Abstract
Diplotaxis erucoides is a wild edible plant (WEP) of the Brassicaceae family, growing as a weed in Mediterranean countries. It contains glucosinolates, which are hydrolyzed by myrosinase rendering isothiocyanates; these compounds are responsible for its characteristic aroma and flavor, similar to that of mustard or wasabi. The aim of this study was to characterize the Diplotaxis erucoides plant by analyzing its volatile, sugar, organic acid, and sensory profiles. This information will be essential to decide whether it is possible to develop sustainable and healthy alternatives to commercial mustard and wasabi using this WEP. Two Diplotaxis-based products were prepared one cream and one mayonnaise. Allyl isothiocyanate represented more than 80% of total content of volatile compounds in the leaves, pods and stems. The sugar and organic acid content of Diplotaxis and its based products were very low. The Diplotaxis products were characterized by having intense Diplotaxis odor/aroma, herbaceous flavor and long aftertaste, but lacked some pungency. Diplotaxis erucoides is a sustainable and healthy option to produce herbaceous and pungent sauces.
