Escopo e aplicabilidade

GB 7300.207-2025 applies to feed additive nicotinamide (Vitamin B3) synthesized chemically from 3-cyanopyridine. This standard is mandatory for manufacturers producing, testing, and distributing nicotinamide products for the animal feed industry in China. It replaces the previous GB 7301-2017 and is categorized under the vitamins and provitamins section of the GB 7300 series.

Requisitos técnicos

The standard defines the chemical profile of nicotinamide, including its molecular formula (C6H6N2O) and relative molecular mass. It mandates that the product must appear as a white crystalline powder or granular powder, being odorless or nearly so. Identification protocols require chemical, ultraviolet, and infrared spectroscopy verification to ensure the sample matches standard reference spectra. For physicochemical parameters, the standard sets strict limits for nicotinamide content, melting point range, pH value, loss on drying, and ignition residue. Manufacturers must ensure their product meets these precise physicochemical thresholds to be deemed compliant. Additionally, the standard enforces critical sanitary indicators by setting maximum limits for heavy metals (as Pb) and total arsenic (as As). These limits are designed to prevent toxic contamination in the animal feed supply chain.

Métodos de ensaio

Testing procedures include potentiometric titration using a perchloric acid standard solution to determine the exact nicotamide content. Ultraviolet-Visible spectrophotometry is utilized for UV identification, while Fourier-transform infrared spectroscopy (FTIR) confirms the molecular structure. Other routine tests include vacuum drying for loss on drying, muffle furnace incineration for ignition residue, and a comparative colorimetric method (arsenic spot test) for total arsenic determination.

Perguntas frequentes

What products are regulated under GB 7300.207-2025?

This standard specifically applies to feed additive nicotinamide synthesized chemically from 3-cyanopyridine. It replaces the previous GB 7301-2017 and is part of the broader GB 7300 series for feed additives.

Are there any updates from the previous version of GB 7300.207-2025?

The 2025 version changes the scope of application, updates the testing methods for loss on drying and heavy metals (as Pb), adds precision requirements for the ignition residue test, and modifies the factory inspection items.

What are the mandatory factory inspection items for nicotinamide under this standard?

Factory inspection is mandatory for every batch, covering appearance and properties, nicotamide content, and pH value. Full type inspection covering all technical and sanitary indicators must be conducted at least every six months.
