Ingredient identity
Acid casein is a milk-derived casein obtained by acid coagulation. Distinguish it from rennet casein and caseinates when preparing the ingredient specification.
B2B ingredient sourcing
Build an acid casein brief that connects ingredient identity with processing needs. Define the target format, particle size and sample trial before requesting a quotation.

Start with the right brief
Acid casein is a milk-derived casein obtained by acid coagulation. Distinguish it from rennet casein and caseinates when preparing the ingredient specification.
Describe your food formulation or protein-system development, including any hydration or neutralization step used in your own process.
Use these priorities to make sample comparisons and quotation discussions more focused.
Specify the required particle-size range and how it will be measured.
Provide pH, temperature, mixing and hydration conditions for evaluation.
List protein, moisture and ash targets alongside milk-allergen and origin-document questions.
Share the inputs that let us explore a suitable sourcing route for your project.
Describe the sample purpose and quantity, plus the COA, specification sheet, SDS, origin or allergen documents you would like reviewed for the proposed material.
Identify the destination market, intended use and packaging preferences, including any labeling or documentation questions for review.
Include your trial quantity, expected purchasing scale, evaluation schedule and requested quotation scope so the discussion starts with the same priorities.
