Up to comparatively recently orange peel and the associated residual remnants of membranes resulting from juice extraction represented a significant disposal problem, especially in those regions where orange cultivation is a major industry. However, recent research has demonstrated that orange peel waste represents a potentially valuable resource that can be developed into high value products. These developments are critically reviewed in this article. This includes a summary of the chemical composition of the substrate and an assessment of the range of applications in which the peel is deployed. Utilization as a substrate to produce animal feed, fertilizer, essential oils, pectin, ethanol, methane, industrial enzymes, and single cell protein is discussed. The applications described together with those that will no doubt be developed in the future, represent great opportunities to harness the economical benefit of this agro-industrial waste and to develop even more efficient and sustainable systems. A scheme of integrated utilization of orange peel in a biorefinery approach is discussed together with some prediction of further necessary research.
直到最近，橙皮和由此产生的榨汁过程中残留的膜仍然是一个严重的处理问题，尤其是在那些橙种植是主要产业的地区。然而，最近的研究表明，橙皮废料是一种潜在的有价值资源，可以开发成高价值产品。本文对此进行了批判性的回顾。这包括对基质的化学成分的总结和对皮在各种应用中的部署的评估。将其用作生产动物饲料、肥料、精油、果胶、乙醇、甲烷、工业酶和单细胞蛋白的基质的利用进行了讨论。所描述的应用，以及无疑将在未来开发的应用，为利用这种农业工业废物的经济利益和开发更高效和可持续的系统提供了巨大的机会。本文还讨论了在生物炼制方法中综合利用橙皮的方案，并对进一步的必要研究进行了一些预测。
