The ultrasound‐assisted vacuum (USV) drying technique is a novel method and ultrasonic treatment under vacuum causes to accelerate the dehydration rate of food materials. This study compared the drying kinetics and some quality parameters for green beans subjected to USV, oven, and vacuum drying at 55, 65, and 75°C. The drying time was shortened by around 1 hr using USV at each temperature. Effective moisture diffusivity values was found between 2.00 × 10−10 − 4.81 × 10−10 m2 s−1 and it was increased compared with control treatment between 8.9% and 24.5%. USV treatment resulted phenolic compounds compared with unsonicated control. However, USV caused more color change than the control, oven and vacuum. Lower the total color difference values were obtained for samples dehydrated by vacuum dryer. USV had greater advantages compared with the control and it can potentially be applied to green beans and other vegetables for faster drying processing.Practical applications
This study exhibit the usability of ultrasound‐assisted vacuum dehydration to increase the drying rate, to improve the energy efficiency of the drying process and to develop quality of the final products. The results indicated that ultrasound treatment could be used as an assistant technique to accelerate drying rate and improve product quality. Besides mathematical models and drying kinetic, this study presents useful information about the different dehydration process for green bean. It was expected that this study will great contribution to literature, food science and technology.
Abstract The single radial immunodiffusion assay has been the accepted method for determining the potency of inactivated influenza vaccines since 1978. The world‐wide adoption of this assay for vaccine standardisation was facilitated through collaborative studies that demonstrated a high ... more
Abstract Background Whether morbidity from the 1918‐19 influenza pandemic discriminated by socioeconomic status has remained a subject of debate for 100 years. In lack of data to study this issue recent literature have hypothesized that morbidity was “socially neutral”. Objectives ... more

Higher coffee consumption is linked with a lower risk of endometrial cancer, a type of cancer that begins in the lining of uterus, according to an analysis of relevant studies published to date. Also, caffeinated coffee may provide better protection than decaffeinated coffee. The analysis, ... more
Smart skin that can respond to external stimuli could have important applications in medicine and robotics. Using only items found in a typical household, researchers have created multi-sensor artificial skin that's capable of sensing pressure, temperature, humidity, proximity, pH, and air ... more
