Short answer

Design interventions that shift consumer perception from 'perfection' to 'edibility' and 'sustainability' when it comes to food.

Field: Sustainability
Source: Foods (2017)
Method: Mixed-methods research including consumer surveys, experimental interventions, and strategy validation.
Evidence: Strong effect

By understanding and influencing consumer perceptions of food quality, particularly regarding aesthetic imperfections and 'best-before' dates, significant reductions in food waste can be achieved. This sustainability research insight is drawn from a 2017 study published in Foods. Using Mixed-methods research including consumer surveys, experimental interventions, and strategy validation., researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design interventions that shift consumer perception from 'perfection' to 'edibility' and 'sustainability' when it comes to food.

Consumer acceptance of 'suboptimal' food can halve food waste

By understanding and influencing consumer perceptions of food quality, particularly regarding aesthetic imperfections and 'best-before' dates, significant reductions in food waste can be achieved.

Foods · 2017

Key Findings

01Consumers are willing to accept food that is suboptimal in appearance or nearing its best-before date if appropriately incentivized or educated.
02Targeted strategies, implemented before and after purchase, can effectively increase consumer acceptance of suboptimal foods.
03Increased acceptance of suboptimal food leads to improved resource efficiency in the food chain.

Application

Design takeaway

Design interventions that shift consumer perception from 'perfection' to 'edibility' and 'sustainability' when it comes to food.

How to apply

Implement clear labeling that distinguishes between 'use-by' and 'best-before' dates, and create dedicated sections in stores for visually imperfect produce with clear messaging about their quality and sustainability benefits.

Project actions

01Investigate consumer attitudes towards 'ugly' produce in your local area.
02Propose a marketing campaign or packaging redesign to promote the acceptance of imperfect food items.

Method & Evidence

AimHow can consumer acceptance of suboptimal food be increased to reduce food waste within the food supply chain?

MethodMixed-methods research including consumer surveys, experimental interventions, and strategy validation.

ProcedureThe project analyzed consumer behavior related to food waste, particularly focusing on the acceptance of food with minor deviations in sensory characteristics or approaching 'best-before' dates. It then developed and tested targeted strategies to promote the distribution and consumption of such food.

ContextFood supply chain and consumer behavior

Variables

IV["Consumer education on food waste and 'best-before' dates","Availability and pricing of suboptimal food","Marketing and labeling strategies for suboptimal food"]

DV["Consumer willingness to purchase suboptimal food","Consumer acceptance of suboptimal food","Perceived quality of suboptimal food"]

CV["Type of food product","Demographics of consumers","Retail environment"]

Strengths & Limitations

Strengths

+Addresses a significant real-world sustainability problem.
+Employs a multi-faceted approach to understand and influence consumer behavior.

Limitations

It can be challenging to accurately measure actual food waste reduction in a controlled project setting; often, self-reported data or hypothetical scenarios are used.

Reliability & validity

The study's reliability and validity would depend on the rigor of its statistical analysis of survey data and the controlled nature of its experimental interventions. Replication across different cultural contexts would enhance generalizability.

Think critically

To what extent are consumers' perceptions of 'quality' driven by marketing and societal norms rather than actual edibility and nutritional value?

Design Principles

"Embrace imperfection to drive sustainability."

This research highlights a critical leverage point for sustainability in the food sector. Designers and strategists can develop interventions that normalize the acceptance of food that is perfectly edible but visually imperfect or nearing its best-before date, thereby reducing waste at both retail and household levels.

What This Means for Your Design

Making food that looks a bit 'ugly' or is close to its 'best before' date more acceptable to shoppers can stop a lot of food from being thrown away.

Paragraph starter

Research indicates that a significant portion of food waste stems from consumer reluctance to purchase or consume food that deviates from aesthetic norms or is nearing its best-before date. Interventions aimed at increasing consumer acceptance of such 'suboptimal' food, through education and strategic marketing, have shown strong potential for reducing waste and improving resource efficiency within the food supply chain.
