Effects of electroplasmolysis treatment on chlorophyll and carotenoid extraction yield from spinach and tomato

► We applied electroplasmolysis and water-bath heating to tomato and spinach before extraction of colorants. ► Electroplasmolysis and water-bath heating increased extraction yield. ► Water-bath heating to 80 °C resulted in the highest beta-carotene extraction yield from spinach. ► Electroplasmolysis at 80 V/cm for 4 s resulted in highest beta-carotene and lycopene extraction from tomato. ► Electroplasmolysis at 60 V/cm for 8 s significantly increased extraction yield of chlorophylls from spinach.
