Research of processing optimization of almond oil by subcritical butane using response surface method

Xinjiang apricot cultivars varieties- Red almonds was used as research test material,the response surface method was used in optimizing the extract of almond oil by Subcritical Butane under certain operating conditions.Box- Behnken was designed,SAS8.0 was used in analyzing the effect of extract time,extract temperature,the proportion of dissolved material on almond oil yield.The result showed extract time was 46 min,extract temperature was 42℃,the proportion of materials and solvents was 1 ∶ 6.6g / m L,the extraction rate of almond oil was 88.58%,and its quality indicators are in line with national standards.
