Effect of combined treatment with hot air and UV-C on senescence and quality parameters of minimally processed broccoli (Brassica oleracea L. var. Italica)

Influence of combined hot air and UV-C treatment on the antioxidant system of minimally processed broccoli (Brassica oleracea L. var. Italica)

“…Therefore, the high POX activity detected in control samples could indicate higher tissue damage. The delay of POX activity increment in treated samples would be associated to less deterioration as it was detected in the previous work (Lemoine et al, 2008).…”

“…In a previous work, we had shown that a combined treatments with hot air (48 C during three hours) and UV-C (8 kJ m À2 ) delayed degreening by slowing down chlorophyll degradation and maintained organoleptical quality of minimally processed broccoli florets (Lemoine et al, 2008). Taking into account the importance of antioxidant system in preserving plant tissue integrity and also their potential benefits in human diet, in this work we analyzed the effect of such combined treatment on several enzymatic and nonenzymatic mechanism related to maintenance of antioxidant status.…”

“…In a previous work, we had demonstrated that a treatment at 48 C for 3 h combined with a UV-C dose of 8 kJ m À2 rendered an optimum delay of postharvest senescence of minimally processed broccoli at 20 C (Lemoine, Civello, Chaves, & Martínez, 2008). The objective of the present work was to analyze the effect of the influence of such combined treatment on several chemical components and related enzymes contributing to the antioxidant machinery of minimally processed broccoli stored at 20 C.…”

6-Benzylaminopurine Delays Senescence and Enhances Health-Promoting Compounds of Harvested Broccoli

“…Harvesting and the following processing cause severe stress, hastening the appearance of senescence symptoms. 3 The effect of different storage methods on extending shelf life and improving visual quality and nutritional quality of broccoli has been widely investigated. 4,5 Glucosinolates as an important class of secondary metabolites have gained particular interest as potential anticancer and chemopreventing agents.…”

Environmental Friendly Sanitation to Improve Quality and Microbial Safety of Fresh-Cut Vegetables

“…Combined heat treatments with UV-C were applied to fresh-cut processed broccoli (Brassica oleracea L.) florets to investigate their effects on several quality and senescence parameters. Heat treatments and UV-C radiation have been utilized to extend storage quality of fresh-cut products (Lemoine et al, 2008).…”
