Abstract

The aim of this study was to investigate the physicochemical characteristics of native Korean Allium wakegi Araki samples, which were grown from seven local seed bulbs(Yesan, Muan, Anmyon-do, Deokjeok-do, Jeju-do, Yecheon, and China) to produce high quality native Korean Allium wakegi Araki. For the proximate composition of samples, moisture contents were in the range of 90.69~92.43%. The crude protein content of the Jeju-do sample was highest compared to the other samples. However, there were no significant differences in total sugar contents between samples. The seed bulb origin did not affect the hardness of the stem part, but was high for the leaves of the Yesan sample compared to the other samples. The results for anti-oxidative activity were as follows: Yesan(2.30 mg/mL) > China(2.51 mg/mL) > Muan (2.56 mg/mL) > Yecheon(2.74 mg/mL) > Jeju-do(2.85 mg/mL) > Anmyon-do(2.87 mg/mL) > Deokjeok-do(3.18 mg/mL). In terms of mineral and amino acid contents, the Yesan sample showed the highest levels, respectively, compared with the other samples. Food values such as contents of total phenolics and pyruvic acid were highest in the Jeju-do sample. These results show that the physicochemical characteristics of Allium wakegi Araki were significantly different according to different seed bulb origins.

한국산 쪽파의 품질 향상을 위해 7개 지역의 쪽파 종구로 재배된 쪽파에 대한 이화학적 특성 분석을 실시하였다. 일반 성분 분석 결과, 쪽파의 수분 함량은 예천 쪽파, 조단백 함량은 제주도 쪽파, 조지방 함량은 예천 쪽파의 함량이 가장 높게 나타났다. 조회분 함량은 중국 쪽파가 가장 높았고, 환원당 함량은 덕적도 쪽파의 함량이 가장 높게 나타나 유의적 차이를 나타냈는데, 총당 함량은 0.36~0.41% 수준으로 유의적 차이가 없었다. 줄기 부분에 대한 경도는 시료 간에 유의적 차이가 없었고, 잎의 경도는 예천 쪽파가 가장 높았다. 수소공여능은 예산 > 중국 > 무안 > 예천 > 제주도 > 안면도 > 덕적도의 순으로 나타났다. 무기질은 K, Ca, P, Mg, Na 등 의 순으로 함량이 감소하였고, 특히 예산 종구로 재배된 쪽파의 함량이 높은 것으로 나타났다. 쪽파의 구성 아미노산은 18종 중 17종이 분석되었으며, 이중 glutamic acid의 함량이 가장 많았다. 매운맛을 나타내는 pyruvic acid 함량은 제주도 종구 재배 쪽파가 가장 높았고, 중국산 종구 재배 쪽파가 가장 낮게 나타났다. 이와 같은 결과로 종구산지가 다른 7가지 쪽파의 이화학적 특성은 유의적 차이가 있는 것으로 확인되었으며, 국내산 쪽파 및 종구의 품질향상을 위해 종구에 따른 국내산 쪽파의 생리활성에 대해서 더 깊은 연구가 필요하다고 사료된다.
