ABSTRACT
AIM:
In order to improve the clarity and quality of Ginkgo leaf water-extraction solution,and optimize the production process.METHODS:
The experiment was based on the optical absoiption and scattering rate,flocculation rate and loss in flavanones were used as two main parameters to estimate the effect of influencing factors on flocculation.It could be proved by analyzing the particle size in water-extraction solution before and after flocculation.RESULTS:
The best flocculation technological parameters of water-extraction solution of Ginkgo leaf with chitosan were as followsat flocculant concentration of 1.071 g/L,flocculation temperature of 40(?C),pH of 4.9.CONCLUSION:
The flocculation of water-extraction solution of Ginkgo leaf with chitosan is effective and selective,it has the advantage over ethanol precipitation method.
