Additives meant to protect vitamin C actually cause more harm

The water-repellent agents, which act like raincoats, are mobile, Lipasek said. When they move around, they clump together and leave some of the vitamin C uncovered. When that happens, moisture is able to reach and degrade the exposed vitamin C.
The moisture-absorbing agents, which absorb the water at a lower humidity than vitamin C, may be absorbing so much moisture that they become saturated. When that occurs, Mauer said, the pH level around the vitamin C can change, or water can move and interact with the vitamin C. Both of these scenarios could lead to further reactions that lower the humidity at which vitamin C deliquesces and changes from solid to liquid. Once the vitamin C dissolves, it is unstable.

The FDA Food Safety Modernization Act: The Biggest Impact to Food Safety Policy in Over 70 years

On January 4, 2011, President Barack Obama signed into law a new federal statute called the FDA Food Safety Modernization Act (H.R. 2751).  The FDA Food Safety Modernization Act is divided into four areas: prevention of food safety hazards, detection of and response to food safety problems, improving the safety of imported foods, and miscellaneous provisions. The new law provides greater authorization for the Food and Drug Administration (FDA) and the Secretary of Health and Human Services (HHS) to increase inspections of many domestic food facilities, enhance detection of foodborne illness outbreaks, and order recalls of contaminated food products.  The new law requires most food companies to write and implement new safety protocols to control or eliminate potential foodborne hazards.   More oversight of imported food products is also included in the law and more provisions are in place to deny entry of food products into the U. S. under certain circumstances.   The FDA Food Safety Modernization Act is the most significant update of U.S. food safety laws since adoption of the U.S. Federal Food, Drug, and Cosmetic Act in 1938.

Nanoparticle gives antimicrobial ability to fight Listeria longer

Yuan Yao, an assistant professor of food science, altered the surface of a carbohydrate found in sweet corn called phytoglycogen, which led to the creation of several forms of a nanoparticle that could attract and stabilize nisin, a food-based antimicrobial peptide. The nanoparticle can then preserve nisin for up to three weeks, combating Listeria, a potentially lethal foodborne pathogen found in meats, dairy and vegetables that is especially troublesome for pregnant women, infants, older people and others with weakened immune systems.

New CDC Data Provides Insight About Foodborne Illness Challenges and Interventions

The most recent data from the Centers for Disease Control and Prevention (CDC), relative to foodborne disease outbreaks in the United States, was published this past summer in the Morbidity and Mortality Weekly Report (MMWR).  CDC still estimates a total of 76 million illnesses occur annually in the United States, which amounts to nearly 1 in every 4 people.  The most recent report provides information as to the causes of foodborne illness and types of foods implicated in foodborne illness incidents in the year 2007.

Udit Minocha... Difference Maker

Udit Minocha

The war he fights today: It’s against E. coli contaminations in spinach and lettuce. His experimental weapons are bacteria, which are proving effective as E. coli killers. The immediate battlefront is prevention. The goal is to figure out how to use the bacteria to prevent the contamination without making the lettuce and spinach brown and unappealing to grocery shoppers.

E. coli thrives near plant roots, can contaminate young produce crops

E. Coli on plant root

Purdue scientists added E. coli to soil through manure application and water treated with manure and showed that the bacteria can survive and are active in the rhizosphere, or the area around the plant roots, of lettuce and radishes. E. coli eventually gets onto the aboveground surfaces of the plants, where it can live for several weeks. Activity in the rhizosphere was observed using a bioluminescent E. coli created by Bruce Applegate that glows when active.

Student conducts antimicrobial research

High PLains/Midwest Ag Journal

Arun Bhunia

Arun Bhunia, a professor of food science, and Kristin Burkholder, a former Purdue graduate student who is now a postdoctoral researcher in microbiology and immunology at the University of Michigan Medical School, found that listeria, even in low doses, somehow triggers intestinal cells to express a new protein, heat shock protein 60, that acts as a receptor for listeria. This may allow the bacteria to enter the cells in the intestinal wall and exit into a person's bloodstream. Bhunia and Burkholder's findings were published in the early online version of the journal Infection and Immunity.

Purdue Outstanding Food Science Awards given

Five professionals received Outstanding Food Science Awards on October 7th from Purdue University's Department of Food Science.

Global problem solver

Morgan Goodall

Morgan is figuring out how to lower import costs for countries that don’t have their own wheat, for bread “By reducing the amount of wheat needed in bread, and replacing it with sorghum, which is readily available, the cost decreases thus reducing economic strain on these countries. I am looking at ways communities can incorporate crops they can grow into their daily diet.”
