Chemical Analysis
Chemical analysis is the backbone of food ingredient analysis, employing various techniques to identify and quantify the chemical components of food. Chromatography, a powerful separation technique, is widely used. Gas chromatography (GC) is ideal for analyzing volatile compounds, such as fats, aromas, and pesticide residues. High-performance liquid chromatography (HPLC) is used for non-volatile compounds like sugars, vitamins, and additives. Chromatography works by separating components based on their physical and chemical properties, allowing for individual identification and quantification. Spectroscopy utilizes the interaction of light with matter to identify and measure substances. Ultraviolet-Visible (UV-Vis) spectroscopy measures the absorption of UV and visible light, providing information about the concentration of certain compounds. Infrared (IR) spectroscopy analyzes the vibrational modes of molecules, enabling the identification of functional groups and overall composition. Mass spectrometry (MS) measures the mass-to-charge ratio of ions, providing detailed structural information about molecules. These techniques are often coupled with chromatography (GC-MS, LC-MS) for enhanced separation and identification. Titration, a classic chemical analysis technique, is used to determine the concentration of a substance by reacting it with a known concentration of another substance. Titration is commonly used to measure acidity, alkalinity, salt content, and other parameters.
