Abstract

Abstract:

Chitosan has many health functions such as decreasing blood cholesterol, lowering blood pressure, anti-infections, controlling arthritis, anti-cancer and so on. However, the water solubility of normal chitosan is very poor, which is usually dissolved with acid solution. Recently researchers found that synthesized chitosan derivatives not only can increase the water solubility of chitosan but also improve the antibacterial activity of chitosan, making it possible to use chitosan as a natural food preservative .

Key words: chitosan, chitosan derivative, water solubility, antibacterial activity, antibacterial mechanism
