摘要: The heat resistance of Salmonella typhimurium was determined in sucrose solutions with a(w) ranging from 0.98-0.83. D65.6 degrees C ranged 0.29-40.2 min (> 100-fold increase), z value 6.5-7.7 C. S. also heated four chocolate syrups purchased at retail. 1.2-3.2 while the 0.75-0.84. Listeria monocytogenes 0.98-0.90. shifted 0.36-3.8 (10-fold increase); 7.6-12.9
