Effects of Water Activity and Nisin on the Growth of Listeria monocytogenes in Raw Ham
Bibliographic record
Abstract
非加熱食肉製品である生ハムにおけるL. monocytogenesの増殖に及ぼすaWおよびナイシンの影響について5試験機関で検討した結果，以下のことが明らかになった．(1）試験を実施した全機関の試験用生ハムにおいて，aw0.93 (0.930≦aW＜0.940）では，10°Cで28日間保管してもL. monocytogenes，（血清型4b，Scott A株）の増殖は認められず，国内で製造される生ハムはaw0.94未満であれば原料肉のpHや食塩，亜硝酸塩および低温保管（10°C）などの条件が相乗的に作用してL. monocytogenesの増殖は抑制される．(2）生ハムへのナイシンの添加効果は，主にL. monocytogenesの初発菌数を低減する殺菌的な作用である．(3) aw0.94 (0.940≦aW＜0.950）の生ハムでは，12.5mg/kgのナイシンを添加は損傷したL. monocytogenesの増殖に対して抑制的に作用する．

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
