22 Apr 2020 --- Start-up Savanna Ingredients is producing allulose – “real sugar without calories” – using power from the sun. The Germany-based company has installed solar panels on the roofs of all production and warehouse facilities on the Savanna site in Elsdorf in a project it calls Savanna Solar One. The move comes less than a month after the start-up received self-affirmed Generally Recognized As Safe (GRAS) status for allulose in the US for its allulose ingredient.
