Development of antimicrobial medical cotton fabrics using synthesized nanoemulsion of reactive cyclodextrin hosted coconut oil inclusion complex

Reactive cyclodextrin (RCD) based nanoemulsion and loaded with coconut oil in presence of Tween 80 emulsifying agent for development of antimicrobial medical cotton fabrics is the subject of current research. RCD based nanoemulsion was prepared at different stirring duration, viz, 2, 4, 6 and 24 h in presence of Tween 80. This was done in order to induce varieties in size and morphology of the nanoemulsion. The coconut oil encapsulated RCD based nanocomposite was precipitated as powder using centrifugation technique for 60 min at 4500 rpm and the resulted powder was investigated using TEM and SEM techniques. The images that provided by these techniques confirmed the nano-sized scale of the coconut oil loaded RCD nanocomposite. In addition, the entrapment efficiency of coconut oil loaded RCD based nanoemulsion after centrifugation was calculated and was found to more than 93 %; this is a proof for the successful inclusion of the coconut oil inside the cavity of RCD molecules. Moreover, the obtained RCD based nanoemulsions were applied to bleached cotton fabrics as per the pad-dry-cure method. The as treated cotton fabrics were monitored for nitrogen content, add-on, mechanical properties and morphology vis-a-vis those similarly treated fabrics but using the as prepared microemulsion of RCD loaded with coconut oil in absence of Tween 80. The morphological structure of cotton fabrics treated with the nanoemulsion in question was also examined using SEM technique. Moreover, the biological activity of the nanoemulsion finished fabrics before and after being submitted to 20 washing cycles was investigated against different types of bacteria and fungi as per the inhibition zone method. Results obtained signify: (i) deposition on the fabric of coconut oil loaded RCD nanoemulsion; (ii) the add-on of the nanoemulsion on the surface of cotton fabric is a manifestation of the stirring duration, proofing the formation of ultrafine oil nanoemulsion which penetrates the fabric surface; (iii) the finished fabrics display antimicrobial activity with clear excellent inhibition zone even after 20 washing cycles, indicating the protection of these fabrics for human beings from harmful microbes. In conclusion, the cotton fabrics treated with nanoemulsion of RCD loaded coconut oil is considered as an effective super antimicrobial medical textile against pathogenic microorganisms of both bacteria and fungus species.

Effects of a Fish Oil Rich in Docosahexaenoic Acid on Cardiometabolic Risk Factors and Oxidative Stress in Healthy Rats

Omega-3 polyunsaturated fatty acids are associated with a lower risk of cardiometabolic diseases. However, docosahexaenoic acid (DHA) is easily oxidized, leading to cellular damage. The present study examined the effects of an increased concentration of DHA in fish oil (80% of total fatty acids) on cardiometabolic risk factors and oxidative stress compared to coconut oil, soybean oil, and fish oil containing eicosapentaenoic acid (EPA) and DHA in a balanced ratio. Forty healthy male Sprague–Dawley rats were supplemented with corresponding oil for 10 weeks. Supplementation with the fish oil containing 80% DHA decreased plasma fat, plasma total cholesterol and muscle fat compared to the coconut oil and the soybean oil. Increasing concentrations of DHA induced incorporation of DHA and EPA in cell membranes and tissues along with a decrease in ω-6 arachidonic acid. The increase in DHA promoted lipid peroxidation, protein carbonylation and antioxidant response. Taken together, the increased concentration of DHA in fish oil reduced fat accumulation compared to the coconut oil and the soybean oil. This benefit was accompanied by high lipid peroxidation and subsequent protein carbonylation in plasma and in liver. In our healthy framework, the slightly higher carbonylation found after receiving fish oil containing 80% DHA might be a protecting mechanism, which fit with the general improvement of antioxidant defense observed in those rats.     

Yeast breads containing oils varied in fatty acid composition: Effects on sensory panel acceptability

Choice of the shortening ingredient in bread products has functionality effects and health implications. Little information is available on effects of various shortening ingredients on palatability and acceptability. The objective of the current study was to compare the acceptability of yeast-leavened wheat breads containing shortenings containing predominantly saturated fatty acids (coconut oil), monounsaturated fatty acids (canola oil) or unsaturated fatty acids (unhydrogenated soybean oil). Breads were prepared using a standardized formula and method. These were evaluated by a 16-member, semi-trained panel for color, flavor, texture, tenderness and overall acceptability using a seven-point hedonic scale. No significant differences in color and texture were defined; however, canola oil bread was judged significantly superior to soybean oil bread in flavor, and both of these breads were found to be significantly superior to coconut oil bread in flavor, tenderness, and overall acceptability.     

Coconut kernel protein modifies the effect of coconut oil on serum lipids

Feeding coconut kernel along with coconut oil in human volunteers has been found to reduce serum total and LDL cholesterol when compared to feeding coconut oil alone. This effect of the kernel was also observed in rats. Since many plant proteins have been reported to exert a cholesterol lowering effect, a study was carried out on the effect of isolated kernel protein in rats. Feeding kernel protein resulted in lower levels of cholesterol, phospholipids and triglycerides in the serum and most tissues when compared to casein fed animals. Rats fed kernel protein had (1) increased hepatic degradation of cholesterol to bile acids, (2) increased hepatic cholesterol biosynthesis, and (3) decreased esterification of free cholesterol. In the intestine, however, cholesterogenesis was decreased. The kernel protein also caused decreased lipogenesis in the liver and intestine. This beneficial effect of the kernel protein is attributed to its very low lysine/arginine ratio 2.13% lysine and 24.5% arginine.
