Thickener

Agar, also known as agar-agar, is a plant-based gelatin derived from red algae, commonly used as a thickener in food products.

What is Agar?

Agar is a vegetarian gelatin substitute derived from red algae, particularly from the genera Gelidium and Gracilaria. It is known for its gelling properties, making it a popular ingredient in desserts, jellies, and other food products that require a firm texture. Unlike animal-based gelatins, agar is suitable for vegans and vegetarians, as it is entirely plant-based.

Why People Avoid Agar

People may avoid agar if they have sensitivity to alpha-gal, a carbohydrate found in red meat and certain other products derived from mammals. Although agar is plant-based, the note suggests it contains alpha-gal, possibly due to contamination or processing practices. Additionally, individuals who have allergies or sensitivities to seaweed or algae may also avoid agar.
