In this work we have evaluated the dielectric properties of poly vinylidene fluoride (PVDF) thin films of thickness (≈ 20μm) as a function of temperature from 40-70C and frequency varying from 500 Hz to 100 kHz respectively for Al-Al and Cu-Cu electrode configuration. The dielectric constant values increases with the increase in temperature. A broad peak is found at around (70±5)0C. The maximum...

lycopene is a natural and dominant pigment in tomato which today itsextraction enhancement from tomato and tomato products is trying. in this study atfirst wed use pectinase at 25, 30, 35 and 40 ml/kg concentration at 0, 30, 60, 90,120 and 180 effecting time in 55 0c constant temperature incubation. then beforeextraction half of samples were washed with 94% ethanol at 60 0c for 5 second. ithas ...

Kajmak is a specific dairy product with long term tradition of manufacture in Serbia and few South-East European countries. It manufactured from the thin layer formed on surface hot milk during cooling process. may be consumed as fresh, immediately after manufacture, or maturation period, ripened Kajmak. usually up to 30 days at 15-18 0C stored refrigerator 4 0C. In this work we investigated ef...
