Nowadays consumers are looking for “natural” food ingredients for keeping them healthy and fit in all foods. “An Organic Natural Microbial Inhibitor” is an organic antimicrobial ingredient that is synthesized from the fermentation of natural raw materials including rice flour, wheat hydrolysate and corn steep liquor. An amount of 0.1 to 1.5% during preservation of different food products like pickles, salads, beverages, and meat etc., keeps the food free from the microbial contaminations, increases flavor, and meat tenderness. It is produced through co-fermentation of Acetobacter aceti and Lactobacillus delbrueckii that are modified by way of strain improvement through medium optimization experiments. The major ingredients of the product include combination of naturally produced organic acids like acetic, lactic and propionic acids in addition to other acids in trace amounts in liquid form and also in powdered form. These are in combination responsible for the antimicrobial property with simultaneous flavor enhancement.
