However, withering by microwave for 2 min at 900 W inactivated myrosinase
completely and produced sayur asin with a sinigrin
concentration of 11.4 μmol/10 g dry matter after 7 days
of fermentation. This high power-short time pretreatmentof B. juncea leaves contributes to the production of sayur
asin containing significant levels of health-promoting glucosinolate.
In this study, the effect of myrosinase activity
during Brassica fermentation was quantified, and optimised
production methods were investigated to retain glucosinolate
in the final product.
