Testing for the levels of pesticide and mycotoxins in cannabis is important to ensure consumer safety and quality control. In this work, the PerkinElmer application development team analyzed all 66 pesticides (including very hydrophobic and chlorinated pesticides typically analyzed by GC-MS/MS) and five mycotoxins spiked in cannabis flower extracts well below the action limits specified by the state of California. A LC-MS/MS instrument was used with ESI and APCI sources and a simple solvent extraction method with excellent recoveries for all analytes in acceptable range of 70-120%.
Liquid chromatography-tandem mass spectrometry (LC/MS/MS) has become the method of choice for pesticide. The state of Oregon has issued regulatory limits for 59 pesticide residues in both cannabis flower and concentrates, while other states have come up with their own lists of pesticide residues relating to medical marijuana and cannabis testing.
Solvent such as supercritical CO2, butane, propane, other hydrocarbons, water, or alcohol are used to extract out the cannabinoids and terpenes from the plant material. In some cases, the solvent and impurities from the solvent remain in the extracted material. This study will shows the analysis of residual solvents using pressure-balanced headspace (HS) sample introduction coupled with Gas Chromatography/Mass Spectrometry (GC/MS). Unambiguous separation of all compounds is obtained while maximizing sample throughput.
This application describes the sample preparation and analytical method for the chromatographic separation and quantitative monitoring of twelve primary cannabinoids in the extracts of several food matrices by HPLC, using photodiode array (PDA) detection. The method provides exceptional chromatographic repeatability and affords LOQs well below the current concentration levels of interest for cannabinoids in edibles. Thereupon, the method/procedure defined herein can be expected to fulfill the essential task of ensuring product uniformity and cannabinoid screening in edible foods.
Following the 2018 legalization of recreational cannabis usage in Canada, the quality and safety of cannabis products has garnered significant attention. Health Canada has developed a regulatory program mandating pesticide testing on all cannabis products. Under the program, licensed producers (LPs) of cannabis products in Canada are required to send representative samples of products to independent laboratories for pesticide screening and quantification. In this application note, a robust and reliable method for the analysis of 96 pesticides in cannabis flower by LC/MS/MS utilizing both ESI and APCI modes is presented. The method not only offers ultra-low detection limits at or below the Health Canada regulatory levels, but also offers significant efficiency gains over other available methodologies. Utilizing LC/MS/MS with both ESI and APCI modes obviates the need to perform both GC/MS/MS and LC/MS/MS analyses to analyze all 96 regulated pesticides, saving significant time and money for operators.
The use of cannabis concentrates and CBD products (edibles, topicals, vape products, etc.) has increased in popularity as new regulation has been passed legalizing medicinal and recreational use in a number of states and provinces. Testing to ensure that pesticide and mycotoxin levels in cannabis products are below regulatory levels is critical, however, the cannabis concentrate matrix presents many analytical challenges including higher sample matrix effects and an increased concentration of cannabinoids in the sample. In this application note, an LC/MS/MS method for the analysis of 66 pesticides (including hydrophobic and chlorinated pesticides typically analyzed by GC/MS/MS) and five mycotoxins in a cannabis concentrate matrix is presented. Utilizing a QSight® 420 LC/MS/MS instrument with dual APCI and ESI sources, the analysis yielded excellent recoveries and detection limits below those specified by the state of California cannabis regulations.

This application describes the use of an RVA to assess the effect of added ingredients on the mashing behavior of a malt. Malts are tested with and without added enzymes, adjuncts or chemicals (e.g. pH modifiers). The differences are used to determine the improvement or deterioration in mashing behavior of the malt due to the addition.
This high temperature RVA method is applicable to any unmodifies and modified starches and their derivatives, including composites with hydrocolloids and lipids. High shear is used in the method to approximate typical processing conditions for these ingredients, which are commonly used as far replacers, gelling agents and stabilizers, and as paper wet end, size press and coating additives.
This method describes an accelerated procedure for testing semolina samples using the doughLAB. Using a faster mixing speed, results can be obtained quicker and more accurately. The method is applicable to flour that is very strong or is difficult to develop.
Formulations for breads, cakes and baked products usually include a combination of additives to improve dough stability, texture and organoleptic qualities. Some of the more common additives include reducing and oxidizing agents, salt, sugar, enzymes, and emulsifiers. The effects of these additives on dough quality can be examined on the doughLAB, by comparing a sample with and without the additive. A longer test profile is used to allow for the strengthening effect of some of the additives to be fully observed.
Raw starch pasting curves have a typical low initial (cold) viscosity, followed by a viscosity peak caused by swelling of the raw starch granules, and a relatively high setback viscosity. Processing by thermal and mechanical inputs will progressively reduce peak and setback viscosities. Cold viscosities will increase through a pre-gelatinization effect, and then eventually decrease through granule rupture and dextrinization, as the prior degree of cook increases. The RVA can therefore be used to assess how cooked a product is, with applications for system characterization, at-line process control, product development, scale-up, transfer, troubleshooting and assessment of competitive products.
Rice sensory quality is of prime importance throughout Asia where rice is a staple food. This RVA method, developed by The Food Agency in Japan, provides a longer profile than Method 10, to better discriminate between rice samples of similar quality.
The method is applicable to unmodified dent corn starches. The final temperature of 65°C (149°F) is used to rapidly stabilize viscosity and minimize retrogradation. Combining speed, precision, flexibility and automation, the RVA is a unique tool for product development, quality and process control and quality assurance.
Wheat flour quality can vary greatly between samples.

