Quince seed mucilage-based scaffold as a smart biological substrate to mimic mechanobiological behavior of skin and promote fibroblasts proliferation and h-ASCs differentiation into keratinocytes.
In this study to overcome these problems, a novel QSM-based hybrid scaffold modified by PCL/PEG copolymer was designed and characterized. The properties of this scaffold (PCL/QSM/PEG) were also compared with four scaffolds of PCL/PEG, PCL/Chitosan/PEG, chitosan, and QSM, to assess the role of QSM and the combined effect of polymers in improving the function of skin tissue-engineered scaffolds. It was found, the physicochemical properties play a crucial role in regulating cell behaviors so that, PCL/QSM/PEG as a smart/stimuli-responsive bio-matrix promotes not only human-adipose stem cells (h-ASCs) adhesion but also support...

Fabrication of β-carotene loaded glucuronoxylan-based nanostructures through electrohydrodynamic processing.
Abstract Various concentrations of β-carotene (2.5-20% w/w dry mucilage weight) were loaded within Cydonia oblonga mucilage (COM) which further processed through electrohydrodynamic processing (EHP) to attain BC-Loaded nanostructures of high thermochemical stability. The BC loaded COM systems were characterized in terms of droplet size, rheological properties, surface tension, and electrical conductivity and their subsequent impacts on the morphology and physicochemical attributes of the produced nanostructures were studied. Increasing the β-carotene content, increased the viscosity and droplet size of c...

The Fatty Acid Composition and Quality of Oils From Post-Industrial Waste of Quince Chaenomeles japonica.
Abstract In the food industry, quince seeds are discarded as waste in the production process. Their use therefore creates added value and opens up the possibility of using no-waste processing technologies. Three types of waste were investigated; after juicing, after the manufacture of the puree, and syrup. The results showed that yield of quince seeds (Chaenomeles japonica (Thunb.) from waste left after different production methods varies from 29.8 to 38.3%. The cold pressed oil yield ranges from 4.9 ± 0.03 to 7.1 ± 0.06%. The oil yield obtained by Soxhlet extraction varies from 14.6 ± 0.64 to 17.3 ± 0...

Effect of drying pretreatment methods on structure and properties of pectins extracted from Chinese quince fruit.
Abstract Pectin was extracted from the sun-dried, lyophilized, and subcritical dimethyl ether (DME) dewatered fruits as well as fresh fruits, giving rise to fractions SP, LP, DP, and FP, respectively. The structure and properties of the pectin samples were investigated. Among all the pectin samples, LP had the highest yield (10.49%), the highest molar mass (Mw 65,120 g/mol), and the highest water holding capacity, and was the most thermally stable. In addition, LP exhibited the highest DPPH scavenging activity and reducing power. DP had the highest degree of esterification (72.95%), the lowest molar mass...

Optimization of whey protein isolate-quince seed mucilage complex coacervation.
In this study, the complex coacervation of whey protein isolate (WPI) and quince seed mucilage (QSM) was studied as a function of pH (7.0-2.0), biopolymers concentration (0.05, 0.1 and 0.5%) and WPI:QSM ratio (10:90 to 90:10), according to protolytic titration, electrical conductivity (EC) and turbidity analyses. The solution containing 0.5% biopolymers with WPI:QSM ratio of 70:30 resulted in maximum complex coacervation at the pHopt 4.0. With increasing WPI:QSM ratio, the peaks of pH-turbidity curves shifted to higher pH values, and with increasing biopolymers concentration, the optimum WPI:QSM ratio and pH shifted to hig...
