As interest grows in foods that offer both nourishment and functionality, bread has become a key target for plant-based protein enrichment. Yet adding alternative proteins typically disrupts gluten networks, leading to dense loaves, reduced volume, or changes in texture and color. These challenges often limit how much nutritional enhancement can be achieved without affecting product quality.

A recent study examined whether sacha inchi protein, known for its balanced amino acid profile and high digestibility, could enhance the nutritional value of wheat bread while maintaining the qualities people expect from a traditional loaf.

The Study

Ecuadorian researchers prepared several forms of protein extract from sacha inchi seeds and blended them into standard wheat bread dough.

They evaluated how the enriched dough behaved during mixing and heating, how the bread baked and rose, and how its texture, color, and internal structure compared to regular wheat bread. To measure nutritional improvements, they analyzed protein content, amino acid composition, in vitro digestibility, and overall protein quality.

The Results

Sacha inchi protein clearly improved the bread's nutritional value. Protein content increased by up to 26.4%, and protein quality values rose by as much as 10%, reflecting a more balanced amino acid profile and greater digestibility than traditional wheat bread.

Just as importantly, these improvements did not negatively affect bread quality. Dough behavior remained consistent with the control, showing no signs of weakening or reduced elasticity. Baking performance was preserved as well, with loaf volume, crumb texture, and color comparable to regular wheat bread. The enriched breads maintained the softness and appearance consumers expect.

What Does this Mean?

This study shows that sacha inchi protein can significantly enrich bread without compromising texture or baking performance, offering a practical approach for creating higher protein, plant forward bakery products. As interest in functional ingredients continues to grow, sacha inchi stands out for its nutritional balance, stability, and compatibility with familiar foods.

Similar results have also been observed with other nutrient dense plant ingredients such as quinoa and amaranth, which can enhance protein quality while maintaining desirable baking characteristics.
