What are palm kernel cakes?
Palm kernels produced during the milling process of palm fruits contain approximately 50% oil that can be extracted commercially via two methods, i.e. mechanical expression and solvent extraction. Palm kernel cake is the by-product of the oil extraction process. The main use of this product is as an ingredient for compounding animal feed.
It has high fibre content and thus is usually used in foods for ruminants such as cattle. However palm kernel cake is also a good source of phytin, which is a precursor of phytic acid and inositol. The latter compounds have many industrial applications. PORIM has patented the extraction process for phytin and is working closely with the local industry to develop further into this new area.
