Performance Evaluation of Rice Bran Oil—Waste Cooking Oil Binary Blend‐Based Biodiesel With Normal Diesel in CI Engine

Engineering Reports, Volume 8, Issue 2, February 2026.
This study evaluates the performance and emissions of CI engines using biodiesel blends derived from rice bran and waste cooking oil, revealing that a 30% biodiesel blend significantly reduces emissions, while a 70% blend affects specific engine parameters. ABSTRACT This research investigates the performance, combustion, and emission characteristics of

Interesterification of Rice Oil

Journal of Japan Oil Chemists' Society, 1967
Rice oil (cloud point 0.5°C) was interesterified by the action of a small amount of sodium methoxide (0.1-0.50), and it was winterized to give an oil having a low cloud point (-6°C).

Dietary Sources, Estimated Intake, and Health Risks of Industrial Trans‐Fats in Lebanon: Findings From the LEBANON National Food Consumption Survey (LEBANON‐FCS)

Journal of Food Processing and Preservation, Volume 2026, Issue 1, 2026.
This study is aimed at assessing industrially produced trans‐fatty acid (iTFA) consumption in a nationally representative sample of the Lebanese population and characterizing the associated risk of CHDs. Validated food frequency questionnaires (FFQs) and two nonconsecutive 24‐h recalls were used to collect dietary intake between January 2022 and August

Revisiting the mechanisms of low-temperature, base-catalysed ester interchange reactions

Oléagineux, Corps gras, Lipides, 2008
Ester interchange reactions such as the interesterification of triglycerides and their transesterification with methanol (methanolysis) to produce FAME (biodiesel) nowadays invariably use a basic catalyst such as an alkali alcoholate or hydroxide ...

Sustainable Recovery of Plant Lipase From Pequi Peel (caryocar brasiliense camb.) in Aqueous Two‐Phase Systems: An Optimization Approach

ChemistrySelect, Volume 10, Issue 46, December 8, 2025.
ABSTRACT While plant residues represent promising low‐cost enzyme sources, their efficient recovery remains a challenge for industrial biocatalysis. This study aimed to optimize thepurification of lipases extracted from pequi peel (Caryocar brasiliense Camb.) using aqueous two‐phase systems (ATPS) composed of polyethylene glycol (PEG) 1500 g/mol and ...

Competitive Interesterification-Transesterification of Rapeseed Oil with Methyl Acetate in Presence of Potassium Metoxide Solutions

, 2018
Two catalytic systems (CH3OK/CH3OH and CH3OK/tert-BuOH) were tested to estimate competitive interesterification-transesterification processes of rapeseed oil with methyl acetate. Catalyst completely dissolves in methanol, while in tert-butanol suspension
