How to save money and guarantee cooking oil quality

Whilst many have now adopted technology to test their cooking oil, still a significant number of restaurants and food service providers don’t have a suitable system in place for when to change the oil in their fryers. Generally, restaurants fall into one of 2 categories; either they are changing their oil too frequently, or in some cases not often enough. Both cases create serious issues for the affected company, issues which ironically, are very easily rectified.

Without a system in place, there is no way you can guarantee you are being economical in terms of oil consumption. If you change your oil on a particular day of the week for insurance, or even just sporadically as and when you remember / see fit, you are likely not being as economical with your oil as you could be. In this case, you would certainly benefit from employing a system to optimise frying oil usage.

Often companies simply change cooking oil based on mundane things like the colour of the oil, which is by no means an effective indicator of the stage the oil is at. A change in colour could be caused by something like colouring in the food, which then has no bearing on the oil still being usable. In which case, you may find you losing money, and again would benefit massively by optimising your oil usage. In some extreme cases, we have found companies save as much as 20% on oil consumption, simply by testing it on a regular basis. This soon adds up, especially when you think about this expenditure over the space of a year.


Many food service companies aren’t changing thier oil regularly enough


“But what if I discover I’m not changing my oil enough?” I hear you say. Well here you have an even bigger incentive to test your oil regularly. Using oil which is past the curve has potential to create a number of major issues. Firstly, you run the risk of producing a poor standard of fried food. With overused oil the fried shell is less crisp and the food absorbs much more oil than usual. The batter can become saturated with oil, giving you a greasy end product. This can then leave a bitter, unpleasant taste and very greasy due to a higher content of saturated fats.

Secondly, as the oil continues to age, the product produced is can become hard, oily and there is an added risk with using such aged oil, as this can also cause problems with the inner food (for example chicken, potato) not actually cooking properly. This, of course, could lead to a whole new list of problems for any company serving food, and can then cause problems from a food safety point of view.

Thirdly and perhaps most importantly, you won’t produce a consistent level of product quality. Ever wondered how multinational fast-food companies able to supply such consistent, fried products across the world? The answer is regular cooking oil testing.

In this situation, yes ok, you may not necessarily save money in the short term; but when you consider the long-term reputation of your restaurant or restaurant chain, you absolutely will be protecting your brand’s image. Producing a consistent, quality fried product, supports restaurants in their ongoing pursuit of being seen as a trusted, reputable and sustainable food brand.

Testo Charity Challenge update – 25,000km target reached!


We’ve done it – target reached!

Great news! The Testo team have now reached our target of 25,000km for the testo Charity Challenge.

This is such fantastic news and means Treloars School & College will now receive the maximum donation of £10,000. Well done and a massive thank you to everyone participating, I think we can all agree this has been such a great challenge to be a part of and have all really got behind it.

The official end date for this challenge is 22nd September, so although we have reached our target, you can still carry on with the challenge. And whilst the weather is still nice (with the exception of today of course!), we can all try and stay active and continue to log our km’s in the app. Maybe you could set your own target for km’s achieved by 22nd Sept, or maybe some friendly competition with someone on the leaderboard.

Below is some more about Treloars and the challenge, as well as some of the best pictures we’ve had throughout the challenge. Again, we’d like to reiterate a huge thank you to all involved for making this possible! Great job!


About the Testo Charity Challenge

As you might have heard, Testo is turning 60 this year. To celebrate this outstanding landmark, Testo decided to organise a worldwide charity challenge with the aim to become fitter as a team and to donate some of our profit for a good cause. In addition to the global Testo challenge we have decided to create a local challenge for all employees, family, friends, partners and everyone associated with Testo UK.


Team Testo reached new heights – here we are on top of the highest mountain in England – Scarfell Pike


The goal set for the UK Team Testo was to achieve 25,000km of running, walking or cycling from by 22/09/2017. For every active kilometre achieved by our UK team, Testo Limited would donate £0.40 to the Treloar school and college for handicapped children.


A great challenge for a great cause

Treloar is an incredible organisation in Alton that helps more than 150 physically disabled children from all over the UK to learn and live an independent live. 80% of all students at Treloar’s suffer from a very challenging form of cerebral palsy or muscular dystrophy and 50% have to communicate with the support from augmentative communication equipment. For those of you who have not heard about Treloar, please have a look at the following link:
