Abstract
The effect of NaCI content levels(1.7, 2.2, 2.7 and 3.2%) on the ripening of a dry sausage was studied, when starter culture and Glucono-delta-Lacton were used. During the ripening of sausages, the physical and chemical properties and the microbial mutiplication were investigated, and also the growth of inoculated Staphylococcus aureus was detected, pH values were slowly decreased and Aw values dropped fastly during ripening period with the increase of NaCl content. In instrumental texture examination, the texture of sausage with NaCl content of 3.2% was significantly harder and more cohesive than those with lower NaCl contents. During ripening St. aureus was decreased by one tenth and not significantly different among mixtures with different NaCl contents. Depending upon reducing NaCl levels, total bacteria and Lactobacilli grew rapidly, while Enterobacteriaceae decreased slowly during ripening.
식염의 1.7%, 2.2%, 2.7% 그리고 3.2%의 첨가수준에 따라 발효소세지의 숙성 및 건조중 이화학적 변화 및 미생물의 변화를 조사하였으며 또한 Stahpylococcus aureus의 접종시험을 통해서 이들의 증식관계를 조사하였다. 소금의 첨가량이 많아짐에 따라 pH는 완만하게 떨어졌으며 모든 처리구 공히 원료혼합육 5.8 수준에서 최종제품 4.8-4.6의 pH를 나타내었다. 조직은 소금의 첨가량이 높을수록 저작성과 경도가 높게 나타났으며 낮은 식염처리구에서는(1.7%, 2.2%)제품으로서의 조직을 갖지 못했다. 소금의 첨가량이 많아짐에 따라 총 세균수와 Lactobacilli수는 낮은 수준을 보였으며 아울러 완만하게 증식하는 경향을 나타내었다. 원료혼합육 g당
