Hazelnut: Explorations toward the Biocatalytic Synthesis of its Aroma Precursor
ChemBioChem, EarlyView.This article proposes a biosynthetic route for synthesizing filbertone, the principal flavor compound of hazelnut, through a multienzyme cascade. The pathway uses D‐amino acid oxidase, threonine deaminase, and a regioselective transketolase from Geobacillus stearothermophilus to produce a sustainable, natural hazelnut aroma precursor, addressing ...
