With demand for rare sugar allulose currently exceeding supply, Tate & Lyle has informed some partners that it is withholding supplies of the sweetener until further notice, FoodNavigator-USA understands. One sweeteners company, which supplies a wide variety of sweeteners used in packaged foods and beverages including top-seller allulose, told us that he had just been informed that Tate and Lyle was not supplying allulose " until further notice." Tate & Lyle - which manufactures liquid and crystalline allulose from its site in Loudon, Tennessee - told us that it would not comment on conversations with customers, although it acknowledged that " the current huge increase in demand currently exceeds supply."
