적용 범위

This standard applies to the production, management, and trade of Agaricus bisporus spawn. It covers container requirements, quality specifications, inspection rules, and labeling for mother spawn, stock spawn, cultivated spawn, and liquid spawn. It is mandatory for all manufacturers and traders involved in the Agaricus bisporus spawn industry in China.

기술 요구 사항

This standard specifies the physical and biological requirements for Agaricus bisporus spawn, categorized into mother spawn, stock/cultivated spawn, and liquid spawn. It outlines specific container types, such as test tubes, glass/plastic bottles, and stainless steel fermenters, ensuring they meet strict integrity and sealing criteria. For quality control, the standard mandates that all spawn must meet varietal characteristics and biological purity, explicitly requiring the absence of foreign fungi, insects, and eggs. Sensory requirements dictate the appearance, mycelium growth status, and odor for each spawn type. A significant update in this version is the inclusion of liquid spawn requirements, introducing specific physicochemical parameters such as pH, mycelium wet weight, and mycelium volume ratio. Manufacturers must ensure these parameters are strictly met to pass compliance. The standard also details packaging and transportation protocols, requiring product certificates, usage instructions, and protective measures against shock, sunlight, and contamination during transit.

시험 방법

The standard describes various testing methods to verify compliance. Container and sensory inspections are primarily conducted visually under natural light, with microscopic observation for biological purity. Mycelium growth speed is evaluated under controlled temperatures using specified media like PDA or grain-based substrates. For liquid spawn, physicochemical properties are tested using centrifugation for mycelium wet weight and pH meters for acidity.

자주 묻는 질문

What products are regulated under GB 19171-2026?

GB 19171-2026 regulates Agaricus bisporus spawn, including mother spawn, stock spawn, cultivated spawn, and the newly added liquid spawn.

Are there any updates from the previous version of GB 19171?

Yes, compared to GB 19171-2003, this version adds quality requirements for liquid spawn, updates container and biological requirements, and modifies testing methods and labeling rules. Manufacturers must update their processes to meet these new criteria.

What are the key testing parameters for liquid spawn?

For liquid spawn, the standard specifies testing for pH, mycelium wet weight, and mycelium volume ratio, along with sensory checks for color, morphology, and odor.
