Fruit waste utilisation

Processing of fruits produces two types of waste - a solid waste of peel/skin, seeds, stones etc -a liquid waste of juice and washwaters. In some fruits the discarded portion can be very high (eg mango 30-50%, banana 20%, pineapple 40-50% and orange 30-50%). Therefore, there is often a serious waste disposal problem, which can lead to problems with flies and rats around the processing room, if not correctly dealt with. If there are no plans to use the waste it should be buried or fed to animals well away from the processing site.

This brief provides information on different ways to use fruit waste for making candied peel, oils, pectin, reformed fruit pieces, enzymes, wine and venigar.
