Abstract

Millets, also known as Nutri-cereals, are a traditional food source in many countries. They are comprised of essential nutritional elements, including carbohydrates, proteins, dietary fiber, lipids, vitamins, minerals, and various phytochemical compounds required for healthy longevity. Because of their low glycemic index and gluten-free status, millets suit various dietary requirements. This comprehensive review explores different techniques used for isolating health-promoting components from millets. Conventionally, most of the Nutri-components from millets can be isolated by using solvent extraction. However, it is associated with limitations such as low efficiency and potential degradation of bioactive compounds. The application of innovative extraction methods like ultrasonication-assisted, microwave-assisted, enzymatic-assisted, pulse electric field-assisted, and supercritical fluid techniques play crucial roles in enhancing extraction yield and improving functional attributes. The selection of proper extraction methods varies due to several factors, including the targeted components, the properties of the millet matrix, extraction efficacy, extraction speed, and economic considerations. Additionally, the review underscores the potential of millet bioactive component applications in functional foods, nutraceuticals, and other industrial products. The extraction and utilization of millet nutritional components provide a valuable outline for advancing scientific research and industrial innovation, addressing the global demand for sustainable and health-focused solutions.

Graphical Abstract

小米营养成分的先进提取技术及其功能应用综述
小米,也被称为营养谷物,是许多国家的传统食物来源。它们由必需的营养元素组成,包括碳水化合物、蛋白质、膳食纤维、脂质、维生素、矿物质和健康长寿所需的各种植物化合物。由于其低血糖指数和无麸质状态,小米适合各种饮食需求。这篇综合综述探讨了从小米中分离健康促进成分的不同技术。通常,大多数的营养成分从小米可以分离出来,用溶剂萃取。然而,它与诸如低效率和潜在的生物活性化合物降解等局限性有关。超声辅助、微波辅助、酶辅助、脉冲电场辅助、超临界流体技术等创新提取方法的应用,对提高提取率、改善功能属性具有重要意义。选择合适的提取方法取决于几个因素,包括目标成分、谷子基质的性质、提取效果、提取速度和经济考虑。此外,该综述强调了小米生物活性成分在功能性食品、营养保健品和其他工业产品中的应用潜力。小米营养成分的提取和利用为推进科学研究和产业创新提供了有价值的轮廓,满足了全球对可持续和健康解决方案的需求。图形抽象
