Broccoli (Brassica oleracea L.) is consumed fresh in ready-toeat salads or cooked, popular owing to its high nutritional value associated with high levels of ascorbic acid, anticarcinogenic, and antioxidant compounds (King and Morris, 1994). Broccoli heads, composed by a number of immature floral buds (florets), are harvested totally immature and only have 2–3 days shelf-life at 20◦C (Wang, 1977). Broccoli florets have a shorter shelf-life than intact products due to mechanical damage that can induce high rates of respiration and metabolism, during which many chemical reactions occur. Some of these reactions, if not controlled, can lead to rapid senescence and undesirable quality loss, expressed as surface dehydration, loss of green color and stem firmness, opening of florets, development of undesirable odors, and soft rots (Berrang et al., 1990; Forney et al., 1993). Approaches to extend the shelf-life of intact or fresh-cut broccoli are to control senescence
