This study investigated the variation in cyanide and amygdalin content in ginkgo fruits depending on thermal treatment methods. The fruits were heated by boiling and roasting. The thermally treated fruit samples were compared with non-treated fruit samples by measuring cyanide and amygdalin content. The cyanide content of ginkgo fruits was decreased by thermal treatment, whereas boiling decreased it more than roasting. As amygdalin was not detected in the samples, ginkgo fruits were artificially injected by amygdalin, which was slightly decreased by thermal treatment. As the cyanide content is small and can be further reduced by thermal treatment, consuming ginkgo fruits after cooking may not cause a health problem.
