Currently used in only seven cosmetic products, its highest reported concentration of use was 0.5% in perfumes. The characteristic benzaldehyde odor of oil of bitter almond occurs because of trace amounts of free benzaldehyde formed by hydrolysis of the glycoside amygdalin. Benzaldehyde is a versatile intermediate because of its reactive aldehyde hydrogen, its carbonyl group, and the benzene ring. Benzaldehyde is formed from phenylpyruvic acid, derived by the aminotransferase activity on phenylalanine, in the presence of high levels of Mn2+, and contributes to the generation of flavor compound during cheese ripening.
