This anonymous Tuen Mun appraisal began with cordyceps stored in a metal box inside a refrigerator. The mixed arrangement included intact bodies, breaks and fragments; several specimens remained dry without obvious fuzzy growth, while some darkening required interpretation. Refrigeration neither proved good preservation nor caused automatic rejection. Seal history, condensation, odour, anatomy, foreign matter and batch consistency were checked before origin or grade was discussed.
The cold box was warmed while still sealed
Opening a cold container in humid air can deposit condensation on the specimens within minutes. The metal box was therefore photographed in place, then allowed to approach room temperature without breaking its seal. Only afterward were the lid, liner and inner surfaces checked for water marks, rust, musty smell and loose debris.
This step preserved evidence and reduced a new moisture event during appraisal. Refrigeration can be helpful only when cordyceps is already dry and isolated from refrigerator odours. A frequently opened or poorly sealed tin may cycle between cold damp air and warmer household humidity.
Unsorted contents were divided into honest groups
Intact bodies, clean breaks, loose stromata, body fragments, soil and suspect matter were arranged separately. Net readings excluded the tin and liner. Count per dry-weight unit was calculated only for the relevant whole group, so fragments could not make a batch appear larger or better selected.
Slight overall darkening could reflect age and storage, but local black spread, damp softness, webbing or powder would indicate a different condition concern. Chemical, rancid or mouldy odour was recorded before prolonged airing. No brushing, sun exposure or washing was used to make the lot look cleaner.
A claimed region still required traceable evidence
The physical review looked for natural body rings, eight leg pairs, the central four pairs, a coherent head-to-stroma junction and pale tissue at existing breaks. Artificial grooves, repeated shapes, inserted sticks, glue and wire were adverse. These checks addressed authenticity, not a precise district.
A stated Nagqu origin needed labels, supplier records or other custody evidence that matched the contents. Colour and short stromata may be compatible with that trade description, yet they overlap other authentic origins. The report therefore separated species confidence, origin confidence and present condition.
Kam Hoi Shing could describe which proportion was intact, broken, uncertain or foreign and whether the dry storage evidence remained acceptable. The Tuen Mun location had no effect on grade. Natural cordyceps does not acquire clinical proof from a gift history, and refrigeration does not guarantee future market demand. The transferable lesson is simple: warm a sealed cold package before opening, then appraise what is actually present.
