100% Pure, Grade A, AEA Certified Montana Emu Ranch oil is single batched, meaning all fat used to produce our oil is from birds grown on our ranch.(Many other facilities blend oils from various ranches). The refining process eliminates impurities such as, free fatty acids and peroxide levels. Each batch of oil is tested by an independent lab and measured for various fatty acid content, color, odor, and stability. Our emu fat is consistently rated within the top 2% of fat produced in the nation based on cleanliness, color, and yield. Our Emu oil is very stable, odor free and highly active.
