Preliminary evaluation of the properties and biodegradability
The role of glycerol and sorbitol as the plasticizer in modifying the brittle characteristic of starch film into ductile was evidenced. It was found that glycerol plasticized films showed higher WVTR compared to sorbitol plasticized film due to the difference in hydrophilicity which affected the starch intermolecular network of the films.
Comparison of sorbitol and glycerol as plasticizers for thermoplastic
This article investigates the structure and properties of thermoplastic starch/PLA blends where the TPS phase is plasticized by sorbitol, glycerol, and glycerol/sorbitol mixtures. The blends were prepared using a twin-screw extruder where starch gelatinization, water removal, and dispersion of TPS into a PLA matrix were carried out sequentially.
The Comparison Effect of Sorbitol and Glycerol as Plasticizing Agents
The glycerol-plasticized films showed higher WVTR which indicated that glycerol had more positive contribution to water affinity compared to sorbitol. Biodegradability test revealed that the weight loss of unplasticized PVOH/RWF films was lower than glycerol- and sorbitol-plasticized PVOH/RWF films. Keywords: Glycerol Plasticizing agent
Effect of glycerol plasticizer loading on the physical, mechanical
This research was set out to explore the development of arrowroot starch (AS) films using glycerol (G) as plasticizer at the ratio of 15, 30, and 45% (w/w, starch basis) using solution casting
EFFECT OF SORBITOL AND GLYCEROL PLASTICIZER AND
In this study, corn starch (CS) films were developed using glycerol (G), sorbitol (S) and their combination (SG) as plasticizers at the ratio of 30, 45 and 60 (wt)% using conventional solution
- Are glycerol and sorbitol good plasticizers?
- This study aimed to compare the effectiveness of glycerol and sorbitol as plasticizers. Glycerol is considered cost-effective, renewable, biodegradable, and environmentally friendly, while sorbitol, which is also non-toxic and naturally abundant, can enhance product durability by inhibiting water evaporation.
- What is the difference between sorbitol and glycerol?
- Glycerol is considered cost-effective, renewable, biodegradable, and environmentally friendly, while sorbitol, which is also non-toxic and naturally abundant, can enhance product durability by inhibiting water evaporation. Both materials exhibit good potential as plasticizers; therefore, their comparison is necessary.
- Can glycerol and sorbitol be used as plasticizers with oxidized starch potato?
- 1. Introduction 2. Materials and Methods 3. Results and Discussion 4. Conclusions 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 ...
- Are sorbitol-plasticized Thermoplastic starch-poly (lactic acid) blends better than glycerol?
- Compared to glycerol-plasticized thermoplastic starch-poly (lactic acid) blends, sorbitol-plasticized thermoplastic starch-poly (lactic acid) blends exhibit relatively finer dispersion of the thermoplastic starch phase, resulting in much higher tensile strength and modulus than the blends plasticized with glycerol. ... ...
- Does glycerol/sorbitol ratio affect blend properties?
- It was found that the glycerol/sorbitol ratio has an important effect on the blend properties. Finer blend morphologies, higher tensile strength and modulus but lower crystallization rate were found for the sorbitol plasticized blends. (C) 2010 Wiley Periodicals, Inc.

- How can biomaterials be improved from natural biopolymers based on glycerol & sorbitol?
- The search to improve the characteristics of biomaterials obtained from natural biopolymers such as starch has led to the use of mixtures of various polymers with plasticizing agents such as glycerol and sorbitol.
