Influence of antioxidants on oxidative stability of the oil Chia (Salvia hispanica L.) by rancimat
Oxidative rancidity, known as autoxidation, is the main cause of deterioration of oils and fats, which can be controlled by the use of antioxidants increasing oxidative stability and shelf life. Chia oil is rich in polyunsaturated fatty acids (PUFAs), particularly omega-3 (ω-3) and omega-6 (ω-6) beneficial to human health, but PUFAs also favor the ...

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 ...

Impact assessment of mechanical harvest on fruit physiology and consequences on oil physicochemical and sensory quality from ‘Manzanilla de Sevilla’ and ‘Manzanilla Cacereña’ super-high-density hedgerows. A preliminary study [PDF]
BACKGROUND Super-intensive cultivation facilitates olive mechanized harvesting, allowing substantial savings in the production cost of virgin olive oil (VOO). However, the number of varieties adapted to this type of cultivation is small.

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 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.
