Abstract:
A process for augmenting, enhancing or imparting an aroma in or to a fragrance composition comprising the step of intimately admixing with said fragrance composition an aroma augmenting, enhancing or imparting quantity and concentration of a product produced according to a process comprising the steps of:(a) preparing an aqueous nutrient medium as a first aqueous liquid phase;(b) preparing as a second phase an admixture of:(i) an organic phase which is a triglyceride of a fatty acid or a high molecular weight hydrocarbon; and(ii) a natural 2-decen-1,5-olide or a natural 2-dodecen-1,5-olide represented by the structural formula: ##STR81## wherein R is a member selected from the group consisting of methyl and n-propyl;(c) mixing said first aqueous phase and said second organic phase together with agitation to form a reaction medium;(d) feeding dextrose to said reaction medium at a rate of 5 to 72 g/L/hr in order to maintain said dextrose at a sufficient concentration; and(e) supplying the reaction mass with a sufficient amount of oxygen to maintain oxidative growth conditions to thereby achieve a fermentation reaction in the presence of a yeast capable of producing a mixture comprising a natural delta-lactone compound represented by the structural formula: ##STR82## wherein R is a member selected from the group consisting of methyl and n-propyl,and wherein said aqueous nutrient medium contains sufficient yeast, Saccharomyces cerevisiae to effect the fermentation reaction, and wherein the reaction product has a GLC profile of FIG. 1 or FIG. 6.
