Application
In food industry, it is used as food leavening agent, dough regulator, yeast food, brewing fermentation agent and buffer ing agent.It is mainly used as a fermentation agent, nourishment, and so on. it could be used as processing aid (only used as nutrient for fermentation). It also could be used as dough regulator and yeast food. In the fresh yeast production, it’s used as the nitrogen source for yeast cultivation (Dosage is not specified.). Dosage is about 10% (about 0.25% of wheat powder) for yeast nutrient in bread.
Package
9.5kg/bag.It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
