Starch is composed of two glucose polymers, namely amylose and amylopectin. Amylopectin with its multiple branched chains of (1-4)-R-glucans interlinked by (1-6)-R-linkages is usually the major component of starch, with the essentially unbranched amylose making up the minor fraction. Starch molecules (called starch granules) are usually deposited in plants in the form of discrete semi-crystalline aggregates, which are the most important energy reserve in plants.
During grain development, starch granules of different sizes and shapes accumulate in the endosperm. They are large, disc-shaped A particles, and small spherical B particles. The average diameter of A-type granules is 10 to 35 μm, and the diameter of B-type granules is less than 10 μm, accounting for more than 90% of the total number of starch granules. Large A-type and small B-type starch granules have different physical, chemical and functional properties. The size of starch granules directly affects the crystallization properties, digestion properties, modification results and thermodynamic properties of starch. Analysis of starch granules size is hence very important.
