Effect of Pef Pre-treatment and Extraction Temperature on the Recovery of Carotenoids from Tomato Wastes

In this work, the influence of pulsed electric fields (PEF) pre-treatment and extraction temperature on the recovery of carotenoid compounds from tomato peels, achieved after peeling of steam blanched whole tomato fruits, was investigated. PEF pre-treatments were carried out at different field strengths (E = 0.5–5 kV/cm) and total specific energy input (WT = 0.5-20 kJ/kg). The cell disintegration index (ZP) was used to identify the optimal PEF...
