South Africa’s Initial Experience In Using Palm Olein Blends For The Manufacture of Pre-Fried French Fries

South Africa produces considerable quantities of oils and fats with total production averaging 480 000 t yr-1. Sunflower oil is the major oil with production at around 330 000 t annually. This is insufficient for the domestic consumption which in 2002 was around a million tonnes putting the per capita consumption at 23 kg yr-1. Quite large quantities of oils/fats have, therefore, to be imported. Only about 60 000 t oils/fats are exported from South Africa annually, about half of which comprises sunflower oil.

A mammalian diploid cell (a cell having two complete sets of chromosomes) expresses ~2 x 10^4 mRNAs (messenger ribonucleic acids) from the genome of 1.40 x 10^5 genes. This well established observation implies the existence of complex mechanisms that selectively transcribe the cell-specific genes within the nucleus and coordinate the transcriptional processes with dynamic events […]
