low molecular weight decomposition products

In the Total Polar Materials (TPM) test, also known as Total Polar Compounds (TPC), low molecular weight decomposition products are a key indicator of oil quality, especially in frying oils. Here's a breakdown: What is the TPM test? The TPM test measures the total amount of polar compounds in oil. These polar compounds are formed as oil degrades due to high temperatures and repeated use, particularly in frying. A high TPM value indicates that the oil has deteriorated significantly and may no longer be suitable for consumption. Low molecular weight decomposition products These are substances formed during the breakdown of fats and oils, and they contribute to the overall TPM value. Some key examples include: Free fatty acids (FFAs): These are fatty acids that have been released from triglycerides (the main component of fats and oils). FFAs can contribute to undesirable flavors and odors in the oil. Aldehydes and ketones: These are formed through oxidation of the oil and can also c...

Total Polar Materials (TPM) test

Total Polar Materials (TPM) testing is a method for measuring the quality of frying oil. TPM testing uses a sensor to measure the percentage of TPM in the oil, which indicates how degraded the oil is.  How it works  A TPM testing device, such as a food oil monitor, is used to measure the oil. The sensor is placed into the oil and stirred gently until the light on the device flashes. The light indicates the quality of the oil. What it measures TPM measures the amount of products in the oil that are created by oxidation processes. These products include free fatty acids , polymerized substances , and low molecular weight decomposition products .  As the oil ages, the TPM value increases.  What it indicates  A TPM value of 9–14% indicates the oil is suitable for cooking. A TPM value of 14–20% indicates the oil is in its optimal frying range. A TPM value of 24% or higher indicates the oil is no longer suitable for consumption. Why it's important  TPM testing is...

polymerized substances

This is for informational purposes only. For medical advice or diagnosis, consult a professional. A polymerized substance is a type of chemical compound that is made up of many repeating units, called monomers. These monomers are linked together to form a long chain, or polymer. Polymers can be found in a variety of materials, including plastics, rubber, and even natural materials like silk and DNA. The properties of a polymer depend on the type of monomers that are used to make it, as well as the way in which the monomers are linked together. For example, some polymers are strong and flexible, while others are brittle and rigid. Polymerized substances are used in a wide variety of applications, including: Packaging: Polymers are used to make food packaging, plastic bottles, and other types of containers. Construction: Polymers are used in a variety of construction materials, such as pipes, siding, and roofing. Transportation: Polymers are used in cars, airplanes, and other vehicles...
