초록

창포 뿌리를 주근(main mot)과 측근(lateral root)으로 분리하여 열풍건조 분쇄, 분말화한 후 일반성분, 당 및 아미노산등 화학성분을 분석하여 식품학적 특성을 검토하였다. 주근과 측근 건조분말에는 각각 조단백질 12.76%, 9.84%와 조지방 7.43%, 3.42%로 높게 함유하고 있어 에너지공급원과 식물성 고단백질 원료로서의 우수한 영양학적 가치를 가지고 있음을 확인하였다. 유리당으로는 sucrose, stachyose, raffinose, glucose 및 fructose 등으로, 특히 sucrose가 주근과 측근에 각 10.85%와 12.27%로 높게 함유하고 있었다. 창포뿌리 주근의 건조분말은 총아미노산 함량은 426.81 mg%이었고, 특히 arginine 78.91 mg%와 glutamic acid 69.73 mg%로 높은 함량 수준을 보였다. 측근 건조분말의 총아미노산 함량은 470.13 mg%로 주근 보다 다소 높은 함량을 나타내었고, 특히l arginine이 116.91 mg%로 주근의 arginine 함량보다 매우 높은 함량 수준을 보였다. 주된 유리아미노산으로는 asparagine, arginine, glutamic acid, phenylalanine 등의 순으로 높게 함유되어 있고, 특히, 주근 건조분말에는 asparagine이 128.53mg%, 측근 건조분말에는 arginine이 86.10 mg%로 높은 함량 수준을 나타내었다. 필수아미노산 함량은 유리아미노산의 경우는 phenylalanine, threonine, valine, leucine 등이 높게 함유되어 있었으며, 특히, 주근 건조분말에는 threonine이 15.62 mg%, 측근 건조분말에는 phenylalanine 12.67 mg%로 타 필수 아미노산에 비해 매우 높은 함량 수준을 나타내었다.

This study has been carried out to investigate the food chemical composition in dried powder of main and lateral root of Acorus calamus L. Content of crude protein and crude fat in dried powder of main and lateral root were 12.76% and 9.84%, 7.43% and 3.42%, respectively. Total and reducing sugar of main and lateral root were 21.99% and 7.67%, 24.12% and 0.65%. Major free sugars of root were sucrose, stachyose, raffinose, glucose and fructose. Sucrose of main and latent not were found to be the most predominant free sugars, contained 10.85 % and 1257%. Content of total amino acid were 427 mg% of main mot and 470 mg% of lateral root. Major total amino acids of root were arginine, glutamic acid, major free amino acids of main and lateral root were detected asparagine, arginine, glutamic acid and phenylalanine, respectively. Among the essential amino acids, the content of threonine was the highest (15.62 mg%) in main root and phenylalanine was the highest (12.67 mg%) in lateral root.
