No one has posted exactly what kind of aldehyde is in pears, so I can't answer that. The difference between natural and synthetic is often chirality, and real formaldehyde isn't chiral.
For example natural vitamin E is d-alpha tocopherol, and synthetic is an even mix of d- and l-alpha tocopherol. The l- version is useless.
