It was proposed that astaxanthin and/or canthaxanthin in salmon muscle binds with one β-ionone ring to a hydrophobic binding site which exists on the surface of actomyosin. The binding of carotenoids to actomyosin is not specific. The hydroxyl and keto groups of β-end group intensify the binding strength of carotenoids to actomyosin.
