Abstract: Storing ground ordinary muscle of mackerel at 0℃ with and without antiseptics, we investigated the daily changes of lipids, bacterial counts and VBN, and obtained the following results: 1) POV, COV, TBA values and conjugated diene fatty acid contents in lipids displayed similar changes in both specimens with and without antiseptlcs, and they reached maxima after 9 days in the specimen without antiseptics and 21 days in the specimen with antiseptics. 2) Phosphorus contents in lipid decreased similarly in both specimens with and without antiseptics for 8 days. However, some fluctuation was seen in that without antiseptics after 9 days. 3) FFA contents in lipid increased similarly in both specimens with and without antiseptics for 10 days. The rate of increase was remarkably promoted thereafter in that without antiseptics. 4) Bacterial growth shifted from the logarithmic phase to the phase of negative acceleration after 10 days in the specimen without antiseptics, and to the maximum stationary phase after 21 days in that with antiseptics. 5) VBN displayed rapid increase after 10 days in the specimen without antiseptics and 21 days in that with antiseptics. / 擂潰サバ普通肉の防腐剤添加および無添加試料について,0℃付近の脂質の変化および細菌数などを経日的にしらべ次の結果を得た。1) POV, COV, TBA値および共役ジエン酸量は防腐剤添加および無添加試料とも,9日目まではほぼ類似の増加傾向を示したが,9日目を境として無添加試料では減少し,添加試料ではさらに増加を続け21日目を境として減少した。2) リン量は防腐剤添加および無添加試料とも8日目まではほぼ類似の減少傾向を示したが,9日目以後無添加試料では一時増加した。3) FFA量は防腐剤添加および無添加試料とも10日目まではほぼ類似の増加傾向を示したが,10日目を境として無添加試料では増加の割合が著しく大きくなった。4) 細菌数は防腐剤無添加試料では10日目付近を境として発育対数期から発育減速期に移行し,添加試料では21日目付近より安定期へ移行した。5) VBNは防腐剤無添加試料では10日目,添加試料では21日目以降急激に増加し始めた。
