Abstract

Natural extract in liquid phase was adjusted to 0, 0.25, 0.5, 1, 2, and 4% concentration to check microbial changes and to measure 4, 8, $12^{\circ}C$ for refrigeration temperature. In the case of grapefruit extract, the microbial safety was maintained at all the concentrations at $4^{\circ}C$ storage, but the antimicrobial activity was maintained at $12^{\circ}C$ storage and at $8^{\circ}C$ and 21 days storage. In the case of grape seed extract, only the 4% of the culture at $8^{\circ}C$ satisfied the requirement of safety of food distribution for the last 21 days, and the safety criterion was satisfied only at 4% concentration at $12^{\circ}C$ for 18 days. Complex Scutellaria baicalensis extract showed the total number of microbial cells treated by concentration. It was confirmed that microbial flow safety was maintained at low temperature ($4^{\circ}C$). However, at $8^{\circ}C$ and $12^{\circ}C$, Exceeded the distribution limit. When polylysine was applied to brown rice cake, it showed activity in all groups except $4^{\circ}C$, but these properties were not observed at $8^{\circ}C$ and $12^{\circ}C$. At a concentration of 0.5% or more of chitosan, the growth of the microorganism is suppressed by the 21st day very stably, and a similar tendency is observed at 8 and $12^{\circ}C$, so that it may be an antimicrobial material that inhibits microorganisms. At the first day, the distribution standards for general bacterial counts were exceeded.Ethyl-pyruvate showed that microorganism safety was maintained at $4^{\circ}C$ and 1% concentration, and food safety was stable even at 2 or 4%. Glycine showed very good and stable distribution stability at $4^{\circ}C$. However, at $8^{\circ}C$ and $12^{\circ}C$, the shelf life of 14 days could not be maintained as with the addition of other antimicrobial active substances.

냉장유통을 목적으로 하는 떡류의 저장안전성을 높이기 위하여, 1차로 공정의 변화, 2차로 천연항균성 물질을 사용하여 미생물을 억제하고자 하였다. 사용한 떡류로는 녹두깨찰떡과 통팥찰떡을 사용하였고, 천연항균제로서는 자몽종자추출물, 포도씨추출물, 복합황금추출물, polylysine, chitosan, ethylpyrubate 및 glycine을 사용하였다. 액상의 천연추출물은 0, 0.25, 0.5, 1, 2, 4% 농도까지 조정하여 미생물 변화를 확인하였고 냉장온도를 위해 4, 8, $12^{\circ}C$ 측정하였다. 자몽추출물의 경우 $4^{\circ}C$ 저장에서 모든 농도에서 미생물 안전성이 충분히 유지되는 것을 확인하였으나 냉장온도 중상온에 해당하는 $8^{\circ}C$, 21일 저장에서 이미 $10^5cfu/g$를 넘어 기준에 적합하지 않은 것을 확인하였고, $12^{\circ}C$ 저장에서는 자몽추출물의 농도가 2%에서 급격히 세균수가 안정화를 이루는 것으로 보여 이 농도 또한 미생물 항균활성이 유지되는 것을 확인하였다. 포도씨추출물의 경우 $8^{\circ}C$ 배양에서 4%에서만 최종 21일 배양에서 식품유통 안전기한의 요구조건을 충족하였고, $12^{\circ}C$에서는 4% 농도에서 18일까지만 안전기준을 만족하였다. 복합황금추출물의 농도별 처리에 따른 일반 총균수를 보여주고 있는데 저온($4^{\circ}C$)에서 안정적으로 미생물의 유통안전이 유지되는 것을 확인할 수 있었으나, $8^{\circ}C$, $12^{\circ}C$에서는 다른 처리 시료와 동일하게 유통한 계치를 넘었다. Polylysine을 녹두깨 찰떡에 적용한 경우 $4^{\circ}C$에서 무첨가군을 제외한 모든 군에서 활성을 나타내는 경향을 보여주고 있으나 $8^{\circ}C$$12^{\circ}C$에서는 그러한 특성들이 보이지 않았다. Cchitosan의 농도 0.5% 이상에서는 매우 안정적으로 미생물의 생육이 억제되는 것으로 보여지고, 8, $12^{\circ}C$에서도 유사한 경향성이 보이고 있어 미생물을 억제하는 항균성 소재로서 가능성이 있을 것으로 보이나, $12^{\circ}C$에서는 모두 일반세균수에 대한 유통기준을 상회하였다. Ethyl-pyruvate는 $4^{\circ}C$, 1% 농도에서 미생물 안전이 유지되는 것을 보이고 있고 이후의 2, 4%에서도 식품으로서의 안전이 안정적으로 유지되는 것을 알 수 있다. Glycine을 0.25~4%까지 농도를 달리하여 4, 8, $12^{\circ}C$의 냉장조건에서 성장억제 현상을 관찰하였는데 저온인 $4^{\circ}C$에서는 매우 우수하게 효과적으로 유통안전성이 유지되는 것을 확인하였다. 그러나 $8^{\circ}C$, $12^{\circ}C$에서는 다른 항균활성물질의 첨가와 마찬가지로 14일의 유통기한을 유지하지 못하였다.
