      • Maize starch<\/strong>\u00a0is produced by the wet milling process, which involves the grinding of softened\u00a0maize<\/strong>\u00a0and separation of\u00a0corn<\/strong>\u00a0oil seeds (germs), gluten (proteins), fibers (husk), and finally\u00a0pure <\/strong>starch<\/strong>.\n
          \n
        • \u200bCorn starch<\/strong> is made from maize<\/strong> kernels<\/strong>, which are high in starch<\/strong>.<\/strong><\/li>\n\n\n\n
        • Corn starch<\/strong> has a wide variety of applications. It is used<\/strong> as a thickening agent in soups<\/strong>.<\/li>\n\n\n\n
        • Corn starch <\/strong>is also used in manufacturing bio-plastics<\/strong> and the preparation of corn<\/strong> syrup<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
        • The general way to Produce Biodiesel<\/strong>\u00a0fuels is\u00a0transesterification of fat<\/strong>\u00a0or\u00a0oil triacylglycerols<\/strong>\u00a0with short-chain alcohol such as\u00a0methanol or ethanol<\/strong>\u00a0in the presence of alkaline or acid catalysts.\n
            \n
          • Corn Biodiesel<\/strong> chemically is a mixture of long-chain fatty acid methyl esters (FAMEs)<\/strong>.<\/li>\n\n\n\n
          • Oil extracted from maize<\/strong> that can be converted into ethanol or biodiesel<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
          • The type of alcohol<\/strong> in the alcoholic<\/strong> drinks<\/strong> we drink is a chemical called ethanol. To make alcohol<\/strong>, you need to put grains, fruits, or vegetables through a process called fermentation<\/strong>, the common source of ethanol is maize <\/strong>and other grains.<\/li>\n<\/ul>\n\n\n
