摘要
果胶由于其优良的理化性质,在食品、医药、化妆品等众多领域被广泛应用.多酚具有很强的生物活性,但大部分的多酚自身溶解度差,生物利用率低,而将多酚接枝到果胶上可以提高果胶和多酚的利用价值.文章论述了多酚-果胶复合物的合成方法(非共价结合和共价结合)、结构表征(紫外可见光谱、傅里叶红外光谱、核磁共振氢谱、扫描电子显微镜、X射线衍射、差示扫描量热法和热重分析)、生物活性(抗氧化活性、抗菌活性和抗肿瘤活性),阐述了多酚-果胶复合物的应用,并对其应用前景进行了展望.
Abstract
Pectin,known for its excellent physical properties,is widely utilized across various fields,including food,medicine and cosmetics.Polyphenols,although highly bioactivity,often suffer from poor solubility and low bioavailability.Grafting polyphenols onto pectin enhances the functional value of both pectin and polyphenols.The synthesis method of polyphenols-pectin complex(non-covalently bound and covalently bound),structural characterization(ultraviolet-visible spectroscopy,Fourier transform infrared spectroscopy,nuclear magnetic resonance hydrogen spectroscopy,scanning electron microscope,X-ray diffraction,differential scanning calorimetry,and thermogravimetric analysis),biological activity(antioxidant activity,antibacterial activity,and antitumor activity).Lastly,the diverse applications of polyphenol-pectin complexes in multiple fields and their potential for future development are explored.
