Determination of Inorganic Elements

The determination of inorganic elements in milk and milk products is required. Lifeasible offers a comprehensive inorganic element determination service to help determine a wide range of inorganic elements.

Determining inorganic elements can be used to assess nutrition, safety, and cheese production performance. Milk contains more than 10 inorganic elements. Most of them are present in trace amounts, but they have an important impact on human health. Milk contains various inorganic elements essential for human health, such as zinc, iron, and selenium. By determining the levels of these elements, the nutritional content of the milk can be determined and evaluated. Some inorganic elements, such as heavy metals (Fig. 1), can be toxic in high concentrations and pose a health risk. In addition, some inorganic elements affect rennet activity, such as calcium.

Our Services

We help to determine the inorganic elements in milk and milk products, referring to the methods of international standards.

Measurement contents and reference methods

Scope of application of methods

ISO 11813:2010 is applicable for milk and milk products with zinc contents between 25 mg/kg and 70 mg/kg (dry mass).

ISO 5738:2004 is applicable for kinds of milk (milk, skimmed milk, buttermilk, evaporated milk, and sweetened condensed milk), whole and skimmed milk powder, cream, butter, butterfat; cheeses, caseins, caseinates, and coprecipitates.

ISO 15151:2018 is applicable for milk, milk powder, butter, cheese, whey, whey powder, infant formula, and adult nutrition formula.

ISO 21424:2018 is applicable to determine 12 inorganic elements of infant formula and adult nutrition formula. In addition to Cr, it can determine the other 11 inorganic elements of milk, milk powder, whey powder, butter, and cheese.

ISO 8070:2007 is applicable for milk and whey, buttermilk, yogurt, cream, dried milk, butter, cheese, casein, and caseinate.

ISO 6732:2010 is applicable for milk, yogurt; evaporated milk, sweetened condensed milk, dried milk, dried whey; dried buttermilk, cream, butter; anhydrous butterfat, butteroil, butterfat, ghee, ice-cream, cheeses, caseins, caseinates and coprecipitates.

ISO 12081:2010 is applicable for milk and milk reconstituted from evaporated, condensed, or dried milk.

ISO/TS 9941:2005 is applicable for canned evaporated milk.

ISO/TS 6733:2006 is applicable for milk and milk products. It is an ISO technical specification and IDF review method rather than an international standard.
