Researchers in Brazil and Germany have developed a new plant-based meat substitute using sunflower flour, one of the world’s most common oil crops. Unlike other popular plant-based proteins derived from soy or pea, this offers a new direction for vegan meat alternatives that are mild-flavored and rich in minerals.
The development was published in a study in Food Research International and demonstrates that sunflower protein can provide both a firm texture and high nutritional value. This makes it a sustainable, non-GMO option for plant-based foods.
A New Use for a Familiar Crop
Sunflower oil is one of the most popular cooking oils in the world, with its production generating substantial amounts of seed meal each year. This by-product is most often used as animal feed or simply discarded. In response, researchers at Brazil’s Institute of Food Technology and the University of Campinas, together with Germany’s Fraunhofer IVV Institute, set out to explore more sustainable uses for this material.
The study received support from the São Paulo Research Foundation as part of ongoing efforts to identify plant proteins that are both environmentally sustainable and nutritionally complete. These efforts hope to eliminate the need for genetic modification and extensive processing in plant-based foods, as well as the risks associated with them.
From Seeds to Substance
Transforming sunflower seeds into a meat-like product still requires several processing steps. After oil is extracted from the seeds, the husks and phenolic compounds are removed to improve flavor and digestibility.
Lead researcher Maria Teresa Bertoldo Pacheco of ITAL’s Center for Food Science and Quality claims this step is key to achieving a clean flavor. ”After removing the husks and phenolic compounds, the flour has a very neutral taste and aroma, especially compared to the various vegetable proteins on the market,” she said.
The team developed two initial burger recipes to test using the sunflower protein. The first was made with standard roasted sunflower flour, while the other included textured sunflower protein to mimic the texture of real meat. Both recipes resulted in a pale, fine flour with little aroma but high protein and mineral content. To enhance the taste, the researchers added tomato powder, spices, and a blend of oils, including sunflower, olive, and linseed.
From there, the team shaped the mixtures into small burger patties, baked them, and ran a series of sensory and lab tests. The textured protein version came out on top. It delivered a firmer bite and a cleaner taste, along with impressive nutritional stats: roughly 49 percent of daily iron needs, 68 percent of zinc, 95 percent of magnesium, and 89 percent of manganese per serving.
A More Sustainable Alternative
Plant-based meat alternatives have grown rapidly in recent years, with most products being made from soy or pea protein. Those ingredients often come with supply-chain concerns, allergen risks, or flavors that need heavy masking. Sunflower protein provides a non-GMO, widely available, and underutilized option for plant-based meat alternatives.
Repurposing a by-product from sunflower oil production also reduces agricultural waste. The researchers note that this process could be incorporated into current food manufacturing systems, particularly as sunflower cultivation continues to increase.
A Bright Future for Plant Protein
According to Pacheco, processing methods can be adjusted to produce a range of textures, resulting in products that resemble anything from ground beef to chicken fillets. The neutral base flavor of sunflower protein also enables manufacturers to season products to suit regional preferences, without the need to mask bitterness or other flavors found in other popular plant proteins.
Soy may have paved the way for the plant-based protein market, but sunflower protein is shaping up to be a strong contender for the next wave. Its mild taste, impressive nutrition profile, and low environmental footprint make it a smart choice for new vegan meat options.
