Dielectric Properties of Frozen Surimi at 915 MHz and 2450 MHz

Dielectric Properties of Sweet Potato Purees at 915 Mhz as Affected by Temperature and Chemical Composition

A process for rapid sterilization and aseptic packaging of sweet potato puree using a continuous flow microwave system operating at 915 MHz has been successfully developed. In microwave processing, dielectric properties have a major role in determining the interaction between purees and the electromagnetic energy. The objective of this research was to determine how dielectric properties are aff...

A comparison between 915 MHz and 2450 MHz microwave ablation systems for the treatment of small diameter lung metastases.

PURPOSE We aimed to retrospectively compare the local tumor control rates between low frequency (LF) and high frequency (HF) microwave ablation devices in the treatment of <3 cm lung metastases. METHODS A total of 36 patients (55 tumors) were treated with the LF system (915 MHz) and 30 patients (39 tumors) were treated with the HF system (2450 MHz) between January 2011 and March 2016. Compute...

Pasteurization of pickled asparagus using 915 MHz microwaves

Asparagus spears are sensitive to thermal treatments. Lengthy pasteurization at elevated temperatures may cause severe thermal degradation. In this research we explored the application of short-time microwave pasteurization for pickled asparagus in glass bottles and studied the effect of this process on the textural quality of the products in comparison with the conventional hot-water pasteuriz...

Effect of Dielectric Properties of a Solvent-Water Mixture Used in Microwave-Assisted Extraction of Antioxidants from Potato Peels

The dielectric properties of a methanol-water mixture were measured at different temperatures from 20 to 80 °C at two frequencies 915 MHz and 2450 MHz. These frequencies are most commonly used on industrial and domestic scales respectively. In this study, the dielectric properties of a methanol-water mixture were found to be dependent on temperature, solvent concentration, and presence of plant...
