潲水油在精炼中卫生指标的检测与分析

Hygiene indexes detection and analysis of hogwash oil in refining process

依据食用油脂精炼工艺,对毛潲水油进行不同程度精炼处理,并对不同精炼阶段的样品进行卫生指标检测。结果表明,经脱胶、脱酸、脱色、脱臭后的样品黄曲霉毒素B1及苯并(a)芘高达21μg/kg和11μg/kg,分别超出国家规定食用植物油卫生标准的5%和10%,且其电导率及极性成分也远高出市售食用植物油。因此,毛潲水油及其各精炼阶段的样品均属不可食用油脂。

The crude hogwash oil was refined and the hygiene indexes of samples at different steps of refining were detected. The results showed that the aflatoxin B1 （AFB1） and benzo（a） pyrene contents of the sample after degnmming, deaeidification, bleaching and deodorization were 21 μg/kg and 11μg/kg, which respectively exceed 5% and 10% of the corresponding indexes in the national hygienic standard for edible vegetable oil. In addition, the conductivity and polar components contents of the sample were higher than that of commercial edible vegetable oil. The crude hogwash oil and the samples at different steps of refining were in edible.
