Method & Evidence

AimTo investigate the potential of polybutylene succinate (PBS) bioplastics, modified with varying percentages of extra virgin olive oil (EVO) and coconut oil (CO), for use in food packaging, focusing on their impact on food preservation and material properties.
MethodExperimental research involving material preparation, characterization, and food-contact testing.
ProcedureThin films of polybutylene succinate (PBS) were prepared with 1%, 2%, and 3% by weight of extra virgin olive oil (EVO) and coconut oil (CO). The films were characterized using ATR/FTIR spectroscopy for chemical interactions, mechanical and thermal analysis for property evaluation, and SEM for surface morphology. Finally, sliced apples and kiwis were wrapped in the films and observed for 12 days to assess oxidation and microbial contamination.

Strengths & Limitations

Strengths

  • +Investigated a novel combination of materials for bioplastic development.
  • +Included a practical food-contact test to evaluate real-world performance.

Limitations

The study used specific fruits; results might vary with different food types. The long-term effects of the oils on the bioplastic and food were not fully investigated.

Reliability & validity

The use of multiple characterization techniques (ATR/FTIR, mechanical, thermal, SEM) and a direct food-contact test enhances the validity of the findings. Reliability would be strengthened by repeating tests and using larger sample sizes for each condition.

Think critically

How might the cost-effectiveness of incorporating natural oils into bioplastics compare to traditional food preservation methods?
