6. Usage: In food industry, it isused as leavening agent, dough regulator, buffer, modifier, solidification agent, nutritional supplement, chelating agent, e.g., leavening agent in bake and cake; assistant fermentation agent and buffer in bread and biscuit; pectincuring agent, yeast food, modifier in meat product. When applied in fermentation, it can increase the fermentation capacity. 7. Packing: In 25kg composite plastic woven/paper bag with PE liner. 8. Storage and transport: It should be stored in a dry, ventilative and clean warehouse, kept away from water and moisture during transport and stored separately from poisonous substances. Handled with care, so as to avoid damage to packing bags.
