A comparative evaluation of low-field and high-field NMR untargeted analysis: Authentication of virgin coconut oil adulterated with refined coconut oil as a case study

Epub 2023 Jun 21.ABSTRACTDespite the advances in low-field nuclear magnetic resonance (NMR), there are limited spectroscopic applications for untargeted analysis and metabolomics. To evaluate its potential, we combined high-field and low-field NMR with chemometrics for the differentiation between virgin and refined coconut oil and for the detection of adulteration in blended samples.

Effects of different fats on postprandial appetite responses: a randomised crossover trial
This study aimed to investigate the impacts of type and emulsification of fat on postprandial appetite responses. Sixteen healthy subjects participated in a 4-arm, randomised, crossover study. The net iAUC of hunger visual analogue scales (VAS) (mean ± SE) was observed higher with emulsified fat (-512 ± 137 cm × 300 min) than with non-emulsified fat (-785 ± 133 cm × 300 min) (p < 0.05), but the difference became insignificant over time. Compared to olive oil, coconut oil resulted in higher fullness VAS iAUC (olive oil: 1369 ± 306 cm × 600 min; coconut oil: 1786 ± 311 cm × 600 mi, p < 0.05). Findings from thi...

Molecules, Vol. 28, Pages 4661: Multivariate Curve Resolution Methodology Applied to the ATR-FTIR Data for Adulteration Assessment of Virgin Coconut Oil
In this study, the use of Fourier transform infrared (FTIR) spectroscopy combined with multivariate curve resolution&ndash;alternating least squares (MCR-ALS) methodology was evaluated to verify the purity or adulteration of VCO with reference to low-cost commercial oils such as sunflower (SO), maize (MO) and peanut (PO) oils. A two-step analytical procedure was developed, where an initial control chart approach was designed to assess the purity of oil samples using the MCR-ALS score values calculated on a data set of pure and adulterated oils. The pre-treatment of the spectral data by derivatization with the Savit...
