ZeaKal Technology Advances Toward the Perfect Soybean First to Increase Oil and Protein Without Yield Penalty Through Higher Carbon Capture News provided by Share this article Share this article SAN DIEGO, April 21, 2021 /PRNewswire/ -- ZeaKal today announced new data further demonstrating that its PhotoSeed™ technology is the first to improve the oil, protein and sustainability profile of soy, delivering greater nutritional composition and profitability across the supply chain. Across multiple field sites spanning top producing soybean states, PhotoSeed increased oil composition up to 17 percent and protein up to 7 percent on a dry weight basis – with consistent yields comparable to modern cultivars. Building on data released last year, ZeaKal's 2020 trials further proved that the novel trait technology delivered better carbon capture and overall nutritional composition in a year when the industry recorded an all-time low in soy protein levels.
