以苦杏仁为原料，本试验选用正己烷为溶剂提取杏仁油，并进行了脱色处理和稳定性试验。结果表明：苦杏仁中脂肪含量49.58%；单因素试验证明：正己烷提取杏仁油的最佳参数为：浸提温度65 ℃，浸提时间5 h，料液比为1:10时，提取率达92.0%；脱色剂（活性白土）的最佳参数为：用量10%，处理条件：温度70 ℃，脱色时间55 min。稳定性试验表明：0.01% PG作为抗氧化剂增强杏仁油稳定性效果明显。

Bitter almond oil was extracted by n-hexane and the decolorization of the achieved oil was investigated. The results showed that the fat content in bitter almond was 49.58%. The optimum extraction parameters with n-hexane were temperature 65 ℃, time 5h and solid/ liquid ratio 1:10, under which the oil yield reached 92.0%. The optimum decolerization parameters with active white soil as decolorizer were: decolorizer dosage 10%, temperature 70℃and time 55min. The stability of the bitter almond oil showed that 0.01% PG as antioxidant significantly enhanced the oil stability.
