Principles of Food Analysis

Primary Focus of Food Analysis

• Determining the composition, quality, and safety of food products.
• Investigating nutritional content, including vitamins, minerals, and macronutrients.
• Assessing the presence of contaminants, toxins, or adulterants in food items.

Common Analytical Techniques in Food Analysis

• Spectroscopy (e.g., UV-Vis, IR) for identifying compounds based on light absorption or emission.
• Chromatography (e.g., HPLC, GC) for separating and analyzing components in food matrices.
• Mass spectrometry for precise identification of molecular structures and masses.
• Microbiological methods for detecting and quantifying microorganisms in food.

Importance of Food Analysis in the Food Industry

• Ensures compliance with food safety regulations and standards.
• Enhances product quality and consistency to meet consumer expectations.
• Aids in product development and innovation by characterizing new ingredients.
• Supports proper labeling and nutritional claims to inform consumers.

Main Purpose of Nutritional Analysis of Food

• Provides essential information for dietary planning and nutritional guidance.
• Helps identify deficiencies or excesses of specific nutrients in populations.
• Supports health claims and dietary recommendations established by health authorities.
• Informs regulatory compliance for nutritional labeling on packaged foods.
