than that of pure mimosine, the high PPO inhibitory activity of
LSEP was plausibly caused by a supplementary action of other
compounds with mimosine. Recently, catechin (Nirmal & Benjakul,
2009a) and ferulic acid (Nirmal & Benjakul, 2009b) were shown to
inhibit PPO from Pacific white shrimp in a dose dependent manner.
Therefore LSEP could serve as an alternative inhibitor for PPO from
Pacific white shrimp.
