In industries where non-denatured alcohol is used for food products manufacturing (spirits, flavors and extracts, vinegar, food dyes, candy glazes, yeast, various sprays, animal-feed supplements, etc), quality is critical. Food grade alcohol is assessed by organoleptic and analytical chemical methods to check it is neutral and free of foreign odors and tastes.
With our HERACLES Fast Gas Chromatography Electronic Nose you can analyze food grade ethanol to verify its purity and sensory conformity.
For an analysis aimed at checking the purity (ethanol percentage) of ethanol used for spirits production, several batches of ethanol were tested with HERACLES instrument. In particular, contaminated ethanol samples with noticeable off-odors were compared to odorless ethanol representing the reference quality.
