Characteristics of vitamin E-loaded nanofibres from dextran

Abstract

In this research, dextran nanofibres were produced as novel carriers for entrapment of vitamin E. Morphological studies indicated that developed fine fibres were in the nano range without spherical beads. Thermal behaviour, chemical structure, and crystalline structure of vitamin E-loaded nanofibres were analysed by differential scanning calorimetry, Fourier transform infrared spectroscopy, and X-ray diffraction which showed that the vitamin was well incorporated within the amorphous structure of fibres without chemical interactions. Nanofibres were used for fortification of cheese. Sensory analysis of the fortified product was performed which showed better acceptability and texture of cheese containing nanofibres in comparison to blank and direct fortified samples. Nanofibres showed the capability of holding water and thus increasing cheese firmness. The release of vitamin E in gastrointestinal media showed that about 14% of vitamin could be released in gastric media and about 30% released in intestinal media. Finally, the results revealed that electrospinning can be used for production of dextran ultrathin fibres to entrap hydrophobic compounds with high potential for design of novel functional foods.

Microencapsulation of vitamin E: Optimization and Characterization of Complex Coacervation Conditions Using Response Surface Methodology

“…FT-IR spectrum of microcapsule produced was obtained. The comments were inferred utilizing the FT-IR analysis results of similar studies [29][30][31]. Specific bands of core material and polymers (vitamin E) used in microencapsulation were observed in the FT-IR spectrum of microcapsules also (Fig.…”

“…In the spectra, we confirmed the presence of -OH and -C-O-C-functional groups in the chromane ring of vitamin E at 1300-1750 cm -1 . FT-IR spectrum showed C=O streching vibration at around 700-1100 cm -1 , C-O formation at 1220 cm -1 , C=C formation at 1780 cm -1 and C-H alkanes group at 2945 cm -1 [31]. According to FT-IR spectrum results, there were electrostatic interactions between gelatin and gum Arabic, and the vitamin E was in the microcapsule.…”

Biobased and Eco-Compatible Beauty Films Coated with Chitin Nanofibrils, Nanolignin and Vitamin E

“…The complex CN-LG and the same complex entrapping Vitamin E showed quite similar spectra, and they showed the described bands of CN and LG (Figure 3). The presence of poly(ethylene glycol) can be responsible for the peak at 840 and 950 cm −1 , characteristic of this polymer [32]. The presence of Vitamin E can be revealed despite its low concentration in the sample (0.2% w/w).…”

Encapsulation of Vitamins A and E as Spray-Dried Additives for the Feed Industry

“…The pure vitamin E spectrum ( Figure 2c) exhibited a wide band at 3473 cm −1 related to the terminal -OH group. Two bands at 2923 and 2864 cm −1 corresponded to asymmetric and symmetric stretching vibrations of -CH 2 -and -CH 3 , respectively [69,70]. The presence of a skeletal phenyl was indicated at 1457 cm −1, and a peak at 1377 cm −1 was attributed to methyl symmetric bending.…”

“…The presence of a skeletal phenyl was indicated at 1457 cm −1, and a peak at 1377 cm −1 was attributed to methyl symmetric bending. The band at 1262 cm −1 was characteristic of -CH 2 groups, and peaks at 1080 and 919 cm −1 were assigned to plane bending of phenyl and trans =CH 2 and C-O stretching [42,69,70]. All these peaks were related to the hydroxyl, methyl, phenyl, and ether functional groups of vitamin E.…”
