Fast, accurate, and robust solution for routine commercial cannabis testing

As the world debates cannabis legalization for therapeutic applications and recreational use, the trends are shifting.  Medicinal use of cannabis is legal in an increasing number of countries worldwide, including 33 states and the District of Columbia in the United States. Uruguay was the first country in the world to legalize the sale, cultivation, and distribution of cannabis in 2013. In the United States, Washington and Colorado were the first to fully legalize cannabis in 2012. By the end of 2019, 10 states have legalized recreational use for adults over the age of 21, with 64% of Americans favoring the move

Don’t judge a nutritional supplement by its label, as often, government monitoring of ingredients begins after the product enters the consumer market1. Meanwhile, there may be additional additives not mentioned on the label as they are used to address supplement side effects. Such is the case in the United States where even though federal law requires supplements to carry a dietary supplement label or a substitutional term, monitoring begins once a supplement is on the market. In China meanwhile, the China Food and Drug Administration’s (CFDA) health product potential illegal additives list, clearly stipulates monitoring processes for additives in six different types of nutritional supplements including weight loss, blood sugar reduction, blood pressure reduction, anti-fatigue, sleep improvement and immune strengthening functions.Read Tech Note >

Up until recently, SWATH® Independent Data Acquisition (IDA), was not widely used for the detection of pesticides in food samples. Introduced in 2012, SWATH Acquisition is an advanced acquisition technology capable of running on high-resolution mass spectrometers such as the X500R QTOF system or Triple TOF technology. Originally used in the Omics market to ID and quantify complex samples, SWATH Acquisition is gradually making a transition across markets including the investigation of pesticides in food. Like designer drugs, pesticides continuously undergo synthesizing, and food labs are beginning to require a more reliable analysis method to be confident in their resulting reports.

A recent study published by the Annals of Allergy, Asthma, and Immunology (ACAAI), pointed out, in a study of 109 people tested, that skin prick tests are not 100 percent reliable. In the study, participants were subjected to oral food challenges prior to skin testing in which 50 percent of individuals had no reaction. It was also discovered that blood tests were not full-proof even though they measure the presence of IgE antibodies to specific foods. These results are not surprising given that 50 to 60 percent of tests result in false-positives.

The EU Reference Laboratory (EURL) for Fruits and Vegetables in Almería is responsible for a network of around 200 laboratories which provide essential surveillance and monitoring to ensure the safety of foodstuffs available across Europe. The EURL provides proficiency testing and method development for these official laboratories, ensuring rigorous screening to avoid harmful chemicals entering the food chain

Adding colorful dyes to food is nothing new. In the early 19th century, for example, it wasn’t uncommon for manufacturers to add chalk to white bread, thicken milk with a lead compound, and inject red dye into meat in the quest for a fresher appearance1. Fast forward to the 21st century, however, and along with mass spectrometry, food standards have come a long way. Foods now must pass muster according to standards set by government regulators or else risk fines and punishment which can be costly for the manufacturer.  To support these measures, are agencies such as the US-FDA, EFSA, and others which have banned some colors due to their toxic and carcinogenic nature which brings me to mass spectrometry analysis. Discover more when you read the following application note, “LC-MS/MS Analysis of Emerging Food Contaminants,” in which researchers used the ExionLC AD with a Phenomenex Column for sample separation followed by MS/MS detection with the SCIEX X500R QTOF system.
