Instead of throwing it away, calcium-rich milkfish bone can be used as an ingredient for making a desert.
The making of polvoron out of bangus bones was pioneered in 2000 by Dean Laurentina Calmorin of the Northern Iloilo Polytechnic State College in Estancia, Iloilo. She successfully incorporated powdered milkfish bones in making polvoron, a sweet and powdery desert that is conventionally made of flour, milk powder, sugar and butter.
