REVIEW OF A SIMPLE POWERFUL POLARIZER FOR TESTING OF EDIBLE OIL QUALITY
Abstract: In this paper, we
have shown that a simple pair of polarizer can be used to measure natural
optical activity in total complex oil (vegetable oil and fats). A similar
concept with quantum physics has been discussed to describe briefly the
probability in finding a particle within certain region with the change of
polarization due to the interaction light with saturated fatty acids. The light
source was fluorescence lamp and the experimental condition was kept stable,
i.e. constant temperature and constant humidity. The angle of polarization was
measured repeatedly until 50 times. Our relative uncertainty measurement has been
obtained up to 5% and this is obviously clear to be able to differentiate
various different quality of oil. More important result is that ordinary light
polarization can be used as powerful test to show various quality level of oils
better than recent standard methods. A good prospect has also been obtained for
halal level testing. It is found that average value of polarization in lard
(pig oil) is relatively higher than the others.
