......my Australia, Sri Lanka, Canary Island..etc. memories Christopher Columbus called the papaya (bot. Carica papaya) native to Mexico and South America as the "fruit of the angels". The papaya, also known as the melon tree, likely has its roots in Mexico. At the beginning of the 16th century, the plant was already being cultivated by the Spaniards in the Antilles and the Philippines. Today the papaya is represented worldwide in the tropical and subtropical areas, whereby the main cultivation areas are Australia, India, Costa Rica and Brazil, in Africa the papaya is also represented. The trunk can grow up to 10 meters high, and the fruits normally weigh 3 to 7 kg. Papain, a special protein-splitting enzyme, is found in high concentrations in the papaya fruit. Papain is a rare, rich enzyme that is made up of more than 200 amino acids. A particularly high content of papain is found in the small, black, edible seeds and in the green, still unripe fruit.
