Can alum in sweet potato vermicelli be replaced by baking soda?

Soda powder can't replace alum. Using alum to make vermicelli is the indiscriminate use of food additives. Soda powder and alum have the opposite effect. Alum can make vermicelli dense, baking soda can make vermicelli swell, and vermicelli is full of pores without tendons. Only gluten source can replace alum to make vermicelli. The source of gluten has been examined and approved by Shandong Quality Supervision Bureau, and the General Administration of Quality Supervision, Inspection and Quarantine has issued the QS certificate of national industrial product production license, which is safe and legal, and does not exceed the standard and scope.
