Study Notes
Importance of Food Packaging
- Food packaging is used to protect food from damage and contamination, hold contents, preserve and extend shelf life, and reduce food waste.
- It also makes food easier to handle, transport, and serve, while improving hygiene and food safety.
- Packaging can make food more attractive and provide information on contents, storage, and use.
Determining Factors for Packaging
- Many factors determine the type of packaging used, including food hygiene and safety considerations.
- The material must be suitable for the food, as some chemicals present in the food or packaging may react together.
Types of Packaging Materials
- Paper and card: commonly used for breakfast cereals, flour, and wrapping food items like sandwiches.
- Glass: often used for sauces, pickled foods, oils, and drinks, with a long shelf life, but prone to breaking.
- Metal: used for soup, fruit, and vegetables, with heat-treated cans to prevent infection, but liable to denting.
- Modified Atmosphere Packaging (MAP): suitable for specific food types.
- Plastic/polystyrene: used for various food items, but can be environmentally damaging.
Environmental Impact of Packaging
- Producing packaging uses up natural resources like trees, oil, and energy.
- Packaging can be environmentally damaging due to the materials and processes used.
- Non-biodegradable packaging can take years to break down, and recyclable packaging may not always be possible.
Reducing Packaging Waste
- Consumers: recycle, repurpose containers, avoid non-biodegradable packaging, use reusable bags, and buy from retailers with minimal packaging.
- Retailers: sell loose items, use brown bags or mesh bags, sell food in recyclable containers, and offer refill stations.
Key Points
- Packaging serves multiple purposes, including protection, preservation, and presentation.
- There are various types of packaging materials, each with its advantages and disadvantages.
- The environmental impact of packaging is significant, and reducing waste requires concerted efforts from consumers, retailers, and manufacturers.
