Sugars colors

Color. The visual color, from white to dark brown, of sugar and sugar products is used as a general indication of quaUty and degree of refinement. Standard methods are described for the spectrophotometric deterrnination of sugar color that specify solution concentration, pH, filtration procedure, and wavelength of deterrnination. Color or visual appearance may also be assessed by reflectance measurements. 

Decolorizing Power. — Dissolve 50 gm. of caramel (sugar coloring burnt sugar) in 50 cc. of water, add 100 cc. of 85 per cent alcohol, dilute the whole to 1 liter, allow to stand for several days, and then filter. Dilute 5 cc. of this caramel solution with 50 cc. of water, add 1 gm. of animal charcoal, boil the mixture ten minutes under a reflux condenser, and then filter. The filtrate should be perfectly colorless.

Spectrophotometric and chromatographic studies indicated that the color-bearing compounds responsible for the sugar color development were 5-HMF, caramel, humic acids, and melanoidins. Reduction of these compounds by improving first carbonation technique to minimize reducing sugar destruction would improve color development of the carbonation sugar.

The apparent correlation between optical properties and such processes as clarification, decolorization, and crystallization is deceptive. In each case, complete quantitative evaluation must depend on the actual physical and chemical properties of the sugar colorant, and this information is, for the most part, lacking. 

Purplish-red powder. Imparts fine purplish-red color to alcohol, acid and neutral liquids. The purple tinge may be covered by adding a few drops of burnt-sugar coloring.

Deoxyosones predominantly form pyrazines and imidazoles with ammonia. The following compounds were isolated from sugar coloring (cf. Formula 4.66). 

To improve the technological properties, dry soups and sauces contain a series of other ingredients, e. g., milk products, egg products, sugar, and maltodextrin, acids, soybean protein, sugar coloring, and antioxidants.
