“…4-Ethyloctanoic acid (EOA) occurs in the root oil of the Costus plant, flue-cured virginia tobacco, aged Italian cheese, sheep cheese, goat cheese, etc., and it has waxy, fatty, creamy, moldy, sour sweaty, cheesy odor with animal-like nuances [6]. Benzyl alcohol (BA), phenethyl alcohol (PEA), phenylpropanol alcohol (PPA), cinnamic alcohol (CA) and the esters derived from these alcohols are very important flavor compounds and are often used in formulating food flavoring and fragrance compounds, but the esters derived from 4-ethyloctanoic acid and the four alcohols are not been reported up to now.…”
