Promoting of soybean oil oxidation by the addition of menhaden oil
… SO prior to testing. The peroxide, anisidine and Rancimat values were determined at weeks 0, 1, 2, 3, 4, 6, 8 and 10. Fifteen panelists determined the differences in rancidity of the control and M/S using the directional paired-comparison test. The peroxide values of the control peaked at weeks 2 …

Desenvolvimento de um sistema terapêutico emulsionado para uso oral a base de óleo de rã-touro (Rana catesbeiana Shaw)
… dienes and trienes, oxidation induction time (Rancimat®) and changes in the infrared spectra were measured. The bullfrog oil oxidation rate was dependent on temperature, and the oil became more stable in the presence of BHT. During the oil oxidation, significant changes in the ultraviolet …

The oxidation stability of extra virgin avocado oil : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology in Food Science at Massey University
… by examining their affect on EVAO using the Rancimat oil stability index analysis and hot air oven testing. It was found that fluorescent light at 4500 lux and aeration with dry air strongly accelerated the oxidation (determined by PV) and reduced the chlorophyll content of EVAO. The average …

Antioxidant properties of flaxseed lignans using in vitro model systems
… compared to BHT 17 (2.0). The induction time by Rancimat analyzer measured inhibition of autoxidation mediated by flaxseed lignans SECO, SDG and SDG polymer in comparison with BHT 17. The induction time data demonstrated that SECO 2 protected canola oil better than either SDG 1 or SDG polymer 3. …

Oxidative stability and ignition quality of algae derived methyl esters containing varying levels of methyl eicosapentaenoate and methyl docosahexaenoate
… 110 °C and airflow of 10 L/h using a Metrohm 743 Rancimat with automatic induction period determination following the EN 14112 Method from the ASTM D6751 and EN 14214 Standards, which call for induction periods of at least three hours and six hours, respectively. Derived Cetane Number testing was …

Uso de extractos de romero y otras fuentes vegetales como antioxidantes tecnológicos en aceites alimentarios. Estudio comparativo de eficacia frente a antioxidantes sintéticos. Relación estructura-actividad.
… estufa y envejecimiento acelerado por el método Rancimat. En las experiencias de envejecimiento acelerado en estufa se evalúa la capacidad antioxidante tanto a nivel de reducción de compuestos de oxidación primaria (índice de peróxido, IP), como secundaria (índice de p-anisidina, IA). En el caso …
