| Abstract: | Walnut kernels' skin contains a substance called polyphenol which has an oxidation resistance property.This research discusses how concentration of ethanol,ratio of liquid to material,extracting time and temperature affect the result for extracting polyphenols from walnut kernel's skin.We optimized the condition through an orthogonal test.The optimum technology requirements are as follows:concentration of ethanol 60%,ratio of liquid to material 1 to 8,extracting time 30 min,and the extracting temperature 55 ℃.The extraction rate is 5.71 mg·g-1. |
