In this study,
similarly processed pennywort juices with sugar addition were investigated
for characteristics of the aroma compounds by GCMS
using solid phase microextraction (SPME). Since these juices
present bitter flavor, sugar could conceal this taste and develop better
perception for consumers. Alex and others (2003) mentioned
that sugar content in stored litchi juice may vary depending on the processing of the juice, and this may have altered the color and flavor
of the original juice.
