Determination of Harmful Substances

One of the main purposes of milk testing is to ensure that milk and milk products are safe for consumption. Milk and milk products are consumed by a large portion of the population and can potentially pose a health risk if they contain harmful substances. Especially in the case of infant formulae, it is even more critical to detect the presence of harmful substances. In addition, detecting harmful substances in raw milk facilitates the production management of milk products. Lifeasible helps detect harmful substances in milk and milk products to help make sure their safety.

Our Services

Determination of antibiotics

We help to determine antibiotic residues in milk and milk products. The antibiotics we test for include tetracyclines, β-lactams, macrolides, aminoglycosides, sulfonamides, trimethoprim, and nitrofurazone. We help detect antibiotic residues by multiple methods, including the tube diffusion test, the HPLC method, the LC-MS/MS method, the SFC method, and immunoassay.

Determination of organochlorine compounds

Organochlorine pesticides and polychlorinated biphenyls are organochlorine compounds that may be present in milk and milk products. They are harmful to humans in several ways and can accumulate in the human body. We help detect these two types of toxic organochlorine compounds in milk and milk products. We mainly carry out measurements using the gas-liquid chromatography (GLC) method.

Determination of melamine and cyanuric acid

Melamine is nitrogen-rich and is used illegally as a protein substitute. Cyanuric acid is a derivative of melamine. They are nephrotoxic. We help detect melamine and cyanuric acid in milk and milk products based on LC-MS.

Determination of microbial toxins

Microbial toxins and some metabolites of microbial toxins affect the safety of milk and milk products. We help detect many microbial toxins, including staphylococcal enterotoxins and mycotoxins. We also help detect derivatives of residual toxins, such as aflatoxin M₁, the metabolite of aflatoxin B₁ in the liver. We help enrich toxins or toxin metabolites based on methods such as immunoaffinity and dialysis, and then we perform the determination.

Determination of heavy metals

Heavy metal contamination is always a concern, and we help detect multiple heavy metals in milk and milk products, including calcium, mercury, lead, arsenic, and chromium. We can detect heavy metals based on a variety of methods, including ultra-violet (UV-Vis) spectrophotometry, atomic absorption spectroscopy (AAS), Atomic fluorescence spectrometry (AFS), X-ray fluorescence spectrometry (XRFS), and inductively coupled plasma-mass spectrometry (ICP-MS).

Determining whether a food additive exceeds the standard

Excessive food additives in milk and milk products can also pose a health risk, such as benzoic acid and sorbic acid. We help test the levels of many food additives in milk and milk products to help verify their safety.

Determination of nitrate and nitrite

We also offer services to help determine nitrate and nitrite, which can harm health in excess of their levels.
