摘要
茶多酚有抗氧化、抗菌、抗癌、抗辐射、提高机体免疫力等作用,但因其脂溶性较弱、稳定性差,容易被氧化,并且在碱性溶液中活性大大降低,故在实际应用中常常受到限制。纳米级茶多酚微粒较普通微粒在粒径、脂溶性、稳定性、抗氧化性、透皮性等方面等有更大的优势,因此其在食品、医药、日化工业中有广泛的应用前景。本文对茶多酚纳米级微粒的制备技术及应用进行综述,并对其发展前景做出展望。
Tea polyphenols have multiple health benefits including antioxidant and antibacterial activities,cancer prevention,anti-radiation and immune enhancement.However,the application of tea polyphenols is often limited due to weak fat-soluble property,poor stability to oxidation,and reduced activity in alkaline solution.Tea polyphenol nanoparticles have greater advantages in size,fat solubility,stability,oxidation resistance,transdermal activity and other aspects than the ordinary tea polyphenol samples.Currently,tea polyphenol nanoparticles have been widely applied in the food,medicine and daily chemical industries.In this paper,the current preparation technologies and applications of tea polyphenol nanoparticales are reviewed and the future development trend is also proposed.
