Example Embodiment
[0041] Example 1
[0042] A beverage made by blending tea tree flowers, Tibetan tea, black tea, and green tea, including the following raw materials by weight:
[0043] 20 parts of tea tree flower, Tibetan tea, black tea, and green tea blended tea, 10 parts of white sugar, 0.015 parts of modified chitosan nanoparticles, 0.015 parts of sodium ascorbate, and 500 parts of water.
[0044] The method for preparing modified chitosan nanoparticles includes the following steps;
[0045] Weigh 1g of chitosan and add it to 100mL of 1% acetic acid solution with a mass fraction of 1%. Stir thoroughly to dissolve it to prepare a chitosan-acetic acid solution. Adjust the pH of the solution to 5 with 0.01mol / L NaOH, and add 3g of sodium tripolyphosphate. After stirring the reaction for 30 minutes, pour the solution into a centrifuge tube and place it in a refrigerated centrifuge for 30 minutes at a speed of 9000 r / min. Separate the supernatant from the sediment, and wash the lower sediment with deio...
