There are no tapuchim in Bereishis. The first mention of “tapuach” is in Shir Hashirim. And this is used by some as evidence that Shir Hashirim was written quite late, and was not written by Shlomo Hamelech.
As for apples, they were not known in the middle east at the time of matan torah. Maybe not even when Shir Hashirim was written, since Tosfos says the “tapuach” there is an esrog.
