What are Calcium Sulfate and Glucono Delta Lactone listed on House Premium Tofu labels? Are these substances used as preservatives?
They are both coagulants and are not preservatives. Since Tofu is made from soymilk, it must be coagulated by using Calcium Sulfate and Gulcono Delta Lactone. Gulcono Delta Lactone is a coagulant made from corn syrup. House Premium Tofu is pasteurized by a unique double-cool pasteurizing method and does not contain any preservatives.
