Reserved parking in basement, 467-6996 UNL professor discoversfood preserver Experimental slip harvests usable bacterial toxins By Tony Gardner Staff Reporter The discovery of a new, organic way to keep food safe, well-preserved and fresh was recently stumbled upon in a UNL experiment that went wrong. A team led by Bob Hutkins, a University of Nebraska-Lincoln pro fessor of microbiology, was working ,on an experiment that would allow them to ferment meat. However, they ended up with a discovery that aids in food preservation. The process utilizes the ability of a certain bacteria to produce natural defenses that impede other bacteria, which in this case causes food to spoil. While the technology is old, the pro cess has been used in food only re cently, Hutkins said. The process takes advantage of toxins called bacteriocins that are cre ated by a producer bacteria normally used to make fermented foods. The toxins are used to target bacteria that are hazardous to humans and kill off the pathogenic bacteria that cause food poisoning and other disease-caus ing bacteria. “It was just a matter of finding the right bacteria to kill off the disease -44 The simple declaration *no artificial preservatives* provides some marketing advantages. —Hutkins professor of microbiology ---99 - causing bacteria,” Hutkins said. The process was discovered when the first project the group undertook was thought to have failed. The initial project was to use the producer bacteria to ferment a sum mer sausage. The fermentation did not occur, but researchers found that while the producer bacteria did not grow, it produced enough toxins to kill off the pathogenic bacteria. Researchers realized that the dis covery could be used in food where fermentation was not wanted. The process is safe, Hutkins said, and has already been used in foods. The goal of the product is to im prove the shelf life and safety of many kinds of foods and to back up existing safeguards. k SUNDAYS ^V. AT
