Ferrous lactate detection

This standard specifies the technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, and shelf life of food additive ferrous lactate. This standard applies to trihydrate products of ferrous lactate produced by the reaction of calcium lactate, sodium lactate, or ammonium lactate with ferrous sulfate or ferrous chloride, or by the reaction of lactic acid with iron powder. The clauses in the following normative references become the clauses of this standard through the reference surface of this standard. All dated references, subsequent amendments (excluding corrected content) or revisions are not applicable to this standard. Therefore, all parties who have reached agreements based on this standard are encouraged to study whether the latest versions of these documents can be used. For undated references, the latest version applies to this standard.
