“…In fact, the bands at 1053 and 1079 cm -1 can be found in the spectrum of cineole ( (Boughendjioua & Boughendjioua, 2017) which correspond to the C-O stretching vibrations of the molecule. Other vibrational bands associated with 1,8-cineole were the symmetrical bending of the methyl CH bonds and -C-O-stretching vibration at 1375 cm −1 (Michelina, Naviglio, Gallo, & Severina, 2019), the C-O-C asymmetric and symmetric stretching at 1217 and 1080 cm −1 , respectively, and the CH2 wagging at 988 cm −1 corresponding to ring deformation vibrations (González-Rivera et al, 2016).…”

Phytochemical-loaded electrospun nanofibers as novel active edible films: Characterization and antibacterial efficiency in cheese slices

et al. 2020

The aim of this work was to develop novel active edible electrospun coatings with antimicrobial properties through the encapsulation of essential oils (EOs) from two widely used spices (Laurus nobilis and Rosmarinus officinalis) for inactivating or reducing spoilage and pathogenic microorganisms. Firstly, EOs from dried leaves of both plants were obtained by hydrodistillation and their composition was analysed by Gas Chromatography-Mass Spectrometry (GC-MS). Interestingly, the main component in both extracts, probably as a consequence of the extraction conditions, was 1,8 cineole. Both EOs showed highest antimicrobial activity against Gram-positive than Gram-negative bacteria. Three different concentrations of the 1,8 cineole-rich EOs were incorporated within a zein matrix through electrospinning and solution properties, encapsulation yield, morphological and thermal stability of the edible coatings developed were evaluated. Then, the antibacterial efficiency of EOszein nanofibers (ZNF) films against Listeria monocytogenes, S. aureus and mesophilic bacteria counts (MBC) was compared with their counterparts prepared by casting (ZF) when applied directly on an inoculated side of cheese slices. EO obtained from Laurus nobilis showed higher antibacterial activity than Rosmarinus officinalis. The antibacterial effectiveness of the active films increased through storage time, showing a significant reduction of  2 logarithm units of L. monocytogenes and S. aureus as compared with the control samples, after 28 days at 4 ºC, using the highest content of 1,8 cineole-rich EOs and in films prepared by means of the electrospinning process. Interestingly, the growth of aerobic mesophilic bacteria was also inhibited in cheese slices coated with EOs-loaded ZNF based films.

This study, referring to the biologically active compounds compatible with textile materials, reveals its influence on human psychophysiological activity. In the COFUND-MANUNET III-AromaTex project, essential oils extracted from lavender, rosemary, mint, thyme were studied and selected to be used for obtaining of aroma-therapeutic effects on textiles, as well as other various effects, such as: skin hydration and anti-acne, revitalizing and reducing stress, improving of microcirculatory blood flow and cellular metabolism. In recent years, electrophysiological studies have been reported worldwide that have shown that different flavors affect spontaneous brain activities and cognitive functions that can be measured by the EEG encephalogram. The presented study contributes to the optimization of formulations which contain essential oils adapted to the conditions of technologies application for deposition and immobilization on textiles, with a particular emphasis on the desired therapeutic effect and the controlled release of essential oils. Aromatherapy application in textile industry led to a series of value-added products that give besides comfort a number of other properties (anti-acne, antimicrobial, fragrance, antiinflammatory sedation, or soothing properties). In recent years, aromatherapeutic textiles were applied in many fields such as food, cosmetics, medicine, tobacco, textiles, leather, papermaking and pharmaceutical industries. The purpose of this chapter was to present the essential oils used in textile finishing, textile supports used for aroma finishing, embedding methods and the controlled release of essential oils.

“…It is widely used in various fields to study composition analysis, product reliability, stability, chemical reaction and dynamic properties [7][8][9]. The analysis is popular in various industries namely pharmaceutical [10,11], forensic [12,13], food [14,15], ceramics [16,17], polymer [18,19], composites [20,21] and semiconductors [22] industries. Further, by thermal analysis, kinetic parameters of thermally simulated reactions can be evaluated which provides a deeper insight in to the mechanism of high energetic compounds [23][24][25][26].…”

Some new pyrimidine derivatives have been synthesized and their decomposition characteristics have been studied by thermogravimetric and differential scanning calorimetric analysis. The thermal stability and some kinetics parameters of decomposition were evaluated from thermograms. It is observed that depending upon the structure, substitutions, thermal stability and decomposition kinetics varies in different compounds.
