说明

一般說明

方法：试纸条比色法 0.5 - 1 - 2 - 3 mg/g KOH MQuant^®

油炸会导致油脂随时间分解。分解的主要副产物之一是游离脂肪酸。当这些酸超过可接受的阈值时，它们会影响油炸食品的质量。使用MQuant^® 游离脂肪酸测试可以很容易地监测煎炸油的质量。油或脂肪样品中存在的游离脂肪酸与pH 指示剂反应，根据游离脂肪酸含量的不同指示剂的颜色发生变化。通过目测比较测试条的反应区和色标区域，可半定量测定游离脂肪酸的浓度。

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.

應用

• 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).
