One-pot synthesis of high fructose corn syrup directly from starch with SO42./USY solid catalyst
E-mail:,
An efficient process was developed for the conversion of starch directly into high fructose corn syrup (HFCS) by using SO4 2-/USY solid catalyst in water. The SO4 2-/USY catalyst was found to act as a bifunctional catalyst with high activity for both hydrolysis of starch and isomerization of glucose, achieving a one-step preparation path of HFCS from starch. An optimal HFCS yield, containing 58.34% glucose and 27.84% fructose (mass fraction), was obtained at 150 °C for only 1 h.
