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 […]

Minor components of palm oil

Minyak sawit mentah mengandungi banyak komponen surih yang mustahak seperti karoten, vitamin E, sterol, squalene, phospholipid dan ubiquinone. Walaupun komponen ini hanya 1% tetapi nilainya tinggi. Kebanyakannya dimusnah atau dikeluar dari minyak sawit dalam proses penapisan. Ini merugikan industri sebab komponen surih ini boleh dipulih. Beberapa komponen ini mempunyai ciri mustahak dalam bidang perubatan dan […]

A note on the long-term palm oil yield trend

National data for Malaysia on annual palm oil yields per hectare were re-examined in the light of their apparent lack of improvement over the last few decades. Published yields were compared to yields re-calculated from basic data on total crude palm oil (CPO) production and mature planted area. While some discrepancies were evident between the […]

Characteristics of simple and chemically interesterified blends containing palm stearin, sunflower oil and palm kernel olein and potential application of the blends in fats spread formulations

Palm stearin (POs), sunflower oil (SFO) and palm kernel olein (PKOo) were blended in various ratios and subjected to chemical interesterification (CIE). Fatty acid composition, triacylglycerol (TAG) composition, solid fat content (SFC) and polymorphic behaviour of the interesterified blends were analysed and compared with the properties of the unreacted blends. Upon CIE, extensive rearrangement of […]

A survey on cosmetic products marketed in Malaysia: microbiological aspect

Cosmetic products contain variable amounts of nutrients that support microbial growth. Most contaminants in cosmetic products include bacteria suchas Staphylococcus, Pseudomonas, Klebsiella, Achromobacter andAlcaligenes. Contaminated water is a likely source of organisms found in cosmetic products. Products such as shampoo, hand and body lotion, facial cleanser, shower bath and moisturizer were analysed. In this study, […]

Polymorphic behaviour of blends of palm oil and palm olein with sunflower oil and palm kernel olein as affected by blending and interestification

Palm oil (PO) and palm olein with an iodine value of 60 (POo-I.V.60), were blended with sunflower oil (SFO) and palm kernel olein (PKOo) according to the conventional three-component mixture design. The effects of blending and chemical and enzymatic interesterification on the polymorphic behaviour of the ternary blends of PO/SFO/PKOo and POo-I.V. 60/ SFO / […]
