Ozonation Process

Background: Pediculosis is an infestation of lice affecting mostly children and spreads by direct contact with the hair of someone infected. Although topical application of a pediculicide such as permethrin shampoo is the most common cure for head lice, the addition of alternative treatments is necessary due to permethrin resistance and some safety concerns, including irritation, burning sensation, tingling, and breathing problems. Recent studies have indicated that ozone, which is an allotropic form of oxygen, may have anti-pediculosis effects. Objective: This study focused on the evaluation of an ozonated olive oil topical lotion for the treatment of pediculosis and the comparison of its effects with permethrin shampoo. Methods: 121 patients with proven head pediculosis were divided into two groups. They were treated with either topical ozonated olive oil lotion or permethrin shampoo for one week. Results: It was shown that the ozonation process enormously improved the physico-chemical properties of olive oil. Specifically, acid and peroxide values increased 60 fold and 200 fold, respectively, while there was a sharp decline for the iodine index (81.8±1.28 to 0 g iodine per 100 g). Additionally, all patients who received the ozonated olive oil lotion were entirely cured after one week of treatment, while those who were treated with permethrin, required to receive more. Statistical analysis of the data also proved this claim. Conclusion: The prepared lotion has shown significant effects in controlling head lice. Thus, it can be prescribed as an effective anti-pediculosis medicine which is biocompatible and has high potential.

This review supplies a report on fresh advances in the field of silk fibroin (SF) biopolymer and its blends with biopolymers as new biomaterials. The review also includes a subsection about silk fibroin mixtures with synthetic polymers. Silk fibroin is commonly used to receive biomaterials. However, the materials based on pure polymer present low mechanical parameters, and high enzymatic degradation rate. These properties can be problematic for tissue engineering applications. An increased interest in two- and three-component mixtures and chemically cross-linked materials has been observed due to their improved physico-chemical properties. These materials can be attractive and desirable for both academic, and, industrial attention because they expose improvements in properties required in the biomedical field. The structure, forms, methods of preparation, and some physico-chemical properties of silk fibroin are discussed in this review. Detailed examples are also given from scientific reports and practical experiments. The most common biopolymers: collagen (Coll), chitosan (CTS), alginate (AL), and hyaluronic acid (HA) are discussed as components of silk fibroin-based mixtures. Examples of binary and ternary mixtures, composites with the addition of magnetic particles, hydroxyapatite or titanium dioxide are also included and given. Additionally, the advantages and disadvantages of chemical, physical, and enzymatic cross-linking were demonstrated.

Ozonation Process

Cocozone Oil (CCO) is one of the ozonated oils, obtained by the ozonation process of Virgin Coconut Oil (VCO), that can be used as a material for skin care products. The purpose of this study was to determine: (1) the optimum time and ozone dose for CCO synthesis from VCO using ozonation; (2) the changes in physico-chemical properties of the oil; (3) the change in saturated-unsaturated fatty acids content and the existence any new substances in the CCO. The ozonation of VCO was carried out for 25 hours, with monitoring at the intervals of 4, 8, 12, 16, 20 and 25 hours, at a constant temperature (25 °C) with an ozone flow of 0.25 g/hr. From this study it can be concluded that: (1) The optimal time or dose of ozone required for the synthesis of CCO from VCO through the ozonation process was 25 hours or equivalent to 0.0208 gr O3/ml VCO, (2) Physico-chemical characteristics of the CCO produced: resulting acid value (AV) was 2.71 mg/gram i.e. an increase of 630%; the peroxide value (PV) obtained was 238,77 mgrek/kg i.e. increase  of 3,453 %; the Iodine value (IV) was 0 (zero) i.e. a decrease of 100%; and, the viscosity was 13.30 centipoice i.e. it rose 116%; (3) the total content of saturated fatty acid increased by 3.34%  whereas the unsaturated fatty acid decreased by 98.83; and based on the analysis results of 13C and 1H NMR spectra, the resultant CCO contains a new substance, that is aldehydes.

