摘要
以超临界CO2萃取的核桃油为原料,采用均匀试验设计优化其精炼工艺。结果表明:脱酸最适条件为:加碱浓度11.06%,超碱量0.1%,初温45℃,终温80℃;脱色最适条件:活性炭3%,脱色温度85℃,搅拌速度90 r/min,脱色时间50min;脱臭最适条件:温度80℃减压蒸馏脱臭1 h。经过精炼的核桃符合我国粮油行业有关核桃油的标准(GB/T 22327-2008)要求。
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.
