In the Middle East and North Africa, dates are a traditional and economically valuable crop, playing an essential role in people's daily diets. Date fruit production and related processing industry generate a large quantity of waste; for illustration, the date juicing industry produces roughly 17-28% Date press cake (DPC), which is mainly discarded in open lands and drains. Considering the generation volume and the nutrient content of DPC, this organic by-product stream can be valorized through the production of a wide range of products with a great market appeal, such as volatile fatty acids, activated carbon, organic acids, etc. To provide an insight into the feasibility of the application DPC as a green precursor for various chemical and biological processes, the chemical and nutritional composition of dates and DPC, an overview of the date processing industries, and common practices conducted for DPC valorization addressed and thoroughly discussed, in this review.
在中东和北非地区，枣椰是一种传统且经济价值高的作物，在人们的日常饮食中起着重要作用。枣椰的生产和相关加工业会产生大量的废弃物；例如，制枣汁产业会产生大约 17-28%的枣压榨饼（Date press cake，DPC），这些 DPC 主要被丢弃在空地和排水渠中。考虑到 DPC 的产生量和营养成分，这种有机副产物可以通过生产各种具有巨大市场吸引力的产品来增值，例如挥发性脂肪酸、活性炭、有机酸等。为了深入了解 DPC 作为各种化学和生物过程的绿色前体的应用可行性，本文综述了枣椰和 DPC 的化学和营养成分、枣椰加工业概述以及为增值 DPC 而进行的常见实践，并进行了深入讨论。
