Estimation of Kinetic Parameters of Walnut Oil Using Rancimat Test [PDF]

, 2015
In this paper, walnut oil at four different temperatures (353, 363, 373 And 383 ̊ K) were oxidized under the rancimat test conditions, it was observed that the rate of oxidation increases with increasing temperature.

A preliminary Rancimat-based kinetic approach of detecting olive oil adulteration

LWT, 2018
Abstract Temperature coefficients (TC and Q10 number) and the parameters of Arrhenius equation (frequency factor, A, and activation energy, Ea) and activated complex theory (enthalpy, ΔH++, and entropy, ΔS++) based on the oxidative stability indices (OSI, by Rancimat test at 100–130 °C) were used to detect the adulteration of olive (Zard and Roghani ...

Chemical Profiling of Californian Walnuts (Juglans regia L.) of Chandler, Howard, and Tulare Varieties

Journal of Food Quality, Volume 2026, Issue 1, 2026.
California walnuts are primarily dominated by three cultivars: Chandler, Howard, and Tulare. To thoroughly compare their quality and analytical methods for classification, we sourced these cultivars from multiple growers, collected them during two collection years, and evaluated their lipid and phenolic metabolites. Our findings revealed that Chandler,

Encapsulation of Rosehip (Rosa canina L.) Seed Polyphenols in Polysaccharide‐Based Carriers: Process Optimization, Characterization, and In Vitro Release

Food Science &Nutrition, Volume 13, Issue 12, December 2025.
Rosehip seed polyphenols were encapsulated by optimized spray‐drying using polysaccharide carriers. The microparticles showed strong antioxidant properties and higher release in the intestinal phase. Their incorporation improved the oxidative stability of sunflower and corn oils.

Exploring quinolinone–chalcones: Synthesis, antioxidant potential and industrial applications in biofuels

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1765-1783, November/December 2025.
Abstract Biofuels undergo oxidative degradation, which reduces their storage stability and efficiency, hindering their large‐scale adoption and integration into the global energy matrix. To address this issue, we synthesized and characterized four novel quinolinone–chalcone derivatives (substituted with Br, Cl, OCH3 and OCH2CH3) as potential ...

Oxidative Stability and Molecular Reactivity of Biodiesel from Castor and Cottonseed Oil Blends by Homogeneous and Heterogeneous Catalysis

Energy Technology, Volume 13, Issue 11, November 2025.
The oxidative stability of biodiesel from homogeneous and heterogeneous catalysis of castor/cottonseed oil blends is studied. Castor oil's ricinoleic acid improves oxidative stability, acting as a natural antioxidant. Yet, HT catalysis led to lower stability due to catalyst leaching.
