Banana is one of the most consumed and popular fruits in all regions of the world, being cultivated mainly in tropical countries. It is not only a rich source of vitamins A, C, and B, calcium, iron, potassium, phosphorus, and other vitamins and nutrients, but it also contains several types of antioxidants with high nutritional value. In this context, the current study aimed to quantify the content of ascorbic acid, flavonoids, pigments, and minerals present in "Nanicão" bananas during the ripening process. As demonstrated, the level of flavonoids was higher in ripe and overripe fruits, whereas the mineral composition was high only at ripening stage 4 (more yellow than green) a stage that should be prioritized when recommending fruit consumption to the population deficient in these minerals. Regarding pigments, there was a reduction in chlorophylls a and b and an increase in carotenoids and anthocyanins in peels and pulps. PRACTICAL APPLICATION: Flavonoids are phenolic, bioactive compounds with proven antioxidant and anti-inflammatory activity and products of the plant's secondary metabolism. The degradation of chlorophylls and synthesis of carotenoids and anthocyanins, and as a consequence of the latter pigment, the increase in flavonoids in the pulp was evident during the monitoring of ripening, mainly in the fruit peels in relation to pigments. Minerals are essential elements, the main ones provided in balanced diets and important for dietary and nutritional health.
香蕉是世界各地区广泛食用和流行的水果之一,主要在热带国家种植。它不仅是维生素 A、C 和 B、钙、铁、钾、磷和其他维生素和营养物质的丰富来源,还含有几种具有高营养价值的抗氧化剂。在这种情况下,目前的研究旨在量化“Nanicão”香蕉在成熟过程中抗坏血酸、类黄酮、色素和矿物质的含量。研究表明,成熟和过熟果实中的类黄酮含量较高,而仅在成熟阶段 4(比绿色更黄)时矿物质含量较高,这一阶段应优先考虑向矿物质缺乏的人群推荐水果消费。关于色素,果皮和果肉中的叶绿素 a 和 b 减少,类胡萝卜素和花青素增加。实际应用:类黄酮是酚类、生物活性化合物,具有已证明的抗氧化和抗炎活性,是植物次生代谢的产物。在成熟监测过程中,叶绿素降解、类胡萝卜素和花青素合成,以及由于后一种色素的增加,果肉中的类黄酮明显增加,主要是在果皮中与色素有关。矿物质是必需元素,主要存在于均衡饮食中,对饮食和营养健康很重要。
