Frying Oil Monitor

Quantitative,Reliable Management of Deteriorated Oil. IoT Supported With NFC* Technology.

― Is your oil still fresh? ―

Once oil degrades, it must be replaced with new, fresh oil. Continued use of old, degraded oil can have many negative consequences. Not only does it spoil the quality and flavor of food, it may also gravely impact the health of your customers. By managing the quality and condition of degraded oil using quantitative, objective values, you can determine just the right time to change out the oil.

It can also be extremely useful in reducing costs and improving the quality and flavor of your food products.

Efficient management allows you to maximize the lifespan of oil.

As oil degrades, harmful peroxides are produced from the unsaturated fatty acids within the oil. Further oxidation causes the oil to become increasingly degraded. Using this low-quality, severely degraded oil for cooking or frying may lead to serious health issues, such as heartburn or nausea. ATAGO recommends using the DOM-24 to periodically check and monitor the quality of your oil in order to maximize its lifespan.

Titration requires troublesome equipment and time consuming preparation. Using third party labs is rather costly.

The DOM-24 can easily measure oil degradation without any complicated setup. Absolutely no other equipment or preparation is needed.

     Hassle-free and easy to use

Some methods that utilize test strips or reagent kits result in subjective readings. Moreover, it requires technical knowledge and experience.

The DOM-24 provides objective, quantitative values to determine oil degradation. Anyone can obtain precise, reliable measurements regardless of skill or experience.

     User-friendly

     No more wasting supplies or disposing of refuse

     Stable measurement value even at high temperature

Safe, Reliable, and Hygienic

Many people feel uneasy about using potentially dangerous reagents in facilities where food products are produced. The DOM-24 are safe and hygienic which does not utilize any reagents, eliminating the risk of contaminating your food products. The DOM-24 can be completely washed under running water, allowing for thorough hygienic maintenance.

With secured distance from the oil to the hand, safety is well considered preventing from burn injuries.

Measurement history (up to 100 items) can be read by touching a contactless IC card reader / writer connected to a smartphone or a personal computer.

Identifying Oxidized Cooking Oil

Determining oil oxidation at home can be done by color or smell, but in professional kitchens and production sites, the methods below are used.

① Total Polar Materials (TPM)

A method used to determine the degradation of frying oil. Total Polar Materials (TPM) refers to all products present in frying oil due to oxidation processes, including free fatty acids, products of low molecular weight decomposition, and polymerized substances. The EU has adopted a value of 25 to 27% as their acceptable upper limit for fats and oils.

 ② Acid Value (AV)

Acid Value or AV is an index that denotes the amount of free fatty acids caused by hydrolysis. Acid value is a suitable method for evaluating the degree of oxidation for frying oils. Many AV test strips, which can be easily measure the value, are used at food production sites.

 ③ Carbonyl Value (CV)

It is a measurement denoting the amount of aldehyde and ketone produced in frying oils to determine degradation. Carbonyl compounds can be a good indicator of thermal oxidation. In addition, as the threshold is small, it will impact the smell of fats and oils greatly.

 ④ Peroxide Value (POV)

Peroxide is generated when oil is exposed to air, causing the unsaturated fatty acids to absorb oxygen. Peroxide value can also be used to measure hydroperoxide but for frying oil the indicator is by decomposition or polymerization.

Oil Quality Standards

Function and design

DOM-24 Acid Value(AV) Scale model is also available!

Total polar materials (TPM) % is mainly used in Europe as an indicator of cooking oil degradation. TPM is a value that expresses the amount of degraded substances (excluding non-polar materials),such as decomposed substances and polymers, calculated primarily from oils and fats (triglycerides).① In addition to TPM, acid value (AV) is also an indicator used to express cooking oil quality and freshness. It is primarily used in other countries such as Japan and America. AV is a value that expresses the proportionate amount of free fatty acids within oil. ②Values will vary depending on the region and sample.

The DOM-24 is capable of switching between both TPM and AV values for measurement. Please use the scale most suitable to your application.

Introducing a frying oil monitor that can be used to periodically check and monitor the quality of oil.This instrument is capable of measuring both TPM (Total Polar Materials),a standard used in Europe as an indicator of the overall quality of frying oil, as well as AV (Acid Value),which indicates changes in cooking oil properties.
