(MPOB Transfer of Technology)
Polyglycerols and their derivatives have a broad range of applications (Table 1). MPOB has developed a process to produce polyglycerols (Figure 1) by microwave heating with a substantially reduced reaction time. Glycerol is polymerized at elevated temperatures, preferably 250ºC-270ºC, in the presence of a catalyst. However, a drawback is the tendency to produce highly coloured … Read more
The skin is a barrier between the body and the environment, and any stress imposed by the environment can affect it. Cracked heels are a common foot problem, generally occurring in hot tropical climates, but also in summer and winter in the temperate countries. Heels crack from excessive water loss from the skin, causing it … Read more
Hand dish washing detergents remove food soils, hold soil in suspension as well as provide long-lasting suds to indicate how much cleaning power is left in the wash water. They are available as liquids, gels, powders and solids. MPOB has developed a firm, mild, good performing, low-smear solid dish washing product from palm sulphonated methyl esters … Read more
With soaring petroleum prices, polyols from vegetable oils are increasingly viable alternatives to petroleum polyols. MPOB has developed a palm-based polyol for the polyurethane (PU) industry, which consumes 4.5 million tonnes worldwide annually. The polyol is produced from palm fatty acids, and can be made into PU coating, adhesives, sealants and elastomers. The fatty acids … Read more
Three palm-based polyols (POP) were produced from blending different oils. By varying the blending ratio and using oils with different degrees of unsaturation, a wide range of polyols (with different hydroxyl numbers and viscosity) can be produced. The wider the range of hydroxyl numbers, the more the types of polyols that can be produced for … Read more
Generally, there are three ways to make soap stock: 1) saponification of oils/ fats, 2) neutralization of fatty acids, and 3) saponification of fatty acid methyl esters. Route (2) is more widely used, being the simplest and fastest, while (3) produces the best quality product although at somewhat greater cost. A conventional clear bar soap … Read more
There are three main types of bar soaps – opaque, translucent and transparent. The latter two are becoming increasingly important and gaining market share. They have an aesthetic appeal and are much milder than opaque soaps. Between them, transparent soap is more popular and commercially more attractive to produce. Consumers associate transparency with purity and … Read more
Tocotrienol-enriched egg was developed at the Energy Protein Centre (EPC), MPOB in Keratong, Pahang. It was technically feasible to produce tocotrienol-enriched chicken eggs through feeding formulated feed with tocotrienolrich fraction (TRF) and/or MPOB-HIE. Tocotrienol and vitamin E enhanced oxidative stability and prevented off-fl avour in the eggs (Ajuyah et al., 1993). Vitamin E was demonstrated … Read more
Santan (coconut milk) is rich in fat and its consumption has been associated with increased plasma low-density lipoprotein cholesterol levels (LDL) and greater risk of arterial thrombosis due to its high contents of short chain saturated fatty acids such as lauric (C12:0) and myristic (C14:0). Therefore, the consumption of santan is discouraged. Palm-based santan has … Read more
Brick spread is widely used in the catering and retail sectors (Figure 1). The applications of this product are for spreading on bread and to stir fry vegetables, rice, seafood, meat and eggs. Brick spread replaces the function of butter in shallow frying application. Brick spread in shallow frying will act to transfer the buttery … Read more
