  • 2. Give at least 3 reason why knowing to use the appropriate type of packaging is important in this time of crisis.
  • 4. +Packaging need not only to be attractive nor presentable, instead it should be safe and should pass all the necessary appropriate standards in packaging as well.
  • 5. FOOD PACKAGING + Food packaging - is packaging of food which requires protection, tampering resistance, and special physical, chemical, or biological needs. + It also shows in the product label any nutrition information on the food being consumed.
  • 6. The main objective of packaging +is to keep the food in good condition until it is sold and consumed, and to encourage customers to purchase the product.
  • 7. +Packaging should provide the correct environmental conditions for food starting from the time food is packed through to its consumption.
  • 8. A good package should therefore perform the following functions: +Provide a barrier against dirt and other contaminants thus keeping the product clean +Prevent losses. For example, packages should be securely closed to prevent leakage
  • 9. +Protect food against physical and chemical damage. For example the harmful effects of air, light, insects, and rodents. Each product will have its own needs +Package design should provide protection and convenience in handling and transport during distribution and marketing
  • 10. Types of Packaging Materials + In many developing countries the most commonly used food packaging materials include: +leaves +vegetable fibers +wood +papers,newsprint +earthenware +glass +plastics +metals
  • 11. Leaves + Banana leaves are often used for wrapping certain types of food (e.g. suman). + They do not however protect the food against moisture, oxygen, odors or micro- organisms, and therefore, not suitable for long-term storage.
  • 12. Vegetable fibers + These include bamboo, banana, coconut, and cotton fibres. + These natural materials are converted into yarn, string or cord which will form the packaging material. + vegetable fibres do not provide protection to food which has a long shelf-life since they offer no protection against moisture pick-up, micro- organisms, or insects and rodents.
  • 13. Wood + Wood offers good protection, good stacking characteristics and strength. + The use of wood continues for some wines and spirits because the transfer of flavor compounds from the wooden barrels improves the quality of the product.
  • 14. Paper + Paper is an inexpensive packaging material. It is however highly absorptive, fairly easily torn, and offers no barrier to water or gases. + The degree of paper re-use will depend on its former use, and therefore paper that is dirty or stained should be rejected.
  • 15. Earthenware + Earthenware pots are used worldwide for storing liquids and solid foods such as curd, yoghurt, beer, dried food, and honey.
  • 16. Glass + Glass has many properties which make it a popular choice as a packaging material: + Glass is able to withstand heat treatments such as pasteurization and sterilization. + Does not react with food.
  • 17. Glass + Protects the food from crushing and bruising + Resistant to moisture, gases, odors and microorganisms + Re-usable, re-sealable and recyclable + Transparent, allowing products to be displayed.
  • 18. Disadvantages of using glass as packaging materials + Glass is heavier than many other packaging materials and this may lead to higher transport costs + It is easy to fracture, scratch and break if heated or cooled too quickly + Potentially serious hazards may arise from glass cracks or fragments in the food.
  • 19. Preparation of glass containers +Inspection +Washing. +Rinsing. +Sterilization. +Sealing and +capping +Cooling
  • 20. Plastics + The use of various plastics for containing and wrapping food depends on what is available. + Plastics are extremely useful as they can be made in either soft or hard forms, as sheets or containers, and with different thickness, light resistance, and flexibility.
  • 21. Flexible films are the most common form of plastic. Generally, flexible films have the following properties: + Cost is relatively low. + Good barrier properties against moisture and gases. + Heat sealable to prevent leakage of contents. + Have wet and dry strength.
  • 22. Flexible films are the most common form of plastic. Generally, flexible films have the following properties: +Easy to handle and convenient for the manufacturer, retailer, and consumer. +Weight is lighter than the product. +Fit closely to the shape of the product, thereby wasting little space during storage and distribution.
  • 23. Metal + Metal cans have a number of advantages over other types of containers. + Metal cans provide total protection of the contents. + Metal cans are tamperproof. + Metal cans are convenient for presentation.
  • 24. Disadvantages of metal food packaging materials: +Heavier than other materials, except glass, and therefore have higher transport costs +The heat treatment associated with the use of metal cans is not suitable for small-scale production
  • 25. Activity I: Choose Me Direction: Choose your answer from the words that you can found inside the box.
  • 26. + _______________1. Sample of this type of packaging are boxes and newsprint. + _______________2. Tin can are well known sample of this type of packaging. + _______________3. Sample of this type of packaging have traditionally been used for a wide range of solid and liquid foods including fruits, vegetables, tea and beer. + ______________4. We usually use this type of packaging to suman. + ______________5. This type of packaging does not react with food and protects it from crushing and bruising.
  • 27. +During this time of pandemic, It is very important to know the appropriate type of packaging you should use in your food product. +Give at least three reason why knowing to use the appropriate type of packaging is important in this time of crisis.
  • 28. TRUE/FALSE + _____1. Plastics are extremely useful as they can be made in either soft or hard forms, as sheets or containers, and with different thickness, light resistance, and flexibility. + _____2. Paper is the most expensive packaging material.
  • 29. +_____3. Glass is able to withstand heat treatments such as pasteurization and sterilization. +_____4. Vegetable fibers protects the food from moisture. + _____5. Leaves are suitable for long term storage.
