Vanilla pod seeds. Coloured scanning electron micrograph (SEM) of the inside of a vanilla pod, showing black seeds in parenchyma tissue. Vanilla flavouring is derived from the seeds and pods of orchids of the genus Vanilla (such as Vanilla planifolia). The chemical compound that produces the characteristic aroma and flavouring is vanillin. Vanillin is synthetically manufactured for large-scale use, but this synthetic version lacks some of the other organic constituents found in natural vanilla extract.
