Application

Design takeaway

Prioritize the use of renewable and biodegradable materials in packaging design, particularly exploring plant-based polysaccharides for food preservation applications.

How to apply

Investigate the potential of local, abundant plant materials for extracting polysaccharides to create biodegradable packaging for various food products.

Project actions

01Consider using natural materials that are readily available in your local environment for your design project.
02Think about how the material's properties can actively benefit the product it's protecting, not just act as a barrier.

Method & Evidence

AimTo develop and characterize edible coatings for cheese preservation using galactomannans extracted from non-traditional plant sources and assess their impact on cheese quality.

MethodExperimental research and material characterization

ProcedureGalactomannans were extracted from Gleditsia triacanthos, Caesalpinia pulcherrima, and Adenanthera pavonina seeds. Physicochemical properties of the extracted galactomannans and recovered phenolic compounds were determined. Edible coatings were formulated using these galactomannans, chitosan, a plasticizer, and corn oil. The wettability and physical properties of the coatings were assessed. Finally, coated cheese samples were stored at different temperatures, and their gas transfer rates, chemical, and microbiological properties were evaluated.

ContextFood packaging, dairy industry, biomaterials development

Variables

IV["Type of galactomannan source","Coating formulation (polysaccharide, plasticizer, corn oil ratios)","Storage temperature"]

DV["Gas transfer rates (e.g., O2, CO2, H2O vapor)","Chemical properties of cheese (e.g., pH, moisture content, lipid oxidation)","Microbiological properties of cheese (e.g., microbial counts)"]

CV["Type of cheese","Initial quality of cheese","Coating application method","Duration of storage"]

Strengths & Limitations

Strengths

+Utilized novel, non-traditional sources for biomaterial extraction.
+Investigated multiple aspects of coating performance and impact on food quality.

Limitations

The cost-effectiveness and scalability of extracting these specific galactomannans for widespread commercial use might be a challenge.

Reliability & validity

The study's reliability would be enhanced by repeating extractions and coating formulations multiple times. Validity is supported by assessing multiple quality parameters of the cheese.

Think critically

Beyond biodegradability, what other environmental benefits or drawbacks might arise from using plant-derived edible coatings in large-scale food production?

Design Principles

"Embrace biomimicry and circular economy principles by utilizing natural, biodegradable materials for product packaging."

This research highlights the potential of utilizing underutilized plant sources for novel biomaterials. Developing biodegradable packaging solutions is crucial for reducing environmental pollution and moving towards a circular economy in the food industry.

What This Means for Your Design

Researchers found that they could make a special coating for cheese from parts of plants, which is better for the environment than regular plastic wrap and helps keep the cheese fresh.
