Background

After the fish oil is degummed, deacidified and the like, a small amount of solid fat is flocculent and precipitated in the storage process, so that the appearance is influenced. The national standards of edible oil require a freezing test, namely: standing the grease for 5.5h at the low temperature of 0 ℃, and observing whether the grease contains fat crystals or floccules, wherein qualified samples are required to be clear and transparent. In order to meet the requirements of national standards, fish oil is often winterized in the production process so as to crystallize and separate out oil ester with higher freezing point and the like.
