Optimization of the Decarboxylation Reaction in Cannabis Extract

The production of cannabis extracts and oils for medicinal and recreational products has increased significantly in North America. This growth has been driven by both market demand in newly legalized states and patient demand for a greater diversity in cannabis products.1,2,3 Most cannabis extraction processes, independent of solvent or instrument choice, undergo a decarboxylation step whereby the carboxylic acid functional group is removed from the cannabinoids. The decarboxylation reaction converts the naturally occurring acid forms of the cannabinoids, e.g. tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA), to their more potent neutral forms, e.g. tetrahydrocannabinol (THC) and cannabidiol (CBD). Because the carboxylic acid group is thermally labile, the industry typically applies a heat source, and at times a catalyst, to decarboxylate the cannabinoids.

A Multiclass Multiresidue Method for Analysis of Veterinary Drugs in Chicken by UHPLC/MS/MS

Veterinary drugs are used in animal production to treat diseases, prevent infection and protect growth of animals, which helps provide quality marketplace. However the uncontrolled use may cause heavy human disease so regulatory agencies around the world have established maximum residue levels (MRLs) or tolerances of veterinary drugs in foods. Drug analysis is generally challenging, due to the complexity of sample matrices and diversity of analytes from various classes of chemical properties. In this study, a fast, sensitive and selective method has been developed for analysis of 73 veterinary drugs (covering 13 different chemical classes) in chicken samples by coupling solvent extraction method with LC/MS/MS.

Determination of Polycyclic Aromatic Hydrocarbons in Seafood by UHPLC- MS/MS

Polycyclic aromatic hydrocarbons (PAHs) can contaminate foods during smoking, heating, and drying processes that allow combustion products to come into direct contact with food. They can also enter food supply chains through contaminated air and water, and accumulate in various food chains. Regulations are in place to monitor PAHs levels in foods; the EU set a stringent maximum residue limit (MRL) for BaP in muscle meat of smoked fish and smoked fishery products at 2 µg/kg.2 In this study, seafood samples were prepared using a QueChERS extraction method followed by a dispersive solid-phase extraction clean-up step. The samples were subsequently analyzed by coupling a UHPLC system with a triple quadrupole mass spectrometer.

Determination of Thirteen Beta Agonists in Pork Using UHPLC - Tandem Mass Spectrometry

Beta-adrenergic receptor agonists (ß- agonists) are synthetic drugs utilized in the treatment of conditions such as asthma in humans, and are also used as a growth-promoting agent in food-producing animals. The use of ß- agonists in food-producing livestock has been either banned or regulated across many countries owing to human health concerns. To aid in the monitoring and detection of ß- agonists in livestock, a highly sensitive and selective analytical method has been developed, and is presented in this study. This LC/MS/MS method details the analysis of 13 ß- agonists in pork samples, and utilizes isotopically-labeled internal standards to compensate for matrix effects present in complex food matrices.

Determination of 24 Polycyclic Aromatic Hydrocarbons in Smoked Meat by ASE Extraction-GPC Purification Coupled with GC/MS

Polycyclic aromatic hydrocarbons (PAHs), a class of complex compounds containing two or more benzene rings, are widely found in the environment and food. PAHs are formed during the incomplete combustion of organic matter, such as wood utilized in cooking and food preparation. They have attracted wide attention due to studies which have shown the teratogenicity and carcinogenicity of PAH compounds. For humans, food intake is one of the main sources of PAH exposure, and can be the result of contamination from anthropogenic sources, food processing or cooking practices. In this paper, a validated method employing accelerated solvent extraction (ASE) and gel permeation chromatography (GPC), followed by solid phase extraction (SPE) on silica and analytical determination by GC/MS was applied for the detection of PAHs in smoked meat. The results demonstrate that the method is suitable for the simultaneous determination of 24 PAHs in smoked meat with good efficiency, accuracy and reproducibility.

In this study, we demonstrate the accuracy and precision (CCß validation study) of the simultaneous 5-in-1 sample extraction method by manual ELISA and DS2 automation methods. Sensitivityof the assay kits (LOD) was also demonstrated using manual and DS2 method. Finally, sample variability testing was performed to characterize the effects of matrix from various shrimp sources.

Determination of the Nitrofuran Metabolites in Seafood using Ultra High-Performance Liquid Chromatography - Tandem Mass Spectrometry

Nitrofurans are a class of broad-spectrum antibiotics that are widely used to kill or slow down the growth of bacteria in the aquaculture industry. The use of nitrofurans and their metabolites has been restricted by a number of countries and organizations within the European Union, United States and China, due to their harmful side effects to human health, and a Minimum Required Performance Limit (MRPL) 0f 1.0 µg/kg has been set for food, animal and aquaculture products. LC/MS/MS methods have been used for the detection of nitrofuran metabolites in many studies owing to the high sensitivity, selectivity and specificity of the methods. However, nitrofuran metabolites demonstrate low ionization efficiency with the electrospray ion source used in LC/MS/MS systems. Therefore, the use of a derivatization step for nitrofuran metabolites before extraction and LC/MS/MS analysis is crucial to meet the low regulatory limits of 1.0 µg/kg in food samples. The main purpose of this work is to determine the detection limits for nitrofurans using QSight® 210 LC/MS/MS system.

