적용 범위

This standard applies to the production, management, and trade of Lentinula edodes (Shiitake) spawn. It covers various types of spawn including mother spawn, stock spawn, cultivation spawn, and newly added liquid spawn. It is mandatory for all manufacturers and traders operating within the Chinese agricultural sector.

기술 요구 사항

The standard specifies comprehensive container requirements, dictating the type, appearance, and sealing methods for different spawn forms, such as test tubes for mother spawn and stainless steel fermentation tanks for liquid spawn. For biological requirements, the spawn must exhibit healthy mycelium growth with clamp connections, and must be completely free from microbial contaminants and pests. The standard also defines strict sensory requirements for each spawn category, detailing mycelium density, colony characteristics, and permissible odors. A major addition in this revision is the inclusion of liquid spawn specifications, which introduces specific physicochemical parameters including pH levels, mycelium wet weight, and mycelium volume ratio. Manufacturers must ensure these physicochemical thresholds are strictly met to pass conformity assessments.

시험 방법

The standard outlines various evaluation procedures, including microscopic examination for mycelium status and clamp connections, and specific culturing methods to detect bacterial, mold, and yeast contamination. It also details sensory evaluations via visual and olfactory checks, growth speed measurements on specific media like PDA, and centrifugation techniques to determine the mycelium wet weight and volume ratio for liquid spawn. Strict adherence to these testing protocols is required for batch release.
