This entry replaces the previous Act c 1 entry. The Act c 1 entry was removed from the database, as Act c 1 was renamed to Act d 1 in 2007. The new name reflects the updated taxonomy of kiwifruit species, separating Actinidia deliciosa from Actinidia chinensis. In contrast to A. deliciosa, A. chinensis contains only low amounts of actinidin.
