How to extend the life of your cooking oil…

  • Cooking oil lasts longer if it is filtered on a daily basis. But this can be a time consuming and even hazardous operation – which has prompted our introduction of three new, heavy duty Opus 700 commercial fryers with on-board filtration – see new product notes below. These new models have the capacity to extend the life of your cooking oil by up to 50%.
  • If you filter the oil manually, make sure it is at the optimum temperature before you start: 40°C is ideal. Too hot and you run the risk of serious burns, too cold and the oil becomes viscous and can take longer to filter. Use a good temperature probe to be certain.
  • Filter oil into a metal container standing on a metal tray to minimise the risk of spills. Always dispose of oil in an environmentally friendly fashion via a licensed waste oil collection service; you can’t just pour it away no matter how small the amount.
  • Do everything you can to keep your frying oil really clean. Always remove residual food particles from the oil with a wire spider. If left in the fryer they will carbonise, taint the flavour of the food and reduce the life of the oil.
  • Take the frying baskets out of the oil when not in use and use the dust covers. This will help to keep the oil as clean as possible – even oxygen contributes to oil degradation over time.
  • Clean your fryer thoroughly and make sure that it is completely dry before you load new oil. Water contamination will significantly reduce the life of your cooking oil.
  • Wet food and fryers don’t mix! Ensure that all food you are cooking is as dry as possible, so remove ice from frozen products before cooking them. Not only will this prevent spitting, but it will also extend the life of the oil.
  • In short, look after your oil and it will look after you, and always keep your fryer topped up as the food absorbs the oil whilst cooking.

    Thanks for you comments Liz.

    There are many different factors that you need to take into consideration when deciding on the type of cooking oil that you need, such as how often you will be cooking, the main type of food you will be cooking, along with price and quality as you want to make sure that you get a good deal.

    My best advice would be to speak with the wholesaler that you currently purchase your food from, they will beable to recommend something to you. Also it might be worth considering buying from someone that offers waste management of the oil also, do they collect? How often? etc As waste oil can be a pain to find/transport to your local oil bank.
