“…Since many of the unsaturations on indoor surfaces come from cooking and skin oils, we looked first to the vegetable oil ozonation literature to estimate the OPX yields. Vinet et al 69 measured the peroxide index and ozone “applied” for various vegetable oils that were ozonated. The peroxide index (PI) is a measure of the concentration of peroxidic compounds in solution.…”

“…The reaction of ozone with oil or ozonation of oil containing unsaturated fatty acids leads to the formation of oxygenated compounds such as hydroperoxides, ozonides, and aldehydes, which reduce bacterial infections in wounds. The ozonation process is widely applied to various types of oil, both for medical, energy and other purposes, such as kapuk oil [9], rice bran oil [10], sunflower oil [11][12][13], olive oil [14][15][16][17][18][19][20], vegetable oil [21][22], palm seed oil [23], waste cooking oil [24] and bulk frying oil [25].…”

Oil is one of the most popular media for the ozonation process compared to other media such as water or saline methods or direct exposure to blood. Ozonated oil has an advantage over other ozone therapy methods because ozonated oil has an antiseptic activity that is several hundred times higher than ozonated saline. Sumbawa oil is one of the local wisdom products of the Sumbawa tribal community, which is generally used as medicine or massage therapy to heal injuries such as broken bones, tendonitis, bruises, back pain and treatment of various skin wounds. An ozonation process can be carried out to increase the ability of Sumbawa oil to regenerate skin and repair tissue. Ozonation uses a Double Dielectric Barrier Discharge (DDBD) plasma reactor. The DDBD Plasma Reactor is a reactor that can produce ozone gas with very high purity. Pure ozone gas is very well applied in the medical world. This research aims to increase the peroxide levels in Sumbawa oil by ozonation using a Double Dielectric Barrier Discharge (DDBD) Plasma reactor. The flow rates used were 0.1 L/minute, 0.4 L/minute and 0.7 L/minute for 1 hour, 3 hours and 5 hours. The results showed that the peroxide value increased with increasing oxygen flow rate and ozonation time. The highest peroxide value was obtained at a flow rate of 0.7 L/minute for 5 hours, namely 332.03 mg Eq/kg Sumbawa oil. Increased by 282.71 mg Eq/kg; the peroxide figure for Sumbawa oil without ozonation was 49.32 mg Eq/kg.

“…Near infrared spectroscopy (NIRS) has also been reported as a powerful technique that allows to directly correlate spectral changes with the chemical alteration of lipids. [14,15] NIRS is an analysis method that uses the near infrared (NIR) region of the electromagnetic spectrum between 780 and 2500 nm, corre-sponding to overtone and combination bands. [16] This method has already been applied to in situ monitoring of lipid oxidation in O/W emulsions (using a fiber optic probe), and the conjugated diene values have been correlated to the recorded NIR spectra for the first 7 days of aging at 25 • C. [9] The originality of the present study is to develop a noninvasive method using NIRS to assess the oxidative state of a multiple emulsion during its storage.…”

Lipid oxidation has an impact on the quality and properties of fat‐containing products that are commonly produced by cosmetics or coatings industries. In this study, a water‐in‐oil‐in‐water emulsion (48% w/w of pre‐polymerized linseed oil stabilized with alkylpolyglucoside) was subjected to oxidation under accelerated aging conditions at 50°C over 15 days. After fat extraction from emulsion, peroxide, and p‐anisidine values were measured using standardized methods. The application of near infrared spectroscopy (NIRS) in conjunction with chemometrics was investigated to assess the quality parameters of emulsions under accelerated aging within closed flasks. Significant variations were observed across the following spectral regions: 7541–5948, 5739–3657, and 3645–3637 cm−1. Partial least squares regression discriminant analysis, possibly combined with multiplicative scattering correction preprocessing, proved to be a powerful method to classify the emulsions according to two oxidation levels defined by periods A and B. The performances of the prediction model were characterized by a precision of 85%, a predictive value of period A of 98%, a sensitivity of 99%, a specificity of 81%, and an accuracy of 90%. Thus, we demonstrate that NIRS is a suitable analytical method to discriminate emulsions according to their aging behavior.Practical Applications: The PLS‐DA method coupled to near infrared spectroscopy analyses is adapted to assess the chemical degradations of vegetable oil–based emulsions due to lipid oxidation. This tool is interesting for at‐line or off‐line monitoring of emulsions during their storage. As it is a fast and nondestructive method, the quality control of a formulation stored in a closed glass container is facilitated. This method could also be used to determine the effectiveness of an antioxidant or a drier in emulsions, respectively, prepared for cosmetics and coatings.
