Ethylene oxide (EO) is a colorless gas widely used to preserve dry food. Residues of EO and its degradation products need to be monitored since their consumption negatively impacts human health. Ethylene oxide poses challenges for analysts as a small and highly volatile molecule. This means that special precautions must be taken during sample preparation to avoid analyte losses through evaporation. A comprehensive workflow from sample extraction to highly sensitive GC-MS/MS analysis is presented, meeting regulatory compliance according to the SANTE validation criteria for pesticides residues in food and feed.

In this case study, you’ll discover:

• The utility of the Thermo Scientific TRACE 1610 GC system and the Thermo Scientific TSQ 9610 triple quadrupole
  GC-MS/MS for the analysis of ethylene oxide and 2-chloroethanol residues in food samples.
• A comprehensive workflow from sample extraction to highly sensitive GC-MS/MS analysis.
• Regulatory compliance according to the SANTE validation criteria for pesticides residues in food and feed.
• The robustness of the system to provide stable results during a 3-day unattended sequence.

Virgin and extra virgin olive oils are sometimes adulterated with cheaper vegetable oils and lower-grade olive oils due to the high demand and price of high-grade olive oil. Not only is it important to authenticate olive oil to prevent fraud, it is also necessary to determine purity for the health and safety of consumers.

Read this case study to discover a simple way to tackle the adulteration of extra virgin olive oil. You’ll learn:

• Why there is research on olive oil adulteration;
• The mission of the first center in North America dedicated to olive oil research;
• How to authenticate olive oil quicker and easier; and
• The future of olive oil production.

The key to great winemaking lies in knowing how to create distinctive styles of wine that are perceptible for their color, taste, and smell. These attributes stem from complex chemical reactions that occur throughout the process, and any imbalances in these interactions can alter the quality of the final product.

Wiley has partnered with Thermo Fisher Scientific to bring together a special collection of articles that detail just how to monitor and control the chemical reactions that occur during winemaking—from vine to glass.

This important compendium features content from Thermo Fisher Scientific and Wiley publications, including Food Quality & Safety. You’ll read about:

• How to extend shelf life.
• The sources of volatile sulfur compounds.
• The effect of wine closers on certain compounds.
• How carbon dioxide can impact the sensory properties of wine.
• Automatic titration.
• Oxygen content.
• Measuring pH and clarity.

By providing resources that detail analytical testing in winemaking, we hope to empower you with the knowledge to provide your customers with an extraordinary glass of wine.

Global concern over food and environmental pollutants is driving the demand for more rapid and reliable methods for the identification and quantitation of chemical residues in matrices such as food and water. Analyzing pesticide residues in food is a critical step in ensuring a safe food supply, as these contaminants can negatively affect human health. However, screening for these pollutants requires high sensitivity to meet the strict regulatory requirements for maximum residue levels.

Wiley has partnered with Agilent Technologies to bring together a special collection of articles that detail how high resolution mass spectrometry and gas chromatography can be used to screen for pesticides and other contaminants in food and in the environment. This important compendium features content from Agilent Technologies and Wiley publications, including Food Quality & Safety.

In this collection, you’ll read about:

• Trace pesticide residue analysis in complex matrices.
• Multiresidue pesticide evaluation in salmon.
• Determining pesticides and residue distribution in strawberries.
• Assessing multiple pesticide residues in tea.
• Analyzing wastewater effluent samples to screen for toxic chemicals.
• Evaluating the occurrence and distribution of emerging pollutants in water.

By providing resources detailing how to detect pesticides in food and in the environment, we hope to empower readers with the knowledge to provide their customers with a safe, quality product.

Many U.S. states and Canada have legalized medicinal and recreational marijuana, which has increased consumer demand for cannabis and cannabis-infused products. With respect to regulations in the U.S., there is little harmonization between the federal and state governments. Therefore, it has been left to the states, which has created a disparate mosaic of laws across the nation.

To meet regulatory requirements, cannabis and hemp products require numerous safety tests. Among the necessary tests for these products is the analysis of heavy metals, such as arsenic, cadmium, mercury, and lead.

Wiley has partnered with Agilent Technologies to bring together a special collection of articles detailing testing methods for determining heavy metals in cannabis and hemp products. This important resource features articles from Agilent Technologies and Wiley publications, including Food Quality & Safety.

In this collection, you’ll read about:

• Testing methods to ensure the safety of cannabis-infused foods and beverages.
• The potential of hemp for paired phytoremediation and bioenergy production.
• The challenges of cannabinoid potency testing.
• The current potency trends for THC and other cannabinoids in cannabis.
• Heavy metals testing method using ICP-MS, approved by AOAC.
• Determination of heavy metals in cannabis and hemp products following the AOAC method for ICP-MS.

We think this series of essential articles will help you produce high-quality and safe products that meet consumer expectations.
