Agar is part of daily life and is not only linked to food. There is a long list of diseases in which agar and peptones play a key role in their diagnosis: respiratory, digestive system and urinary diseases, and many more. Some of them are easily treatable and others are of concern to the WHO because of their resistance to antibiotics.

Hispanagar has a wide variety of agaroses for different applications. In this post, we will review the most common uses of this versatile product. 

Hysteresis is the difference between the gelling and melting temperatures of a gel.

Agar has the highest hysteresis of all hydrocolloids. Once dissolved at 1-1.5% concentration in water, the solution forms a gel upon cooling to 34-38 ° C, and that gel only melts if heated to 85-90 ° C, not before.
