CALCULATIONS
PERCENTAGE OIL YEILD DURING OIL EXTRACTION
% yield = Total mass of oil extracted
Total mass of palm kernel fried
Mass of oil extracted = 630g
Mass of palm kernel fried = 1400g.
Therefore,
%yield = 45%
% FREE FATTY ACID CONTENT OF THE CRUDE PALM KERNEL OIL(PKO)
Where a = volume of sodium hydroxide (NaOH) used in titration.
W= the weight of the oil used as sample.
2= lauric oil acid factor.
From titration, a = 4.3ml
W= 3.105g.
Thus,
PEROXIDE VALUE CALCULATION FOR CRUDE PALM KERNEL OIL(PKO)
Where b = titre value/ the volume of sodium thiosulphate(Na2 SO3) used for titration.
N = molar concentration of the sodium thiosulphate.
W= weight of the oil sample used.
And
b= 12ml
N= 0.2M
W= 3.20g.
