Article Abstract
Freeze-dried restructured strawberry blocks (FRSB) have become an increasingly popular product. In this study, the effects of six edible gums (guar gum, gelatin, xanthan gum, pectin, konjac gum, and carrageenan) on the FRSB quality were investigated. For FRSBs, compared with those in untreated samples, the 0.6 % guar gum addition increased texture profile analysis (TPA) hardness, chewiness, and puncture hardness by 29.59%, 174.86%, and 25.34%, respectively; after the 0.6% gelatin addition, the sensory evaluation sourness was reduced by 8.58%, whereas yield, TPA chewiness, and puncture hardness were increased by 3.40%, 28.62%, and 92.12%, respectively; with the 0.9% gelatin addition, the sensory evaluation sourness was reduced by 8.58%; with the 0.9% pectin addition, the yield, TPA hardness, chewiness, and puncture hardness were increased by 4.55%, 5.94%, 77.49%, and 103.62%, respectively. In summary, 0.6-0.9% pectin, gelatin, and guar gum addition are recommended to improve the main qualities of FRSBs.

High-performance hydrogel biomaterials hold considerable promise for advanced wound care. However, the suboptimal mechanical properties of conventional hydrogel materials limit their practical application. In this study, Hyaluronic acid sodium salt (HA), xanthan gum (XG), and N-acryloyl-glycinamide (NAGA) hydrogels with porous structures were successfully fabricated using in-situ extrusion 3D printing technology, and a functionalization strategy involving tea polyphenol (TP) immersion was proposed to enhance material properties through additional hydrogen bonding.

Hydrocolloids are effective in modulating the processing characteristics of native starches, with their efficacy depending on the structural properties of the colloid. This study focused on the effects of different Sanxan gum (SG) concentrations on multiple dimensions of Cyperus esculentus starch (CES), including viscosity, rheology, structural properties, and in vitro digestibility. Viscosity results indicated that SG reduced the peak temperature (70.

For purpose of overcoming the negative impact of high-dose phenols on meat quality, xanthan gum (XG), a natural anionic polysaccharide, was employed to prevent the undesirable interaction between myofibrillar protein (MP) and gallic acid (GA, 150 μmol/g) and ameliorate the gel and emulsification characteristics of MP. XG dose-dependently alleviated the structural damage of MP caused by GA and reduced protein aggregation, manifested as the decrease in surface hydrophobicity, turbidity and aggregate size (p < 0.05) and increase in α-helix content and intrinsic fluorescence.

BackgroundThe viscosity of (BAF) influences the hemodynamics during testing of medical devices and implants in cardiovascular systems mimicking physiologic flow conditions. BAF, typically composed of water, glycerin, and Xanthan gum, is used to simulate blood's non-Newtonian shear-thinning behavior. Additionally, BAF may include microsphere particles for flow visualization in Laser Doppler Velocimetry (LDV) experiments, though their impact on viscosity remained an under-investigated area.
