Study Notes
Course Overview
- Emphasis on chemical food analysis for qualitative and quantitative assessments of food components.
- Major components analyzed include moisture, protein, carbohydrates, lipids, minerals, and vitamins.
- Hands-on experiments are integral for learning chemical analysis methods.
Objectives
- Understand analytical techniques' principles.
- Analyze and evaluate food product compositions.
- Select appropriate analytical techniques for practical problems.
- Demonstrate proficiency in food analysis laboratory settings.
Required Texts
- Food Analysis, 4th Edition by S. Suzanne Nielsen, 2010.
- Food Analysis: Theory and Practice, 3rd Edition by Pomeranz Y & Meloan C.E., 1994.
- Modern Methods of Food Analysis, 1st Edition by Stewart, K.K. and Whitaker, J.R., 1984.
- Pearson’s Composition and Analysis of Foods, 9th Edition by Kirk, R.S. and Sawyer, R., 1991.

Importance of Food Analysis
- Compliance with government regulations ensures safe and wholesome food for consumers.
- Provides nutritional information, enabling informed dietary choices.
- Promotes fair competition among food manufacturers.
- Helps eliminate economic fraud in the food industry.
Government Regulations
- Standards: Agencies specify voluntary and mandatory composition, quality, inspection, and labeling standards for food products.
- Nutritional Labelling: Includes nutritional details such as calorific value, fats, cholesterol, sodium, carbohydrates, sugars, protein, vitamins, calcium, and iron. Claims like "low fat" and "high fiber" are regulated.
- Authenticity: The market price of certain foods is influenced by ingredient quality.
- Food Inspection and Grading: Regular analyses ensure food products comply with laws and regulations.
Food Safety
- Concerns the safety of consumers and manufacturers.
- Foods can be unsafe due to harmful microorganisms (e.g., Listeria, Salmonella), toxic chemicals (e.g., pesticides), or extraneous matter (e.g., glass, wood).
- Mandatory for manufacturers to guarantee products are free of these hazards.
Quality Control
- Ensures consistency and uniformity in product quality.
- Monitors safety and specific ingredient specifications.
Research and Development
- Focus on developing new food products and enhancing existing ones.
- Aims to understand the functional properties of various ingredients.
