Study Notes
Food Loss & Waste
- 14% of food is lost before reaching consumers, and 17% is wasted annually.
- Ineffective cold chains are a major cause.
- Perishable food needs controlled temperature throughout production, storage, processing, marketing, and distribution.
- Cooling technologies consume a significant amount of electricity, often from fossil fuels.
- Ozone-depleting substances (ODS) and hydrofluorocarbons (HFCs) are powerful greenhouse gases.
- Cold chains contribute about 4% of global GHG emissions, impacting climate change and food production.
- Lack of access to cold chains affects food security, livelihoods, and market access.
Improving Food Cold Chains
- The Montreal Protocol (1987) aims to protect the ozone layer by phasing out ODS in cooling technologies.
- Phasing down HFCs addresses energy efficiency.
- Sustainable food cold chains support the SDGs and benefit farmers, fishers, and communities.
- Better access to nutritious foods is a key goal.
Temperature Control
- Temperature control minimizes bacterial multiplication and reduces food spoilage risk.
- Keeping food outside safe temperature zones increases spoilage risk.
- The "cold chain" is a key principle in temperature control.
Food that Doesn't Need Temperature Control
- Some foods, like raw, whole fruits and vegetables, can be stored at room temperature (about 20°C) to maintain quality.
- Storing them properly prevents spoilage and maximizes shelf life.
Frozen Foods
- Frozen foods must be kept below -18°C, both during storage and transport.
- Maintaining this temperature is crucial for quality.
- Different food types should be stored separately (dairy, meat, poultry, and fish).
Measuring Food Temperatures
- Core temperature (middle of the food) should be measured, as the outside might be different.
- A sensitive thermometer or probe is necessary for accurate measurements.
- Cleaning and disinfection of the thermometer before use is essential to avoid contamination.
Blast Freezing
- A process that quickly reduces food temperature.
- High-velocity cold air lowers the temperature rapidly, reducing ice crystal size and maintaining food quality.
- Helps protect nutrients and flavor in foods like chicken.
- Important for preserving texture and flavor
Food Packaging Technologies
- Packaging keeps food safe and increases its shelf life.
- Various packaging materials exist: paper/paperboard, plastic, glass, and metal.
- Each material has advantages and disadvantages in terms of cost, properties, and environmental impact.
Edible Packaging
- Innovative packaging created using edible materials.
- Examples include containers for pumpkin soup, spinach membrane, lemon juice in lemon membrane, and melting chocolate in cherry membrane.
Micro-Packaging
- A nanotechnology-based material that is 70% water and clay.
- It's a thin film-like substance, offering preservation capabilities compared to other food packaging options.
Intelligent Packaging
- Innovative packaging for food.
- The packaging has sensors that determine whether the food is contaminated.
- Designed to preserve the viability of food more effectively.
Antimicrobial Packaging
- Packaging that inhibits the growth and spread of bacteria, beyond just preventing bacteria from contacting the food.
- This type of antimicrobial protection offers a long shelf-life for food.
Food Preservation
- Methods for storing food for prolonged periods, preventing spoilage.
- Includes traditional (e.g., smoking, salting, drying, and low-temperature storage) and modern methods (e.g., canning, freezing).
- Each method addresses issues like bacterial, pest, and fungal contamination to ensure food safety.
Milk Preservation
- Pasteurization is a critical step in milk preservation to achieve safety standards.
- Temperature and time parameters are essential in the process.
- Milk powder preservation is beneficial for storage.
- Proper packaging is essential to maintain quality and safety during storage.
Fish Preservation
- Methods for Fish Preservation include drying, salting, and smoking to maintain freshness and inhibit bacterial growth.
- Different sizes and preparation methods for fish are used for preservation.
