摘要: 花色苷是一类最常见并且分布最广的类黄酮化合物,以糖苷的形式存在于自然界中,是许多植物组织中最主要的水溶性色素,因其具有食用安全、抗氧化能力强、可预防各种慢性疾病等优点而应用广泛。但是由于其结构特点,花色苷的稳定性较差、生物利用率较低,此外,花色苷的强亲水性还限制了其在亲脂性基质中的应用。通过物理与化学等方法进行花色苷改性可以提高其亲脂性能以及在外界环境下的稳定性和抗氧化性,为使其具有脂溶性特征提供一种有效解决策略。本文对各种花色苷的改性方法及改性后产品的性能指标进行了综述和比较,为更深层次地展开对花色苷稳定性、脂溶性、生物活性等方面的研究及其在食品、药品等行业中的应用提供参考。

Abstract: Anthocyanins are one of the most common and widely distributed flavonoids in various plant tissues and naturally occur in the form of glycosides. They are the main water-soluble pigments present in many plants and are widely applied owing to their safety, potent antioxidant properties and biological activities against various chronic diseases. However, due to their structural characteristics, anthocyanins have poor stability and low bioavailability and also possess high hydrophilicity, largely limiting their application in lipophilic matrices. The solubility, stability and antioxidant capacity can be improved through the chemical and physical modification of anthocyanins. This paper reviews and compares the methods used to modify anthocyanins and the properties of the modified products, which will provide references for further studies on the thermostability, lipophilicity and biological activity of anthocyanins and their applications in the food, pharmaceutical and other industries.

Key words: anthocyanin; modification; thermostability; antioxidant capacity; lipophilicity; biological activity; application
