Mesh Sizes
Coarse Crystal Grades
8–20 mesh and 10–30 mesh provide larger MSG crystal sizes for formulations where a coarser particle form is required.
Medium Particle Grades
30–40 mesh and 20–60 mesh cover medium particle-size requirements for general seasoning and food-processing formulations.
Fine Particle Grades
40–80 mesh, 100 mesh and 60–120 mesh offer finer particle specifications where the formulation calls for smaller MSG particles.
Powder Grade
MSG powder is available when the purchasing specification calls for a powder-form ingredient rather than crystalline material.
Mesh Specification by Order
Specify the required mesh grade, order quantity and destination when requesting a quotation. The selected mesh grade will be confirmed against the purchase specification before order placement.
Quality Control
Assay & Physicochemical Testing
Each batch is tested for assay, pH, specific rotation, moisture, chloride and sulfate to verify the required physicochemical characteristics.
Heavy Metal Testing
Testing covers arsenic, lead, cadmium, mercury and total heavy metals before product release.
Microbiological Testing
Mould, yeast and coliform testing is conducted to evaluate the microbiological condition of the finished product.
Appearance & Sensory Inspection
Finished MSG is checked for crystal form, color, aroma and flavor against the specified product requirements.
Regulatory & Export Documentation
COA & Product Specification
A batch COA and product specification can be provided for quality review and shipment verification.
SDS & Product Information
SDS and product information are available for buyer-side technical review, import documentation and internal supplier approval.
Export Documents
Commercial invoice, packing list and other standard export documents are prepared according to the shipment and destination requirements.
Packaging & Shipping
25kg Bag Packaging
Supplied in 25kg bags for bulk orders. Buyers can specify the required mesh grade and bag quantity in the purchase order.
RFQ Requirements
For quotation, please provide mesh size, order quantity, destination port and packaging requirements.
Shipment Arrangement
Loading, palletization and shipping schedules are confirmed according to the order quantity, destination and agreed delivery terms.
