Steric hindrance as a result of the introduced phosphate groups inhibits the linearity of amylose or the outer branch of the amylopectin chain where it reacted. We supply different grades of maize starch: regular maize starch, low moisture maize starch and white maize starch. But also in the construction industry for concrete admixtures, plasters and insulation, as well as in oil drilling, mineral and metal processing. Phosphorylation has been demonstrated to mostly occur at the C-3 and C-6 of the glucose units, and the degree of phosphorylation depends on distribution of the chain length of the starch polymers [30]. Contrariwise, the paper sheets will not be smooth and flat. It is the starting product form which liquid glucose, dextrose, dextrin are made. The phosphate bridge or cross-linking strengthens the mechanical structure of the starch granules. This reaction process produces hydroxypropylated starch (HPS), which is a starch ether produce by reaction of starch with propylene epoxide in the presence of an alkaline catalyst (Figure 14). Such modified starch shows profound change in functionality such as solubility, gelatinization, pasting and retrogradation [11]. Inorganic esters also exist, for instance, esters of phosphorous acid (H3PO3) and phosphoric acid (H3PO4). The reaction mechanism is through a proton transfer from the catalyst to one of the molecule to form a cation, which loses the proton by extracting the OH of the second molecule to form an ether and water.
