Research Objective

To comprehensively review the nutritional and sensorial attributes of bakery products incorporating quinoa flour, examining its impact on physicochemical properties, shelf-life, and consumer acceptance, and to inform the development of innovative and nutritious bakery products.

Methodology

This is a review article that synthesizes existing research on the use of quinoa flour in various bakery products. It analyzes nutritional content, sensory characteristics (taste, texture, aroma, appearance), physicochemical properties, and shelf-life.

Discussion

The incorporation of quinoa flour into bakery products offers significant nutritional advantages, making them suitable for health-conscious consumers and those with gluten intolerance. While quinoa flour contributes positively to texture and digestibility, challenges exist in optimizing its use to maintain desirable sensory attributes like appearance and taste, particularly in bread. The review highlights the need for careful formulation and processing to balance nutritional benefits with consumer acceptance.

Key Findings

Quinoa flour enhances the nutritional profile of bakery products by increasing protein, fiber, vitamins, and minerals. It is a complete protein source and gluten-free. Quinoa flour can positively influence texture, slow down staling in bread, and reduce rapidly digestible starch. However, high concentrations can negatively impact dough stability, loaf volume, and appearance in some products. Cakes, cookies, and flatbreads show the most acceptable results overall, while bread requires further optimization.

Conclusion

Quinoa flour is a valuable ingredient for developing healthier bakery products. Its nutritional benefits are well-established, and it can improve various aspects of baked goods. Further research and optimization are needed, especially for products like bread, to fully leverage quinoa flour's potential without compromising sensory quality.
