Key Findings

  • 01BSG enrichment significantly increased protein, dietary fiber, lipid, and ash content in bakery products.
  • 02Incorporating BSG altered dough rheological properties, including increased water absorption and reduced development time.
  • 03Product color was affected by BSG enrichment.
  • 04Bakery products with 5% BSG enrichment demonstrated the highest overall consumer acceptability.

Application

Design takeaway

Consider incorporating up to 5% brewers' spent grains into bakery product formulations to improve nutritional value and maintain high consumer appeal, while being mindful of potential adjustments needed for dough processing.

How to apply

When developing new bakery products or reformulating existing ones, explore the use of brewers' spent grains as a functional ingredient, starting with a 5% inclusion rate and monitoring consumer feedback and processing characteristics.

Project actions

  • 01Investigate local sources of industrial byproducts that can be repurposed into new products.
  • 02Conduct sensory testing with a diverse group of potential users to gauge product acceptance.

Method & Evidence

AimTo investigate the impact of incorporating brewers' spent grains (BSG) at varying percentages (0%, 5%, 10%) on the technological properties and consumer acceptability of bakery products.
MethodExperimental research with sensory evaluation.
ProcedureBrewers' spent grains (BSG) were incorporated into wheat flour at 0%, 5%, and 10% levels to develop bread, breadsticks, and pizza. The study analyzed changes in nutritional composition, dough rheology, and product color. Consumer acceptability was assessed through sensory testing.
ContextFood product development, bakery industry, sustainable ingredient utilization.

Strengths & Limitations

Strengths

  • +Investigated multiple product types.
  • +Included both objective technological analysis and subjective consumer evaluation.

Limitations

The availability and consistency of brewers' spent grains may vary depending on the source. The specific processing methods used in the study might not be directly transferable to all manufacturing settings.

Reliability & validity

The study's reliability could be enhanced by repeating the sensory evaluations with larger, more diverse consumer panels and potentially conducting blind taste tests. Validity is supported by the objective measurements of technological properties alongside consumer feedback.

Think critically

Beyond nutritional and sensory benefits, what are the potential challenges and economic considerations in scaling up the use of brewers' spent grains in commercial bakery production?

Design Principles

"Valorize industrial byproducts to create sustainable and nutritionally enhanced consumer products."

This research highlights a sustainable approach to utilizing a significant industrial byproduct, transforming waste into a valuable ingredient. Designers and product developers can leverage this insight to create healthier, more environmentally friendly food products that meet consumer demand for both nutrition and taste.

06

What This Means for Your Design

You can make bread, breadsticks, and pizza healthier and tastier by adding a small amount (up to 5%) of a leftover ingredient from beer making called brewers' spent grains. People liked the products with 5% added grains the most.

How to use in your project

  • 1.Use this study to justify the selection of a sustainable ingredient in your design project.
  • 2.Reference the findings on consumer acceptance to support your product development choices.
