A Critical Review on Tropical Fruits Peels as Eco Enzyme: A Case of Indonesian Exotic Fruits

Abstract

Indonesia has a tropical climate rich in exotic fruits, such as pineapples, bananas, oranges, papaya, mangoes, watermelons, and pomegranates. Apart from its abundant production, these fruits also have parts of the fruit that are rarely used, such as seeds and peels. The peel of exotic fruits can be used as an eco-enzyme because of its enzyme content. Eco-enzymes are a type of natural compound that can usually be extracted from fruit peel or waste. Eco-enzymes are vinegar made by fermenting food waste with sugar to form alcohol. This review focuses on the potential use of exotic fruit peels and the enzymes they contain, which are used as ecoenzymes. Eco-enzyme production reduces the accumulation of organic waste and has several other benefits, including cleaning floors, equipment, etc. Extensive research in the industrial sector must also be carried out to improve the nutritional and functional potential of the peel of this exotic fruit.
