原油品质和精炼过程对油莎豆油综合品质的影响Effects of crude oil quality and refining process on comprehensive quality of Cyperus esculentus oil
为给油莎豆油精炼过程的品质控制提供支持,对2个不同品质的油莎豆原油样品进行水化脱胶、碱炼脱酸、吸附脱色和蒸馏脱臭,对精炼过程中油莎豆油质量指标,脂肪酸、甘油酯组成和营养成分含量进行检测,分析原油品质和精炼过程对油莎豆油综合品质的影响。结果表明:虽然2个不同品质的油莎豆原油的酸价(KOH)有明显差异(分别为2.03、12.21 mg/g),但精炼后酸价(KOH)(分别为0.16、0.33 mg/g)和过氧化值(均为0.01 g/100 g)均显著优于LS/T 3259—2018《油莎豆油》中的指标要求;磷脂含量分别从6 874.10、312.29 mg/kg降至88.61、88.28 mg/kg...
