“…Several studies have been conducted on phytochemicals and their changes due to plant parts, growing seasons, years of cultivation, and broccoli genotypes. The phytochemicals studied include glucosinolates, vitamins, phenols, and falvonoids (Balouchi et al, 2011;Jeffery et al, 2003;Koh et al, 2009;Naguib et al, 2012;Nath et al, 2011;Singh et al, 2007;Vallejo et al, 2003). However, information regarding sugars composition is limited to the floret tissue only .…”

Seasonal variation in the contents of sugars (fructose, glucose, and sucrose) in the floret, leaf, and stem of broccoli were studied in ten commercial broccoli cultivars. Plants were grown in the spring and fall seasons in 2011. In both seasons, glucose was the major constituent, comprising about 50% of the total sugar content in the floret and leaf tissue of most cultivars, whereas the broccoli stem showed an unusual pattern of accumulation. Sucrose exhibited greater cultivar dependency as well as seasonal variation compared to fructose and glucose in floret and leaf tissues. The floret tissue had a higher total content of sugar in the spring compared to the fall due to an increase in glucose and fructose. However, most of the leaf and stem tissues of broccoli had a higher total sugar content in the fall compared to the spring. Furthermore, stem and leaf tissues possessed a relatively higher total sugar content compared to floret tissue in both seasons. 'Grandeur' broccoli contained a significantly greater amount of total sugar in both floret and leaf tissues in both seasons, whereas 'YuDoRi No.1' broccoli exhibited the highest total content of sugar in stem tissue. At overall, the results showed significant influences of genotype, plant part and growing season on sugar content in broccoli.

“…They possess strong antioxidant activity due to their ability to scavenge reactive oxygen species and inhibit oxidative stress (Rice-Evans et al, 1995;Pourcel et al, 2007). Variation in the amounts of these phytochemicals depends upon factors such as cultivar genotype, developmental stage, growing conditions, season, soil properties, and post-harvest storage conditions (Kurilich et al, 1999;Vallejo et al, 2002;Jeffery et al, 2003;Singh et al, 2007;Nath et al, 2011;Samec et al, 2011;Samec et al, 2013).…”

Florets, leaves, and stems of twelve commercial broccoli cultivars grown in the spring and fall seasons at the National Institute of Horticultural and Herbal Science (NIHHS), Rural Development Administration (RDA), Suwon, South Korea were evaluated for glucosinolates, vitamin C, total phenol, and total flavonoid contents and antioxidant activity. The levels of all phytochemicals and antioxidant activity were significantly influenced by cultivar (C), plant part (P), and growing season (S). Among the glucosinolates, glucoraphanin and glucobrassicin were the major constituents. The highest total glucosinolate content was found in the florets of plants grown in both seasons. Phenols and flavonoids were highest levels in leaves, while vitamin C was highest in stems, suggesting that broccoli leaves and stems may be good sources of such phytochemicals. The levels of all phytochemicals were generally higher in florets in the spring than in the fall, but were higher in leaves and stems during the fall than the spring. Furthermore, higher cultivar-dependent and tissue-dependent variation was observed in the spring than in the fall. Total phenol content exhibited a strong positive correlation (r = 0.674**) with antioxidant activity, followed by total flavonoid content (r = 0.497**), indicating their significant contribution to total antioxidant activity.

“…italica) is a Brassica genus vegetable with high nutritional value due to its richness in vitamins, antioxidants, anti-carcinogenic substance and health promoting phytochemicals such as glucosinolates (Nestle 1998, Yuan et al 2010. But the previous studies revealed that levels of ascorbic acid, glucosinolates and flavonoids have been significantly influenced during harvest, handling and storage (Vallejo et al 2003, Nath et al 2011). …”

“…Composition of the gas inside the package is changed by respiration of fruits, decreasing O 2 level while CO 2 increases during storage. Storage of broccoli in MAP reduced weight loss and respiration rate, maintained ascorbic acid, total antioxidant activity, glucosinolate contents and visual quality and thus increased postharvest life in cold or ambient storage (Nath et al 2011, Serrano et al 2006, Jia et al 2009). …”

Broccoli is rich in health-promoting compounds such as ascorbic acid and glucosinolates. However, amount of such compounds inevitably decrease along with the storage. This study was conducted to investigate the effects of 1-methylcyclopropene (1-MCP) and Modified Atmosphere Packaging (MAP) treatments alone or in combination on postharvest life and quality of broccoli heads during cold storage. MAP and 1-MCP+MAP significantly reduced weight loss, delayed surface color changes and chlorophyll breakdown, maintained visual quality, ascorbic acid, total phenol, soluble solid contents and titratable acidity compared with control as well as 1-MCP treatment. In 1-MCP plus MAP treated florets, approximate 47% and more chlorophyll and 24% more total phenol contents were found compared to control florets. 1-MCP plus MAP application better performed in maintaining the quality of broccoli florets during 28-day-storage. Overall results revealed that combined treatment can be recommended for commercial broccoli storage at 0 °C.
