[Effect of different cooking treatments of Mucuna beans on its L-Dopa content].

The main limiting factor in the consumption by humans of the velvet bean (Mucuna) is its relatively high content of L-Dihydroxyphenylalanine (L-Dopa), with levels as high as 9%. Conventional cooking methods used to transform raw velvet bean into an edible product are not sufficiently effective in reducing the levels of L-Dopa in adequate processing time. In this report, Mucuna beans were cooked by microwave, utilizing vapor and in water solutions at pH 3, 6, 7, 9 and 11.
