Compliance-Überblick

Dieser Überblick ist derzeit nur auf Englisch verfügbar.

Geltungsbereich und Anwendbarkeit

This standard applies to the production, distribution, and use of pure cultures of Auricularia auricula (commonly known as wood ear mushroom). It specifically covers the three-tier spawn propagation system: stock cultures (mother spawn), pre-culture spawn (original spawn), and cultivation spawn. It is designed for agricultural enterprises and spawn manufacturers involved in the commercial mushroom industry.

Technische Anforderungen

The standard specifies comprehensive quality requirements for Auricularia auricula spawns across three distinct cultivation levels. For stock cultures, it mandates specific container specifications, sensory characteristics like mycelial appearance and pigment secretion, and strict microbiological purity to ensure the absence of contaminants. For pre-culture spawn and cultivation spawn, the standard dictates sensory requirements including mycelial growth density, allowable secretions, and the strict absence of antagonism and sector mutations. Any spawn exhibiting microbial contamination or abnormal physiological traits is deemed non-compliant. Additionally, it sets specific mycelial growth speed parameters under controlled temperature conditions and requires agronomic trait validation for stock cultures before commercial distribution. The standard also details packaging, labeling, transportation, and storage conditions to maintain viability.

Prüfverfahren

Compliance is verified through a combination of sensory inspections and microbiological examinations. Sensory tests involve visual observation of container integrity, mycelial morphology, and olfactory checks for off-odors. Microbiological tests utilize optical microscopy to examine water-mounted slides for fungal and bacterial contamination. Furthermore, mycelial growth speed is measured by recording the time required to fully colonize the substrate under specific thermal conditions. Stock cultures must also undergo rigorous agronomic trait testing to verify yield and morphological characteristics.

Häufige Fragen

What products are regulated under GB 19169-2003?

This standard regulates the pure culture of Auricularia auricula (wood ear mushroom), covering the production, distribution, and use of stock cultures, pre-culture spawn, and cultivation spawn.

Why is GB 19169-2003 important for mushroom spawn manufacturers?

It establishes mandatory quality, sensory, and microbiological requirements for the three-tier spawn propagation system. It ensures that only verified, high-quality mycelium is used for commercial cultivation.

Does GB 19169-2003 reference any international standards?

It references GB/T 191 for packaging pictograms and GB/T 4789.28 for microbiological testing, but it specifically focuses on the unique agronomic and biological traits of Auricularia auricula rather than providing a general international framework.
