Opis

The juice from fruits and vegetables is commonly extracted by mechanical pressing, using a hydraulic or screw press. The juice yield from expression process can be increased using various pre-treatments i.e. crushing, pulping, hydrothermal treatment, enzymatic treatment, and multiple pressings. Ohmic heating is a novel process wherein electric current is passed through foods leading to improvement in many processing applications. Carrot juice is popular due to its lower cost and high nutritive value compared to many other fruit juices. The effect of ohmic heating and 2-stage pressing on enhancing juice recovery from carrot, and optimization of the process variables are presented in this work.
