초록

마로부터 전분의 추출조건을 확립하기 위해 아스코르브산, 메타중아황산나트륨, 탄산수소나트륨 및 탄산나트륨을 전분추출용액으로 하여 추출된 전분의 추출수율과 물리화학적 특성을 조사하였다. 증류수를 이용하여 마로부터 전분을 추출할 경우 추출수율은 본 연구에서 적용한 전분추출용액을 사용할 때의 약 30% 수준으로 매우 낮았으며, 전분추출과정 중 갈변현상의 발생으로 최종적인 마 전분이 회백색을 띄어 전분소재로 적합하지 않았다. 마 전분의 추출수율은 전분추출용액에 따라 통계적으로 유의성은 없었으나 탄산수소나트륨 용액을 사용한 경우 가장 높았으며, 아스코르브산 용액을 사용한 경우가 다음으로 높은 추출수율을 나타내었다. 마 전분들의 조단백질 함량은 대표적인 서류전분들에 비해 높은 수준이었으나 총 전분함량은 유사하거나 높아 전분소재로서 활용이 가능한 것으로 보인다. 겉보기 아밀로오스 함량은 산성 전분추출용액들에 의해 제조된 마 전분들이 염기성 전분추출용액들에 의한 것보다 낮은 수준을 나타내었다. 마 전분의 입도분포와 평균입도는 전분추출용액에 따라 큰 차이를 나타내지 않았다. X선 회절패턴은 전형적인 C형 결정구조를 나타내었으며, 염기성 전분추출용액들을 사용한 경우 상대적 결정도는 감소하였다. 용해도는 전분추출용액에 따른 특정 경향을 나타내지 않았으나, 팽윤력은 산성에 비해 염기성 전분추출용액들을 사용하였을 때가 높았다. 마 전분들의 호화온도는 대체로 유사한 수준이었으나 호화엔탈피는 산성에 비해 염기성 전분추출용액들을 사용하였을 때 감소하였다. 페이스팅 점도는 탄산나트륨, 메타중아황산나트륨, 탄산수소나트륨, 아스코르브산 용액들에 의한 마전분들의 순서로 증가하였다. 특히 마 전분들의 강하점도(breakdown viscosity)와 치반점도(setback viscosity)는 염기성 전분추출용액들을 사용하였을 때 증가하는 양상을 나타내었다. 전반적으로 아스코르브산 용액을 이용하여 제조된 마 전분은 추출수율이 상대적으로 높고, 총 전분 함량도 풍부하며, 온도프로파일에 따른 페이스팅 점도의 변동이 상대적으로 적다. 또한 본 연구에서 적용된 전분추출용매들에 비해 아스코르브산은 마 전분 내에 전분추출용액의 잔류에 대한 안전성 문제가 없다. 결과적으로 마로부터 마 전분의 추출을 위한 전분추출용액을 위해서는 아스코르브산을 사용하는 것이 적절한 것 같다.

This study investigated the influence of starch extraction (ST-EX) solutions on the extraction yield and characteristics of Chinese yam (CY) starches from domestic Dioscorea batatas. Ascorbic acid (VitC), $Na_2S_2O_3$, $NaHCO_3$, and $Na_2CO_3$ were used as ST-EX solutions (0.4%, w/v). The extracted CY starches were examined for ST-EX yield, chemical composition, size distribution, X-ray diffraction, solubility, swelling power, gelatinization, and pasting viscosity. The highest ST-EX yield was obtained from $NaHCO_3$, followed by VitC. Lower protein content, relative crystallinity, and gelatinization enthalpy were found in CY starches from alkaline ST-EX solutions ($NaHCO_3$ and $Na_2CO_3$). Size distribution and gelatinization temperature did not generally differ for CY starches from the different ST-EX solutions. Pasting viscosities increased in the order from $Na_2CO_3$ > $Na_2S_2O_3$ > $NaHCO_3$ > VitC ST-EX solutions. Thus, VitC may be most appropriate to extract CY starch from Dioscorea rhizomes, considering its ST-EX yield, total starch content, and variation in pasting viscosity.
