“…Signals between 4 and 5 ppm reflect the nature of β‐anomeric linkages. The IFPG bonds (such as soluble portion) are often β‐anomeric 19 . According to reports, the presence of rhamnose in the soluble fraction and whole gum, which has a position in the branch structure or at the end, is identical 46 .…”

BackgroundIn the present study, the insoluble fraction of Persian gum (IFPG) was modified with octenyl succinic anhydride (OSA) and its various properties were assessed. In addition, the effect of OSA‐IFPG was investigated on the rheological and textural properties of dairy cream.ResultsSuitable conditions for achieving a degree of substitution (DS) of 0.023 was found at pH 9, IFPG concentration 4 wt.%, OSA concentration 10 wt.%, temperature of 40°C, within 120 minutes. The carbonyl group attachment in 0SA‐IFPG was also confirmed via FTIR and H NMR spectroscopy . While X‐ray diffraction test indicated no significant changes in the structure of the IFPG after modification with OSA, esterification increased the negative charge density, decreased thermal decomposition temperature, and increased the emulsifying capacity to 100%, which was obtained for the first time. The use of OSA‐modified IFPG in creams augmented the complex viscosity, loss, and storage modulus while also demonstrating the creation of a pseudo‐gel network. The hardness and adhesiveness of the texture increased, which can be explained by the formation of a compact structure and reduced particle size.ConclusionOverall, OSA‐IFPG with hydrophilic and hydrophobic sections may function as an emulsifier and be recommended as a safe source of hydrocolloids for emulsion stability. It can also provide a positive physical structure when added to dairy cream, even if the fat concentration is lower than usual.This article is protected by copyright. All rights reserved.

“…77 Moreover, above 232 °C the second and most remarkable weight loss of FG occurred due to polysaccharide degradation, which led to an 85.0% decomposition rate at 800 °C. 18,78 Furthermore, the second drop in the weight of FeCl 3 •6H 2 O commenced at 200 °C and this was ascribed to the dehydrochlorination process. 79 The weight loss stages of FG-Fe and Gel were similar to that of FG due to being the major component of the hydrogels, and their weight losses at 800 °C were 77.3% and 83.4%, respectively.…”

“…Also, a blend of MC and pluronic has been fabricated for sustained drug delivery used in bone tissue engineering (Rangabhatla et al 2016). Persian Gum (PG), also known as Angum, Farsi, and Zedo gum is a novel source of polysaccharide that exudes from the mountain almond trees (Amygdalus scoparia Spach) grown mainly in the Zagros forests of Fars province in Iran (Abbasi 2019). In ancient medicine, PG has been used as a treatment for swollen joints, parasitic diseases, toothaches and coughs, and today it has gained signi cant attention for various food and pharmaceutical applications (Dabestani et al 2018).…”

Besides, its compatibility with other macromolecules (Abbasi 2019) and its bene cial effects in improving stability and rheological properties have been studied (Dabestani et al 2018). Nevertheless, according to our knowledge, the application of PG in thermosensitive hydrogel systems for bone tissue engineering is novel and its combination with MC has not been investigated so far.…”

In-situ forming hydrogels have gained noticeable attention to encapsulate osteogenic agents and regenerate irregular-shape bone defects. In this study, a novel thermosensitive hydrogel based on blended methylcellulose (MC) with Persian gum (PG) was fabricated and enriched with taxifolin (TAX) loaded halloysite nanotubes (HNTs) to enhance mechanical and biological characteristics of the hydrogel in bone tissue engineering. The injectability, mechanical and rheological tests were performed for different hydrogel formulations containing 0.25-1.5 w/v% PG and 1-7 w/v% HNTs. Also, to evaluate the impact of PG and HNTs on hydrogel behavior, the degradation rate and swelling degree of hydrogels were assessed. The optimized MC/PG/HNTs hydrogel containing 1% PG and 3% HNTs (MC/PG-1/HNTs 3%) was easily injectable and gelled rapidly at physiological temperature, while it had the highest mechanical strength due to the existence of PG and HNTs. In vitro release study of TAX from this system also revealed more sustained release compared to HNTs-TAX nanoparticles. Furthermore, the interaction of cells with hydrogel and osteo-conductivity was studied using osteoblast-like cells (MG-63). Results showed higher cell adhesion, proliferation, and gene expression for MC/PG-1/HNTs-TAX hydrogel compared to MC/PG-1 and MC/PG-1/HNTs 3% possibly due to the synergic effect of HNTs and TAX. In addition, Alizarin Red S staining and alkaline phosphatase measurements indicated that the existence of HNTs-TAX promoted osteogenic differentiation. Eventually, animal studies on the femoral defects indicated improved remedy when using the MC/PG-1/HNTs-TAX hydrogel carrying MG-63 cells.'Al 2 Si 2 O 5 (OH) 4 •nH2O' are safe, biocompatible and cheap aluminosilicate clay, which have been used as a
