“Onion, like fried onion or garlic”
Certified soft drinks flavour standard used to train professional soft drink tasters to recognize and scale the intensity of onion character.
Dimethyl trisulphide contaminates soft drinks through use of insufficiently-purified carbon dioxide gas for carbonation. It can also arise through microbiological spoilage, and – sometimes – through non-microbiological chemical reactions. It imparts an unpleasant swampy odour, reminiscent of onions, stagnant water or decaying vegetation.
