General description

Method: Colorimetric with test strips, 0.5 - 1 - 2 - 3 mg/g KOH, MQuant®

Deep-frying causes oils and fats to decompose over time. One of the major by-products of decomposition is free fatty acids. When these acids exceed an acceptable treshold, they affect the quality of fried food. With MQuant® Free Fatty Acids, it is easily possible to monitor the quality of deep-frying oil. Free fatty acids present in an oil or fat sample react with a pH indicator, the color of which changes depending on the concentration of the free fatty acids. The concentration of the free fatty acids is measured semi-quantitatively by visual comparison of the reaction zone of the test strip with the fields of a color scale.

Design for sustainability benefits:

We continue to demonstrate our commitment to our planet and a sustainable future by exploring ways to improve existing products in our portfolio. We have recently reviewed the current line of MQuant® test strips to identify key opportunities to minimize impact without compromising on the product performance.

This product has benefited from:

  • Test strip with reduction
  • Recycled aluminum tube
  • Digital instruction leaflet

    Application


    • Influence of oleogel composition on lipid digestibility and beta-carotene bioaccessibility during in vitro digestion.: This study examines how different oleogel formulations affect the digestibility of lipids and the bioaccessibility of beta-carotene during digestion, which is relevant for food chemistry and nutrition, particularly focusing on the behavior of free fatty acids within these matrices (Ramezani M et al., 2024).

    • A new chemical derivatization reagent sulfonyl piperazinyl for the quantification of fatty acids using LC-MS/MS.: This article introduces a new reagent for enhancing the detection and quantification of fatty acids in liquid chromatography-mass spectrometry, important for analytical chemistry applications focusing on the accurate measurement of free fatty acids in various samples (Li S et al., 2024).
