Abstract

The changes of people consumtion patterns demands a healthier bread product and tends to be organic food without use synthetic food additives that brings various consequences to health. This condition leads to the development of food additives which has effectiveness equivalent to synthetic food additive but safe for health especially if consumed long term. Lactic acid bacteria is a bacteria that hass been widely used in fermented food production process. Making bread using lactic acid bacteria begins with sourdough or acid dough consisting of flour and water fermented with lactic acid bacteria either derived from a particular natural contaminant from flour or from a starter culture containing one or more known lactic acid bacteria. Various product of actic acid bacteria metabolism such as lactic acid, acetic acid, exopollysaccharide and antimicrobial compounds such as bacteriocin make lactic acid bacteria application in baking process have to the potential to improve microbiological quality and bread shelf-life. This research aims to study the effect of lactic acid bacteria addition as a natural preservative in the baking process. The ability of lactic acid bacteria to evolve naturally from fermented flour and water promises the potential for easy sourdough preparation and can be used continuously as  a natural preservative that will save production cost. The parameters to be determined include evaluation of lactic acid bacteria and yeast growth on dough and determination of moisture content as well as total bacteris, mold and E.coli an bread. Key words: bread, lactic acid bacteria, preservatives, shelf-life, food safety
