For cauliflower, microwave cooking yielded a phenolic content
equal to that measured for fresh vegetable. Other cooking methods
caused significant reductions. Mazzeo et al. (2011) analyzed
phenolic compounds in fresh, boiled and steamed cauliflower and
found that steaming increased the phenolic content by 17%.
Wachtel-Galor et al. (2008) analyzed phenolic compounds in fresh,
boiled, microwaved or steamed broccoli and cauliflower and found
that steaming produced higher concentrations of phenolic compounds
than those measured in fresh, boiled or microwaved
samples.
