Other culinary gelling agents can be used instead of animal-derived gelatin. These plant-derived substances are more similar to pectin and other gelling plant carbohydrates than to gelatin proteins; their physical properties are slightly different, creating different constraints for the preparation and storage conditions. These other gelling agents may also be preferred for certain traditional cuisines or dietary restrictions.
Agar, a product made from red algae,[4] is the traditional gelling agent in many Asian desserts. Agar is a popular gelatin substitute in quick jelly powder mix and prepared dessert gels that can be stored at room temperature. Compared to gelatin, agar preparations require a higher dissolving temperature, but the resulting gels congeal more quickly and remain solid at higher temperatures, 104 °F (40 °C),[5] as opposed to 59 °F (15 °C)[6] for gelatin. Vegans and vegetarians can use agar to replace animal-derived gelatin.
Carrageenan is also derived from seaweed, and lacks agar's occasionally unpleasant smell during cooking. It sets more firmly than agar and is often used in kosher and halal cooking.
Konjac is a gelling agent used in many Asian foods, including the popular konnyaku fruit jelly candies.
