Sunflower flour for vegan meat: A plant-power breakthrough in sustainable protein

That golden field of sunflowers waving under the sun is more than just a pretty sight. It could be the source of your next burger-patty alternative. The humble sunflower seed, once stripped of its oil-rich kernel, has been transformed into a nutrient-dense flour that mimics meat’s texture and packs serious protein. Researchers collaborating across Brazil and Germany have developed this sunflower-based vegan meat alternative with promising results.

A peer-reviewed study published in Food Research International found that textured sunflower protein patties delivered around 20 percent protein, healthy monounsaturated fats, and rich mineral content including iron, zinc, magnesium, and manganese. With food systems under pressure and demand for sustainable protein rising, this sunflower-derived alternative could mark a major shift in plant-based meat products.



Why sunflower flour is emerging as a viable meat alternative
Traditional plant-based proteins often rely on soy or pea, but sunflower flour presents unique advantages. The raw material, the leftover meal after oil extraction, offers a circular economy benefit. Researchers developed two formulations: one from roasted sunflower flour and the other from textured sunflower protein. The textured version outperformed in taste tests, texture, and nutrient density.

Sensory panels found that sunflower-based patties had a texture and mouth-feel comparable to meat alternatives. Nutrition-wise, the textured sunflower protein variant offered high protein at around 20 percent, healthy fats, 49 percent of the RDA for iron, 68 percent for zinc, 95 percent for magnesium, and 89 percent for manganese.
Sunflower flour is proving its worth as a realistic meat substitute and not just a filler protein.



How the sunflower flour meat alternative was developed

The process began with oil extraction from sunflower seeds. After removing husks and phenolic compounds that can impair digestibility and darken the flour, the remaining meal was refined.
Two prototype patties were created:

• Flour-based: roasted sunflower flour enriched with tomato powder, spices, and a lipid blend including sunflower, olive, and linseed oils.
• Textured sunflower protein (MAMt): the same base but processed to mimic meat fibres using extrusion techniques.
• Both versions were baked into mini-burgers and tested for nutrition, texture, and taste. The textured version performed better in consistency and nutrient density.
• The refined flour’s neutral taste and aroma give it an advantage over many plant proteins that often carry strong vegetal flavours.

Sustainability and market potential of sunflower-based meat alternatives
Sustainability is a major factor in this innovation. Sunflowers are widely grown, oil extraction is already established, and the leftover meal is underutilised. Converting this by-product into human-edible protein creates a low-waste solution.
Sunflower cultivation is not heavily GMO-dependent in many regions, which may appeal to consumers seeking non-GMO alternatives.

The plant-based meat sector continues to grow rapidly. Introducing sunflower flour as a base ingredient broadens raw material options, diversifies supply chains, and reduces reliance on a few dominant crops. Sunflower flour patties may soon appear in pizzas, sliders, and ready meals around the world.



Nutrition, challenges, and future directions for sunflower meat alternatives

Although results are encouraging, sensory and functional properties such as taste, texture, and shelf-life must match or surpass current market leaders to gain consumer acceptance. Researchers note that more flavour optimisation is needed.
Extraction and processing affect protein yield. High fibre content in sunflower meal can reduce protein extraction and impair functionality. Optimised processing could raise protein content to around 49 percent, but equipment and process costs must be considered.

Future work will focus on improving meat-like texture, expanding flavour profiles, performing lifecycle and environmental assessments, and conducting consumer acceptance studies globally.



Sunflower flour is emerging as a serious contender for sustainable, scalable plant-based protein. Peer-reviewed research shows strong nutrition, good texture, mild flavour, and the added advantage of using a by-product. As consumers increasingly prioritise health, sustainability, and food transparency, sunflower flour-based products may move from novelty to norm. Your next burger could very well be powered by sunflowers.
