AbstractThis work presents a comparison between a new method for the determination of the oxidative stability of edible oils at frying temperatures, based on near‐infrared emission spectroscopy (NIRES), and the Rancimat method at 110 °C. In the NIRES‐based method, the induction time (IT) is determined by means of the variation of the emission band at ...

Preservation of gallic acid and methyl gallate on purified Kilka fish oil oxidation by Rancimat [PDF]
AbstractKinetic analysis of gallic acid and methyl gallate in purified Kilka oil was studied in the concentration, range 200–1600 ppm, during autooxidation in Rancimat test at 60°C. The stabilization factor (F), the oxidation rate ratio (ORR), the activity (A), and the mean rate of antioxidant consumption (Winh) were determined. The scavenging activity

The stability of palm oils during heating in a rancimat [PDF]
The crude palm oil (CPO) and refined palm oil (PO) not only have a balance of saturated and unsaturated fatty acids but also have the highest β–carotene and vitamin E compared to others vegetable oils. A series of aliphatic aldehydes starting from hexanal to decanal was identified by LC-MS/MS and quantified as DNPH derivatives.

DETERMINATION OF OXIDATIVE STABILITY OF CRUDE AND REFINED VEGETABLE OILS BY RANCIMAT
The oxidative stability of vegetable oils has been introduced as a critical factor that affects on its quality, shelf life, and nutritional value. In this study, the Rancimat method was analyzed for investigation and comparing the oxidative stability of crude and refined vegetable oils.

Reproducibility of PetroOxy and its correlation with the Rancimat method
The current trend of reducing greenhouse gas emissions and carbon footprint as well as legislation requirements means an increase in the effort to replace fossil fuels by using renewable sources. One of the possibilities is usage of methyl esters (FAME or UCOME) as a bio-component in diesel fuel.

Determination of the oxidative stability of hazelnut oils by PDSC and Rancimat methods [PDF]
The present study was conducted to determine the oxidative stability of hazelnut oil and compare it with more common and previously tested olive oil and rapeseed oil. The oxidative stability was determined by means of two independent methods, pressure differential scanning calorimetry (PDSC), and oxidative stability index (OSI) using TA Instruments DSC
