Food Composition and Analysis

Food composition and analysis involve the comprehensive characterization and quantification of nutrients, bioactive compounds, additives, contaminants, and other components present in food samples. This field of study provides essential information about the nutritional content, chemical composition, and safety profile of food products, contributing to dietary assessment, regulatory compliance, food labeling, and quality control. Analytical techniques such as proximate analysis, elemental analysis, chromatography (such as gas chromatography and liquid chromatography), spectroscopy (including infrared, ultraviolet-visible, and nuclear magnetic resonance spectroscopy), mass spectrometry, immunoassays, and molecular techniques (such as polymerase chain reaction) are commonly used to analyze food samples. Food composition analysis involves determining the concentrations of macronutrients (such as carbohydrates, proteins, fats), micronutrients (such as vitamins and minerals), dietary fiber, water content, and energy content in food products. This information is crucial for assessing the nutritional adequacy of diets, formulating dietary guidelines, and informing consumers about the nutrient content of foods through nutritional labeling.
