They exposed samples of yogurt and low-fat Cheddar cheese to phosphoric acid and found that the survival of L. casei 334e was greater in the cheese compared to the yogurt. This suggests that the cheese would be better at delivering L. casei 334e because it allows the probiotic’s cells to better withstand low pH conditions that are present in the stomach, reported the researchers.
The study, "Comparative Evaluation of Yogurt and Low-Fat Cheddar Cheese as Delivery Media for Probiotic Lactobacillus casei," appeared in the September 2008 issue of Journal of Food Science. For more information, visit www.ift.org, and click on "Publications."
USDA examines label use
The U.S. Dept. of Agriculture’s Economic Research Service has published a report that details consumer use of nutrition and ingredient labeling when making food purchases. The report tracks the time period from 1995—just after nutrition labeling became mandatory under the Nutrition Labeling and Education Act—to 2006. One important finding was that while a majority of consumers report using nutrition labels when buying food, use has declined for most label components, including the Nutrition Facts label and information about calories, fats, cholesterol, and sodium.
The report, "The Decline in Consumer Use of Food Nutrition Labels, 1995–2006," is available at www.ers.usda.gov/Publications/ERR63/ERR63.pdf.
ConAgra reduces waste
For the past several years, there has been a heightened awareness of becoming more "green," increasing recycling efforts, and making overall lifestyle changes in the name of environmentalism. Industry is evaluating environmental initiatives as a way to remain competitive. So it is no surprise that ConAgra Foods, Omaha, Neb., has decided to incorporate post-consumer recycled plastic in most of its frozen meal trays, a move that may help eliminate approximately 8 million lb of plastic from landfills.
Most frozen meal trays used by food manufacturers are made of crystallized PET plastic, which is made from newly produced plastics and takes more energy to produce. ConAgra is using 30–40% post-consumer recycled plastic. The company teamed with Associated Packaging Technologies to apply a new technology that cleans recycled plastic for use in the trays. The Food and Drug Administration has approved the trays as direct food contact materials.
ConAgra, which reports that it is the only company in North America to use post-consumer recycled plastic in frozen meal trays, began transitioning to the new trays in June 2008 and is currently rolling them out in stores.
Reducing allergic reactions to milk
Milk allergy is a common childhood food allergy. According to the Asthma and Allergy Foundation of America, 2–5% of children experience allergic reactions to milk in the first year of their life. While many of these children outgrow the allergy by age 3, some remain allergic throughout adulthood.
Extensively heating cow’s milk may help children with milk allergies to tolerate it, according to research published in the Journal of Allergy and Clinical Immunology. Researchers from Mount Sinai School of Medicine, New York, N.Y., reported that high heat mostly destroys certain milk proteins recognized as foreign by the immune system. Thus, the researchers believed that some children with milk allergy would be able to tolerate extensively heated (baked) milk products. They gave 100 children with milk allergy heated milk products. Those who tolerated the heated milk were then given unheated milk. From there, they gave heated milk products for 3 mo to subjects who were heated milk–tolerant and unheated milk–reactive and then re-evaluated them. Out of the 100 children (age range 2.1–17.3 years), 68 tolerated extensively heated milk only, 23 reacted to heated milk, and nine tolerated both heated and unheated milk.
The study, "Tolerance to Extensively Heated Milk in Children With Cow’s Milk Allergy," appeared in the August 2008 issue of Journal of Allergy and Clinical Immunology.
Bill addresses food safety
Responding to recent recalls as well as to cases of foodborne illnesses, U.S. Senators Dick Durbin (D-IL), Judd Gregg (R-NH), and Richard Burr (R-NC) recently introduced a bipartisan bill to reform the way the Food and Drug Administration protects the safety of the nation’s food supply.
The bill, The FDA Food Safety Modernization Act (S.3385), authorizes new science-based standards for the safety of produce; increases the frequency of inspections of all food facilities; establishes a new pilot program for tracking and tracing back fruits and vegetables in the event of a foodborne illness; and gives FDA mandatory recall authority in the event a company fails to recall a product at FDA’s request.
FDA schedules meeting
The Food and Drug Administration has scheduled a public meeting to discuss product tracing systems for fresh produce. The purpose of the meeting is to stimulate and focus a discussion about mechanisms to enhance product tracing systems for fresh produce and to improve FDA’s ability to use the information in such systems to identify the source of contamination associated with fresh produce-related outbreaks of foodborne illness.
The meeting will be held on Nov. 13, 2008, in Oakland, Calif. More information about the meeting (docket no. FDA-2008-N-0513) is available at www.cfsan.fda.gov/~comm/regist10.html.
