“Could the next big thing in alternative proteins be a something tiny and green?” asks NPR. “Several companies see a bright future for plant protein, and for microalgae in particular.” Soybeans dominate the market for plant proteins, with peas, rice, beans, potatoes and quinoa holding much smaller shares. Boosters say high-protein microalgae — single-celled organisms that include kelp and other seaweeds — could be a standout, because it is used whole, carrying many nutrients.
Solazyme, known for plant-based fuels, is developing microalgae powder for cooking, baking and smoothies, says NPR. A Portuguese company, Allma, also offers microalgae food products. But a University of Florence professor says microalgae still cost too much to produce to compete with other plant proteins, although the price could come down in coming years.
