Efficient extraction of a high molecular weight ulvan
Some attempts were reported for the synthesis of ulvan-based thin films destined for smart packaging. The role of plasticizers like sorbitol or glycerol was found to improve the quality of these films based on several studied parameters like solubility, transparency, UV light barrier, and mechanical properties [ 20 ].
- Are different plasticizer concentrations of Ulvan films significantly different?
- Means with different small letters (a, b) are significantly different (p < 0.05) for the same extraction condition and plasticizer type and at different plasticizer concentrations of ulvan films.
- Is Ulvan a'smart' biofilm?
- Ulvan, extracted from Ulva spp., has also been trialled as a 'smart' biofilm for eco-friendly food packaging applications , however, further research is required to understand which factors (including concentration and plasticiser type) affect the properties of smart packaging films.
- What affects the optical and thermal properties of Ulvan films?
- However, the optical, thermal, structural and antioxidant characteristics of ulvan films were strongly affected by extraction conditions and by the variation of the type and concentration of plasticizer.
- What are the characteristics and properties of Ulvan films?
- These findings have promoted a huge interest to develop the active films produced with ulvans. Additionally, many characteristics and properties of ulvan films remain unknown when the extraction conditions, plasticizer type and concentration vary: notably, the optical, thermal, structural and antioxidant properties.
- Does Ulvan film tensile strength increase or decrease?
- It is observed that the film thickness, moisture content, transparency, water vapor permeability, water-solubility, elongation at break and UV/ visible light protection of ulvan films increased, whereas, the tensile strength of the ulvan film decreased significantly .
- What affects elasticity of Ulvan-based films extracted from Ulva lactuca?
- In ulvan-based films extracted from Ulva lactuca; the film's elasticity was reported to be influenced by extraction methods as well as concentration and type of plasticizers with the highest TS and EAB of 3.5 MPa and 40 % respectively .
