Agar Agar

Agar Agar Industry @ a Glance

The natural gelling agent Agar-Agar 
is extracted from the Gelidium and Gracilaria seaweeds (bot. fam. Rhodophyceae). Gelidium is mostly found on the Atlantic coast of Southern Morocco, Spain, Portugal and France while Gracilaria grows on the coastline of Chile, South Korea, Japan and Argentina.

Agar-Agar is soluble in hot water. Agar solutions
are viscous and fluid and they jellify at room temperature, creating thermoreversible
gels that melt again at 85±5 °C and reform
a gel on cooling down to 35±5 °C. This unique hysteresis offers many advantages in food production

Agar Agar applications are in Confectionery, Bakery, Dairy products, Pastry, Sauces & Dressings, Meat Products, Spreads, Beverages

Modern day production of agar involves an
extraction of the seaweed liquor under high pressure. The gel is then pressed to eliminate free water and once in cake form is dried in large drying ovens.

Agar is widely used in scientific, industrial, and medical
laboratories around the world as a “culture medium” for growing microorganisms, such as bacteria, to test for infections
