- Abstract
Featured Application: This review provides a collection of information about the application of plant-based waste for the extraction of dietary fiber using different extraction methods. Favorable extraction techniques and optimal extraction conditions can, depending on the plant resources, facilitate the investigation for future researchers and the industry. The amount of waste generated by the production of food products has increased over the years, presenting economic and environmental problems. To minimize these problems, it is necessary to valorize food waste in order to explore its further utilization in the food industry and also in other industries. Such waste usually represents a valuable raw material in terms of dietary fibers or bioactive components. Dietary fibers, especially pectin, are usually derived from apple pomace or citrus peel. Currently, sources of dietary fibers include novel food waste streams and by-products. Also, the utilization of novel extraction techniques is in demand to limit conventional processes. This review provides information about the conventional and innovative extraction approaches for dietary fibers from different food wastes. The extraction of these fibers depends on the materials used and the extraction conditions, such as temperature, solvents, time, pH, and liquid/solid ratio. Novel green techniques may ensure an increase in fiber yield and better quality, as well as a reduction in operating time and toxic solvents.
