Characterization of Volatile Compounds with HS-SPME from Oxidized n-3 PUFA Rich Oils via Rancimat Tests

open access: yesJournal of Oleo Science, 2017
Algae oil and fish oil are n-3 PUFA mainstream commercial products. The various sources for the stability of n-3 PUFA oxidation are influenced by the fatty acid composition, extraction and refined processing. In this study, the oil stability index (OSI) occurs within 2.3 to 7.6 hours with three different n-3 PUFA rich oil.

Rosemary Extracts Improved the Antioxidant Status of Low-Fat Yoghurt Sauces Enriched with Inulin

open access: yesAntioxidants, 2022
Yoghurt sauces are considered fatty products which are quite susceptible to oxidation and must be stabilised using antioxidants. Novel formulations for yoghurt sauces often involve replacement of fat with dietary fibres and use of natural preservatives ...

Evaluation of Antioxidant Potential and Chemical Composition Blends of Sunflower Oil (Helianthus annuus L.) with Coconut Oil (Cocos nucifera L.)

open access: yesOrbital: The Electronic Journal of Chemistry, 2019
Coconut oil has more than 90% of saturated fatty acids. Of this percentage, about 47% of lauric acid, an important saturated acid that gives great stability to oxidation, in addition to benefic properties such as anti-inflammatory.

Enhancing the Multifunctional Qualities of Palm Oil With Plant‐Derived Essential Oils: An Integrated HPLC and RSM Approach

open access: yesFood Science &Nutrition, Volume 14, Issue 4, April 2026.
The results established that the treatments obviously retard the thermal degradation and hydrolytic decomposition of the palm oil, which can be attributed to the antioxidant effects (high phytochemical content) of the essential oils used as the treatment material. Markedly, the bio‐fortified palm oil samples recorded greater nutritional, physiochemical,
