Key Findings

01Biodegradable films maintained fruit color parameters close to their initial values after 48 hours of storage.
02Biodegradable films facilitated raspberry storage for up to 96 hours under fluctuating temperatures, maintaining a CO2 concentration between 24.4–25.9 kPa.
03While initial volatile compounds differed, after 96 hours, raspberries stored under passive and active MAP showed similar aroma profiles dominated by terpenes (73% and 62%, respectively).

Application

Design takeaway

How to apply

When designing packaging for fresh produce, consider using biodegradable films and incorporating modified atmosphere packaging principles, especially for items prone to rapid spoilage or sensitive to temperature fluctuations.

Project actions

01When selecting materials for food packaging, consider their impact on shelf life and environmental footprint.
02Investigate how different atmospheric compositions within packaging can affect product quality.

Method & Evidence

AimTo investigate the impact of different packaging films and modified atmosphere conditions on the quality and volatile aroma compounds of raspberries during storage, particularly under fluctuating temperatures.

MethodExperimental research

ProcedureRaspberries (cv. Himbo Top) were packaged using biodegradable and polypropylene (PP) films under passive and active modified atmosphere packaging (MAP) conditions. The fruits were stored for 96 hours, with an initial 48 hours at 1°C followed by 48 hours at 18°C. A PP macro-perforated film served as a control. Fruit color parameters and volatile compounds were analyzed at different time points.

ContextFood packaging and preservation

Variables

IV["Type of packaging film (biodegradable, PP macro-perforated)","MAP condition (passive, active)","Storage temperature profile (1°C then 18°C)"]

DV["Fruit color parameters (e.g., L value)","Concentration of volatile compounds (e.g., terpenes)","Overall fruit quality (implied by shelf life and aroma profile)"]

CV["Raspberry cultivar (cv. Himbo Top)","Initial fruit quality","Duration of storage (96 h total)"]

Strengths & Limitations

Strengths

+Investigated both packaging material and atmospheric conditions.
+Included a realistic temperature fluctuation scenario.

Limitations

The cost and scalability of implementing active MAP systems might be a practical limitation for widespread adoption.

Reliability & validity

The study's validity is supported by the controlled experimental design and quantitative analysis of quality parameters. Reliability would depend on the consistency of the fruit used and the precision of the analytical methods employed.

Think critically

To what extent can the findings on raspberry preservation be extrapolated to other delicate fruits, and what modifications to MAP and film composition might be necessary?

Design Principles

"Sustainable packaging solutions should actively contribute to product preservation and waste reduction."

This research highlights a practical strategy for reducing food waste and improving the economic viability of perishable produce. By understanding how packaging interacts with storage conditions, designers can develop more effective solutions for extending the freshness and appeal of fruits, leading to reduced spoilage and greater consumer satisfaction.

What This Means for Your Design

Using special biodegradable wraps and a controlled air environment can keep raspberries fresh for longer, even if the temperature changes.

How to use in your project

1.This study provides evidence for the effectiveness of MAP and biodegradable materials in preserving perishable goods, which can inform the selection of materials and packaging strategies in a design project.
