No, because acetone has been identified as the organic volatile compound that appears on the breath of the fasting due to subtle changes in metabolic liver function due to dietary stress, historically referred to as the ‘odour of sanctity’ of antiquity.
This is something Catholics believe in and non-Catholics don’t normally investigate. It is one of those issues that has to be answered with a resounding maybe. Would a residue of acetone be able to overcome the otherwise normal accumulation of stinky compounds like putrescine? Not even religious ecstasies could do that. In general, God seems to accommodate willingness to believe with phenomena that addresses it. Since it is not an evangelical trope, God does not bother in that milieu.
I’m kind of surprised that the biblical reference of the saints as being a spiritual fragrant offering to God the Father by God the Son isn’t well noted here.
