Application
In food industry, it is used as rapid ferment agent, quality improver and applied as acid component of bread and cake's synthetic leavening agent.
Mixed with other phosphates can be applied to water retention of meat products, such as canned meat, cooked ham, meat can and instant noodle.
Important Notice
We normally list 2 years as the shelf life in our COA, the real shelf life is actually much longer than 2 years if it's stocked in good condition (bags are sealed enough, away from direct sun-light, moisture and other incompatible chemical materials)
