Allyl isothiocyanate (AITC) is the major component in essential oils of cruciferous plants, such as black mustard seeds (Brassica nigra), brown mustard seeds (Brassica juncea), cabbage (Brassica oleracia), and horseradish (Armoracia rusticana) [101,102]. AITC is a specific compound from the isothiocyanate (ITC) group that has been shown to have bactericidal, bacteristatic, and antifungal activities. AITCs are released upon disruption or injury of plant tissue due to hydrolysis of glucosinolates by cell wall-bound myrosinase [103,104]. Other important properties of ITC compounds are their high volatility, extreme pungency, and low water solubility.
