Determination of the induction period of soybean oil - Correlation between the Rancimat and various analytical tests

open access: yesGrasas y Aceites, 1992
The objective of this research work was to follow the evolution of peroxide, anisidine, totox. iodine and acid values and refractive index during the oxidation of soybean oil using the Rancimat method. Various temperatures were used in this case (110°, 120°, 130° and 140°C) and the oxidation curves obtained through the Rancimat were compared with those

Fluorescent light and sunlight radiations may improve rice bran oil colour and influence its oxidative stability and chemical composition

open access: yesFood Biomacromolecules, Volume 3, Issue 1, Page 71-80, March 2026.
Abstract The influence of pretreatment of rice bran oil using fluorescent and sunlight radiations on its colour and their influence on its chemical composition and oxidative stability were assessed. Rice bran oil was stored under sunlight, fluorescent light and ambient conditions for 60 days. Oil samples were collected every 15 days for analysis.

Improving the Oxidative Stability of Oil Extracted From Camelina Seeds Using Green Tea and Lemongrass Extracts

open access: yesJournal of Food Biochemistry, Volume 2026, Issue 1, 2026.
Camelina oil, rich in polyunsaturated fatty acids (PUFAs) and α‐linolenic acid, exhibits a high susceptibility to oxidative degradation, which compromises its shelf life. This study aimed to evaluate the potential of green tea (GE) and lemongrass (LE) extracts at concentrations of 200 and 500 ppm, compared to 200 ppm BHT, in stabilizing camelina oil at

Comparação dos métodos de determinação da estabilidade oxidativa de biodiesel B100, em mistura com antioxidantes sintéticos: aplicação do delineamento simplex-centroide com variável de processo Comparison of methods for determination of oxidative stability of B100 biodiesel mixed with synthetic antioxidants: application of simplex-centroid design with process variable

open access: yesQuímica Nova, 2013
The Rancimat and accelerated stove tests were used to determine the oxidative stability of B100 biodiesel mixed with synthetic antioxidants. The predictive equations, with process variable, were obtained by applying a simplex-centroid design.
