JECFA concluded that flavouring agents Nos 2299, 2303 and 2306 all exceeded their respective thresholds of toxicological concern. The structural analogue proposed to complete the evaluation of these three flavouring agents was acetaldehyde (No. 80); however, JECFA considered that the use of acetaldehyde (No. 80) as a structural analogue in this safety assessment would require further evaluation.
