Anthocyanins are flavonoids that are potential antioxidant, anti-inflammatory, anti-obesity, and anti-carcinogenic nutraceutical ingredients. However, low chemical stability and low bioavailability limit the use of anthocyanins in food. Nanoencapsulation using biopolymers is a recent successful strategy for stabilization of anthocyanins. This study reports the development, characterization, and antioxidant activity of black carrot anthocyanin-loaded chitosan nanoparticles (ACNPs).

低分子量壳聚糖纳米封装提高黑胡萝卜花青素的体内抗氧化能力

花青素是类黄酮，是潜在的抗氧化、抗炎、抗肥胖和抗癌的营养成分。然而，低化学稳定性和低生物利用度限制了花青素在食品中的使用。使用生物聚合物进行纳米封装是最近一种稳定花青素的成功策略。本研究报告了黑胡萝卜花青素负载壳聚糖纳米颗粒 (ACNP) 的开发、表征和抗氧化活性。
