Description

General description

Palmitic acid belongs to the group of saturated fatty acids and accounts for 20-30 % of the total fatty acids present in the human body.

This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food.

Application

This analytical standard can also be used as follows:

• Development of a non-destructive Vis-NIR reflectance spectroscopy-based method for the detection of four fatty acids in 93 samples of seven different edibles oils
• Simultaneous identification and quantification of fatty acids from blood plasma samples after their methyl derivatization by large-volume injection (LVI) gas chromatography combined with vacuum ultraviolet spectroscopy (GC-VUV)
• Determination of the fatty acid composition of sunflower seed oils extracted from 93 different sunflower varieties by near-infrared reflectance spectroscopy (NIRS) combined with modified partial least squares (MPLS) and partial least squares (PLS) regression methods
• Separation and quantification of palmitic, oleic, linoleic, and linolenic acids from 186 samples of sea buckthorn seed oil using near-infrared spectroscopy (NIR) in combination with four different combinations of multivariate calibration methods— partial least squares (PLS), PLS-uninformative variables elimination (UVE), PLS- competitive adaptive reweighted sampling (CARS), and multiple linear regression (MLR)-UVE
• Quantitative analysis of various bioactive compounds from the ethanolic extract of sesame seeds by gas chromatography-mass spectrometry (GC-MS)
• Multi-residue analysis of oleic acid and other related fatty acids using a derivatization-free method based on gas chromatography-flame ionization detection (GC-FID)
• Ultra-performance liquid chromatography-mass spectrometry (UHPLC) method-based separation, identification, and determination of eight saturated and unsaturated fatty acids in eight different commercial samples of olive oil without any prior sample treatment
• Development of a liquid chromatography-mass spectrometry (LC-MS) method to measure seven fatty acid esters of hydroxy fatty acids (FAHFAs), four fatty acids, and four cardiovascular-related biomarkers in plasma samples of 57 healthy individuals
