采用碱溶酸沉法提取桃仁蛋白，并采用正交试验确定最佳提取工艺，试验对桃仁蛋白的溶解性和吸油性进行测定。结果表明，桃仁蛋白的最佳提取工艺为pH值10，料液比1∶30，提取温度40℃，提取时间75 min，桃仁蛋白的最佳提取率为24.06%。测定溶解性表明，温度为50℃时桃仁蛋白溶解度最大；测定吸油性表明，静置时间为50 min时，吸油性最大。

In this paper,through alkaline extraction and acid precipitation,the protein from peach kernel is extracted to determine the optimum process conditions of extracting peach kernel protein by single factor and orthogonal experiments. And the solubility and oil absorption capacity are also measured. The optimal extraction conditions are:pH 10,the ratio of meal to solvent 1∶30,temperature 40 ℃and 75 min. Under these conditions,the extraction yield is 24.06%. Determination of solubility shows that when the temperature is 50 ℃,peach protein solubility is maximum;determination of oil absorption capacity show that:when holding time is 50 min,oil absorption is maximum.
