چکیده انگلیسی
The current work deals with understanding the fundamental aspects of intensified recovery of lactose from paneer (cottage cheese) whey using the anti-solvent induced sonocrystallization. Ultrasonic horn (22Â kHz) with varying power levels over the range of 40-120Â W has been used for initial experiments at 100% duty cycle and two different levels of ultrasonic exposure time as 10Â min and 20Â min. Similar experiments were also performed using ultrasonic bath for the same time of exposure but with at two ultrasonic frequencies (22Â kHz and 33Â kHz). It was observed that the lactose recovery as well as purity increased with an increase in ultrasonic power at 100% duty cycle for the case of treatment time as 10Â min whereas the lactose recovery and purity increased only till an optimum power for the 20Â min treatment. In the case of ultrasonic bath, lactose purity increased with an increase in the ultrasonic frequency from 22Â kHz to 33Â kHz though the lactose recovery marginally decreased. Overall, it was observed that the maximum lactose recovery was â¼98% obtained using ultrasonic horn while the maximum lactose purity was â¼97%. It was also observed that maximum lactose recovery was â¼94% for the case of ultrasonic bath while the maximum lactose purity was â¼92%. The work has enabled to understand the optimized application of ultrasound so as to maximize both the lactose yield and purity during the recovery from whey.
