Guest blog: making food last longer and go further

Date : 18 June 2020

At a time with strict social distancing rules in place and many of us spending more time at home, our shopping habits have shifted significantly. Despite this, a recent survey suggests UK citizens have risen to the challenge of lockdown by making food they buy last longer and go further1. In this article, Dietitian Dr. William Cook shares five top tips on keeping food fresh and reducing food waste during lockdown.

Use up your fresh ingredients first

You don’t want any food to go to waste, so use up perishable ingredients before foods with a longer shelf life.

Know what keeps longest

Some fresh foods have a relatively long shelf life. This includes root vegetables such as potatoes, sweet potatoes, carrots, onions.

Think about where to store food to keep it fresher for longer

Carefully wash, rinse and drain salad leaves and fresh herbs and spin dry in a salad spinner, place into a suitable plastic storage tray, cover and keep refrigerated. By following this procedure your salads and fresh herbs will last for several more days than if just stored in the fridge un-covered.

It might seem obvious but make sure you aren’t storing things in your fridge that don’t need to be in there. For example, fresh tomatoes, un-peeled onions, un-peeled jacket potatoes, whole butternut squashes don’t need to be stored refrigerated. Removing these items from your fridge and storing them in a cool dark place will free up valuable fridge space for more perishable items.

Declutter your cupboards

If you are stuck at home, take the opportunity to tidy and declutter your kitchen cupboards to free up space for ambient food products.  This is a great opportunity to get rid of those unused & unwanted items that end up “living” in your valuable storage space. Remember to re-cycle as many of the items you are discarding as possible.

Useful store cupboard ingredients, other than dried pasta, include:

  • Long grain rice  
  • Couscous / Bulgar wheat
  • Curry pastes
  • Tinned or powdered coconut milk
  • Tinned & dried pulses
  • Chopped & Peeled plum tomatoes
  • Dried herbs (these could replace fresh if required)
  • Tinned fruits in juice
  • Ambient pouches or canned tuna
  • Tinned sweetcorn
  • Frozen fruits

Plan ahead

If you do get sick, it is worth having some easy to cook and prepare foods in the house on standby.  Canned soups, microwavable rice and frozen ready meals are easy options that you can keep in stock if you don’t have the energy to prepare more complex recipes.
