Escopo e aplicabilidade

This standard applies to food nutritional fortification substances, specifically calcined calcium derived from oyster shells or other shells through high-temperature calcination and hydrolysis. It is mandatory for manufacturers producing calcined calcium for use in food products in China. The standard does not apply to other forms of calcium or non-calcined calcium products. It references GB/T 5009.3 and other related national standards for testing methodologies.

Requisitos técnicos

The standard outlines specific sensory requirements, mandating that the product must be a white, odorless powder. It also establishes strict physicochemical limits for the substance. Key parameters regulated include calcium content, moisture, fineness, and the maximum allowable levels of heavy metals such as arsenic, lead, and cadmium. Additionally, it sets thresholds for hydrochloric acid insoluble matter and barium content. Compliance with these physicochemical parameters is mandatory to ensure product safety and efficacy. The standard also details the requirements for packaging, labeling, transportation, and storage, specifying a minimum shelf life of 12 months under proper conditions.

Métodos de ensaio

The standard specifies various analytical methods to verify compliance. Calcium content is determined using an EDTA titration method. Moisture is tested according to GB/T 5009.3, while heavy metals like arsenic, lead, and cadmium are measured using specific national standards (GB/T 5009.76, GB/T 5009.75, and GB/T 5009.15 respectively). Fineness is evaluated through sieve analysis, and hydrochloric acid insoluble matter is quantified using a gravimetric method. Manufacturers must follow these exact testing procedures to validate product conformity.
