Example Embodiment
[0010] The present invention uses pulsed ultrasonic technology to extract the polyphenols in the lotus house. The process steps of the present invention are as follows: Weigh 2.0 g of defatted lotus house powder and place it in a narrow-mouthed beaker, according to the material-to-liquid ratio of 1:10-1: 35 Add a certain amount of 70% acetone, put the narrow-necked beaker in a water bath (with magnetic stirring), then put the ultrasonic probe into the narrow-necked beaker (below 1 cm of the liquid level), and perform ultrasonic assisted extraction. The extraction temperature The temperature is 20~60℃, the ultrasonic time is 10~35min, and the ultrasonic power is 600~1100W.
[0011] The present invention selects extraction temperature, ultrasonic time, ultrasonic power, and material-to-liquid ratio as single factors, and their influence on the extraction rate of polyphenols is shown in figure 1 , figure 2 , image 3 .
[0012] As a preferred solution, the process parameters of t...
