Definitions

  • the present invention relates to a process for extracting phytonutrients in palm oil.
  • Crude palm oil consists of 99% glycerides and fatty acids and 1 % of minor components.
  • the minor components commonly found in CPO are namely, carotenes, tocols, tocopherols and tocotrienols, sterols, squalene, coenzyme Qjo, phospholipids and glycolipids.
  • the minor components are also termed as phytonutrients as they have been found to exhibit beneficial health properties such being anti-oxidative and anti cancer.
  • the minor components can be extracted and recovered from the CPO by various methods. However, these methods call for tedious and time consuming procedures. A more rapid process is thus favorable for the extraction and recovery of the palm minor components.
  • the present invention relates to a process for extracting minor components in palm oil.
  • the minor components are known as phytonutrients.
  • the phytonutrients includes carotenes, tocols, tocopherols and tocotrienols, sterols, squalene, coenzyme Qio, phospholipids and glycolipids.
  • the process for extracting phytonutrients includes the steps of: i) mixing the palm oil with alcoholic solution and base catalyst, (ii) heating the mixture obtained from step (i) between 1 to 20 minutes using microwave with frequencies between 200MHz to 300GHz; (iii) cooling the mixture obtained from step (ii) to room temperature; (iv) adding non-polar solvent into the mixture obtained from step (iii) and the mixture is agitated wherein a top layer and bottom layer are formed; (v) subjecting the bottom layer to agitation with non-polar solvent; (vi) repeating step (v) to the bottom layer formed in step (v) and subsequent bottom layers that are formed by adding non-polar solvent and followed by agitation until the upper layer turns pale yellow in color; (vii) drying the upper layers obtained from step (iv), (v) and (vi).
  • the dried portion consists of the minor components.
  • the minor components are such as carotenes, tocols (tocopherols and tocotrienols), sterols and squalene.
  • the alcoholic solution is selected from ethanol, methanol or combination of ethanol and methanol.
  • the base catalyst is selected from potassium hydroxide or sodium hydroxide.
  • the non polar solvent is selected from hexane, heptane or cyclohexane.
  • the present invention relates to a process for extracting minor components in palm oil.
  • the minor components are such as carotenes, tocols, tocopherols and tocotrienols, sterols, squalene, coenzyme Qio, phospholipids and glycolipids.
  • the minor components are known as phytonutrients.
  • Crude palm oil is first mixed with an alcoholic solution and a base catalyst. The mixture is then subjected to reaction under microwave heating for several minutes (between 1-20 minutes). The microwave heating is performed using a frequency range between 200MHz to 300GHz. Crude palm oil is reacted with an alcohol solution and base catalyst, converting the crude palm oil to esters. Minor components, i.e. phytonutrients which remain un-reacted are then extracted from the resultant mixture obtained after the microwave heating through solvent extraction.
  • the mixture After the microwave heating, the mixture is cooled to room temperature and a known amount ( ⁇ 100mL) of non-polar solvent is then added. Upon agitation and left to rest, the mixture forms two layers in which upper layer is kept aside while lower layer is re-extracted with the non polar solvent until it turns into pale yellow in color. The pooled upper layers are then washed with water and dried to zero percent moisture content. The dried portion consists of the said minor components.
  • the alcoholic solution is selected from ethanol, methanol or combination of ethanol and methanol. Any alcoholic solution can be used in the present invention.
  • the base catalyst is selected from potassium hydroxide or sodium hydroxide.
  • the non- polar solvent is selected from hexane, heptane or cyclohexane.
  • Example 1 30mL absolute ethanol and 5mL 50% potassium hydroxide are added to 5.0g crude palm oil in a flat round bottom flask. The mixture is then placed in an 800 watt, 2450 MHz microwave oven. The mixture is then let to react in the microwave for 6 minutes. Thereafter the mixture is left to cool to room temperature. lOOmL hexane is added into the mixture and agitated and left to rest. Two layers are then formed. Upper layer is kept aside while lower layer is again subjected to agitation with hexane. This step is repeated till the upper layer of the re-extracted portion turns pale yellow in color. All the upper layers obtained are then pooled and dried. The dried portion contains the minor components as indicated in Table 1. Table 1 : Minor Components Recovered in the Dried Portion
