It is known that volatile terpenes (_-terpinene, _-myrcene,
_-caryophyllene, farnesene and _-humulene) are the compounds
which are responsible for the bitter taste as demonstrated
previously Rosenfeld et al. (2002). However, recently
Czepa and Hofmann (2003) showed that polyacetylenes such
as falcarinol and falcarindiol-3-acetate are the most important
bitter taste indicators in carrots. _-caryophyllene was
found to be responsible for terpene-like, spicy, woody aroma
in carrots (Kjeldsen et al., 2003).
