Departments: Certified Wheat Seed Ensures Quality of the Loaf
When it comes to food ingredients, few food manufacturers can match the quality assurance and traceability claims of Warburtons, the United Kingdom’s largest independent baker.
Departments: Lessons Learned from GFSI Audits
Achieving GFSI (Global Food Safety Initiative) certification can ensure consumer confidence in product safety. Among the many existing standards available for audit or certification, GFSI has selected several that are applicable to the food manufacturing industry.
Features: A Key Figure in Food Safety
Mention the name Louis Pasteur (1822-1895), and most people think of the pasteurization process he invented to prevent beverage spoilage. But Pasteur was a true renaissance man, researching, teaching chemistry and physics, and ultimately making discoveries that revolutionized fields such as agriculture, hygiene, and industry.
It’s often said that the future is now, which may explain why so many people are unprepared for it.
Departments: The Latest in Lab Equipment
As this issue’s Product Focus shows, laboratory equipment for food science and the industry is changing rapidly. As the cover story for our December/January 2009 issue reported, one of the key changes in the lab is the emergence of tools that are more efficient, reliable, and automated, said Purnendu Vasavada, PhD, an extension food safety and microbiology specialist with the University of Wisconsin-River Falls. The lab will also be smaller.
In recent years, the focus on the environmental quality of the food production landscape has increased. Although far from being a new problem, high-profile cases resulting in sickness and death traced back to the manufacturing process have caused the industry to reassess contamination control strategies, an issue currently under discussion in the Senate and inherently linked to food safety. Some level of contamination control naturally already exists and, given the diversity in environmental production...
Departments: Get a Documented Food Safety Plan
Get ready to meet your new Food and Drug Administration (FDA) inspector. On Jan. 4, 2010, President Obama signed into law the Food Safety Modernization Act, S. 510. The bill essentially takes provisions from the House-passed H.R. 2749 and combines it with S. 510 (Senate) to make one bill. The new bill will impose stiff penalties for known violations. To ensure enforcement, the House bill includes a minimum $1,000/year registration fee to be assessed to all food facilities to help pay for mandatory FDA...
Departments: The Microbiology of Cereals and Cereal Products
Bacteria are frequent surface contaminants of cereal grains. For bacteria to grow in cereal grains, they require high moisture or water activity (aw) in equilibrium, with high relative humidity. Generally, bacteria are not significantly involved in the spoilage of dry grain and become a spoilage factor only after extensive deterioration of the grain has occurred and high moisture conditions exist. However, bacterial pathogens and spoilage bacteria, such as spore-forming bacteria that cause ropiness in...
Higher nutrient levels are a much-touted benefit of organic fruits and vegetables, but a recent study casts doubt on that idea. Researchers from the National Food Institute at the University of Copenhagen in Denmark put the antioxidant content of organic potatoes, onions, and carrots to the test and found them no better than their conventionally grown counterparts. The research was published in the Journal of Agriculture and Food Chemistry.
Departments: Advances in LC/MS for Food Safety Testing
In recent years, the utilization of liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS) has grown rapidly and is now widely recognized as an ideal, highly specific, and extremely sensitive technique for testing food products with superior accuracy and higher throughput than other methods such as LC/ultraviolet, LC/fluorescence, or microbiological and enzyme-linked immunosorbent assay methods.