This study was aimed at evaluating the physico-chemical properties, antifungal and anti-sprouting efficacy of Moringa oleifera and Sesame indicum seed oil extracts. Physico-chemical parameters were determined and compared for both oils. There was significant (p < 0.05) difference observed between the refractive values (1.4570 and 1.4633), free fatty acid (FFA) (2.04 and 3.21 mg KOHg-1), acid values (6.08 and 6.43 mg KOHg-1), pH values (4.55 and 5.33), saponification values (210.75 and 215.57 mg of KOHg-1), peroxide values (5.40 and 5.80 meqO2/kg), specific gravity (0.8897 to 0.9161 g/cm3) and yield (8.25% and 32.02%) for cold press extracts of Sesame and Moringa seed oils respectively. In vitro antifungal efficacy of both oils (M. oleifera and S. indicum) against Aspergillus niger shows a range of 43.63% to 58.18% inhibition. No anti-sprouting effect was recorded across all concentrations tested for the two oils. However, the antifungal potential of both seed oil extracts (Moringa and Sesame) exhibited moderate inhibitory properties with the highest percentage inhibition at 48 hrs.

The quality and stability of palm kernel oil (PKO) and cottonseed oil (CTSO) as affected by bleaching using modified oyster shell powder (OSP) and periwinkle shell powder (PSP) were evaluated by analysing their physicochemical properties. The two adsorbents potential was improved on by modification using 5 M HCl and H2SO4. The determinations of the parameters were carried out by titration, while the refractive index was determined using a refractometer. The results indicate that the saponification values (SV) of PKO and CTSO increase after bleaching. However, the result further shows that the peroxide values (PV) of bleached PKO using OSP and PSP modified with 5 M HCl decreased (17.49±0.01 and 20.04±0.08 respectively) and also the iodine values decreased (3.15±0.13 and 3.41±0.02 respectively). The same decrease in PV and IV values is observed in PKO bleached using 5 M H2SO4. The values of PV for OSP and PSP are 4.99±0.005 and 12.77±0.77 respectively while the IV values for OSP and PSP are1.85±0.01 and 12.53±0.09 respectively. Also, 5 M HCl and H2SO4 modified OSP and PSP reduced the IV content in CTSO. (5 M HCl OSP and PSP are; 3.15±0.13 and 3.41±0.02 respectively while 5 M H2SO4 OSP and PSP values are; 3.33±0.04 and 3.13±0.06 respectively). The study revealed that the bleaching through the use of OSP and PSP influenced the components and properties of the PKO and CTSO, improved on their qualities and therefore, the adsorbents can serve as alternatives to the costly adsorbents available in the markets.

The objective of this paper was to study the effect of milk fat substitution by (W1/O/W2) multiple emulsions based on olive oil in comparison with full and low-fat milks on milk behavior during rennet coagulation. Therefore, based on the turbidimetric and conductivimetric methods, a follow up of enzymatic coagulation is realized. Drainage of renneted gels was followed by syneresis study and cheese yield. The comparison between the coagulation aptitude of low fat milk and milk-olive oil emulsion showed that the hydrolysis phase extended up to 35 minutes for full fat milk and up to 38 minutes for milk-olive oil emulsion. The transition phase solid/gel was shorter in the case of the whole milk. The reticulation phase was shorter in the case of milk-olive oil emulsion. The milk conductivity depended on the milk richness in fat content. Milk-olive oil emulsion showed the lowest cheese-making yield compared to its full and low-fat counterpart.

Olive oil, especially extra virgin olive oil, gained popularity recently due to its beneficial effects toward human health. Olive oil contained high amounts of monounsaturated fatty acids, especially oleic acid (C18:1) and some minor components such as tyrosol and hydroxytyrosol which are important to human health. Olive oils have been reported to have antioxidant in vitro and in vivo. This article reviewed some physico-chemical properties and antioxidant activities of olive oil either in vitro or in vivo. Olive oil was evaluated in vitro using radical scavenging activities, ferric reducing antioxidant power (FRAP), metal chelating power, beta-carotene bleaching, linoleic acid-ferric thiocyanate method. In vivo, the antioxidant activities of olive oil were evaluated using glutathione Stransferase, catalase, and superoxide dismutase. Phenolics compounds present in olive oil contribute to antioxidant activities, therefore, olive oil is potential to be used as a food supplement.
