Abstract


Golden Flower Tea has the scientific name Camellia chrysantha. It can effectively enhance human immune function, prevent and fight cancer, be anti-aging and prolongs life, and be a powerful antioxidant. Polymer systems loading Golden Flower Tea extract can enhance their solubility and effectivity in simulated body solutions such as stomach or intestine environments. In this paper, chitosan and alginate, two natural polymers, were selected for the preparation of chitosan/alginate loading Golden Flower Tea extract thanks to their many advantages. The method was used in preparation of chitosan/alginate film loading Golden Flower Tea extract is solution method with appreciated solutions for each substance. The suitable ratio of alginate/chitosan obtained from previous studies is 7/3. The characteristics of these films are evaluated by Fourier Transform Infrared (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM), and Differential Scanning Calorimetric (DSC) methods. The obtained results show that polyphenols interact and disperse regularly in polymer matrix.
