摘要: 为探究氮气脱臭效果,以脱色月见草油为原料,通过使用氮气代替常规的水蒸气进行脱臭,以过氧化值为指标,采用响应面法优化氮气脱臭工艺的最佳脱臭温度、脱臭时间和气体流速。结果表明,最佳工艺条件为脱臭温度144 ℃、脱臭时间3.5 h、气体流速2.1 mL/min,在此条件下月见草油的过氧化值平均值为0.321 mmol/kg,有效降低了月见草油的过氧化值,溶剂残留量为0.02 mg/kg,有效保留了月见草油中的亚麻酸。该方法下得到的月见草油可以通过企业质量指标,为提高月见草油稳定性提供新工艺与理论依据。

Abstract: Nitrogen gas was used to deodorize decolorized evening primrose oil instead of conventional steam distillation. The operating conditions including temperature, time and gas flow rate were optimized by response surface methodology based on peroxide value. The results showed that the optimum process conditions were determined as follows: temperature 144 ℃, time 3.5 h, and gas flow rate 2.1 mL/min. Under these conditions, the peroxidate value of deodorized evening primrose oil was 0.321 mmol/kg, which was effectively reduced compared with that before deodorization. In addition, the solvent residue was 0.02 mg/kg, and linolenic acid was effectively retained in the oil. The quality of the evening primrose oil could meet the industrial requirements. This study provides a new process and theoretical basis for improving the stability of evening primrose oil.

Key words: evening primrose oil, nitrogen deodorization, peroxide value, reduction, effect
