Casein Supplier in Malaysia for Industrial Grades
- Also known as
- Milk Protein Casein
- Kasein
Casein supplier for adhesive, paper coating, paint and cheese analogue manufacturers in Malaysia. Also traded as technical casein or milk protein casein, it is the principal phosphoprotein of milk, recovered from skimmed milk as an off-white to cream granular or fine powder.
Grades are named after the way the curd is separated. Lactic casein and acid casein are precipitated with acid and stay practically insoluble until alkali is added, while rennet casein is coagulated enzymatically and keeps its calcium phosphate. Mesh cut, protein content on a dry basis, moisture, ash and free acidity are the parameters buyers specify.
Industrial demand sits in labelling and carton adhesives, plywood glue lines, paper and board coating binders, casein paints, and leather or textile finishing. Rennet grades go into cheese analogue and processed-cheese work where an edible grade applies. The sodium, calcium, potassium and ammonium caseinate salts are related soluble products, ordered by cation rather than treated as substitutes.
Send the grade, mesh, protein target, application, quantity and delivery point with your enquiry. Pack format, documentation, availability and timing follow with the quotation. Supply is subject to applicable requirements.

Casein grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Lactic casein | granular or fine powder | — | Paper and board coating binders, casein adhesives and technical protein duties where a lactic-acid-precipitated curd is the specified input. State the mesh cut the plant currently mixes. | Pack format is confirmed with the quotation. |
| Acid casein | granular or fine powder | — | Conversion into caseinate on site by dissolving the curd in alkali, and use in industrial adhesives and coatings where a mineral-acid-precipitated protein is the accepted input. | Pack format is confirmed with the quotation. |
| Rennet casein | granular powder | — | Cheese analogue and processed-cheese manufacture, where the enzyme-coagulated curd retains its calcium phosphate and is selected for the melt and stretch behaviour an acid curd does not reproduce. | Pack format is confirmed with the quotation. |
| Technical casein | coarse granular powder | — | Bottle-label and carton adhesives, plywood glue lines, traditional casein paint and leather or textile finishing, where colour and odour limits are looser than on an edible grade. | Pack format is confirmed with the quotation. |
| Caseinate salts (sodium, calcium, potassium or ammonium) | spray-dried powder | — | Systems that need a water-soluble protein rather than an insoluble curd, such as coating slips, emulsions and dispersions. These are distinct grades derived from casein rather than substitutes for the curd, so name the cation required. | Pack format is confirmed with the quotation. |

Casein applications
Safety and handling
Keep sealed in a cool, dry, well-ventilated store away from moisture and strong odours, since the powder absorbs water and can develop odour once damp. Control dust when charging and follow the safety information issued for the quoted grade.
Common questions about casein
What is the difference between acid casein, lactic casein and rennet casein?
All three are grades of the same product and differ in how the curd is separated. Lactic casein is precipitated with lactic acid, acid casein with a mineral acid such as hydrochloric or sulphuric, and rennet casein is coagulated enzymatically so it keeps its calcium phosphate. That last difference is why rennet grades are used for cheese analogue work.
Is casein the same as sodium caseinate?
No. Sodium caseinate is a separate grade made by dissolving acid casein in alkali and drying it, which turns an insoluble curd into a water-soluble protein. If the formulation needs solubility, order the caseinate by name and state the cation, because acid casein will not dissolve in its place.
Which grade suits adhesives and paper coating?
Technical and lactic grades cover most adhesive and coating work, including bottle labelling glues, carton adhesives and paper coating binders. The choice usually turns on mesh, viscosity in the alkaline solution and how tight the colour and odour limits need to be, so describe the mixing procedure with the enquiry.
Is this page about casein protein powder for sports nutrition?
No. This page covers bulk casein for industrial and food-manufacturing buyers such as adhesive makers, paper coaters, paint formulators and cheese analogue processors. Retail protein supplements and micellar protein blends are a consumer product line and fall outside this catalogue entry.
Why is acid casein insoluble in water?
Precipitation at the isoelectric point strips the protein of the charge that keeps it dispersed, so the curd stays insoluble until alkali is added. Dissolving it in sodium hydroxide, ammonia or lime is the normal way plants prepare a working solution, and the resulting caseinate is what actually binds.
What protein content is usually quoted for casein?
Industrial casein is normally traded on a protein content stated on a dry basis, together with moisture, ash and free-acidity limits. The exact figures belong to the grade being offered, so send the specification the process currently runs to and it can be matched against what is available.
What details are needed for a casein quotation?
Send the grade, mesh or particle size, protein and moisture targets, the application, quantity and delivery point, plus whether an edible or technical grade is intended. List any specification sheet or safety data sheet your approval process needs so the quotation covers it.
