Storage in high-barrier pouches increases the sulforaphane concentration in broccoli florets

Sulforaphane is a phytochemical that is usually found in cruciferous vegetables and is known to have a depressive effect on gastric cancer. Preliminary investigations showed that the sulforaphane concentration in broccoli (Brassica oleracea var. italica) florets increased under anoxia. Therefore, in the present study, we examined the effect of different atmospheric conditions on the sulforaphan...

Hot air treatment delays senescence and maintains quality of fresh-cut broccoli florets during refrigerated storage

A postharvest treatment with hot air (48 C during 3 h) was applied to fresh-cut broccoli to investigate its effect on quality and senescence during storage at 0 C. The treatment delayed yellowing as evidenced by lower decrease of Hue values during storage. After 21 days of storage, treated broccoli had chlorophyll content approximately 40% higher than controls. The treatment did not affect eith...

Heating decreases epithiospecifier protein activity and increases sulforaphane formation in broccoli.

Sulforaphane, an isothiocyanate from broccoli, is one of the most potent food-derived anticarcinogens. This compound is not present in the intact vegetable, rather it is formed from its glucosinolate precursor, glucoraphanin, by the action of myrosinase, a thioglucosidase enzyme, when broccoli tissue is crushed or chewed. However, a number of studies have demonstrated that sulforaphane yield fr...

Gas Chromatography/Mass Spectrometry Method for the Determination of Sulforaphane and Sulforaphane Nitrile in Broccoli

Phytochemicals, especially the secondary metabolites synthesized by plants, play key roles in human nutrition, health, wellness, and disease prevention. Some phytochemicals may be harmful to human health. For example, two closely related 4-methylsulfinylbutyl glucosinolate [glucoraphanin] hydrolysis products from broccoli (Brassica oleracea L. var. Botrytis), 1-isothiocyanato-4-(methylsulfinyl)...
