PIROLISIS PEMBUATAN ASAM CAIR DARI BONGGOL JAGUNG SEBAGAI PENGAWET ALAMI PENGANTI FORMALIN (Pyrolysis Making of Acid Liquid Natural Corncobs as a Preservative Substitute Formalin)

Abstract

Maize (Zea mays L.) is one of the world's most important food crops, other than wheat and rice. Indonesia as a predominantlyagricultural country as one made of corn a staple food, and cornproduction are evenly distributed throughout the country. pyrolysis is a process of conversion of organic materials at high temperatures and break down into smaller molecules bond. This process generates organic vapors, pyrolysis gases and charcoal. The resulting organic vapor containing carbon monoxide,methane, carbon dioxide, which is easy menguap dan tar water. Organic vapor then condensed into a liquid. Known as the liquidpyrolysis bio-oil. Trial manufacture of beef meatballs preservation of liquid smoke corncobs using fixed variables, namely the weight of raw materials as much as 3 kg of corn bongo. The independent variable used is the time used is 1 hour and2 hours. With heacquisition acquisition densitas1, 144 g / ml and 1, 072gr/ml,while viskositas1, dan1 cp 284, cp 1073, to. Then the liquid smoke in the test organoleptiknya. Orgaleptik test covers the smell, shape, color, and a sense of organoleptic tests carried outuntil the seventh day. Test by using a comparison of beef meatballs that have been diberioleh formalin.
