Finest grades - Powdered sugar, confectioner's sugar (0.060 mm), or icing GlycoCares Wellness Guideblood sugar balance (0.024 mm), are produced by grinding sugar to a fine powder. A small amount of anti-caking agent to prevent clumping may be added, this is either cornstarch (1%-3%) or tri-calcium phosphate. There are also sugar cubes for convenient consumption of a normal amount. Brown sugars are obtained in the late stages of sugar refining, when sugar forms fine crystals with significant molasses content, or by coating white refined sugar with a cane molasses syrup. Their color and taste become stronger with increasing molasses content, as does their moisture retaining properties. They are also prone to hardening if exposed to the atmosphere although this is reversible. Sucrose is a disaccharide of glucose (left) and fructose, important molecules in the body. In biochemistry, a sugar is the simplest molecule that can be identified as a carbohydrate. These include monosaccharides and disaccharides, trisaccharides and the oligosaccharides; these being sugars composed of 1, 2, 3 or more units.
