Peanuts contain a diverse and vast array of chemical and biological compounds having a rich nutritional profile and contain an excellent source of health-promoting substances. This multipurpose product can be used to extract oil and protein which plays an important role in the economy of many countries. Therefore, covering all aspects of peanut structural components (including peanut bioactive compounds, proteins, and oil content) and studying different approaches from oxidation mechanisms to improving the quality shelf life of peanuts (by introducing coating agents or the impact of storage conditions and packaging materials) seem to be necessary. Also, the present review will summarize the extraction methods and advance technologies for obtaining peanut protein/oil to reduce the use of classical methods and energy-intensive technologies for peanut processing (from harvest to storage). Therefore, increasing information in these issues will help the general peanut processes perform with a shorter time and less consumption of chemicals (such as organic solvents for oil extraction or chemical antioxidants to increase shelf life). Finally, this paper provides a summary and outlook of the peanut wastes as an applicable agricultural by-products. In this regard, this review will also aim at identifying areas where knowledge is insufficient and setting priorities for further research.

花生含有多种化学和生物化合物，具有丰富的营养成分，并且是促进健康的物质的极好来源。这种多用途产品可用于提取油和蛋白质，在许多国家的经济中发挥着重要作用。因此，涵盖花生结构成分（包括花生生物活性化合物、蛋白质和油脂含量）的各个方面，并研究从氧化机制到提高花生质量货架期的不同方法（通过引入涂层剂或储存条件和包装材料的影响） ）看来是有必要的。此外，本综述将总结获得花生蛋白/油的提取方法和先进技术，以减少花生加工（从收获到储存）的经典方法和能源密集型技术的使用。因此，增加这些问题的信息将有助于缩短一般花生加工的时间并减少化学品的消耗（例如用于提取油的有机溶剂或用于延长保质期的化学抗氧化剂）。最后，对花生废弃物作为农副产品的应用进行了总结和展望。在这方面，本次审查还将旨在确定知识不足的领域并确定进一步研究的优先事项。
