摘要:
Optically active .gamma.-decalactone is produced by culturing a microorganism capable of hydrolyzing castor oil and effecting .beta.-oxidation of the resulting hydrolysate in the presence of castor oil or castor oil hydrolysate and a co-oxidant. The resulting .gamma.-hydroxydecanoic acid is lactonized to form .gamma.-decalactone.

Described is the use of sclareolide in augmenting or enhancing the organoleptic properties of foodstuffs whereby:(i) richness and creaminess is added to low fat ice cream by admixing therewith the sclareolide;(ii) sweetness of foodstuffs and beverages caused by non-neutrative sweetners e.g., aspartame, is enhanced by admixing with the non-neutrative sweetener, prior to addition to the beverage of foodstuff, sclareolide;(iii) bitter nuances imparted by the use of potassium chloride in salt substitutes are substantially covered by means of admixing such salt substitutes with sclareolide;(iv) saltiness of foodstuffs caused by such salts as sodium chloride is enhanced (and the required concentration of such salts in such foodstuffs from an organoleptic standpoint is thereby reduced) by means of admixing with the salt, prior to addition to the foodstuff, sclareolide; and(v) mouthfeel is imparted to, and aesthetically pleasing flavor nuances are enhanced in textured seafood products such as surimi by means of addition to either the textured seafood product itself or to a flavor enhancing or augmenting product which is then added to the seafood product, sclareolide.
