Is Oleostearin Alpha-Gal Friendly?

Caution

Sometimes. Oleo stearine is usually derived from tallow, a rendered form of beef or mutton fat, and may contain alpha-gal when derived from mammals. However, it can be derived from vegetable fats as well, so best to confirm with the manufacturer.

Oleostearin and the Alpha-Gal Friendly Diet

Oleostearin, also known as oleo stearine, is a solid fat often sourced from tallow, which is the rendered fat from beef or mutton. It is primarily composed of stearic and oleic acids. This ingredient is commonly used in food processing for its fat content and can also be found in non-food applications like soap making. It's important for consumers, especially those with specific dietary restrictions like alpha-gal syndrome, to verify the source of oleostearin, as it can also be produced from vegetable fats, which do not contain the alpha-gal epitope.
