General description
Starch is a naturally occurring, abundantly available, and biodegradable polysaccharide. It is stored in the various parts of the plant such as roots, leaves, stems, tubers, fruits, and pollen grains. Corn starch is made up of 25% amylose and 75% amylopectin.[1]
Application
Starch from corn has been used for the evaluation of amylose content in bananas for standard curve preparation. It has also been used in hydrolysis studies via in vitro fermentation using pig fecal inoculum.[2]
Biochem/physiol Actions
Starch facilitates the storage of energy in plants. Corn starch has a wide variety of applications like paper bags, stationery, tissues, manufacturing antibiotics, and drip-feed systems. It can also be used in increasing the stiffness of the fabric and improve its appearance. Corn starch is also a part of human and animal diets.[1]
