Key Takeaways:
- Shelf life is how long a product stays good, while expiration dates are when it's best to eat. Preservatives, storage, and packaging all affect how long food lasts.
- Some foods and non-food items can last a really long time if stored properly. Factors like temperature, humidity, and sealing affect how long things stay good.
What is Shelf Life?
Shelf life refers to the length of time a product remains usable, fit for consumption, or saleable. Understanding shelf life is crucial for food safety, reducing waste, and saving money.
- Shelf life is the period during which a product can be stored without becoming unfit for use or consumption.
- Expiration dates are not the same as shelf life. Expiration dates indicate the last date a product should be consumed, while shelf life is about maintaining quality.
- Preservatives play a significant role in extending the shelf life of many products, especially food items.
- Storage conditions such as temperature, humidity, and light exposure can greatly affect the shelf life of products.
- Packaging innovations like vacuum sealing and modified atmosphere packaging help extend the shelf life of perishable items.

Factors Affecting Shelf Life
Several factors influence how long a product can last. Understanding these can help in extending the shelf life of various items.
- Temperature: Higher temperatures can accelerate spoilage, while cooler temperatures can extend shelf life.
- Humidity: Moisture can lead to mold and spoilage, so keeping items dry is crucial.
- Light: Exposure to light can degrade certain products, especially oils and vitamins.
- Oxygen: Oxygen can cause oxidation, leading to spoilage. Vacuum sealing can help mitigate this.

Tips for Extending Shelf Life
Simple practices can help you get the most out of your stored items.
- Rotate stock: Use the oldest items first to ensure nothing goes to waste.
