What is Agar-Agar Powder

Agar-agar powder is hugely known as a plant-based white and semi-translucent substance containing a mix of carbohydrates extracted from seaweed, mostly red algae. It can be found in markets in powder, bar, strand, and flake forms as well. The uses of agar-agar powder range from the food industry to certain scientific applications. Some of its uses are filler in sizing paper, clarifying agents in brewing, and also for cooking. It is also known as China grass, China glass, Japanese kanten, and many more.

While the jelly-like texture of Agar-Agar powder is very similar to that of gelatin, both substances are quite different. The first disparity between agar-Agar and gelatin is the source of the material. Agar-agar is entirely vegetarian since it comes from red algae, whereas gelatin is made from collagen which is a type of protein that can be found in the skin, joints, and hair of livestock. Second, the discrepancy is the method of preparation of the substances. Agar-agar needs to be boiled in order to bring the jelly-like texture. Meanwhile, gelatin can simply be dissolved in warm water. The last difference is that agar-agar needs refrigeration to set the texture while gelatin does not.

After that, agar goes through the boiling process to be dissolved. The rest of the steps are filtration, gelling, freezing, drying, milling, and packing.
