PKE is the residual meal derived from the palm oil extraction process. The oil in PKE is highly stablemeaning that PKE has a long shelf-life if stored correctly.
PKE also contains almost no starch, so unlike grain-based feeds, will not cause problems such as acidosis.
Best of all, PKE is economically priced.
VENDOR DECLARATION PALM KERNEL EXPELLER MEAL
Organic Products Pty Ltd hereby makes this declaration subject to the conditions and procedures stated and warranted by our Papua New Guinea supplier in their Cattle Care Australia Accreditation correspondence dated 11th August and 22nd December for Palm Kernel Expeller Meal (PKE) sold to Organic Products Pty Ltd loaded in containers ex PNG.
The PKE is in no way treated by Organic Products Pty Ltd after receival into its care. The Palm Kernel Meal is passed from the vendors care into the clients care in the same condition as the PKE is received from our PNG supplier. Organic Products Pty Ltd to the best of its knowledge believes that PKE supplied to its clients is fit for the intended use of feeding livestock at the time of transfer of ownership of the feedstuff. PKE is derived from the Oil Palm (Elaeis guineensis Jac g.), which our supplier confirms has not been genetically modified.
The Papua New Guinea supplier states in their Cattle Care Accreditation correspondence for PKE:
“We use predominantly nitrogen based fertilizers in the form of ammonium chloride or sulphate. Small amounts of magnesium and potassium are also applied. Rates are usually of the order of 250-300 kgs of fertilizer per hectare. There are no fungicides sprayed on any of our palms. There are no insecticides of any nature sprayed on our palms, however we do trunk inject approximately 10mls of monocophos into the palm to control leaf-eating grasshopper
This treatment is sporadic and occurs on less than 1% of our area. Most of our plantations are bounded by either primary rainforest or smallholder oil palm blocks. In the case of smallholders there is little or no chemical usage and what fertilisers are applied would be the same as above but only 50% of the application rate.
The palm oil milling process is purely mechanical and is steam driven, with no chemical extraction process. The extraction of oil from the kernels is equally a mechanical one, where the kernels are hammer milled and then subjected to a screw pressing. The resulting PKE is therefore a byproduct of a non chemical process from start to finish. Our main products are sold for consumption into high quality cooking oils and edible products. The buyers in Europe subject all their raw materials to intensive screening for impurities and harmful products. It is therefore reasonable to assume that as the PKE is a byproduct of the same process it will be entirely safe from contamination as it leaves our factory”.
The raw material, the fresh fruit bunches (FFB) of the oil palm tree, is sterilized for up to 110 minutes at a temperature of 140o C. This process is two-fold; it stops the biological degradation of the fruit and also loosens the fruitlets from the bunch to aid in downstream processing.
The fruitlets are stripped from the bunch mechanically, and conveyed to a digester where they are stored for approximately 30 minutes at 97o C. The subsequent mash from the digester enters a screw press and the crude palm oil is extracted from it. The fibre and nuts that are left behind from the extraction process are separated from each other and the nuts are conveyed to a drying hopper. From here they enter a ripple mill, which cracks the shell of the nut to release the palm kernel. The shell and kernel are separated from each other mechanically and the kernel is conveyed to a drier. Here the kernel moisture is reduced to approximately 7% to aid the kernel oil extraction process.
The dried kernels are then conveyed to a hammer mill where they are pulverized before entering the first stage cooker. The pulverization of the kernel generates a lot of heat, so much so that little or no steam is used in the cooker. The pulverized kernel from the first stage cooker is transferred to the first stage expeller where a percentage of the palm kernel oil is extracted. The remaining expeller cake is conveyed to a second stage cooker and expeller where most, but not all, of the remaining oil is extracted. The expeller cake from both first and second stage expellers exits at approximately 77o C. The residual expeller cake is cooled and then transferred straight into clean containers ready for export.
