Tuning the Mechanical Properties of Tapioca Starch by Plasticizers
Tuning the Mechanical Properties of Tapioca Starch by Plasticizers, Inorganic Fillers and Agrowaste-Based Fillers Figure 1 Tensile strength at break for tapioca starch modified with plasticizers (glycerol, citric acid, sorbitol), inorganic fillers (halloysite, kaolin), and/or agrowaste-based fillers (wood flour, rice bran).
Tuning the Mechanical Properties of Tapioca Starch by Plasticizers
Mechanical properties of tapioca starch-based films were tuned by different additives and additive combinations. The additives included plasticizers (glycerol, sorbitol, and citric acid), inorganic fillers (halloysite and kaolin), and agrowaste-based fillers (milled wood flour and rice bran).

- What are the mechanical properties of tapioca starch-plasticized films?
- 2.3.1 Mechanical properties Mechanical properties of tapioca starch-plasticized films which include tensile strength (TS), Young modulus (YM), and elongation at break (EAB) were determined using TA XT Plus Texture Analyzer (Texture Technologies, UK).
- Can tapioca starch film be made without plasticizer?
- Films made from polysaccharides mainly starches are able to form a continuous polymer matrix even without the addition of plasticizer (Cerqueira et al., 2011). However, tapioca starch films produced without plasticizer are usually brittle and exhibit poor mechanical strength as well as thermal stability.
- How to overcome brittleness of tapioca starch film?
- In order to overcome the film brittleness, plasticizer can be introduced as an additive in the tapioca starch film. The incorporation of plasticizer into the starch film is to enhance the flexibility of starch by reducing the intermolecular forces within polymer matrix as a result of increasing the mobility of polymer chains (Sanyang et al., 2016).
- Why is tapioca starch brittle?
- However, tapioca starch films produced without plasticizer are usually brittle and exhibit poor mechanical strength as well as thermal stability. This is due to the strong hydrophilic behavior of starch makes this material sensitive when coming into contact with water resulting in low flexibility and yield a brittle film (Avella et al.,
- What are the different types of tapioca starch films?
- Thermo-gravimetric curves for different types of tapioca starch films including i) control film; ii) glycerol-plasticized film; iii) sorbitol-plasticized film; and iv) glycerol-sorbitol-plasticized film.
- Where did tapioca starch come from?
- 2.1 Materials Tapioca starch was purchased from LGC Scientific Sdn. Bhd. Selangor, Malaysia. Food grade glycerol and sorbitol were used as film plasticizers and were supplied from R&M Chemicals, United Kingdom with a molecular weight of 92.10 g/mol and 182.17 g/mol respectively. Distilled water served as the solvent for preparing film solutions.
