What is agar-agar: composition, properties, application
In order to prepare a jellied, jelly or marmalade, traditional European cooking uses gelatin – a thickener of animal origin.
But in the countries of Asia for this purpose agar-agar is used most often – a unique product, the spheres of use of which are very diverse.
Agar-agar – what is it?
It is a thickener of food in the form of powder or shavings of white, and sometimes yellowish color. Dissolved in hot water, after hardening, it acquires a consistency of jelly or thick gel.
Born into the sea
Unusual for our hearing name comes from the Malay language, where "agar" translates as "algae". Indeed, the well-known agar agar in South-East Asia is made from certain species of algae red and brown, which are extracted from the seabed or artificially grown on special plantations.
These heat-loving algae grow in the warm seas of the tropics and subtropics, and many of their species are of nutritional value and have long been used for food, for example, nori, hijiqi, arame.
The properties of the broth of these algae, the inhabitants of the coastal areas of Southeast Asia have known for a long time and used the resulting jelly not only as food, but also as a therapeutic agent.
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;
- A variety of vitamins.
Microelements and vitamins that are part of agar-agar are not only useful, but also necessary for the body. This thickener is an important food additive, its labeling is E 406.
If you compare agar-agar with gelatin, you can find many advantages of this thickener:
- Jelly, cooked on agar-agar, retains its properties longer than gelatin-made, since the agar remains in the form of a dense gel and at a temperature of 40 degrees;
- It is more economical than gelatin, in water its volume increases in 30 times;
- This substance without taste and smell, which is important for cooking;
- Agar-agar is almost transparent, whereas gelatin is unclear;
- 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;
- Zero calorie content can also be considered an advantage in a number of cases;
- Being of plant origin, agar-agar is suitable for cooking lean food.

If we talk about the shelf life, then agar-agar is a perishable product. Jelly with it is better to use not later than a day from the moment of preparation.
The shelf life of the powder is indicated on the package, but usually a hermetically sealed packet with a thickener should not be stored for longer than a year, because the substance loses its gelling properties.
