Abstract

In this study we evaluated the antimicrobial effects of EcoCal® (calcium oxide) and GF Bactostop® (organic acids mix) in sausages during storage at 10℃. The sausages were formulated with 0.1% EcoCal® (0.1ECO), 0.1% EcoCal®+0.5% GF Bactostop® (0.1ECO+0.5GF), 0.2% EcoCal® (0.2ECO), and 0.2% EcoCal®+0.5% GF Bactostop® (0.2ECO+0.5GF). Total aerobic and lactic acid bacteria in the sausages were enumerated on tryptic soy agar and Lactobacilli MRS agar, respectively, during storage at 10℃ for 10 weeks. The 0.1ECO+0.5GF showed the most effective antimicrobial effects on the sausages, and 0.1ECO showed the second most effective antimicrobial effect. Total aerobic bacterial cell counts gradually increased in the control, 0.2ECO, and 0.2ECO+0.5GF groups, but cell growth was generally inhibited in 0.1ECO by approximately day 42 (P<0.05) and 0.1ECO+0.5GF by approximately day 49 (P<0.05). Lactic acid bacterial cell counts gradually increased in the control, 0.2ECO, and 0.2ECO+0.5GF groups, but the lactic acid bacteria growth was inhibited in 0.1ECO by approximately day 49 (P<0.05) and in 0.1ECO+0.5GF by approximately day 64. These results suggest that using 0.1% EcoCal®+0.5% GF Bactostop® in sausage formulation is useful for inhibiting lactic acid bacteria growth, thereby extending the shelf-life of the sausage product.

본 연구는 EcoCal® (산화 칼슘) 및 GF Bactostop® (유기산염 믹스)을 소시지에 사용하였을 때 항균 효과를 확인하였다. 소시지 제조 시, 대조군과 0.1% EcoCal® (0.1ECO), 0.1% EcoCal®+0.5% GF Bactostop® (0.1ECO + 0.5GF), 0.2% EcoCal® (0.2ECO) 및 0.2% EcoCal®+0.5% GF GF Bactostop® (0.2ECO+0.5GF) 등 총 5개 군을 첨가하여 소시지를 제조하였다. 제조가 완료된 소시지를 진공포장하고 10주 동안 10℃에서 저장하며 7-10일 마다 시료를 균질화 하고 tryptic soy agar 및 Lactobacilli MRS agar에 도포하여 호기성 일반세균 및 젖산균을 각각 확인하였다. 그 결과, 0.1ECO+0.5GF 첨가한 소시지가 가장 효과적인 항균 효과를 나타냈으며, 0.1ECO 첨가 소시지가 두번째로 효과적인 항균 효과를 나타냈다(P<0.05). 일반세균수는 대조군, 0.2ECO 및 0.2ECO+0.5GF 첨가 소시지에서는 저장 후 42일까지 점차 증가했지만(P<0.05), 0.1ECO 및 0.1ECO+0.5GF 첨가 소시지에서는 저장 후 49일까지 일반세균의 생장이 억제되었다(P<0.05). 젖산균 수는 대조군, 0.2ECO 및 0.2ECO+0.5GF 첨가 소시지에서 약 49일까지 증가하였으나(P<0.05), 0.1ECO 및 0.1ECO+0.5GF 첨가 소시지에서 젖산균 생장이 억제되었다. 본 결과는 소시지 제형에 0.1% EcoCal®+0.5% GF Bactostop®을 첨가하면 젖산균의 생장을 억제하여 소시지의 보존 기한을 연장시키는데 유용할 것으로 판단된다.
