Bt corn is a variant of maize that has been genetically altered to express one or more proteins from the bacteria Bacillus thuringiensis. The protein is poisonous to certain insect pests and is widely used in organic gardening. The European corn borer causes about a billion dollars in damage to corn crops each year.
Corn starch has two major components, amylose (a straight chain polymer of glucose) and amylopectin (a branched chain polymer of glucose). In natureâfor example, in cornâit is found structurally in a granule.Corn starch is âstickyâ. But, when you extract the starch from corn and then use it as a food ingredient, it quickly loses that stickiness when heated. And it can cause bakery products to become stale.orn starch has two major components, amylose (a straight chain polymer of glucose) and amylopectin (a branched chain polymer of glucose).
