What You Need to Know
Allyl isothiocyanate (AITC) released from sinigrin glucosinolates via myrosinase enzyme activity disrupts microbial cell membranes. Secondary inhibition occurs through lowered water activity and pH modulation.
Essential for preserving oil-based pickles (achar) without refrigeration while developing characteristic pungency.
