Caramel Color - Production

Production

Caramel is manufactured by heating carbohydrates, either alone or in the presence of acids, alkalies, and/or salts. Caramel is produced from commercially available nutritive sweeteners consisting of fructose, dextrose (glucose), invert sugar, sucrose, malt syrup, molasses, starch hydrolysates and fractions thereof. The acids that may be used are sulfuric, sulfurous, phosphoric, acetic, and citric acids; the alkalies are ammonium, sodium, potassium, and calcium hydroxides; and the salts are ammonium, sodium, and potassium carbonate, bicarbonate, phosphate (including mono- and dibasic), sulfate, and bisulfite. Antifoaming agents, such as polyglycerol esters of fatty acids, may be used as processing aids during manufacture. Its color ranges from pale-yellow to amber to dark-brown.

Caramel color molecules carry either a positive or a negative charge depending upon the reactants used in their manufacture. Problems such as precipitation, flocculation, or migration can be eliminated with the use of a properly charged caramel color for the intended application.

Famous quotes containing the word production:

    The production of too many useful things results in too many useless people.
    Karl Marx (1818–1883)

    The problem of culture is seldom grasped correctly. The goal of a culture is not the greatest possible happiness of a people, nor is it the unhindered development of all their talents; instead, culture shows itself in the correct proportion of these developments. Its aim points beyond earthly happiness: the production of great works is the aim of culture.
    Friedrich Nietzsche (1844–1900)

    ... this dream that men shall cease to waste strength in competition and shall come to pool their powers of production is coming to pass all over the earth.
    Jane Addams (1860–1935)
