In European countries, this thickener appeared only in the XIX century, and even then it was used, mainly by biologists, as a breeding ground for the reproduction of bacteria. And popularity as a food product, he acquired relatively recently.

Composition and useful properties

Agar-agar is a product of plant origin with a complex composition. It includes:

  • Polysaccharides (agaropectin, agarose and others), which give it the properties of jelly;
  • Pyruvic and glucuronic acids;
  • Mineral substances, including calcium and iodine;
  • Iron;
  • A variety of vitamins.

If you compare agar-agar with gelatin, you can find many advantages of this thickener:

  2. It is more economical than gelatin, in water its volume increases in 30 times;
  3. This substance without taste and smell, which is important for cooking;
  4. Agar-agar is almost transparent, whereas gelatin is unclear;
  5. Jelly, cooked using a thickener from algae, can be heated to a boil, and then cooled, and it will again take a jelly-like shape. But gelatin does not have this property;
  6. Zero calorie content can also be considered an advantage in a number of cases;
