Lecture notes covering food composition, nutritional needs, digestion, processing, spoilage, quality standards, and food safety as per ICAR 6th Deans' Committee 2026. Course Code: ELEC 20 | Credits: 4(3+1).
Nutrition focuses on what the body needs and how nutrients affect health, while food science focuses on the nature of foods, their composition, processing, spoilage, storage, quality, and safety. The two overlap, but they are not the same discipline.
This elective usually covers food composition, nutrient requirements, digestion and metabolism, malnutrition, food processing, nutrient changes during processing, spoilage, food microbiology, quality standards, food laws, food safety systems, and fortification.
Because the nutritional value of food is not determined only by composition on paper. Processing, storage, additives, and preservation can change nutrient retention, shelf life, digestibility, and safety.
Food spoilage refers to deterioration in quality, acceptability, or safety due to microbes, enzymes, oxidation, moisture, temperature, or storage problems. It is important because food value depends on stability and safety, not just nutrient content.
HACCP stands for Hazard Analysis and Critical Control Points. It is a systematic food-safety approach that identifies where risks can occur in the food chain and helps control them before the final product reaches the consumer.
They are important because food from agriculture eventually enters regulated markets. Students need to understand how standards, labeling, quality requirements, and safety rules affect processing, sale, and public trust.
Food fortification means adding essential micronutrients to food to help reduce deficiency risks in the population. It is discussed because the course connects agriculture and food systems with public nutrition outcomes.
A strong approach is to connect every nutrition concept with a food-quality or food-safety angle. For example, learn not just nutrients, but also what processing, spoilage, standards, and fortification do to their real value in practice.
Because agricultural value continues after harvest. Students who understand nutrient quality, processing behavior, spoilage, standards, and safety can better connect farm production with consumer health and market usefulness.
