你想说的黑心油是不是就是现在所说的地沟油啊？？如果是一样的意思，可以用
hogwash
oil.
看以下例句：
1.
A
gas
chromatographic
method
for
determination
of
cholesterol
was
applied
to
distinguish
hogwash
oil
from
the
edible
vegetable
oil.
动物脂肪中普遍含有大量的胆固醇，而在植物油中一般不含或含有极少量的胆固醇。
2.
The
results
showed
that
when
hogwash
oil
into
edible
oil
upwards
of
10%,
the
characteristic
peak
of
cholesterol
could
be
observed
obviously.
利用极性毛细管色谱柱可将油脂中的胆固醇和植物甾醇很好地分离，从而可鉴别油样中是否混有地沟油。
