7 Best Ways To Make Your Cooking Oil Last Longer

10:33 am


Anyone who uses a deep fat fryer on a daily basis knows that one of the most expensive running costs is cooking oil. Here's the seven best ways to extend the lifespan of your oil.

Why Save Oil?

It might seem obvious, but there's some direct benefits to you for saving oil:

  • Save money: wasting oil can be expensive. You may even need to pay for disposal.
  • Save time: constantly changing out oil and cleaning is time consuming.
  • Better resultsfood debris doesn't just look bad on the plate - it can have a negative effect on its taste too.
  • Fryer lifespan: constantly battling against food debris can cause a fryer to work harder than it has to.
  • Environment: extending the lifespan of your oil means you're only using what you need to.

How to Save Oil

1. Skimming

Frying naturally causes food debris to separate into the oil. Keep on top of it by removing any floating food sediment with a Skimmer, a tool specifically designed to help keep oil clean.

2. Cleaning

It may sound obvious, but routine cleaning and maintenance can make all the difference. Don't just clean the tank down - make sure to thoroughly clean the baskets, elements, drain valves, lids and any other part of the fryer which might come into contact with oil. After cleaning, don't forget to dry the components too - cooking oil and water really don't mix.

3. Temperature

Make sure to fry at the correct temperature. It's easy to simply set the fryer at a "catch all" temperature (many just set and forget at 180°C). Not only can this lead to greasy or overcooked results, it also reduces the lifespan of the oil too. Using the right temperature keeps your customers - and your oil - happy.

4. Shake It Off

It's common to add just-coated or frozen food into a fryer. However, frozen food usually has ice crystals which rapidly turn into water in hot oil. Just-coated foods can quickly leave lots of floating debris too.

Shaking off ice crystals and excess breadcrumbs/batter before cooking can make a big difference over time.

5. Filtration

No matter how well you look after it, at some point you'll either have to filter your oil or replace it. Filtration is a pretty quick win and can reduce your frying oil costs by up to 50%.

Generally, only free standing fryers have built-in filtration systems, whereas countertop fryers require a manual cooking oil filter. Other products can be used to expand oil lifespan such as Frypowder, which works to stabilise oil and reduce the amount of oil absorbed by the food.

Vito Oil Filters are perfect for both countertop and free standing fryers, so if you've got multiple unfiltered fryers, it's a great option. Simply transfer the unit between fryers- much more economical than independent filters for each one. The video below shows how these advanced products work.

6. Season After Frying

A really common practice is to season food before frying. The problem is that seasoning only adds more debris to oil, reducing its lifespan. Some seasonings also cause the oil to discolour or even foam up, so it's best to keep the seasoning until after the food is cooked through.

7. Cover Up

Possibly one of the biggest threats to cooking oil quality is air, as it can slowly break down oil by oxidisation. Most commercial fryers will have a lid as standard - simply keeping it covered when not in use is one of the easiest ways to maintain oil quality.
