Agar-agar is a type of vegetable gelatin extracted from several genera and species of red seaweed. Agarose is one of the main substances present in agar-agar, being responsible for its gelatinous appearance. The first records of agarose extraction date from the late 1650s or early 1660s. Its discovery is attributed to the Japanese Mino Tarozaemon, having been named after kanten.

The agar-agar gelatin is extracted from the seaweed Gelidum sp. through the boiling process and is widely used in Japanese cuisine.

Benefits of agar-agar

Agar-agar provides many health benefits. About 94% of its fiber is soluble in water and its frequent consumption helps to regulate bowel function. Its high concentration of soluble fiber combined with its low amount of calories provides satiety, helps to regulate the intestine and contributes to weight loss.

  • What is dietary fiber and its benefits?

In addition, agar-agar gelatine does not contain dyes, food additives, animal ingredients and is not tested on animals, making it an option for those who are concerned about health and maintain a vegan philosophy of life.

  • Artificial dyes as food additives: know the divisions, the types used in Brazil and their possible harm
  • Ten dangerous food additives that have already been banned abroad

Despite being a little more expensive than gelatine of animal origin, gelatine from agar-agar has a gelling power ten times greater - and therefore its cost-effectiveness pays off.

Other advantages of agar-agar gelatine are that it does not melt at room temperature and does not change the taste of food, being a real wild card in the kitchen, both for savory and sweet dishes.

Agar is sold as a powder and does not need to be refrigerated to set, nor does it melt at room temperature (like animal gelatine).

Conventional gelatine is made from the boiling of bones, tendons, skin and animal remains that are killed in abattoirs. The most common is that they are the remains of oxen and pigs. As for agar, as it is obtained by boiling seaweed, it provides virtually zero risk of contamination by bacteria that cause serious illnesses.
