Anthocyanins are water-soluble pigments responsible for the
attractive red, orange, blue and purple colours of most fruits and
vegetables. The increasing interest in anthocyanins is mainly due
to their attractive colour characteristics (Mazza & Miniati, 1993)
and health benefits (Konczak & Zhang, 2004). However, anthocyanin-
based colourants have limited applications in food industries
due to their high cost and low stability. Radish (Raphanus sativus
L.) anthocyanins have an intense red colour of high tinctorial
strength as well as comparable stability (Giusti & Wrosltad,
1996). A challenge of their application as food colourants comes
from the simultaneous inclusion of off-flavours derived from glucosinolates
present abundantly in cruciferous vegetables
