  1. Effects of high-intensity pulsed electric fields on the bioactive compounds stability and enzymes of broccoli juice

    Sánchez Vega, Rogelio
    This thesis doctoral was focused on evaluating the influence of HIPEF-processing parameters (electric field strength, treatment time and polarity) on bioactive compounds (chlorophylls, carotenoids, vitamin C and total phenolic compounds), minerals, amino acids and enzymes (myrosinase, polyphenol oxidase and lipoxygenase) of broccoli juice. Results of HIPEF-processed broccoli juice were compared with those of thermally treated (90 °C/60 s) and untreated juices. The HIPEF processing parameters significantly influenced the relative content (RC) of lutein, β-carotene, total phenolics (TP), vitamin C, minerals and amino acids, relative antioxidant capacity, as well as the RC of chlorophylls degradation compounds, the enzymes chlorophyllase, polyphenol oxidase, lipoxygenase and color difference (ΔE). However, polarity did not...
