US 4,542,097 A · Production of gamma-lactone, rich flavor additives by Pityrosporum species cultured on lipid rich substrates

Abstract

Novel odor-flavor materials and methods for producing the same are disclosed comprising a mixture of various gamma-lactones. In the preferred embodiment, a member of the genus Pityrosporum is cultured on a culture medium and is stimulated to produce a gamma-lactone containing flavor-fragrance mixture through its incubation with a lipid rich precursor. The preferred species for use in producing these gamma-lactone containing materials are P. canis, P. pachydermatis, P. orbiculare and P. ovale. The preferred lipid-rich materials include triolein, sebum, lecithin, oleic acid, and SAB with human sebum, and Tween-80. The resulting gamma-lactone rich products comprise the following lactones: gamma-hexa, gamma-hepta, gamma-octa, gamma-nona, gamma-deca, gamma-undeca, and in the case of P. canis, gamma-dodecalactone. The resultant flavor-fragrance product is all natural, exhibiting extremely pleasing taste and/or flavor characteristics.

Dependent claims

A method of making gamma-lactone containing flavor-fragrance products comprising the steps of:

(a) providing a substantially sterile culture medium;
(b) combining with said culture medium a lipid rich precursor-stimulant means for stimulating production of gamma-lactone flavor-fragrance products during succeeding incubation;
and
(c) incubating said medium combined with said lipid rich precursor-stimulant means with a biologically active inoculant consisting essentially a member of the genus Pityrosporum, said member being P. orbiculare.
