Pineapple Residues: Sustainable Feedstock for Chemicals and Value-Added Products

The major part of food waste in our surroundings is produced due to the processing of fruits and vegetables. To recycle this waste, a considerable amount of money is required and as a result, these are either dumped in open spaces or else burned which tends to intensify the pollution problems. This article provides information regarding the potential of pineapple waste including the left-over peels, core, stem, and crown portions to generate value-added compounds, and the techniques that can be used to extract these compounds from the by-products have also been assembled from literature. The highly nutritious profile of pineapple waste including its high carbohydrate content makes it a suitable substrate for the manufacture of important chemicals. Such utilisation of waste would be immensely helpful in the reduction of environmental issues and would also provide an innovative way to manufacture useful compounds out of the waste.
