“Exploring Duckweed: The Next Frontier in Plant-Based Protein Alternatives”
Duckweed, also referred to as water lentils or lemna, presents numerous benefits over other plant-based protein sources. This aquatic plant has a rapid growth rate in open hydroponic systems, doubling its biomass within 24 to 36 hours. Parabel, a company specializing in this ingredient, states that it takes only half an hour to process duckweed from farm to table. Its amino acid profile is comparable to whey and superior to that of soy. By the end of this year, Parabel plans to launch a water lentil-based protein ingredient that is non-GMO and allergen-free. This duckweed-derived protein can serve as a substitute for soy or pea protein in various plant-based products, including burgers, shakes, bars, and other foods and beverages. This may particularly attract consumers looking to avoid soy, as well as food manufacturers concerned about the availability of pea protein.
Another company, California-based Plantible Foods, is also working to increase duckweed production for protein ingredients. Co-founder Maurits van de Ven shared with Food Navigator last year that technological advancements have facilitated the production of high yields of duckweed as an agricultural product. In addition to its rapid growth and protein content exceeding 45%, duckweed offers a complete protein profile akin to that of eggs, containing all nine essential amino acids and six conditional ones. According to van de Ven, Plantible’s protein product behaves similarly to egg whites. Additionally, duckweed is rich in fiber, minerals, and vitamins A, B complex, and B12, which are not commonly found in other plants.
Recent studies indicating duckweed’s potential in managing glucose levels may lead to its incorporation into foods and beverages aimed at the increasing number of consumers with diabetes or pre-diabetes. Currently, over 7% of the U.S. population has diabetes, primarily Type 2, a rise from 4.4% in 2000, as reported by the Centers for Disease Control and Prevention.
However, one challenge that duckweed—or whatever name it ultimately adopts in the marketplace—will likely face is achieving name recognition. The term “duckweed” tends to create confusion and does little to distinguish this potential superfood from others available. Should the ingredient gain popularity, perceptions may shift, and consumers might actively seek it out as another viable plant-based protein option. With time, it could even attain superfood status, but manufacturers of duckweed protein will need to be patient as this unfolds.
In the meantime, consumers looking for nutritional supplements might also consider options like calcium citrate 950 mg available at Walgreens, which can complement their dietary needs as duckweed continues to establish itself in the market.
