Additives for petroleum fuels and lubricants, biofuels and biolubricants – a review

Biofuels and biolubricants are renewable and biodegradable. These vegetable-based fuels and lubricants have been thoroughly studied in Europe, Asia and America for their fuel and lubrication properties. So far, the biofuels have been found suitable as a diesel substitute. However, engines running on biofuels show some drawbacks in creating performance criteria such as power output […]

Intensive IPM for mangement of oil palm pests

Oil palm is an important crop to Malaysia because of its huge hectarage (3.3 million hectares) and because of its significant contribution to the foreign exchange earning to the country. However, localized losses attributable to a number of pests can be substantial if high pest populations or outbreaks occur persistently. Intensive integrated pest management (IPM) […]

Acute moisturizing effects of palm-based lotions

An acute moisturizing efficacy study was conducted by using MPOB’s palm-based cosmetic products namely Palmianis lotion with vitamin E, goat’s milk lotion and Whitening Lotion 1. A total of 13 volunteers were involved in the study. The skin hydration was measured several times at different intervals (30, 60, 90, 120 and 180 min) after a […]

Characterization of sludge palm oil

A total of 12 analyses were carried out on sludge palm oil (SPO) to determine the most suitable parameters for characterizing this oil. The parameters usually employed for characterizing palm oil are free fatty acid (FFA) content, slip melting point, moisture and impurity content, iodine value (IV) and colour. All these parameters were found to […]

Metabolic control analysis – theory and experimental application

This paper discusses the theory, concept and experimental application of metabolic control analysis. This technique has provided a means by which a quantitative description of control structure by an enzyme, substrate and cofactor over a metabolic pathway can be produced. Application of metabolic control analysis results in numerical values (flux control coefficients) showing how much […]

Improvement of credibility in the analysis of palm oil through SAMM Accreditation – the MPOB experience

All palm oil refineries in Malaysia have basic laboratory facilities to monitor the quality of palm oil produced. To improve their credibility in the analysis of palm oil, their laboratory quality system should be strengthened. The laboratory should use recognized or official methods of analysis, and follow internationally recognized laboratory practice. Skim Akreditasi Makmal Malaysia […]
