Dye-Binding Milk Protein Analyzer

染料结合乳蛋白分析仪

For farm and small dairy labs, dye binding offers an affordable route to milk protein at intake. The sample is mixed with amido black or orange G, separated by filter or centrifuge, and the unbound dye read at 550–620 nm. Results take 2–5 min with CV ≤ 1 percent; calibrate against your Kjeldahl or Dumas reference.
