In conclusion, our data showed that a postharvest application of
sucrose significantly extended shelf life, inhibited chlorophyll
degradation and improved the antioxidant capacity of broccoli
florets. The contents of total glucosinolate and sulforaphane in
broccoli florets were better retained in sucrose-treated samples.
Total and reducing sugars decreased during postharvest senescence,
with lower values in control samples. These results imply
that sucrose treatment has a potential application in nonrefrigerated
retail displays to improve shelf life, maintaining
quality and improving the health benefit of broccoli florets.