DA 7250 can determine all these characteristics in seconds.
Analysis of Total Solids of batter and coatings is an important process control measurement for potato processors. By accurately controlling solids, the producer can experience significant savings. Realizing these savings is dependent both upon the accuracy of the analyses and the availability of real-time results. Using the DA 7200, production staff can perform their own analysis 24/7 and have instant access to the results. The results can be used to ensure the proper solids are available to the potatoes, to reduce waste, and to avoid costly mistakes and potential penalties.
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.
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.
Mycotoxins are naturally occurring toxins produced by molds or fungi, most often developed due to extreme weather events. To help you detect mycotoxins and aflatoxins in grain and cereals, PerkinElmer has developed a wide range of test kits and strip tests able to perform key protective measures and ensure grains are free of harmful toxins before entering the food supply. A comprehensive brochure is available to give an overview of our best-in-class accessories that can provide you with the most reliable food safety tests and analysis.

Insect damage of wheat grains results in reduced flour quality, which leads to weak doughs, breads of low volume and poor texture. The insect injects its saliva into the grain and lay eggs that hatch and develop in vivo, often leaving no visible external damage. This method shows the use the RVA to rapidly differentiate sound and insect-damaged wheat samples.

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.

Malts are tested with and without added enzymes, adjuncts or chemicals (e.g. pH modifiers). The differences are used to determine the improvement or deterioration in mashing behavior of the malt due to the addition.
The profiles in this method are modified from the procedures of Broadhead et al. (2004), using malted barley and wheat.In studying barley malt and modified malt samples for distilling performance, Broadhead et al. (2004) used a 30-minute heating profile on the RVA to successfully identify malts.
This procedure is based on the method of Goode et al. (2005) using malted and unmalted barley, to study the effect of endogenous enzyme and added adjunct levels, respectively, on mash viscosity. This profile can be used to check the suitability of a batch of grain for mashing, or for checking the appropriate level of added adjunct in the mashing system.The RVA is used as a laboratory-scale rheological tool for the characterization of mash viscosity, allowing the brewer to monitor the processes that are taking place during mashing.
This method tempers the premixed dough to the temperature of the subsequent processing step, and rapidly measures the consistency of the dough. The method is applicable to high-water addition doughs (such as that used in bread production), and low-water addition, high-fat doughs (such as that used in biscuit/cookie production). The Premixed Dough method can be used to control the quality of the halfproduct.
The ability of the components of a product to withstand high-temperature processing conditions is of interest to formulators, who must balance the need for acceptable product rheology with safety and throughput. The Rapid Visco Analyser (RVA) can perform high temperature tests. The method presented in this document is applicable to any liquid or hydrated ground material including, but not limited to, unmodified starches, flours, whole meals, gums, diary ingredients, and other formulations.
This high-temperature RVA method is designed to mimimc retorting, allowing assessment of the suitabilitu and stability of polysaccharide thickeners (eg. Gums, modified starches) in the formulation for high temperature processing.
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.
Formulations for breads, cakes and baked products usually include a combination of additives to improve dough stability, texture and organoleptic qualities. Some of the more common additives include reducing and oxidizing agents, salt, sugar, enzymes, and emulsifiers. The effects of these additives on dough quality can be examined on the doughLAB, by comparing a sample with and without the additive.

Aflatoxin B1 is considered to be the most genotoxic of the mycotoxins, and, when ingested by cows, is converted to aflatoxin M1 which has been shown to cause liver cancer in certain animals.
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.
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.

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.
Trace elemental analysis of grains can provide associations between air pollution sources and soil variables. The elemental capabilities and dynamic range of inductively coupled plasma mass spectrometry (ICP-MS) make it ideally suited for the analysis of food materials. The ultratrace detection limits of ICP-MS permit the determination of low-level contaminants, such as Pb, As, Se, and Hg, while the macro-level nutritional elements, such as Ca, Mg, K, and Na, can be quantified usingthe extended dynamic range capability of ICP-MS which provides the ability to measure concentrations over nine orders of magnitude.

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.
An ELISA or Enzyme Linked Immuno-Sorbent Assay allows for the rapid screening and quantitation of analytes against a variety of materials. We offer a wide range of ELISA kits to measure the safety of dairy, meat, poultry, seafood, grain, feed, and honey. ELISAs involve at least one antibody with specificity for a particular analyte or antigen and consist of the following basic protocol: Liquid sample containing the target analyte is added to a microwell that is pre-coated with analyte-specific antibodies. Any target analyte in the sample binds to the antibodies. An enzyme-linked antibody or antigen is added to the microwell, also binding to the analyte specific antibodies coated to the microwell. A substrate is added which changes its color as it interacts with the enzymes linked to the analytes or antibodies. The color change is measured with a spectrophotometer. Quantitation of the analyte is determined by comparing the test sample results against a standard curve of known analyte concentrations.
