摘要/Abstract:

The development and supply of sustainable and healthy food ingredients is one of the central social challenges of our time. The presentation will focus on recent approaches for the fermentative production of natural flavor compounds by mushrooms. A wild strawberry-like flavor is formed by surface cultures of the fungus Wolfiporia cocos grown on black currant pomace, and an intense anise-like aroma is emitted by submerged cultures of Pleurotus sapidus cultivated on citrus side streams. Surprisingly, the enzyme accepted thiols as substrates as well, which allowed for the production of meaty aroma compounds. The formation of coconut-like, sweetish, and buttery smelling diastereomeres of dihydromenthofurolactone and its corresponding C3-unsaturated lactone by the fungus Cystostereum murrayi is an example for the de novo formation of flavor compounds by mushrooms.
