REVIEW - INNOVATIONS IN PHYSICAL MODULATE D TREATMENTS FOR PRESERVED POSTHARVEST QUALITY OF FRUITS AND VEGETABLES .2. CYCLICAL HEAT-TREATMENTS

In the second part of this paper, ciclycal heat treatments are describ ed, particularly intermittent warming or cooling and fluctuating tempe rature during cold storage of fruits and vegetables. These heat treatm ents have been demonstrated to eliminate or alleviate postharvest loss es of quality, generally associated with chilling injuries, pathogen i nfections and senescence. The biochemical and physiological basis of t hese ciclycal heat treatments and their effects on postharvest fruit q uality are discussed in this review, paying special attention to the S panish contributions on this topic.
