Effect of glycerol and sorbitol concentrations on mechanical
In this research, the effect of concentration (10, 20, 30, 40 and 50% starch basis) and type of plasticizer (glycerol and sorbitol) on water solubility (WS), total color difference (ΔE), mechanical properties and water vapor permeability (WVP) of films based on sweet potato starch was evaluated.
Effect of glycerol plasticizer loading on the physical
Among the plasticizing agents, glycerol has been used as a plasticizer to produce starch-based films because of its compatibility with amylose 50, which stimulates better mechanical properties...
Glycerol as an efficient plasticizer to increase the DC
The degrees of crystallinity of the polymers are noticeably decreased as a result of the glycerol plasticizer, according to X-ray diffraction test. The sample inserted with 40 wt% glycerol has the maximum ionic conductivity, according to electrical impedance spectroscopy (EIS).
The effect of glycerol concentration as a plasticizer on
As glycerol concentration increases, the thickness value of edible films is increased (Junianto et al. 2012). This is because glycerol is a clear compound, easily dissolves in water, increases the viscosity of the solution and binds water. So, the higher the addition of glycerol concentration, the lower the water
The Effect of Glycerol Plasticizer Concentration on
A plasticizer is a substance with low molecular weight, that can enter the protein-polymer matrix, so it increases the flexibility and forming capability of the film. Glycerol is included as a...
- Do glycerol concentrations affect the properties of as films?
- In the current study, different concentrations of glycerol were used to investigate the effect on physical, structural, mechanical, thermal, environmental, as well as barrier properties of AS films. This study showed that the control AS films were brittle, fragile, and not peelable from the Petri dishes.
- Does glycerol affect the mechanical resistance and mucoadhesion capacity of gellan gum films?
- Plasticized gellan gum films containing 50% w/w of glycerol showed optimal mechanical resistance and mucoadhesion capacity, which were adversely affected by the inclusion of higher concentrations of glycerol.
- How much glycerol is in a film plasticizer?
- Dunnet's test showed that there is no significant difference between the control and film plasticizer with 10% glycerol, this may be because the amount of glycerol incorporated with this concentration is not sufficient to produce changes in the polymer network. 3.4. Water vapor permeability
- Does glycerol concentration affect water vapour permeability in bio-degradable food packaging?
- The cross-sectional micrographs revealed that the films containing 45% glycerol concentration had higher homogeneity than 15% and 30%. Water vapour permeability of plasticized films increased by an increase in glycerol concentrations. The findings of this research provide insights into the development of bio-degradable food packaging.
- How glycerol affect tensile strength and elongation of bioplastic?
- The microalgae were mixed with polyvinyl and maleic anhydride as compatibilizer to strengthen the bond between the microalgae and polymer. Glycerol was added as plasticizer to increase the flexibility. Observation was carried out on tensile strength and elongation of bioplastic with a variation of 15, 20, 25, and 30 wt% of glycerol content.
- Does glycerol affect elasticity?
- The OTF 0.5 samples displayed the higher tensile stress value 30.0 ± 4.7 MPa, and a reduction in the mechanical strength was observed as the concentration of glycerol was increased (Fig. 3 B). Aside from modulating the elasticity, glycerol concentration was able to influence the film’s elongation property.