Malt (kilned) method - RVA 16.04

The method is first used to establish the malting potential calibration for the variety of interest. To do this, a number of malts varying in known malting potential for the selected variety are tested. From the viscograms, the peak viscosity, time to peak, breakdown, peak area, holding strength and final viscosity are measured. These parameters are fitted as dependent variables against conventional measures of malting quality using standard regression techniques. The loge transformation may be used as appropriate. The most highly correlated viscogram parameters may subsequently be measured in malts of unknown potential for the same variety, using the regression equation to predict the potential malting quality of the sample. Good correlations using loge time to peak and loge peak area have been demonstrated.

Analysis of Mycotoxins in Multi-Grain and Corn Cereals

Mycotoxins produced by fungi as toxic secondary metabolites, leave grains, maize and cereals particularly vulnerable. With this in mind, and considering that an estimated 25% of all crops show some signs of mycotoxin contamination, many countries have established regulatory guidelines for maximum mycotoxin limits in not only feed and grain, but also in processed food products.

Determination of Mycotoxins in Cereals by LC/MS/MS with Online SPE

Mycotoxins are toxic secondary metabolites produced by fungi, and are capable of causing disease and death in both humans and animals. Sample preparation is a critical step in the successful analysis of mycotoxins in food matrices. The "dilute and shoot" approach is a quick and easy way to introduce the sample into the LC/MS/MS analysis. However, due to the complexity of food matrices, this approach will often result in irreproducible matrix effects. To overcome these problems and improve sensitivity, this application note details the use of online solid phase extraction (SPE), coupled to an LC/MS/MS system for sample enrichment.

Arsenic Speciation Analysis in Rice Following Method GB 5009.11-2014 to Ensure Safety

Rice represents a dietary staple for over half of the world's population. However, in recent years, concerns have been raised over the presence of high levels of arsenic (As), where this carcinogenic metalloid can be accumulated at levels far exceeding ambient concentrations. Since China is the world's largest producer of rice, the Chinese government released a national standard method in 2014 for food safety – GB 5009.11– to aid the evaluation of As species in rice and rice products. In this document, HPLC-ICP-MS is identified as the preferred analytical technique. In this study, five arsenic species were characterized in a commercial rice sample and certified reference material using a gradient anion-exchange method in accordance with GB 5009.11. The analysis was performed using a PerkinElmer NexSAR™ HPLC-ICP-MS speciation solution, consisting of a NexSAR inert HPLC coupled to a NexION® ICP-MS.

Fast Digestion Analysis of Lead and Cadmium in Rice Using Graphite Furnace Atomic Absorption

Lead (Pb) and cadmium (Cd) are common pollutants in grains and are extremely toxic. Pb is harmful to human organs even at trace levels, and once it accumulates in the body, it causes inhibition of hemoglobin formation and neurological disorders. Cd is even classified as human carcinogen [Group 1 - according to International Agency for Research on Cancer]. It is reported that Cd leads to severe kidney problems which can be fatal and is also associated with brittle bones and liver problems. Rice, as the most widely consumed cereal grain in Asia/China, can quickly pick up Pb and Cd from toxins, pesticides and fertilizers in the soil, thereby endangering the health of millions of people through their diet. Therefore, it is extremely important to develop a simple, reliable method to monitor the levels of Pb and Cd in rice. According to Chinese national standard GB 2715-2016 Hygienic Standard for Grain, the maximum concentrations of Pb or Cd in grains must be below 0.2 mg/kg; the allowable level in the European Union is the same [EC 1881/2006]. The official technique for the determination of heavy metals in both cases is graphite furnace atomic absorption spectroscopy (GFAAS, GB/T 5009. 12-2017, GB/T 5009-2017. 15 and EN 14083:2003). Samples can be pretreated using various methods, including microwave digestion, hot block digestion, dry ashing, and hot plate digestion. It is found that these conventional digestion procedures are always complicated and time-consuming (two-four hours or even longer). Plus, conventional sample preparation techniques require large quantities of corrosive and oxidizing reagents, increasing the chance for contamination which could lead to inaccurate results. Special PTFE vessels are needed for microwave digestion; however, reusable utensils might also cause cross contamination.

Fast Digestion Analysis of Lead and Cadmium in Rice Using GFAAS with Deuterium Background Correction

Toxic elements, such as lead (Pb) and cadmium (Cd), are entering the food chain through environmental contamination. Rice, as the most widely consumed cereal grain in Asia, can quickly pick up Pb and Cd from soil, thereby seriously endangering human health through diet. These toxic element levels need to be carefully monitored. Maximum levels of Pb and Cd are strictly regulated in Asian countries, especially in China; therefore, it is extremely important to develop a simple, reliable method for trace levels of Pb and Cd in rice. The allowable maximum levels of Pb and Cd in grains in EU and China are required to be below 0.2 mg/kg (Commission Regulation EC 1881/2006 and Chinese GB 2715-2016 Hygienic Standard). Graphite furnace atomic absorption spectroscopy (GFAAS) is the officially recommended technique for detection of trace elements in various food stuffs (GB/T 5009.15-2017, GB/T 5009. 12-2017 and EN 14083:2003). Food samples are usually pretreated before GFAAS analysis using various methods: microwave digestion, hot block digestion, dry ashing, and hot plate digestion. These conventional digestion procedures are usually complicated and time-consuming (2-4 hours or longer). Plus, they require large quantities of corrosive and oxidizing reagents, increasing the chance for contamination which could lead to inaccurate results. However, fast digestion can effectively speed up the sample preparation procedure while reducing the use of corrosive reagents and the chance for contamination.
