Effect of ozone addition on virgin coconut oil using changes in light transmission polarization

Abstract

Today, the investigation of ozonized cooking oil becomes a very interesting research development topic, in addition to the study of ozone interactions in liquids and its application to the treatment of skin cancer. This research was conducted to determine the change in the transmission polarization angle in Virgin Coconut Oil (VCO) that was interacted with ozone. Laser pointers with a wavelength of 650 nm were used as light sources. The polarization changes are proportional to the duration of ozonation, and the longer duration is accompanied by more accumulative numbers of free fatty acids. The interaction is considered to be quite effective, with supposedly one ozone molecule interacting with one symmetric triglyceride molecule to become a new asymmetric triglyceride molecule in the interaction. This interaction increases the active optical properties of VCO samples. In contrast to the latest sophisticated spectroscopic methods, the polarization method seems simpler by simply measuring the change in polarization of light. With the ability of the polarization method that can distinguish the characteristics of cooking oil before and after experiencing treatment, this method has a large chance to be developed in subsequent studies relating to polarization as an indicator of the interaction of light with the material in the field of biophysics and other related fields.
