Mature okra: a nutrient‐dense crop with untapped applications in health, food and industry

Okra (Abelmoschus esculentus L.) is an economically and nutritionally important crop in tropical and subtropical regions, with global production reaching 11.2 million tonnes annually. Although tender pods are widely consumed, mature okra is often discarded because of its fibrous texture, contributing to a global food waste crisis that carries a true economic impact of USD 2.6 trillion when environmental costs are factored in. With increasing global emphasis on waste reduction and circular resource utilisation, identifying high-value applications for underused agricultural waste is essential. This review addresses the critical gap in waste valorisation by specifically examining the physiological shifts that occur during pod maturation, as well as the industrial applications of okra, particularly its utilisation in bakery products. Evidence indicates that, as okra transitions to the mature stage, its functional components significantly increase, with the mucilage content increasing from 14.74% to 20.99% and cellulose levels increasing from 1.09% to 2.7%. These enhancements facilitate high-value applications in functional foods, biodegradable materials, water purification and renewable energy. The findings highlight mature okra not only as agricultural waste, but also as a superior, cost-effective bioresource. Valorising this underutilised material aligns with circular economy goals and offers strategic economic opportunities for farmers and industries. Further research is warranted to optimise processing and bridge the gap between laboratory validation and industrial implementation. © 2026 Society of Chemical Industry.
