Mango pits effective against Listeria
Mango pits, usually thrown away after processing, could be used as a food preservative against the pathogen Listeria, a Canadian scientist said.
Tannins found in mango pits and grape seeds have been found effective against Listeria, a pathogen found in food that last year was linked to the deaths of 21 Canadians, University of Alberta researcher Christina Engles said.
By processing the kernels for their tannins, businesses have a way to completely utilize all fruit parts and therefore increase their profit, Engles said in a release from the university.
Mangos rank fifth among major fruit crops marketed worldwide. Listeria, a common bacteria found in soil, water, sewage, plants, and food, is responsible for listeriosis, a rare but potentially lethal food-borne infection.
