Fast and Slow Roasting of Alcohol- and Honey-infused Coffee Blends: A Comparative Study of PAH and N-PAH Emissions

open access: yesAerosol and Air Quality Research, 2023
Polycyclic aromatic hydrocarbon (PAH) and nitrated PAH (N-PAH) emissions during coffee roasting were investigated. The fast roasting of green coffee resulted in mass and toxic concentrations approximately 1.6 and 3.2 times higher than in the slow ...
