they contain minerals, vitamins, and amino acids essential for the human body. this mushroom is used raw, dried, and in the form of pharmaceutical products. one of the most important processes after harvesting is drying in order to enhance the quality and the length of maintenance of the p...

Drying of the soymilk residue Okara was investigated by the two different drying processes in order to obtain good quality Okara in respect of its composition and shelf life characteristics. In one method the drying of wet Okara was accomplished in a Vacuum tray drier, maintained at around 758 mm Hg and 50 o C thereby reducing moisture content by as much as 95%. In the other method drying of Ok...

Gloriosa superba is a very important medicinal plant that is used for the treatment of diseases like Gout, arthritis, cancer and act as anthelmintic, antimitotic and antiabortive agent. Its tuber is a great source of Colchicine for the pharmaceutical industries and requires drying before extraction. The accelerated artificial drying technique using Microwave Vacuum oven was evaluated with other...

In this paper the kinetics of osmotic dehydration of carrot and the influence of this pretreatment on the post-drying processes and the quality of obtained products are analysed. Osmotic dehydration was carried out in the aqueous fructose solution in two different ways: with and without ultrasound assistance. In the first part of the research, the kinetics of osmotic dehydration was analysed on...

Foam-mat drying is an alternative method which enables the removal of water from high-sugar content juices and purees that are difficult to dry. The aim of this study was to investigate the effect of different foam-mat drying methods on some physical properties and aroma of apple puree powder. Apple puree was foamed with the addition of foaming agents. Foamed puree was dried as a layer using di...

Fat and moisture analysis by microwave drying and nuclear magnetic resonance (NMR) is a direct method that yields accurate results in minutes without solvents or the frequent calibration required by indirect methods such as near infrared (NIR) or Fourier transform infrared (FTIR). In the past, NMR was unreliable for determining fat content in foods because the signal from moisture present in th...

Finger millet (Eluesine coracana) and foxtail millet (Setaria italica), are highly nutritious minor millets and hence is used in most of the staple foods. The present study was to estimate the thin layer drying characteristics of foxtail and finger millet and developing a thin layer model which adequately fits the data. Foxtail and finger millet with an initial moisture content of 0.314 and 0.3...
