Determination of process contaminants 2- and 3-MCPD esters and glycidyl esters in palm-based glycerol by indirect analysis using GC-MS.

Esters of 2- and 3-monochloropropanediol (2-MCPDE, 3-MCPDE) and glycidol (GE) are regarded as process contaminants that are found in refined vegetable oils and oil-based foods. Since glycerol is produced during fat splitting, saponification and biodiesel production, it is important to have methods for determining contaminants that might be formed during these processes. Due to the use of glycerol as a food additive, data on the presence of compounds of toxicological concern, including 3-MCPD, are of interest.

Growth of Marine Microalgae in Landfill Leachate and Their Ability as Pollutants Removal.

Leachate from landfill contains concentrated nutrients that may enter the terrestrial and aquatic environment, including nearby coastal areas. The nutrient contaminants eventually bring harm to marine organisms, including microalgae. This study was performed to investigate the growth of two green microalgal species, sp.

Stability evaluation of quality parameters for palm oil products at low temperature storage.

Background: Palm oil is one of the major oils and fats produced and traded worldwide. The value of palm oil products is mainly influenced by their quality. According to ISO 17025:2005, accredited laboratories require a quality control procedure with respect to monitoring the validity of tests for determination of quality parameters.

Performance of Palm-Based C Methyl Ester Sulphonate (MES) in Liquid Detergent Formulation.

Liquid detergents are more convenient than powdered detergents as they dissolve readily in water, generate less dust and dosing is easy. However, the stability of liquid detergents is an issue of concern. Therefore, the objective of this research is to study the formulation requirement to produce heavy-duty liquid detergents based on palm-based methyl esters sulphonate (MES) with desirable properties and performance.
