Butter oil often referred to as anhydrous milk fat AMF is a concentrated dairy product made by removing almost all the water and non-fat milk solids from traditional butter. What remains is a golden creamy oil that is rich in milk fat fat-soluble vitamins and natural flavor compounds. With its high stability long shelf life and nutritional density butter oil is widely used in both household cooking and large-scale food industries.
Unlike regular butter which contains about 80% milk fat, butter oil is around 99% pure milk fat making it an energy-dense food. Its lack of water and lactose also means it has a higher smoke point than butter making it more versatile for cooking baking and frying. Additionally butter oil retains the natural richness of butter while being easier to store transport and incorporate into recipes.
History and Origin of Butter Oil
Butter has been a dietary staple for thousands of years with origins traced back to ancient pastoral societies. As people sought to preserve dairy products without refrigeration different techniques were developed to extend butter’s shelf life. One such method was clarifying butter removing water and milk solids to leave behind pure fat.
This process eventually led to the creation of butter oil. In many cultures similar products exist
Ghee in India traditionally simmered butter with the solids removed.
Smorolie in Scandinavia clarified butter used in cooking.
Samna in the Middle East shelf-stable clarified butter.
Modern butter oil production began with advancements in dairy processing in the early 20th century. Today, it is mass-produced using industrial centrifugation and vacuum techniques ensuring consistent purity and quality for both culinary and industrial use.
How Butter Oil Is Made
The production of butter oil involves separating the pure milk fat from other butter components such as water protein and lactose. The steps typically include
Melting Butter Standard butter is gently melted at a controlled temperature.
Separation Water and non-fat milk solids casein lactose are removed through centrifugation or settling.
Purification The milk fat is further purified to remove any residual moisture or proteins.
Vacuum Drying In industrial production vacuum techniques help reduce oxidation and extend shelf life.
Packaging The final product is packaged in airtight containers to preserve freshness.
The result is a highly concentrated stable and flavorful fat with a shelf life of up to 12–18 months when stored properly.
Nutritional Composition of Butter Oil
Butter oil is one of the richest natural sources of pure milk fat. Its nutritional profile makes it calorie-dense but also a valuable source of fat-soluble vitamins and fatty acids.

Health Benefits of Butter Oil

Rich Source of Energy
Butter oil is highly calorie-dense, making it an excellent source of quick energy. Athletes, manual laborers, or individuals requiring high-calorie diets can benefit from its energy-providing properties.
Provides Essential Fat-Soluble Vitamins

Supports Digestive Health
Butter oil contains butyrate, a short-chain fatty acid that nourishes the cells of the colon and supports gut health. Butyrate is linked to reduced inflammation in the digestive tract and improved intestinal function.
Promotes Heart Health in moderation
Although butter oil is high in saturated fats recent studies suggest that natural dairy fats may not be as harmful as once believed. Conjugated Linoleic Acid CLA in butter oil has been shown to have anti-inflammatory properties and may reduce body fat and improve cholesterol balance.
Boosts Immune System
The fat-soluble vitamins in butter oil particularly vitamin A and vitamin D play an essential role in maintaining immune defenses. CLA also contributes to improved immunity and reduced risk of chronic illness.
Improves Bone Health
