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．

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
