Food scientists have long known that, when heated, sodium nitrite, a chemical used to preserve bacon and other processed meats, has a tendency to combine with other naturally occurring particles to form nitrosamines. Laboratory studies have found that animals fed high doses of nitrosamines developed cancer.
In fact, concern over the presence of nitrosamines in food and its link to cancer led USDA officials, during the late 1970s, to consider banning the use of sodium nitrite altogether.
During this period, research was launched to isolate compounds capable of inhibiting the formation of these carcinogens. The work, which culminated with the recent approval of alpha tocopherol, was conducted by Hoffman-La Roche Inc., with USDA supervision.
The Nutley, N.J., company has made this newest additive available to the food industry, and the substance can now be applied to the surface of the more than 1.5 billion pounds of bacon sold annually in the United States.
Additionally, the company plans further research into other areas where vitamin derivatives can be used to preserve food and inhibit potentially harmful substances.

ASPARTAME GETS ANOTHER VOTE OF CONFIDENCE FROM THE GOVERNMENT.
The U.S. Food and Drug Administration has approved the use of the controversial low-calorie sweetener aspartame in four more food and beverage groups, the NutraSweet Co. says. The FDA gave the go-ahead for aspartame,
marketed as NutraSweet, to be used for refrigerated juices in ready-to-drink,
concentrated and frozen packages; ready-to-eat frozen desserts on a stick; breath mints, and ready-to-drink teas in can or concentrated form. Also last week, the FDA rejected a claim from consumer lawyer James S. Turner that aspartame may cause seizures and should be banned from grocery shelves. Turner says he will appeal the agency's ruling through the FDA or the courts.
THE NATIONAL RETAIL BEEF-PRICE AVERAGE INCREASES SLIGHTLY.
According to the monthly survey of supermarket beef prices by the National Cattlemen's Association, the average price of five cuts of beef was $2.40 per pound on Nov. 13, compared with $2.39 in October. November's price was three cents lower than prices for November 1985. The association reported that the
average retail price remained steady because there was little fluctuation in wholesale prices. The average per-pound prices for November were ground beef, $1.29; round steak, $2.37; sirloin steak, $2.91; T-bone steak, $3.87, and chuck roast, $1.57.
CONSUMERS MAY SEE CHANGES IN PROCESSED MEATS.
Consumers could see leaner hot dogs, bologna and other cooked sausage products under a proposal to allow processors to use more water in their recipes, the Agriculture Department said. The proposal would allow processors to increase the amount of added water in cooked sausage products above the current limit of 10 percent. As a result, water would replace fat, thus lowering the fat content. Labels of meats prepared under the proposed rules would have to comply with the department's new labeling policy, which regulates use of the labeling terms "lite," "light," "leaner" and ''lower fat." Comments on the proposal can be sent by Jan. 23 to: USDA, Food Safety and Inspection Service, Regulations Office, Attn: Linda Carey, Hearing Clerk, Room 3168-S, Washington, D.C. 20250.
