Microencapsulation is one of the techniques to prepare the functional textiles. In this paper the essential cinnamon oil loaded microcapsules were prepared by solvent evaporation method. In the microencapsulation process, the core - shell ratio was changed by altering the cinnamon oil content in four levels of 0.15, 0.25, 0.35 and 0.45 g while the other components remained unchanged. The microcapsule characteristics including shape and morphology, size and size distribution, microencapsulation efficiency in dependence on the core-shell ratio were investigated. The antimicrobial capacity and the fragrance durability of interlock knitted fabric coated with the elaborated microcapsules were evaluated. The results showed that cinnamon oil was microencapsulated successfully in the spherical microcapsules. When the cinnamon oil content increased, the microcapsule size decreased and the size distribution became broader, the microcapsules were more porous and more aggregate, the fragrance intensity of the fabric treated with microcapsules increased while the activity against E. coli bacteria decreased. According to the results, the microcapsules elaborated with 0.15 g of cinnamon oil was recommended for the treatment of interlock cotton knitted fabric to apply in aroma and antimicrobial textiles.

“…In the Western Balkans, α-pinene was 10.2-29.9% and neryl acetate was 4.1-13.5%; there were lower proportions of γ-curcumene (0-22%) [13,46]. Mediterranean essential oils are characterized by a high content of α-pinene (22%) and lower proportions of γ-curcumene (10%), β-selin (6%), neryl acetate (6%) and β-caryophyllene (5%) [17,47,48].…”

Influence of Harvest Time, Method of Preparation and Method of Distillation on the Qualitative Properties of Organically Grown and Wild Helichrysum italicum Immortelle Essential Oil

et al. 2021

The most important process in immortelle is the extraction of the essential oil by distillation. The chemical properties of the plant depend largely on the cultivation type, climatic conditions and agrotechnical measures. In this work, studies were carried out on organically grown and wild immortelle harvested during the summer (July) and autumn (October) seasons of 2020. Immortelle samples were prepared by drying naturally in two ways: in direct sunlight and in shade. To extract the essential oil, immortelle was distilled in two ways: on an industrial and a laboratory scale. The essential oil was analyzed by gas chromatography to determine the composition and quality of the essential oil. The results of this work showed that the qualitative properties of the essential oil were influenced by the cultivation type, harvesting time, preparation method and distillation method. A higher yield (0.21% ± 0.03) of essential oil was obtained from wild immortelle whereas a better utilization rate (0.38% ± 0.09) of essential oil was obtained from the organically grown immortelle. It was also found that a higher yield of essential oil was obtained from the summer harvest (0.19% ± 0.01) and a higher utilization rate from the autumn harvest (0.33% ± 0.13) with the industrial scale distillation and shade drying. In general, better qualitative properties of immortelle essential oil were obtained from wild immortelle, which was confirmed by a chromatographic analysis and better content of γ-curcumene (16.64% ± 0.30) and neryl acetate (8.15% ± 0.19) and other constituents except α-pinene where organically grown had a higher share (24.27% ± 0.97).

“…An emulsion was made by pouring drop by drop the mixture of coating solution and cantigi extract dispersion to the vehicle phase, stirred at 850 rpm and room temperature for 2.50 hours until all the acetone evaporated. After microcapsules formed, filtered, washed three times with n-hexane, and dried in an oven for 2 hours at 40-50˚C (Song et al, 2022;Brlek et al, 2021;& Yasin et al, 2021). Characterizations of microcapsules include organoleptic (color, odor, shape), recovery, moisture content, entrapment efficiency, drug loading, particle size distribution, bulk and tapped density (Raj et al, 2024;Hibrah et al, 2022;Ditjen Farmalkes, 2022;Song et al, 2022;& Choudhury et al, 2021), and antioxidant activity (Yamauchi et al, 2024).…”

Microencapsulation technology in product development of the food, beverage, and health sectors may provide innovative products with better stability, functionality, and prolonged releases. This study aims to formulate capsule dosage forms containing natural antioxidant microcapsules of Cantigi extract and analyze slow-release profiles. Three microcapsule formulations (F1, F2, and F3) were made by solvent evaporation method using ethyl cellulose coating and characterized for color, odor, particle size, shape, recovery, moisture content, encapsulation efficiency, drug loading, density, and antioxidant activities. Then, three capsule dosage forms (FI, FII, and FIII) of microcapsules of the most potent antioxidant activity, microcrystalline cellulose, and colloidal silicon dioxide. The results showed that the most potent microcapsules were F1, while the most potent capsule dosage forms were FIII. FIII provides the slowest release compared with FI and FII. By analyzing the kinetics of FIII using zero-order, first-order, Higuchi, and Kosmeyer-Peppas models, the release profile of FIII is the best fit with the first-order model kinetics, consistent with a previous study. Moreover, all capsule dosage forms have a biphasic slow-release profile for 60 minutes. The conclusion is that this study can prepare hard-gelatin capsule dosage forms containing natural antioxidant microcapsules of cantigi extract with first-order and biphasic slow-release profiles.
