    摘要: Dihydrocoumarin produced technologically from coumarin by biotransformation is claimed together with related production variants that are carried out with the aid of isolated enzymes and/or microorganisms. Pure coumarin as well as coumarin isolated from a plant extract or coumarin-containing plant extracts can be used as starting materials. Selected strains of Saccharomyces, Arthrobacter, Pseudomonas, Bacillus, Basidiomycetes and Fusarium can be directly used for the biotransformation or can provide the enzymes required for the biotransformation. Preferred enzymes are coumarate and coumarin reductases. A production variant is additionally claimed which starts with coumarin and which, via o-coumaric acid or via intermediary dihydrocoumarin, leads to the subsequent melilotic acid which is subsequently dehydrated to dihydrocoumarin. The dihydrocoumarin obtained in this manner fulfils all criteria of a natural raw material which is why the product can also be used as a natural flavouring or for the production of or as a component of natural, nature-identical and synthetic flavours as they are typically used in baked goods, sweets, beverages, crèmes, cereal products and milk products.

    摘要: Stabilized aroma-providing components such as chocolate, tea or coffee aromas that are stabilized against loss or degradation of desirable flavor or sensory characteristics of its aroma during storage. The stabilizing agent is present with the aroma-providing component in an amount effective to chemically interact with compounds in the aroma-providing component to (a) provide increased amounts of desirable compounds that impart desirable flavor or sensory characteristics to the aroma or (b) reduce the amount of undesirable compounds that suppress desirable flavor characteristics or that contribute to or generate undesirable flavor or sensory characteristics in the aroma. The stabilizing agent preferably is a nucleophile that contains sulfur or nitrogen, such as sulfur dioxide, sulfites, compounds or substances that contain or generate sulfites, thiols, amines or amino acids, cysteine, gluathione or an enzyme. The stabilized aroma-providing component retains the desirable flavor and sensory characteristics of the aroma for a time period of at least six months to one year or longer.
