Description

Agar is not a chemically defined product. It is a natural blend of polysaccaharides made up by Agarose, a neutral molecule and other more coomplex molecules known as Agaropectines.

Agar is insoluble in cold water. 1,5% Agar solution in boiling water forms a gel when cooling down an this will not melt until heated over 85oC. Agar does not need the presence of cations in order to gellify an it shows a higher gel consistency than any other gellifying agent.

Agar can be used within ample range of pH reading (5-8). Agar can be utilized blended with other gums, and it is a calorie-free fibre as it is not digestible by man.
