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 […]

Effect of temperature on the quality of fresh crude palm oil at different stages of processing

A study was conducted in two palm oil mills to determine the effect of processing temperature at five different processing units on the quality of production oil. Oil samples were collected at the screw press, vibrating screen, clarifier, purifier and vacuum drier for quality analysis. The quality parameters measured were free fatty acid (FFA), peroxide […]

Yield potential of various sources of planting materials in Malaysia : second round evalution

A total of 100 dura x pisifera (DxP) progenies from seven seed producers (agencies) in Malaysia were evaluated in a comparative trial in Lahad Datu, Sabah, Malaysia. The trial mean for fresh fruit bunch (FFB) was 168.18 kg palm-1 yr-1 and the oil to bunch (O/B) was 22.73%. High FFB yield was largely attributed 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 […]

Genes controlling flowering: possible roles in oil palm floral abnormality

Floral abnormality in clonal oil palm results in bunch failure and a reduction of oil yield. An in-depth study of oil palm flower development is important to understand the factors involved in this phenomenon. Based on the success of flower development studies of Arabidopsis and rice, efforts have been directed at investigating oil palm flower […]
