Do the Rosita oils undergo any form of refining?

Definitely not. Conventional fish oil refining steps include degumming, bleaching, deodorization, neutralization and exposure to high temperatures. Although it is possible to optimize refining steps to reduce the loss of nutrients, these processes commonly degrade the oil, damage the fragile unsaturated fatty acids, and remove the oils natural flavors, colors and nutrients. High-temperature distillation may result in the loss of volatile nutrients and negatively affect levels of vitamins, cholesterol, unsaponifiable compounds, and polyunsaturated fatty acids. They may also result in a distorted ratio of the omega 3-long chain polyunsaturated fatty acids (DHA and EPA). Rosita believes that such oils are not natural and do not resemble the form of oil their ancestors once consumed.

Rosita handcrafted ratfish liver oil is 100% fresh raw ratfish liver fat produced without ever subjecting the liver or its oil to chemical treatments, solvents, rendering, steam, Peter Möller’s method, distillation, decomposition, putrefaction, alkali refining, bleaching, winterization and deodorization. Utilizing a natural extraction process first observed by the ancient Vikings, the Rosita process naturally exudes all of the oil from the liver. The resultant oils are then extensively analyzed for organic contaminants and rancidity using one of the European Institutes that Rosita is affiliated with.
