    Abstract: The present invention relates to use of at least one compound of formula (I) or stereoisomer thereof wherein R is linear or branched C1-C9 alkyl, linear or branched C2-C9 alkenyl, unsubstituted or C1-C3 alkyl-substituted C4-C8 cycloalkyl or substituted or unsubstituted aryl as aroma ingredient. The at least one compound of formula (I) may be used to impart an aroma impression which is reminiscent of a fruity note, green pear note, apple note, juicy—fruity note, styrax note pineapple note, dusty note, watery note, or a combination of two or more notes to a composition and also to enhance and/or modify the aroma of a composition. The present invention is further directed to a composition comprising at least one compound of formula (I) and (i) at least one aroma chemical different from compound of formula (I) and/or (ii) at least one non-aroma chemical carrier. It is also directed to certain compounds of formula (I) per se and processes of their preparation.

    Abstract: The invention describes an environmentally friendly, sustainable and cost-effective method for preparing astaxanthin diesters of the formula 1, in which astaxanthin of the formula 2 is doubly esterified with fatty acid chlorides of the general formula 3. For this purpose, compound 2 and 3 are reacted in an organic solvent in the presence of a nitrogen-containing base of the general formula 4. The invention further relates to the non-therapeutic use of the diester 1, in which R is a residue selected from the group consisting of C13-C19-alkyl, C13-C19-alkenyl, C13-C19-alkdienyl and C13-C19-alktrienyl, in human or animal nutrition and also the therapeutic use of the diester 1 prepared according to the method as a medicament and also as an ingredient in a medicinal preparation.

    Abstract: The invention relates to an improved process for isomerizing polyunsaturated non-aromatic compounds including acyclic conjugated polyenes and alicyclic conjugated polyenes. In particular it relates to an improved and safe process for forming a 11-E retinoid compounds in high yield by expending as few energy as possible and with avoiding at most possible side products or product mixtures. This is achieved by feeding at least one of retinoid compounds of formula 2 to 5, or at least one of retinoid compounds of formula 2 to 5 and retinoid compound of formula 1, an organic solvent and a photosensitizer into a reaction device and irradiating the thus obtained reaction mixture with visible monochromatic light, at least 90% of the power of said monochromatic light and at most 100% of said power being emitted in the range from 460 nm to 580 nm.
