This study investigated the impact of various processing methods sun drying, dehydration, frying and cooking) on nutritional and phytochemical profile of wild melon (Cucumis melo var. agrestis). Proximate analysis revealed that drying methods enhanced the concentration of essential nutrients, including carbohydrates, proteins, and fibre, due to moisture reduction. Frying led to an increase in fat content but reduced specific heat-sensitive vitamins and antioxidants. Cooking resulted in varying phytochemical changes, with some compounds degrading while others became more bioavailable. Notably, sun drying and dehydration preserved higher levels of phenolic compounds and flavonoids, enhancing the antioxidant potential of wild melon. These findings highlight the impact of processing on nutrient retention and phytochemical stability, underscoring the need for optimized techniques to maximize its nutritional benefits. Further research is recommended to assess these nutrients' bioavailability and functional health benefits. Practical Application: Through a systematic examination of different processing methods, the research provides novel insights into how these methods influence the melon's nutritional composition and phytochemistry. The findings demonstrate that sun-drying optimizes proximate composition, while thermal drying enhances mineral composition. Additionally, the study highlights the preservation of bioactive compounds in fresh samples and the concentration of organic acids in dried samples. This work advances the field of food science by offering a foundation for optimizing processing methods to enhance traditional foods' nutritional and phytochemical profiles, with significant implications for food fortification, preservation, and security.
本研究调查了多种加工方法(日晒、脱水、油炸和烹饪)对野生甜瓜(黄瓜变种)营养和植物化学成分的影响。近似分析表明,由于水分减少,干燥方法提高了必需营养素的浓度,包括碳水化合物、蛋白质和纤维。油炸导致脂肪含量增加,但降低了特定的热敏维生素和抗氧化剂。烹饪导致了不同的植物化学变化,一些化合物降解,而另一些则变得更具生物利用性。值得注意的是,日晒和脱水保留了较高水平的酚类化合物和黄酮类化合物,增强了野生甜瓜的抗氧化潜力。这些发现突出了加工对营养保留和植物化学稳定性的影响,强调了需要优化技术以最大限度地提高其营养价值。建议进一步研究以评估这些营养素的生物利用度和对健康的功能益处。实际应用:通过对不同加工方法的系统研究,该研究为这些方法如何影响甜瓜的营养成分和植物化学提供了新的见解。研究结果表明,日晒可优化近似成分,而热干燥可提高矿物质成分。此外,该研究强调了新鲜样品中生物活性化合物的保留以及干燥样品中有机酸的浓缩。这项工作通过为优化加工方法以增强传统食品的营养和植物化学特征提供基础,推动了食品科学领域的发展,对食品强化、保存和安全具有重要意义。
