Montalcini, an FAO goodwill ambassador since 1999, died on 30 December in Rome.
A statement by the FAO, copied to the Ghana News Agency on Tuesday said: "Professor Montalcini was recognized internationally as one of the world's finest minds. At FAO, we knew her as a wise and gracious friend, a tireless advocate for a hunger-free world.
"FAO will always be grateful to her for helping to keep the drive to end hunger, malnutrition and extreme poverty high on the international agenda".
