BioVittoria and Guilin GFS Bio-Tech Co have doubled their monk fruit supply and significantly boosted production capacity following a multi-million-dollar investment leading to the formation of a new company - Monk Fruit Corp - boasting an estimated 70% share of the monk fruit ingredients market. Monk Fruit Corp has contracts with growers to produce " at least twice as much fruit as its nearest competitor this year", said the firm, which struck a deal with Tate & Lyle in 2010 to be its exclusive supplier of powdered monk fruit extract, a natural sweetener 150-200 times sweeter than sugar that is gaining traction as manufacturers come under increasing pressure to reduce sugar and keep labels clean.
