This study examined the effects of food additives on gram-negative bacteria. The food additives used included synthetic antioxidants (butylated hydroxyanisole, BHA, and butylated hydroxytoluene, BHT), a curing agent and lactic acid with or without a cell-free supernatant (CFS) containing antimicrobial compounds of Lactobacillus sakei D-1001. The gram-negative bacteria were selected from dry-fermented sausages and cultured with different food additives for 18 h in nutrient broth, and then another 24 h with or without CFS adjusted (at pH 6.0) to inactivate lactic acid or not adjusted (at pH 4.0). BHA (0.1%) resulted in total viable cell inhibition following 18 h culture. A reduction in cell growth was observed in culture broths with 0.1% lactic acid and... |

Fermented sausages were produced using bacterial starter culture and 3 types of mould starter cultures,and investigated their properties. Mould starter cultures were sprayed to surface of sausages at 3 days,and the surfaces were changed to white colour afterwards and another moulds, such as blue or black one,were not observed. Common bacterial and lactic acid bacterial counts were range of 6.6 x 10⁸cfu/g~2.0 x 10⁹cfu/g,and Coliform group,Staphylococcus aureus and Salmonella were not detected in the products at 35 days. pH decreased rapidly at 7 days and pH of products became to 4.6~4.7. Water contents were 30.0~31.6%,and water activity was 0.80~0.81. Nitrite ion concentration at starting time was 147.7ppm,but became to 9.8~13.2ppm in the products. There... |
