However, engineering genetically stable, controlled, precise production of a combination of specific flavorants in any industrial food-processing agent has remained a formidable challenge.
Further to these are food-processing agent residues, food contact material migrants, contaminants formed during the cooking of food, indirect food additives, as well as a wide array of naturally occurring mutagens and carcinogens that are normal constituents of foods.
Second, incorporating large (i.e., >10 kb) genetically stable DNA constructs into brewer's yeast has not been reported, and is complicated by their ploidy as well as concerns regarding the incorporation of selection markers in food-processing agents.
Additionally, FPL can be used to perform mathematical calculations on agents spreading within food processing chains by the application of the "Agents" node.
This procedure is of particular relevance in the food industry, where ozone is applied as an antimicrobial agent and food processing frequently includes heating steps.
The Food and Drug Administration signed off on the use of ammonia, concluding it was safe when used as a processing agent in foods.
The use of natural antibacterial agents in food processing and food preservation has played a vital role in controlling the adverse effect of bacteria in food.
Hydrogen peroxide (H2O2), an important oxidizing, bleaching, and sterilizing agent, is widely used in food processing, pulp and paper bleaching, sterilization, liquid-based fuel cells, and clinical applications [1 7].
Aluminium products are used extensively in food processing [ 18], for example, as anti-caking agents, though there is no indication that they are being used in this way in powdered milk formulas.
Chlorine dioxide (ClO2) gas is a powerful oxidizing agent in many industrial applications for food processing, drinking water and cleaning treatments.
Phages have been suggested as alternative anti-microbial agents for a variety of pathogenic bacteria found in food processing environments [ 19- 23].
