TT No. 195: Anticrystallizer in palm olein

Palm olein is the preferred oil for cooking and frying because it has good oxidative stability. However, it tends to crystallize and becomes cloudy in cold weather in temperate countries. In these countries, even palm super olein clouds at very low temperature. In Malaysia and other tropical countries, there is no problem with clouding as … Read more

TT No. 194: Novel oil compositions

It is interesting to note that natural oils and fats have saturated:monounsaturated:polyunsaturated fatty acid ratios which vary tremendously from one extreme to another as shown in Table 1. When keeping the monounsaturation level at 1.0, highly unsaturated oils are tilted towards the polyunsaturated, while highly saturated oils such as coconut and palm kernel oils are … Read more

TT No. 193: Value-added products from palm pressed fibres

Palm-pressed fibre is a by-product produced by palm oil mill after screw-pressing of palm fruits during the production of crude palm oil (CPO). The palm-pressed fibre generated is normally burnt as solid fuel to self-supply steam and electricity required for the operation of the mill. However, the residual oil in the pressed fibre contains high … Read more

TT No. 192: Used frying oil : recovery and applications

Vegetable oils including palm oil exhibit poor quality in terms of stability and high free fatty acids (FFA) content after exhaustive frying process. During frying, the oil darkens in the presence of phenolic minor components and is no longer good for health when polar compounds reach up to 25%-27%. These used frying oils are usually … Read more

TT No. 191: Rapid moisture determination for palm pressed fibres

Moisture content in palm products is an important process control parameter in a palm oil mill. The current standard procedure of determining the moisture content of palm oil samples is to weigh a sample, heat it in an oven at 103o C to drive off the moisture and reweigh. The loss in weight is presumed … Read more
