Agri-food industries generate enormous amounts of fruit and vegetable processing wastes, which opens up an important research area aimed towards minimizing and managing them efficiently to support zero wastes and/or circular economy concept. These wastes remain underutilized owing to a lack of appropriate processing technologies vital for their efficient valorization, especially for recovery of health beneficial bioactives like dietary fibers. Dietary fiber finds wide applications in food and pharmaceutical industries and holds high promise as a potential food additive and/or as a functional food ingredient to meet the techno-functional purposes important for developing health-promoting value-added products. Based on this, the present review has been designed to support ‘zero waste’ and ‘waste to wealth’ concepts. In addition, the focus revolves around providing updated information on various sustainability challenges incurred towards valorization of fruit and vegetable wastes for extraction of health promoting dietary fibers.

来自未充分利用的植物资源的膳食纤维——水果和蔬菜废物利用的积极方法

农业食品工业产生大量的水果和蔬菜加工废物，这开辟了一个重要的研究领域，旨在最大限度地减少和有效管理它们，以支持零废物和/或循环经济概念。由于缺乏适当的加工技术，这些废物仍未得到充分利用，这对其有效价值至关重要，尤其是对健康有益的生物活性物质（如膳食纤维）的回收。膳食纤维在食品和制药行业得到广泛应用，并且作为潜在的食品添加剂和/或功能性食品成分具有很高的前景，可满足对开发促进健康的增值产品很重要的技术功能目的。基于此，本次审查旨在支持“零浪费”和“变废为宝”的概念。此外，
