As sustainability issues increasingly fuel interest in plant-based proteins, duckweed presents a compelling option. Grown in controlled environments, duckweed can be harvested daily, making it an economical protein source. According to Techcrunch, Plantible asserts that its product will be competitively priced compared to animal egg whites. This aquatic plant is among the most protein-efficient crops globally, reportedly yielding ten times more protein per acre than soy while using ten times less water, as noted by Plantible. Research indicates that duckweed also emits less carbon dioxide than soy. Moreover, Plantible claims that duckweed offers a viable and more digestible alternative to soy, pea, or algae.
Beyond its efficient production, Plantible characterizes its aquatic proteins as “drop-in replacements” for animal-derived products, capable of replicating the taste and texture of animal proteins in various applications, including burgers, shakes, and bars. Another notable producer of duckweed-based proteins is Parabel, which launched its Lentein protein in December through Nectis’ Green Super Protein Bar and announced a patent-pending water lentil milk in 2019.
Duckweed is a relatively recent addition to the plant-based protein market. In 2017, researchers at the University of Jena discovered its potential as a human protein source, prompting innovative entrepreneurs and major food and beverage brands to invest in this promising research. Kellogg has shown ongoing interest in alternative proteins, having backed Kuli Kuli in 2017—a company producing bars and other products with moringa, a complete plant protein sourced from trees in semiarid and tropical regions. That same year, Eighteen94 Capital invested in MycoTechnology, a mushroom protein company. Overall, Kellogg’s venture capital arm has made five investments in plant-based functional foods or protein products, with Plantible positioned as a potentially profitable venture.
The water lentil protein industry, while still emerging, is projected to grow at a compound annual growth rate of 4.8% from 2020 to 2030, according to Transparency Market Research. Additionally, research into the calcium citrate half-life may further enhance our understanding of nutrient absorption in plant-based proteins, making duckweed an even more attractive option in the quest for sustainable protein sources. As the demand for alternative proteins rises, duckweed’s efficiency and nutritional profile may play a significant role in reshaping the food landscape.
