PasLite Phosphatase Test – Pasteurisation proof for dairy products
The PasLite test is an internationally accepted method used by dairies and food manufacturers to verify HTST pasteurization for many types of dairy products, including fluid white milk, flavored dairy, non-flavored dairy, and solid/semi-solid dairy (like cheese and ice cream). The PasLite test verifies the completeness of milk pasteurization by detecting alkaline phosphatase, a natural enzyme in milk that is destroyed by the heat and hold time of pasteurization. The test takes 3 minutes and multiple samples can be run simultaneously.
When a dairy sample is mixed with PasLite reagents and incubated, the resulting solution emits light in an amount directly proportional to the phosphatase enzyme present. The Charm novaLUM II-X system is used to measure the light emitted and converts light readings to enzyme units. Phosphatase readings greater than 350 mU/L indicate product pasteurization issues according to US and EU pasteurization requirements. The PasLite test limit of detection for liquid dairy products is 20 milliunits per liter (mU/L) phosphatase (approximately 0.002% raw milk). This is well below the 350 mU/L level (0.1% raw milk) required by most public health agencies.

β-lactam 3-Min. Test (MRLBL3)
In just 3 minutes, the Charm MRLBL3 Beta-lactam Test can detect the presence of 13 primary beta-lactam drugs in milk at or below EU maximum residue limits. The MRLBL3 is run by farmers, truck drivers, milk receiving, and milk testing laboratories because of its ease of use. Add the milk sample to the MRLBL3 test and incubate for three minutes. Read results with the EZ system.
