Microwave assisted extraction technique was employed to extract pectin from citron peel. Box-Behnken design was applied to investigate the influence of irradiation time, microwave power and pH on the yield and DE of pectin. The finding indicated that the optimal conditions for the maximum yield of pectin (30.71%) were achieved at irradiation time of 3 min, microwave power of 700 W and pH of 1.5...

5(6)-Carboxy-rhodamine 110 isomers were rapidly synthesized by condensation of 3-aminophenol and trimellitic anhydride using microwave irradiation as heating method. After esterification of the two isomers, separation and hydrolyzation provided target products,5-carboxy-rhodamine 110 and 6-carboxy-rhodamine 110, in high yields. The results shows microwave irradiation can effectively reduce ...

  Salmonella     species show different disease syndromes and host specificity, according to their antigenic profile. Salmonella enterica serovar typhimurium is one of the most frequently isolated serovar from foodborne outbreaks. Poultry meat has been identified as one of the principal foodborne sources of Salmonella. In this study, the effect of microwave treatment of chicken meat samples...

Microwave radiometric method is discussed as applied to monitoring of rice growth. The following questions are considered in the paper. Modeling of microwave emission from rice fields. Experimental studies of microwave emission from rice fields. Rice biomass retrieval from microwave radiometric measurements. Examples of monitoring of rice growth with airborne and ground based radiometers.

This paper presents some apprilcations of neural networks in the microwave modeling. The applications are related to modeling of either passive or active structures and devices. Modeling is performed using not only simple multilayer perceptron network (MLP) but also advanced knowledge based neural network (KBNN) structures. Keywords–Neural network, modeling, microwave, microstrip gap, microwave...

The main objective of the study was to compare the effects of halogen lamp–microwave combination baking on quality of breads with other baking methods (conventional, microwave and halogen lamp baking). It was also aimed to improve the quality of microwave baked breads by using combination oven. Weight loss, specific volume, firmness and color of the breads were measured as quality parameters. H...

Microwave heating effects are widely used in the acceleration of organic, polymerization and enzymatic reactions. These effects are primarily caused by the local heating induced by microwave irradiation. However, the detailed molecular mechanisms associated with microwave heating effects on the chemical reactions are not yet well understood. This study investigated the microwave heating effect ...

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),...
