Source of Agar agar
Agar agar comes from the cell wall of a species of seaweed (red algae) mostly found in the Pacific and coastal region of California. You can find them in both kitchens and laboratories alike. It’s considered at least 7-8 times stronger than gelatin due to having a plant-based origin.
Source of Gelatin
Gelatin is the non-vegetarian alternative of agar agar. Manufacturers use the acidic and alkaline process to derive gelatin from the collagens of the skins, tendons, and bones of animals. Recently another type of gelatin has earned some popularity which is derived from fish and insects.
Composition of Agar agar
Agar consists of two types of carbohydrates, namely Agarose (70-75%) and Agaropectin (30-25%). It tends to melt at 85 °C (358 K).
The composition of agar agar plays a big role in its property of easy melting and gel stability. It can be ground into a fine powder. So you can commonly find them in the market in the form of powders and strips. It’s white and quite translucent.
Composition of Gelatin
Peptides and proteins are the main constituents of gelatin. They are obtained from the collagen of animal’s bones and other connective tissue through a series of chemical reactions, known as partial electrolysis.
Due to its composition, it melts in any liquid with a temperature of 35° to 40° C. It loses its strength upon exposure to a temperature of more than 100° C (373.15° K).
The gelatin found in the market is much more granular than agar agar. You will mostly find them in packs of powders or sheets. It’s colorless, odorless, and translucent
Uses of Gelatin
Gelatin is used to make various sorts of foods. Common examples are marshmallows, marmalade’s, gummy bears, trifles, frozen desserts, sponge cakes, and other gelatinous desserts. Gelatin is also used to make confections such as jelly toppings for cakes.
Large scaled dairy product factories also use gelatin to prepare products such as margarine, mayonnaise, and yogurt. Technical uses of gelatin include the manufacture of cosmetics, photo films, sandpaper, and capsules of medicines.
Uses of Agar
Since both gelatin and agar agar are gelling agents, therefore most of their uses for culinary purposes are common to each other.
Similar to gelatin, agar agar can be used to make semi-solid desserts such as jellies, custards, puddings, no-bake cheesecakes, etc. Popular Asian desserts such as ‘Wagashi’ (traditional Japanese dessert made from plant-based ingredients) are made with agar agar.
You can use Agar agar to make creamy fillings for sponge cakes or pies or use it as a thickener for gravies of desserts. They are also used in the fields of microbiology, dentistry, etc. Many people use it as a laxative as well.
