摘要:
A two phase environmentally friendly fermentation process for producing high yields of &dgr;-decalactone and &dgr;-dodecalactone from the corresponding unsaturated starting materials is carried out under oxidative growth conditions using a saccharomyces species. The resulting products impart, augment and/or enhance the aroma and/or taste of consumable materials including foodstuffs, chewing gums, toothpastes, beverages, fragrance compositions, colognes and perfumed articles such as solid or liquid, anionic, cationic, non-ionic or zwitterionic detergents, fabric softeners, and hair preparations.

A two phase environmentally friendly fermentation process for producing high yields of .delta.-decalactone and .delta.-dodecalactone from the corresponding unsaturated starting materials is carried out under oxidative growth conditions using a Saccharomyces species. The resulting products impart, augment and/or enhance the aroma and/or taste of consumable materials including foodstuffs, chewing gums, toothpastes, beverages, fragrance compositions, colognes and perfumed articles such as solid or liquid, anionic, cationic, non-ionic or zwitterionic detergents, fabric softeners, and hair preparations.
摘要:
Described are optical isomers of (+) &dgr;-decalactone and (+) &dgr;-dodecalactone which impart, augment and/or enhance the aroma and/or taste of consumable materials including foodstuffs, chewing gums, toothpastes, beverages, fragrance compositions, colognes and perfumed articles such as solid or liquid anionic, cationic, nonionic or zwitterionic detergents, fabric softeners and hair preparations. The optical isomers are produced by means of a two-phase, environmentally friendly fermentation process for producing high yields of (+) &dgr;-decalactone and (+) &dgr;-dodecalactone from the corresponding unsaturated starting materials. The (+) &dgr;-decalactone substantially has the structure: with a very minor amount of isomer having the structure: and an optical rotation of +53.64° ((&agr;D20=+53·64° ) ). The (+) &dgr;-decalactone, which is the subject of the invention, has an enantiomeric excess percent of 95.6 ([&egr;&egr;%=95.6]).

摘要:
Described is a bioprocess for the high-yield production of food flavor-acceptable jasmonic acid and methyl jasmonate, as well as a novel jasmonic acid isomer produced thereby and organoleptic uses thereof. The process yields at least 5% of the “cis” isomer defined according the structure: (wherein R is hydrogen or methyl) or at least 5% of the “cis” isomer defined according to the structure: (wherein R is hydrogen or methyl). Compositions containing at least 98% of the isomer having the structure: with an optical rotation (&agr;D20) of +58° are novel. Compositions containing at least 98% of the isomer having the structure: with an optical rotation (&agr;D20) of +58° are also novel. The process of our invention comprises the cultivation under aerobic condition of one or more specific strain of Diplodia gossypina in a nutrient medium followed either by (1) isolation of the jasmonic acid product or (2) esterification of the jasmonic acid to form methyl jasmonate followed by the isolation of the methyl jasmonate and novel products produced by such process.
摘要:
A process for producing high yields of .gamma.-hexalactone and 2-pentanone from the corresponding hexanoic acid starting material is carried out with high amounts of oxygen and sugar in the presence of a mold microorganism. Fragrance compositions and foodstuff compositions are augmented and enhanced by the presence of the product compounds.
