What is gelatin made of?
Typical gelatin is a protein obtained by boiling skin, tendons, ligaments, or bones with water. Most of the used materials are obtained from cows and pigs. Therefore, gelatin is not vegan.

Where is gelatin used?
Gelatin is still widely used by the food and cosmetics industry. Typical use cases are:
Gelatin use in cosmetics
Used in shampoos, face masks, and other cosmetics.

Gelatin use in beverages
Sometimes gelatin is also used to assist in clearing wine and beer.
Agar-agar, the vegan gelatin alternative
Agar-agar is a plant-based gelatin derived from seaweed. It’s widely sold in flake, powder, bar, and strand form. It’s often used in dairy-free and vegan recipes as a stabilizing and thickener. It also is used in gluten-free recipes as a thickener and is very nutritious.

Difference between agar-agar and gelatin
The main difference between agar-agar and gelatin is from where they are derived. Whereas animal-based gelatins are made from animals, agar-agar is vegan, coming from the red algae plant. Also, when cooking with agar-agar, it needs different preparation. For example, agar-agar needs to boil to set, while gelatin can simply dissolve in warm water.
