초록

매실은 생과로 섭취하기 보다는 가공하여 많이 섭취하는 대표적인 과실이다. 본 연구에서는 매실의 가공식품 중 하나인 장아찌를 제조하였는데 인력에 의존하던 씨 분리 및 과육 절단 작업을 기계화를 적용하여 자동으로 작업이 가능하게 하고 그 과정에서 제조 방법의 변형이 있었다. 이렇게 제조된 매실 장아찌의 미생물 검출 및 착색료와 보존료 검출 분석을 통해 품질과 안전성을 평가하였고 관능평가를 통해 외관, 향, 맛, 식감, 기호도를 알아보았다. 그 결과, 현재 시중에 판매되고 있는 매실 장아찌와 비교하였을 때 2.7±0.1 Log CFU/g으로 일반세균에서 평균보다 다소 높은 수치가 나왔으나 그 차이가 미미하였다. 나머지 대장균, 착색료, 보존료는 모두 불검출되어 품질 및 안전성은 양호하였다. 관능평가에서는 통계적으로 큰 차이가 없었고 외관에서는 시중에 판매되고 있는 제품들 보다 좋은 평가를 받았다. 본 연구결과를 통해 매실 가공식품의 기계화를 적용할 수 있는 기반을 마련하고 주산지의 지역 경제 활성화를 촉진하고 시장 경쟁력 측면에서도 충분하다고 판단된다.

Plum is a typical fruit that is consumed processed rather than raw. In this study, we manufactured one of the processed foods, viz., plum Jangachi. In this process, the manpower-dependent seed separation and flesh cutting operations were automated by mechanizing, thereby altering the manufacturing process. Quality and Safety were assessed through microbial evaluation, analysis of color, and detection of preservatives in the plum Jangachi. Preference factors were identified through sensual evaluation. When compared with other plum Jangachi currently available in the market, our product was determined to contain 2.7±0.1 Log CFU/g total aerobic bacteria, which is slightly higher than the average of other products. This was not surprising, as the figures are due to the inherent characteristics, which were determined to be lower as compared to other commercial plum Jangachi. Other coliforms, tar dyes, and preservatives were undetected, thereby conferring satisfactory Quality and Safety. In general, there was no statistical difference in the sensual evaluation and appearance; overall, our product received better feedbacks than products on the market. Taken together, our results provide a foundation for applying the mechanization of plum-processed foods, thereby promoting the local economy in the main production area, and overall characteristics obtained are regarded sufficient in terms of market competitiveness.
