Introducing a Atago 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.

Features:

• Hassle-free and easy to use: Titration requires troublesome equipment and time consuming preparation. Using third party labs is rather costly. The DOM-24 can easily measure oil degra-dation without any complicated setup. Absolutely no other equi-pment or preparation is needed.
• User-friendly: 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 degrad-ation. Anyone can obtain preci-se, reliable measurements rega-rdless of skill or experience.
• No more wasting supplies or disposing of refuse: Unlike titration and test strips, which produce refuse,the DOM-24 do not generate any waste or refuse, which means you do not have to worry about disposal. Additionally, unlike reagents, the DOM-24 does not have any sort of "expiration date."
• 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.
• Stable measurement value even at high temperature: The DOM-24 is equipped with automatic temperature comp-ensation (ATC), making it cap-able of measurements at a wide temperature range of 0°C to 225°C. The DOM-24 can provide stable and reliable measureme-nt values, even at high temper-atures.
• IoT Enabled: Measurement history (up to 100 items) can be read by touching a contactless IC card reader / writer connected to a smartph-one or a personal computer. The N-Mark is a trademark or registered trademark of NFC Forum, Inc. in the United States and in other countries.
• IH Heater compatible (patented): The DOM-24 is the only oil checker that can be used with IH heaters by attaching the sensor cover.

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.   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. 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. 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. 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:

Instant noodles		The acid value of fats and oils contained in noodles should not exceed 3 or the peroxide value should not exceed 30.	Standards for Foods, Food Additives
		In fats and oils of noodles dried by oil treatment should be 1.5 or less. The acid value of fats and oils used for oil processing of noodles should be 1.5 or less.	Japanese Agricultural Standard
Confectionery processed with fats and oils (containing 10% or more of fats and oils)		Selling products that conform to the following (a) and (b). (a) For confectionery products, the acid value of fats and oils contained in their products should not exceed 3, and, the peroxide value should not exceed 30. (b) The confectionery should not exceed an acid value of 5 or more in the fats and oils contained in the product or, the peroxide value should not exceed 50.	Confectionery Guidelines
Bento box and side dish		As raw materials: Use those with an acid value of 1 or less (but excluding sesame oil) and a peroxide value of 10 or less. Frying with fats and oils: If the acid value exceeds 2.5, replace with fresh fats and oils.	Health Code for Lunch Box and Side Dish
Western-style confectionery		(1) Component specification of raw materials: acid value 3 or less, peroxide value 30 or less (2) Products shall conform to the following standards ?The acid value of fats and oils contained in the product does not exceed 3. ?The peroxide value of fats and oils contained in the product does not exceed 30.	Healthy Norms of European-style Confectionery
Edible vegetable oils and fats	Oil with low degree of purification	Acid value of 0.20 to 4.0 or less. (Cottonseed, sesame, rapeseed, peanut, olive, palm olein, palm stearin, mixture, flavor oil)	Japanese Agricultural Standard
	Refined oil	Acid value of 0.20 or less (Olive oil has an acid value of 0.60 or less)
	Salad oil	Having an acid value of 0.15 or less (the one prepared with olive oil has an acid value of 0.40 or less)

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. (1) 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). (2) 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. Values 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.
