The invention provides a composition rich in flavonoids based on natural extracts, comprising a flavonoid extract dispersed by melt mixing or extrusion and encapsulated in a polymer matrix. The invention is also a novel dietary supplement with the naturally occurring ingredient (−)-epicatechin, cacao extracted, that could potentially prevent or reduce the risk of Atherosclerotic pathology. The use of (−)-epicatechin is promising as a therapeutic agent due to its potential antioxidant activity and its diverse biological properties. (−)-Epicatechins are chemically unstable and extensively degraded in fluids of near neutral or greater pH, such as intestinal juice and bile. Current technologies used for taste masking and modified release as spray drying, liposome entrapment, co-crystallization, freeze drying, among others, suffer from numerous shortcomings, including poor repeatability and limitations on target delivery.
本发明提供了一种基于天然提取物的富含类黄酮的组合物,该组合物由通过熔融混合或挤压分散的类黄酮提取物组成,并封装在聚合物基质中。本发明也是一种新型膳食补充剂,含有天然成分(-)-表儿茶素(可可提取物),有可能预防或降低动脉粥样硬化病变的风险。由于(-)-表儿茶素具有潜在的抗氧化活性和多种生物特性,因此很有希望用作治疗剂。(-)-表儿茶素化学性质不稳定,在pH值接近中性或更高的液体(如肠液和胆汁)中广泛降解。目前用于掩味和改性释放的技术包括喷雾干燥、脂质体包埋、共结晶、冷冻干燥等,这些技术存在许多缺点,包括可重复性差和靶向递送受限。
