Active Biocomposite Packaging Extends Pork Shelf-Life by Incorporating Natural Antimicrobials

Food Science and Technology · 2021

Key Findings

01Nisin showed greater inhibition against Gram-positive bacteria, while OVEO inhibited both Gram-positive and Gram-negative bacteria.
02The biocomposite formulations significantly affected water vapor permeability (WVP) and mechanical properties (flexural strength and modulus).
03The active biocomposite demonstrated in vitro antimicrobial activity against target pathogens and showed potential for extending pork shelf-life.

Application

Design takeaway

How to apply

When designing food packaging, explore the use of natural, biodegradable materials combined with active compounds that can inhibit microbial growth.

Project actions

01Investigate the use of natural food-safe extracts (e.g., essential oils, plant extracts) as active agents in packaging.
02Explore biodegradable polymers like PLA or starch-based materials for packaging development.
03Consider how to integrate active agents into the packaging material without compromising its structural integrity.

Method & Evidence

AimTo develop and characterize an active biocomposite packaging material incorporating polylactic acid (PLA), oregano essential oil (OVEO), and nisin for enhanced antimicrobial efficacy in pork storage.

MethodExperimental Research

ProcedureA biocomposite base (BCCW) was created from cassava bran, coffee husk, and water. This was then coated with PLA mixed with nisin and varying concentrations of OVEO (8%, 10%, 12%) to form an active biocomposite (AB). The AB was characterized using FT-IR, WVP, mechanical property analysis, DSC, and SEM. In vitro tests evaluated inhibition against Listeria monocytogenes, E. coli, and Salmonella typhimurium. Finally, antimicrobial tests were conducted on pork meat stored with the most effective AB formulation over 10 days.

Strengths & Limitations

Strengths

+Utilizes natural and biodegradable components.
+Investigates multiple characterization techniques for the biocomposite.
+Evaluates antimicrobial efficacy both in vitro and in a food product context.

Limitations

The effectiveness of natural antimicrobials can vary greatly depending on the food product and storage conditions. Testing might be limited to specific bacteria or food types.

Reliability & validity

The use of multiple characterization techniques (FT-IR, WVP, DSC, SEM) and in vitro/in vivo testing enhances the validity of the findings. Reliability would depend on the reproducibility of the composite preparation and testing procedures.

Think critically

How might the cost-effectiveness and scalability of producing such active biocomposites compare to traditional packaging methods?
