Spectroscopy for food safety

Spectroscopy is an analytical technique that uses the interaction between matter and electromagnetic radiation to study the properties of matter. In food safety, spectroscopy is used to identify and quantify chemical compounds in food and detect any contaminants or adulterants that may pose a risk to human health.


Some common spectroscopic techniques used in food safety include:
 

  1. Infrared (IR) spectroscopy: IR spectroscopy can identify and quantify the chemical bonds in food samples. It is commonly used to detect the presence of contaminants, such as pesticides, in food.
  2. Ultraviolet-visible (UV-Vis) spectroscopy: UV-Vis spectroscopy can be used to detect and quantify the presence of specific chemicals in food, such as mycotoxins and other contaminants.
  3. Mass spectrometry (MS): MS is a powerful analytical technique that can be used to identify and quantify the individual components of complex mixtures in food samples, such as proteins, lipids, and carbohydrates.
  4. Nuclear magnetic resonance (NMR) spectroscopy: NMR spectroscopy is used to study the chemical structure and properties of molecules in food. It can be used to detect the presence of contaminants, such as heavy metals, in food.

 

Spectroscopy is a useful tool for food safety and quality control, as it can be used to identify and quantify the chemical composition of food products. Here are some examples of how spectroscopy is used in food safety:

 

Soybean

Spectroscopy for soybean analysis

Spectroscopy techniques, such as near-infrared (NIR) spectroscopy, can be used to analyze soybean samples for protein and oil content. This information can help farmers and processors determine the quality of their soybeans, and ensure that they meet the necessary standards for use in food products.

Barley

Analyzing constituents in barley

Spectroscopy can also be used to analyze the chemical composition of barley, which is used in the production of beer and other alcoholic beverages. For example, Fourier transform infrared (FTIR) spectroscopy can be used to detect and quantify mycotoxins in barley, which are harmful substances produced by certain types of fungi.

Hemp

Monitoring for hemp production

Hemp is a crop that is gaining popularity for its use in food products, such as hemp oil and hemp protein powder. Spectroscopy techniques, such as Raman spectroscopy, can be used to analyze the chemical composition of hemp samples and detect any contaminants or adulterants that may be present.

Adulteration and counterfeiting of global foods

Adulteration and counterfeiting of global foods

Spectroscopy can be used to detect adulteration and counterfeiting in a wide range of food products. For example, NIR spectroscopy can be used to identify counterfeit olive oil by analyzing its fatty acid composition. Similarly, FTIR spectroscopy can be used to detect adulterants in honey, such as corn syrup or rice syrup.
