Post-harvest handling and storage techniques for maintaining nutritional quality in sweet potato (Ipomoea batatas)

Sweet potato (Ipomoea batatas) is an essential root crop with high nutritional value, including significant amounts of vitamins, minerals, dietary fiber, and antioxidants. However, its post-harvest handling and storage conditions significantly impact its nutritional quality, shelf life, and market value. This paper explores the effects of various post-harvest handling and storage techniques on the retention of nutritional qualities such as antioxidant activity, vitamins (particularly beta-carotene), and minerals. Through a review of current literature and experimental data, we discuss methods like curing, temperature and humidity control, and packaging that help preserve the nutritional integrity of sweet potatoes after harvest. The study provides recommendations for optimal handling and storage practices that can enhance the marketability and health benefits of sweet potato in agricultural systems.
