Suppose you are a banana exporter from Kerala. Recently, you acquired a contract that allows you to export your produce into Europe. As a fruit exporter, you realize that your consignment cannot be shipped from Kerala because your variety of banana has a very short shelf life because it releases more ethylene than the other varieties (Ethylene causes fruits to ripen quickly). How do you propose to extend the shelf life of your produce without going bananas? |
