Effective Oil Management
Looking after your frying oil is easy. Just follow our Top Ten Tips in our Prep: Frying Oil Management guide.
When to change your frying oil?
One of the most important parts of using frying oil is knowing when it’s time to discard it. The most obvious signs are the oil changing colour and becoming dark. The food's taste and appearance also start to suffer, but by then it's too late!
Regular testing will show you when your oil is getting close to the end of its useful life - long before it has a chance to ruin your customers’ well-earned meals. Testing can be as simple as using our Prep Sticks and comparing them with the Prep colour chart.
We want to help you maximise your return on the investment you have made in Prep, through our unique oil management programme.
Acrylamide is a naturally occurring chemical substance, formed by a reaction between amino acids and sugars.
It occurs typically when foods with a high starch content, such as potatoes, root vegetables and bread, are fried, roasted, or baked at temperatures over 120°C.
Therefore, we recommend frying at a maximum of 175°C or lower if possible. Where appropriate, cook for longer at a lower temperature but always ensure foods are properly cooked!
It is widely agreed that acrylamide has the potential to cause cancer and is therefore a risk to human health. Since 2018, foodservice operators have had a legal duty to take steps to manage acrylamide in food.
Careful oil management is one of the simplest and most effective ways to comply with the legislation.
What is TPM?
Total Polar Material (TPM) builds up in the oil during regular use and measuring these levels (as a percentage) is one of the most reliable and accurate measures of oil quality and cleanliness of frying oil.
FRESH OIL: 7% TO 10%
TPM MID LIFE (OPTIMUM FRY): 17% TO 18%
DISCARD POINT: 25%
We recommend that oil be discarded when the TPM reaches 25%, in line with European legislation.
How can TPM be measured?
We recommend using a Testo 270 Cooking Oil Tester, which can accurately measure TPM levels in a few seconds. It provides clear notifications to kitchen teams, so they know when it’s time to make a change. Over time, this can help to reduce oil consumption by up to 20%, whilst guaranteeing you are cooking with clean, effective oil.
