Study Notes
Introduction to Food Science
- Food science is a multidisciplinary field studying the physical, chemical, and biological properties of food.
- It focuses on food production, processing, storage, and consumption.
- It encompasses food safety, nutrition, preservation, and quality.
- Food scientists use scientific principles to improve food quality, safety, and nutritional value.
- Food science addresses consumer needs, preferences, and societal issues surrounding food.
Food Composition
- Foods are complex mixtures of various chemical substances.
- Key components include carbohydrates, proteins, lipids, vitamins, minerals, and water.
- Carbohydrates (sugars, starches, fibers) provide energy.
- Proteins (building blocks) form tissues and enzymes.
- Lipids (energy storage, insulation) regulate hormones.
- Vitamins and minerals are essential for bodily functions.
- Water is crucial for biological processes and nutrient transport.
Food Processing
- Food processing alters raw food attributes physically, chemically, and biologically.
- Techniques include freezing, canning, drying, fermentation, and irradiation.
- Processing enhances safety, preservation, palatability, texture, nutritional content, and convenience.
- Processing methods depend on desired final product characteristics.
Food Safety
- Food safety is crucial for preventing foodborne illnesses.
- It involves managing factors causing contamination and spoilage.
- Microbial contamination (bacteria, viruses, parasites) is a significant concern.
- Temperature control, hygiene practices, and proper handling prevent illness.
- Home food safety practices (preparation, storage, reheating) are vital.
Food Quality
- Food quality encompasses sensory attributes (color, flavor, texture, aroma), nutritional value, safety, and content.
- Consumer perceptions of food quality influence purchasing decisions.
- Objective and subjective metrics, using expert panels and consumer feedback, assess quality.
Food Preservation
- Food preservation extends product shelf life.
- It prevents spoilage, microbial growth, and enzymatic reactions.
- Techniques include refrigeration, freezing, canning, drying, and irradiation.
- Preservation methods affect nutritional value, texture, and sensory characteristics.
Food Packaging
- Food packaging protects food from oxygen, light, and moisture.
- It increases shelf life.
- Packaging materials (plastics, paper, metals) are important.
- Functional packaging (temperature-sensitive inks, active components) enhances food protection.
Food Microbiology
- Food microbiology studies food microorganisms, their growth, survival, effects on quality and safety.
- Bacteria, fungi, yeasts, and molds may cause spoilage or illness.
- Understanding microbial behavior helps design preservation methods.
Nutritional Aspects of Food
- Nutrition is an integral part of food science.
- Food scientists investigate food nutritional value and its health effects.
- They develop dietary recommendations and guidelines based on research.
- Research links diet, nutrition, and health outcomes.
Consumer Behavior
- Consumer food consumption behavior is frequently studied.
- Taste preferences, cultural influences, and economic factors affect choices.
- Understanding consumer behavior assists in developing effective marketing strategies.
