Managing the Rise of Food Fraud
With alarming frequency, consumers are buying products that do not match what is stated on the label.
One of the contributing factors is the Covid-19 pandemic which created opportunities for food fraudsters and shone a light on the need for transparency in our food system.
The Rise of Food Fraud since the Covid-19 Pandemic
Factors related to the pandemic have created conditions to make food fraud more pervasive:
- Supply Chain Disruptions: Disruptions in global supply chains, including transportation, logistics, labor shortages, and product shortages have caused many manufacturers to look for new sources of supply.
- Rising costs: Manufacturers have tried to manage product costs by sourcing cheaper ingredients.
- Regulatory challenges: Governments and industry worldwide focused on managing the public health crisis during the pandemic, sometimes leading to reduced oversight of food safety.
Food fraud occurs when food and supplement products are misrepresented, adulterated, or mislabeled for economic gain. This can mean intentional substitution, dilution, or misrepresentation of ingredients, misleading labeling, false certifications, or any other fraudulent activity related to food production, distribution, or sale.
- Dilution: Mixing a high-quality ingredient with a lower quality or lower value ingredient. For example, adding water to milk or substituting lower-grade oils in olive oil.
- Substitution: Replacing a component of a food product with an alternative, often cheaper, ingredient.
- False labeling: Misrepresenting the origin, quality, or authenticity of a food product. This includes incorrect geographic indications, counterfeit certifications, or misleading claims about ingredients or production methods.
- Counterfeit products: Producing and selling imitation or fake food products that mimic popular brands, often with inferior or unsafe ingredients.
- Grey market activities: Diverting food products intended for one market or purpose to another unauthorized market, often for financial gain. This can involve expired or substandard products being sold as fresh or high-quality.
Affected industries are making efforts to battle food fraud with several strategies. These include supply chain traceability systems, certification programs, and collaborative efforts with governments and industry groups to share information. Now manufacturers, suppliers and retailers are starting to implement more rigorous testing protocols, with tools that can provide the information needed to detect fraud.
Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique that can help in the detection and prevention of food fraud:
Getting Ahead of Food Fraud with NMR
- Authenticity Testing: NMR can be used to analyze the chemical composition of ingredients and finished products and compare them against known reference samples. By creating a unique fingerprint or profile of a specific food or ingredient, NMR can identify any discrepancies or adulteration. For example, NMR can detect the presence of cheaper or unauthorized ingredients in products such as olive oil, honey, or spices.
- Geographic Origin Verification: NMR can analyze the isotopic and chemical composition of food products to determine their geographic origin. Certain elements or compounds in foods exhibit characteristic isotopic ratios or chemical profiles that can be linked to specific regions.
- Detection of Adulteration: NMR can detect and quantify the presence of adulterants or fillers in food products by comparing the expected composition of a pure product with the actual composition measured. This is particularly relevant for high-value products like spices, oils, or fish where adulteration is common.
- Quality and Purity Assessment: NMR can assess the quality and purity of food ingredients by providing detailed information about their chemical composition: the concentration of active compounds, impurities or contaminants, and the overall quality and authenticity of the product. NMR analysis can be particularly useful for evaluating the quality of herbal supplements, botanical extracts, or natural flavors.
NMR is an untargeted, rapid, and reliable analytical tool. By leveraging the capabilities of NMR spectroscopy, food industry stakeholders, regulatory agencies, and quality control laboratories have a powerful weapon in the fight against food fraud.
