본 연구는 돈육 중의 후지육을 이용하여 천연 향신료인 생강 및 인삼 분말을 첨가비율별로 처리(무처리 대조구, T1구(A-생강 분말 0.1% 첨가, B-인삼 분말 0.1% 첨가), T2구(A-생강 분말 0.2% 첨가, B-인삼 분말 0.2% 첨가), T3구(A-생강 분말 0.3% 첨가, B-인삼 분말 0.3% 첨가)하여 돈육포를 제조한 후, 저장기간에 따른 VBN, 미생물 수 및 관능평가에 미치는 영향을 조사하였다. 돈육포의 VBN 함량은 대조구와 처리구간에서는 통계적인 유의차가 나타내었고(p<0.01), 저장기간이 길어짐에 따라 VBN 함량과 총 세균수 및 대장균 수도 점차 증가하는 경향을 나타내었다. 또한 처리구에 상관없이 생강 분말 첨가군(A)이 인삼 분말 첨가군(B)군보다 유의적으로 낮게 나타났다(p<0.01). 돈육포의 관능평가의 경우, 육색과 맛은 처리구에 상관없이 저장기간이 길어짐에 따라 저장 2주째에 가장 높아 통계적인 유의차가 나타났고(p<0.05), 그 이후는 서서히 낮아졌다. 특히 육색의 경우, T1구의 A군이 다른 처리구보다 크게 높게 나타났다(p<0.05). 이상의 결과로 볼 때 돈육포 제조 시 생강분말 첨가는 미생물의 증식 억제에 다소 영향을 미치며, 육포제조 후 2주째에 가장 맛이 좋은 것으로 판단된다.
In this study, we analyzed 24 pieces (4×3×2) of pork jerky produced using raw meat and we then randomly assigned the hind leg meat to a treatment group. In addition, the effects of storage according to aerobic plate counts and sensory evaluation on pork jerky were examined. Form the results, We found that volatile basic nitrogen (VBN) content and aerobic plate counts of pork jerky gradually increased with increased storage time, ; moreover, there was a significant difference between the treatment groups and the control group (p<0.01). However, the counts did not increase as significantly in the ginseng powder group (B), as compared to the ginger powder group (A) (p<0.05). The sensory evaluation of pork jerky peaked during the second week of storage in all treatment groups, after which these characteristics gradually decreased (p<0.05). In addition, these characteristics were generally higher in the control group, compared to the treatment groups. When comparing the ginseng powder addition group (B) and ginger powder-addition group (A), only color was significantly higher in the ginger powder group. Based on this study as well as previous studies, storage of pork jerky significantly affects the sensory evaluation of raw pork. Ginger powder may have a more beneficial effect than other treatments on the sensory evaluation. Additionally, in all treatment groups, sensory characteristics were significantly higher in the ginger treated groups than in those of the ginseng-treated groups.
