aA year later, the identification, in heated acidified beer, of (E)-2-nonenal, by Jamieson and Van Gheluwe (1970), as the molecule responsible for cardboard flavour, was considered a breakthrough in beer flavour research. 一年后,证明,在激昂的酸化的啤酒, (E) - 2-nonenal,由Jamieson和范...
Although lipid autoxidation in the boiling kettle is a key determinant of the cardboard flavor of aged beers, recent results show that mashing is another significant source of wort nonenal potential, the well-known indicator of how a beer will release (E)-2-nonenal during storage. Although unst...
