According to the guidelines of the German Food Book products of two species
of the genus Helix, H. pomatia and H. aspersa, may be labelled as vineyard
snail, but not the commercially important species of H. lucorum, In the pr
esent study the quality and sensory properties of H. pomatia, H. lucorum an
d Achatina species were compared by sensory assessment and measurement of t
exture and colour. DNA-analysis (PCR-RFLP) was used for differentiation of
species. The sensory properties of the 3 species were found to be very simi
lar, and not to be suited for differentiation. In contrast to this finding,
the physical tests revealed some differences between species. By PCR-RFLP
DNA-fragment patterns were obtained allowing unambiguous differentiation of
the 3 species.
