Packaging And Labelling Flashcards
What is one function of packaging?
Protects the food from contamination during transport and storage.
Example: Chicken is wrapped in plastic packaging and can be vacuum packed to prevent entry of salmonella.
How does packaging make transportation easier?
Packaging makes it easier to transport food items.
Example: Milk has a handle to allow easy carrying.
What does packaging do to prevent oxidation?
Packaging can keep air out, preventing oxidation that causes bad smells and tastes.
Example: Salmon can develop a bad smell if oxidized.
How does packaging increase shelf life?
Packaging prevents waste and spoilage by keeping microbes out.
Example: Meat is wrapped in plastic to prevent microbial entry.
What information does packaging provide?
Packaging provides essential information such as expiry dates and ingredients.
Example: If allergic to nuts, one can check the ingredients before buying a product.
What is a desirable property of good packaging?
It should be easy to open and reseal to keep microorganisms out.
This helps prevent spoilage of food.
What are the environmental benefits of biodegradable and recyclable packaging?
They break down naturally and do not harm sea life.
Example: Paper is biodegradable.
What is recycling?
The process of turning used waste materials into new products, reducing waste and saving energy.
What are some types of packaging?
Metal, Glass, Paper, Plastic.
What are two types of metal packaging?
Tin cans and Aluminium cans.
Example: Beans are often in tin cans, while coke is in aluminium cans.
What is an advantage of metal packaging?
It is coated with plastic to prevent food from reacting with the metal.
What is a disadvantage of metal packaging?
If dropped, a dent may occur, allowing air in and causing oxidative rancidity.
What is the environmental impact of metal packaging?
Metal packaging is non-biodegradable but can be recycled, reducing waste.
What are two types of glass packaging?
Jars and Bottles.
Example: Jam is often in jars, while milk is in bottles.
What is an advantage of glass packaging?
It protects food from contamination as no microorganisms can enter.
What is a disadvantage of glass packaging?
Glass is heavy, leading to high transport costs and can easily break.
What is the environmental impact of glass packaging?
Glass can be reused and recycled, reducing energy consumption.
What are two types of paper packaging?
Plain paper and Cardboard.
Example: Sugar is often packaged in plain paper, while cereal boxes are made of cardboard.
What is an advantage of paper packaging?
It is lightweight, contributing to low transport costs.
What is a disadvantage of paper packaging?
It is not durable and can disintegrate when wet.
What is the environmental impact of paper packaging?
Paper packaging is biodegradable and recyclable.
What are two types of plastic packaging?
Plastic cartons and Polythene bags.
Example: Yogurt is often in plastic cartons, while pasta is in polythene bags.
What is an advantage of plastic packaging?
Plastic is strong and protects food from contamination.
What is a disadvantage of plastic packaging?
Plastic is non-biodegradable and can melt when in contact with acid.
