When 18-year old Javier Larragoiti was told his father had been diagnosed with diabetes, the young man, who had just started studying chemical engineering at college in Mexico City, decided to dedicate his studies to finding a safe, sugar-alternative for his father.
“My dad tried to use stevia and sucralose, just hated the taste, and kept cheating on his diet,” Larragoiti told The Guardian. Stevia and sucralose are both popular sugar alternatives, and many reduced-sugar products available today contain one or the other.
With stevia and sucralose out of the picture, the young chemist needed to keep searching. He started dabbling with xylitol, a sweet-tasting alcohol found in birch wood but also in many fruits and vegetables. Xylitol is used in sugar-free products such as chewing gum and also in children’s medicine, but is toxic to dogs even in small amounts.
“It has so many good properties for human health, and the same flavor as sugar, but the problem was that producing it was so expensive,” said Larragoiti. “So I decided to start working on a cheaper process to make it accessible to everyone.”
Xylitol Made Cheaper
Corn is Mexico’s largest agricultural crop, and Javier has now patented a method of extracting xylitol from discarded corn cobs. Best of all, with 28 million metric tons of corn cobs generated every year in Mexico as waste, there’s no shortage of xylitol-generating fuel.
Simultaneously, Larragoiti hit on the idea of how to make xylitol less expensive, while inventing a way to reuse the 28 million tons of corn cobs, substantially upgrading the traditional means of disposal: burning them.
Especially in a pollution-heavy country like Mexico, reducing the amount of corn waste burned, would eliminate a portion of the carbon emissions.
His business, Xilinat, buys waste from 13 local farmers, producing 1 ton of the product each year. His invention was awarded a prestigious $310,000 Chivas Venture prize award, which will enable him to industrialize his operation and scale up production 10-fold, diverting another 10 tons of corn cob from the furnace.
