Food preservation tips

Food preservation is all the rage these days. Many of us have become conscious of food waste both in terms of the environmental impact it causes and the hit to our own wallets from buying food that’s just going to get thrown away. Luckily there are lots of different ways of preserving food and making it last that little bit longer. In this article, we go through some key foods and learn how to extend their shelf life with some handy food preservation tips.

If in doubt, check whether food should be stored in or out of the fridge as the temperature can make a big difference to how long they last. Also, make sure you keep your fridge clean with the help of an effective cleaner like Handy Andy!

How to keep bananas fresh

Bananas make a tasty and nutritious snack, but they’re not so nice when they turn brown and over-ripe. Here are a few ways to keep them fresher for longer:

  • Leave them in a bunch rather than separating out.

  • Remove the outer plastic bag if they came in one.

  • Hang them up to avoid bruising and replicate how they’re stored in nature.

  • If you don’t have anywhere to hang them, place in a bowl – the curved edge matches the curve of the banana and reduces bruising.

  • Keep at room temperature until ripe, then refrigerate after.

  • Store them next to other unripe fruit.

How to keep lettuce fresh
