Starch consists of molecular chains of glucose which can be straight (amylose) or branched (amylopectin). When the weather is favorable, the plants produce more energy than they consume; the excess is then stored in the form of starch. Starch can be broken down into glucose units again with the help of the enzyme amylase. The intermediate in that reaction is maltose. The glucose residues are (as in maltose) bound with so-called α-binding, in contrast to cellulose (and cellobiosis) which have β-binding. This makes the polymer chains in cellulose elongated, while the starch chains become more flexible and like a ball. Humans cannot break down cellulose, as amylase only breaks down α-bonds. On the other hand, the grazing apparatus of grazing animals is designed so that the cellulose found in grass and hay, etc. can be broken down. Starch can be detected with iodine. Starch gives dark blue color with iodine. A starch molecule is made up of hundreds of sugar molecules. The starch grains are stored as a reserve nutrient for rest, germination or growing periods in the plants' seeds, tubers, roots or stems. The microscope reveals that the starch is made up of small, white grains with a size between 1 and 100 microns in diameter. Each starch type has its characteristic size and shape of the grains. The purpose of modifying starch is to change one or more of the following properties: pre-gluing temperature the viscosity / concentration ratio swelling and boiling properties retrogradation tendency stability in solution to degradation by the action of acid, heat and / or mechanical shear young character hydrophilicity Chemical and / or physical modification changes the properties of native starch.
