Nano-encapsulation of fish oil and garlic essential oil by a novel composition of wall material: Persian gum-chitosan

Nanoencapsulation of Mandarin Essential Oil: Fabrication, Characterization, and Storage Stability

“…Meanwhile, the NCEO-MD formulation had the lowest relative crystallinity ( Figure 2 ). These values were higher than those reported by Mohammed et al [ 28 ] (21.76–35.13%), but lower than those reported by Raeisi et al [ 46 ] (42.7–48.8%). Crystallinity influences the rehydration properties of nanocapsules, such as wettability and solubility.…”

“…The particle size and PDI of reconstituted nanocapsules are critical parameters to consider because they are connected to release, stability, and compound distribution [ 45 ]. Raeisi et al [ 46 ] confirmed that the capsules with PDI values close to 0.4 are appropriate for the food industry. Table 3 shows that the particle size of reconstituted NCEO ranged from 427.35 nm to 782.09 nm, while the PDI values ranged from 0.26 to 0.47.…”

Effect of gamma irradiation on physico‐mechanical and structural properties of active Farsi gum‐CMC films containingZiziphora clinopodioidesessential oil and lignocellulose nanofibers for meat packaging

“…The FTIR peaks of neat CMC film are seen at 2,900 to 3,700 cm −1 (stretching vibrations of –OH groups as well as intermolecular and intramolecular hydrogen bonds), 2,826.71 and 1,635.69 cm −1 (stretching vibrations of C–H and carboxylic groups), 1,472.83 and 1,322.72 cm −1 (–CH 2 scissoring and –OH bending vibrations), and 1,000 to 1,200 cm −1 (–C–O– stretching vibration on polysaccharide skeleton) (Khezrian & Shahbazi, 2018). In the FTIR of FG, the following peaks were recorded: 3,000 to 3,500 cm −1 (stretching vibration of –OH groups), 2,945 cm −1 (asymmetrical stretching vibration of –CH 2 ‐functional groups), 2,877 cm −1 (symmetrical stretching vibration of –CH 2 ‐functional groups), 1,620.56 cm −1 (asymmetrical stretching of carboxylate groups and –OH bending intramolecular vibrations), 1,395.32 cm −1 (bending vibration of –CH 3 ), 1,024.68 cm −1 (stretching vibrations of C‐O and C–C), and 700 to 1,000 cm −1 (stretching vibration of C–H) (Raeisi, Ojagh, Quek, Pourashouri, & Salaün, 2019; Rezaei, Nasirpour, & Tavanai, 2016). In the FTIR of FG‐CMC, the identified peak band around 3,000 to 3,500 cm −1 broadened and shifted to lower wavelength probably due to the hydrogen bonding formation between –OH groups of CMC and carboxylate groups of FG.…”

A novel clean biopolymer-based additive to improve mechanical and microstructural properties of clayey soil

“…Persian gum is a novel source of hydrocolloid biopolymers categorized as plant exudates gums and obtained from branches of wild almond (Amygdalus scoparia) plants in arid and semi-arid regions of Zagros forest in Fars province, Iran (Dabestani and Yeganehzad 2019). This polysaccharide has found wide applications in various industries such as food, pharmacy and textile (Abbasi and Rahimi 2015; Chahibakhsh et al 2019;Raeisi et al 2019) due to its comparable effects with commonly used hydrocolloids (Amini Rastabi and Nasirpour 2017; Dabestani et al 2018;Raou et al 2019). In a recent paper, Ghasemzadeh and Modiri (Ghasemzadeh and Modiri 2020) introduced Persian gum as a novel kind of hydrocolloid soil stabilizers.…”
