Owing to the increasing worldwide population explosion, managing waste generated from the food sector has become a cross-cutting issue globally, leading to environmental, economic, and social issues. Circular economy-inspired waste valorization approaches have been increasing steadily, generating new business opportunities developing valuable bioproducts using food waste, especially fruit wastes, that may have several applications in energy-food-pharma sectors. Dragon fruit waste is one such waste resource, which is rich in several value-added chemicals and oils, and can be a renewable resource to produce several value-added compounds of potential applications in different industries. Pretreatment and extraction processes in biorefineries are important strategies for recovering value-added biomolecules. There are different methods of valorization, including green extractions and biological conversion approaches. However, microbe-based conversion is one of the advanced technologies for valorizing dragon fruit waste into bioethanol, bioactive products, pharmaceuticals, and other valued products by reusing or recycling them. This state-of-the-art review briefly overviews the dragon fruit waste management strategies and advanced eco-friendly and cost-effective valorization technologies. Furthermore, various applications of different valuable bioactive components obtained from dragon fruit waste have been critically discussed concerning various industrial sectors. Several industrial sectors, such as food, pharmaceuticals, and biofuels, have been critically reviewed in detail.
由于全球人口爆炸式增长，全球范围内管理食品部门产生的废物已成为一个跨领域问题，导致环境、经济和社会问题。受循环经济启发的废物增值方法稳步增加，利用食品废物（特别是水果废物）开发有价值的生物制品，为新的商业机会提供了发展，这些生物制品在能源、食品和制药领域可能有多种应用。火龙果废物就是这样一种废物资源，它富含多种高附加值的化学品和油脂，是一种可再生资源，可以生产出多种潜在应用于不同行业的高附加值化合物。生物炼制厂中的预处理和提取工艺是回收高附加值生物分子的重要策略。有不同的增值方法，包括绿色提取和生物转化方法。然而，基于微生物的转化是将火龙果废物转化为生物乙醇、生物活性产品、药物和其他有价值产品的先进技术之一，通过再利用或回收来实现。本综述简要概述了火龙果废物管理策略和先进的环保且具有成本效益的增值技术。此外，还从不同工业部门的角度，对从火龙果废物中获得的不同有价值的生物活性成分的各种应用进行了批判性讨论。食品、制药和生物燃料等几个工业部门都进行了详细的批判性审查。
