Natural-based plasticizers and biopolymer films: A review
In another study, the same research group investigated the effect of sucrose and a mixture of GLY/sorbitol, besides GLY, urea and sorbitol as plasticizers on the microstructure, moisture sorption, water vapor permeability and mechanical properties of oat starch films kept at different relative humidity conditions [77]. Plasticizer type did not
Effect of glycerol and sorbitol concentrations on mechanical
For all plasticized SPS films (glycerol and sorbitol), the WS increased significantly as plasticizer concentration increases from 10 to 50% (see Fig. 2). A plasticizer can increase film solubility water by decreasing interactions between biopolymer chains in favor of plasticizer-polymer interactions.
Effects of glycerol and sorbitol on a novel biodegradable
The improvement in the concentration of sorbitol and glycerol caused a remarkable change (p < .05) in mechanical characteristics, which are studied in this research. As shown, although TS and YM saw a significant decrease (p < .05) upon the addition of sorbitol and glycerol, the EB improved by increasing the content of two plasticizers. The
EFFECT OF SORBITOL AND GLYCEROL PLASTICIZER AND
According to Figure 2b, the increase in sorbitol, glycerol, and mixture of sorbitol and glycerol plasticizer concentration in the cornstarch-based film decreased its density: sorbitol...
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...
- Do plasticizers glycerol and sorbitol affect cellulose films?
- Research has revealed that cellulose-based films possess high tensile strength but with subtle flexibility, which can be improved with plasticizers. This study aims to understand the effect of plasticizers glycerol and sorbitol on cellulose films.
- Can glycerol and sorbitol be used as plasticizers in Dioscorea hispida starch?
- The effects of glycerol, sorbitol, and sorbitol-glycerol mix as plasticizers at various concentrations (0, 30%, 45%, and 60%) dry starch based on the physical, morphological, tensile, and thermal characteristics of Dioscorea hispida starch films were studied. 2. Materials and methods 2.1. Materials
- How do glycerol and sorbitol interact in plasticizers?
- In both the plasticizers, the L* value increased up to 15% concentration but decreased at 25%. It appears that glycerol and sorbitol are uniformly distributed within the cellulose network stabilized by a series of hydrogen bonds, yielding soft and transparent films (Basiak et al., 2018, Suppakul et al., 2013).
- Can glycerol and sorbitol be used as plasticizers with oxidized starch potato?
- The aim of this work was to use glycerol (Gly) and sorbitol (Sor) as plasticizers with oxidized starch potato (OS) to produce biodegradable and environmentally friendly films, and to demonstrate the resulting physicochemical and functional viability without subtracting the organoleptic characteristics of the food.
- Why do glycerol films have less lightness than sorbitol films?
- However, the decrease in the lightness with an increment in plasticizer could be due to over-plasticization, which limits the cellulose chains' capacity to bind the plasticizer. In glycerol films, the a* values range from − 1.0 (7) to 2.3 (8) but are − 2.1 (4) to 2.4 (2) for the sorbitol films.
- Do glycerol and sorbitol affect water absorption capacity?
- The effect of glycerol and sorbitol on films (c) tensile strength and (d) percentage elongation at break. Overall, the water absorption capacity of glycerol films is higher than the sorbitol films, and the molecular differences between glycerol and sorbitol might be responsible.
