Embodiment Construction
[0020] The present invention will be further described below through specific examples.
[0021] 1. Hydrochloric Acid Degradation of Alkali Extracted Polysaccharide from Passion Fruit Peel
[0022] (1) Effect of hydrochloric acid concentration on polysaccharide degradation:
[0023] Alkali-extracted polysaccharides were prepared into a 5 mg / mL solution, and the reaction time was 60 minutes, and the reaction temperature was 60 °C. The effect of degradation. After the reaction was finished, it was adjusted to neutrality, dialyzed in running water for 48 hours, and freeze-dried after concentration ( figure 1 ).
[0024] (2) Effect of reaction temperature on polysaccharide degradation:
[0025] Alkali-extracted polysaccharides were formulated into a 5 mg / mL solution, and the reaction time was 60 minutes, and the concentration of hydrochloric acid was 0.3mol / L. The effect of degradation. After the reaction was finished, it was adjusted to neutrality, dialyzed in running water...
