3 Types of Elderberry Adulteration and How to Detect Them 

Elderberry has gained significant attention recently due to its immune-boosting health benefits. This powerful plant, belonging to the genus Sambucus and native to Europe, has been the subject of numerous scientific studies that have found it to be effective in reducing the severity and duration of viral infections. 

While the demand for elderberry continues to grow, the problem of adulteration has become a significant concern for brand owners and ingredient suppliers alike. Adulteration refers to the addition of lower-quality or artificial ingredients to elderberry products. This can potentially harm consumers seeking the health benefits associated with elderberry. 

The high demand for elderberry has led to a supply shortage in some regions. This has resulted in using cheaper alternatives, such as black mulberry or black currant, to create elderberry products. 

The problem of adulteration not only affects the credibility of the suppliers but also poses a significant risk to consumers who may unknowingly consume products that contain harmful substances or lack the expected health benefits. This can also negatively impact the reputation of suppliers and brand owners who prioritize the quality and authenticity of their products. 

In this blog, we will delve deeper into the issue of elderberry adulteration, discussing the extent of the problem and its impact on the industry. We will discuss the current state of Elderberry adulteration and how brand owners and ingredient suppliers can ensure the authenticity of their products through Nuclear Magnetic Resonance (NMR). So, if you want to learn more about this important issue, read on! 

The State of Elderberry Adulteration 

Elderberry adulteration is a widespread issue in the industry that has become increasingly concerning in recent years. The current state of adulteration involves the addition of lower-quality or artificial ingredients to elderberry products, such as juices, syrups, and extracts. 

There are several different forms of elderberry adulteration, including: 

  • The use of cheaper substitutes, such as black mulberry and black currant, which lack the same health benefits as authentic elderberries.
  • The dilution of elderberry extracts with other substances, such as water, to reduce costs which can compromise the product's potency, safety, and quality. 

  • Adding artificial flavours and colours to elderberry products can mask the lack of authentic elderberry content. 

Elderberry adulteration can significantly impact the reputation and revenue of brands prioritizing their products' quality and authenticity. When consumers discover that a brand has been selling adulterated elderberry products, their trust and confidence in the brand can be severely undermined. This decline in trust can significantly impact a brand's reputation. Consumers who no longer trust a brand may switch to competitors or stop purchasing elderberry products altogether, resulting in a decline in sales and revenue and a loss of market share. 

On the other hand, a brand known for producing high-quality and authentic elderberry products can earn a positive reputation and increase brand loyalty. To take it a step further, a brand that is taking the necessary steps to ensure the purity and authenticity of their elderberry products will be eligible for third-party certifications, providing them with a competitive advantage that can be marketed to consumers. 

The Role of Nuclear Magnetic Resonance (NMR) in Detecting Elderberry Adulteration

There are several testing methods currently used to detect adulteration in elderberry products. However, each method has its limitations and may only be effective in detecting some types of adulteration. 

The following are the most commonly used testing methods for detecting elderberry adulteration: 

  • DNA Testing: DNA testing is targeted and can detect the presence of black currant and black mulberry DNA in elderberry products. While this method can accurately identify the presence of these substitutes, it may require more work to detect the addition of other cheaper substitutes.  
  • HPLC: High-performance liquid chromatography (HPLC) measures the levels of specific compounds in elderberry extracts. This method could identify dilution and substitution with other berry extracts but may not be able to detect all kinds of adulterants. 

  • Spectrophotometry: Spectrophotometry is a method that measures the absorbance of light by a substance to determine its concentration. It can detect the presence of elderberry anthocyanins, which are specific pigments found in elderberry. However, this method cannot detect the presence of cheaper substitutes or dilution with other ingredients. 

Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most accurate and reliable methods for detecting adulteration in elderberry products. NMR can identify the presence and concentration of specific molecules in a sample, providing detailed information on the product's composition. 

NMR works by placing a sample in a strong magnetic field, which causes the nuclei of the atoms in the sample to align. A pulse of radiofrequency energy is then applied to the sample, causing the nuclei to resonate and emit a signal that can be detected and analyzed. This signal provides information about the sample's chemical composition, allowing spectroscopists to identify the presence of specific molecules and the concentration of each component. 

One of the main advantages of NMR is its ability to identify a wide range of molecules and compounds, including complex mixtures. This makes it a highly effective method for detecting the addition of cheaper substitutes or other adulterants and the dilution of elderberry extracts. In addition, NMR can be used to verify the authenticity of elderberry extracts by identifying specific markers unique to elderberry. 

NMR is the best option for detecting adulteration in elderberry products due to its accuracy, reliability, and ability to detect a wide range of molecules and compounds. Its ability to provide detailed information on the composition of a sample makes it an essential tool for brand owners and ingredient suppliers who prioritize the quality and authenticity of their products.
