The main objective of this study is to investigate some quality characteristics based on which we can evaluate oxidative stability of coconut oil during 12 month of storage. The progress of lipid oxidation was assessed by measuring peroxide value (PV), p-anisidine value (AV) and total oxidation value (TOTOX). The low peroxide value (0.24–0.49 meq/kg oil) signifies a high oxidative stability, while p-anisidine values were in the range 0.19-0.87. Fourier transform infrared (FTIR) spectroscopy was…

Physico-chemical Characteristics and Oxidative Stability of Date-Pits Oil during Storage at Different Temperatures
Abstract In this study, oxidative stability of date-pits (i. e. Khalas variety) was investigated during storage as a function of temperature. The stability of date-pits oil was determined by
Oxidative properties of Moringa oleifera kernel oil from different extraction methods during storage.
TLDR
Findings are significant in highlighting the extraction method resulting in crude MO kernel oil with greatest oxidative stability in the storage conditions tested, and the suitable storage condition of the oil prior to refining can be determined.
The effect of temperature on rice oil bleaching to reduce oxidation and loss in bioactive compounds
Refining conditions are very important to obtain high-quality rice oil. This work aimed at evaluating the effect of bleaching temperature in chemical and physical refining processes to avoid losses
Catole coconut (Syagrus cearensis) oil: physicochemical characterization and thermo-oxidative stability by TG/DTG/DTA and Rancimat
Vegetable oils are subjected to heat treatments during processing and changes during storage. Thus, it is required, for usage as a food source, the evaluation of their thermo-oxidative stability and
Effect of ultrasound treatment on oxidative stability of sunflower oil and palm oil
  • 2018
This study aims to investigate the effect of sonication time (2-120 mins) on lipid oxidation and accelerated storage of ultrasound treated sunflower oil (UTSO) and ultrasound treated palm oil (UTPO).
THE DEVELOPMENT OF NATURAL ANTIOXIDANT ACTIVE EHURU POLYSULFONE FILM AND ITS EFFECT IN LIPID OIL STABILIZATION
A natural antioxidative Monodora myristica (Ehuru) active film package for lipid food preservation was produced by cast method. 0 5% w/w ehuru antioxidant extract (EAE) was incorporated into PSF

Quantitative analysis of virgin coconut oil in cream cosmetics preparations using fourier transform infrared (FTIR) spectroscopy.
TLDR
F Fourier transform infrared (FTIR) spectroscopy with sample handling technique of attenuated total reflectance (ATR) can be successfully used to analyze VCO quantitatively in cream cosmetic preparations and revealed a good relationship between actual value and FTIR-predicted value of VCO.
Reaction of oxygen and unsaturated fatty acids
Oxygen reacts readily with unsaturated fatty acids so that every time these compounds are handled there is a danger they will become contaminated with oxidation products. The products formed first
