food contamination News
Quiet in the Peanut Gallery!
Jun 15, 2015 — If you have a peanut allergy, you’re in for a bad time. A constant state of alert is status quo, with typical culprits (like peanut butter, peanut flour and peanut oil) on the blacklist and other, more subtle threats (like chocolate, pastries and candy) flirting with the prohibition. Even lawn fertilizer has been known to contain peanut hulls. Being the watchdog for this kind of danger is not easy, especially when vague warnings of “May contain peanuts” abound. Recent
Gold nanoprobes + FRET = cancer insights
GLASGOW, Scotland – Gold nanoprobes paired with FRET (Förster resonance energy transfer) microscopy could allow researchers to study cancer cells in more minute detail and measure the effectiveness of medicines at subcellular levels. Gold nanoparticles have...
Gold Probes Offer Insight into Cancer
GLASGOW, Scotland, June 25, 2013 — Gold nanoprobes paired with FRET microscopy could yield a new generation of biological imaging and sensing techniques capable of studying cancer cells in minute detail, measuring the effectiveness of medicines at subcellular levels and identifying...
iTube Detects Allergens via Cellphone
LOS ANGELES, Dec. 19, 2012 — Want to avoid blowing up like a balloon eating prepackaged food that may contain harmful food allergens? Well, thanks to a smartphone application that can test food samples for life-threatening allergens on the spot, you can do just that.
Optical Filters Take Food Inspection to a Whole New Level
Jul 1, 2011 — Multispectral machine vision systems are one way to speed up quality control on production lines – and to make sure our food is safe for consumption. Foodborne diseases affect approximately 48 million people in the US each year, according to...
New Method Manipulates Particles
WEST LAFAYETTE, Ind., June 22, 2010 — Researchers at Purdue University have developed a potential new tool for medical diagnostics, for testing food and water for contamination and for crime scene forensics. The novel technique uses a combination of light and electric fields to position...
Food safety just got smarter
KINGSTON, R.I. – The hot-button issue of food contamination, it seems, is never far from the headlines, but until now, avoiding it has depended to a great extent upon the decidedly low-tech expiration date. However, thanks to technology developed by Brett Lucht and...
UV Light Detects Salmonella
AMES, Iowa, Feb. 3, 2009 – After the recent outbreak of Salmonella in the US, which has sickened more than 500 people and killed eight, the federal government has launched a criminal investigation that will be carried out by the FDA’s criminal division and the Department of...
How Safe is Your Meat? Spectroscopy Knows
Jul 30, 2008 — At a time when food prices are soaring and tales of contamination make headlines, consumers expect not only value for their food dollars, but assurances that what they buy is fit to eat. Optical means, especially laser spectroscopic methods, are one...
