White cabbage outer leaves have noted to contain various beneficial glucosinolates. Several techniques have been used to extract these compounds with various degrees of success. However, it might be possible to enhance the extraction efficiency of these (and other) compounds through structural modification of the cabbage matrix. In this study, the effect of structural modification via the use of ultrasonic pretreatment on the amount of total glucosinolates extractable from cabbage outer leaves was investigated. Use of ultrasonic pretreatment prior to extraction led to more structural damage and higher content of extractable glucosinolates than in the case where no pretreatment was applied.
