| Function: |
In food industry, it is used as emulsifier, quality improver, chelating agent. It can be applied as fresh preserver, water conservation, and quality improver for quick-frozen aquatic products. Complex used with other phosphates in meat processing will get a better effect. Also it can improve the expansibility of ice cream, and the taste of flour and cake, prevent the cheese ageing. |
| Packing: |
In 25kg composite plastic woven/paper bag with PE liner. |
| Storage and transport: |
It should be stored in a dry, ventilative and clean warehouse; kept away from moisture and heat, and stored separately from poisonous Substances. Handled with care, so as to avoid damage to packing bags. |
