Agrotechnology & Food Innovations has developed a special chloride packaging material jointly with the Kasersart University in Bangkok, Thailand. The film prevents the early formation of black spots on bananas, a welcome development for sweet banana growers.
Fruit sellers find it difficult to convince their customers that their spotty bananas are still alright to eat. The customers would rather have an evenly yellow banana. “We have tried all sorts of different packaging, but in the end the best was a film that allows just enough oxygen and just enough carbon dioxide through.” The low oxygen content delays the spot formation, but the fruit itself produces carbon dioxide and this must be able to escape otherwise the banana will ‘suffocate’. The higher humidity caused by the packaging has no detrimental effects.
The chloride film is suitable for bulk transport of bananas in sacks and also for covering bananas in the supermarket. The packaging has been tested on the sweet dessert banana Musa cavendishii, which is widely grown in Indonesia, Burma, India, Colombia and Brazil. | H.B.
