| Abstract: | Abstract The process of refining walnut oil extracted by supercritical CO2 was studied using Uniform design method. The results showed that the optimum technological parameter of deacidification were as follows： 11. 06% alkali, 0. 1% ultra - alkali, 45 ℃ the initial neutralization temperature, 80 ℃ the final neutralization temperature. The decoloration process was stirring speed of 90 r/rain for 50 min, with absorbite at 85 ℃. The deodorization by vacuum distillation was at 80 ℃ for lh. After refining, the walnut oil qualified the standards of GB/T 22327 - 2008. |
