An enzymatic hydrolysis of a glycosidic substrate containing at least one of the said precursors is performed with at least one enzyme chosen in accordance with the structure of the said precursor, to liberate the corresponding monoglycosides by cleavage at a glycoside bond, and, in a second stage, an enzymatic hydrolysis of the product of the first stage is performed with at least one enzyme other than or identical to that/those of the first stage and designed to liberate the aroma components and aromas by cleavage of the aglycone-carbohydrate linkage bond. A vegetable material derived from a fruit such as grape or an aromatic or flowering plant, as well as their derivatives and by-products, is chosen as a glycosidic substrate. Terepenols such as geraniol, linalol, nerol and the like, terpene polyols and alcohols such as phenyl ethyl alcohol and benzyl alcohol, or the like, are obtained, in particular, as aroma components or aromas.

Process for obtaining aroma components and aromas from their precursors

.beta.-glucosidase from filamentous fungi, and uses thereof

A method is disclosed for obtaining aroma components and aromas from their glycosidic precursors containing a .beta.-apioside with the use of .beta.-apiosidase.
