Response Surface Method was Used to Optimize the Extraction Process of Tea Polyphenols From Pu'er Green Tea
The use of ultrasonic assisted ethanol extraction method to extract tea polyphenols from Pu'er raw tea is a highly scientific and practical research.The extraction factors that affect the content of tea polyphenols in tea include material liquid ratio,ethanol concentration,frequency,temperature,and time.In order to maximize the extraction effect of tea polyphenol content,we used single factor experiments,PB experimental design,and response surface methodology to determine the optimal extraction conditions to ensure the scientific and reliableresearch results[1].The best extraction conditions obtained in this experiment were:material to liquid ratio 1:30,ethanol concentration 40%,extraction times 5 times,extraction temperature 78℃,extraction time 25 minutes.When extracted using these extraction conditions,the content of tea polyphenols in tea was 41.93%,providing a reference basis for its extraction and development in the industrial,food,and medical fields.
