Aperçu de conformité
Cet aperçu n’est actuellement disponible qu’en anglais.
Champ d’application
This standard applies to feed additive nicotinamide obtained through chemical synthesis. It is mandatory for all manufacturers producing and supplying this specific vitamin supplement within the Chinese market. It does not apply to naturally derived or biologically fermented nicotinamide products.
Exigences techniques
The standard specifies the physical and chemical requirements for feed additive nicotinamide. Appearance requirements dictate it must be a white crystalline powder or granular powder, odorless or nearly so, with a bitter taste. Manufacturers must ensure strict compliance with the technical indicators outlined in the standard. Key parameters regulated include the minimum nicotinamide content, specific melting point range, and pH value limits for a 10% solution. Additionally, the standard sets maximum limits for loss on drying, heavy metals (calculated as Pb), total arsenic (As), and ignition residue.
Méthodes d’essai
The standard outlines specific testing methodologies to verify compliance. Identification tests include chemical reactions, ultraviolet spectrophotometry (measuring absorption at 262nm and 245nm), and infrared spectrophotometry. The nicotinamide content is determined using potentiometric titration with a perchloric acid standard solution. Other tests include melting point determination, pH measurement per GB/T 9724, loss on drying via an oven method, heavy metal analysis using a thioacetamide colorimetric method, total arsenic via a silver diethyldithiocarbamate colorimetric method (arsenic spot method), and ignition residue testing.
