초록

아마란스를 식품가공용 중간소재로 개발하기 위해 아마란스 종실을 1차 가공처리한 후 전분과 각 가루의 가공특성을 조사 하였다. 아마란스는 전분, 무처리(UT), 탈지(DF), 발아(GM), 로 스팅(RT), 팽화(POP), 압출성형(EK1, EX2)하여 시료로 사용하였다. 아마란스 가루의 결정형은 전형적인 A형을 보였고 탈지, 발아, 로스팅 처리에 의한 결정형과 결정강도의 변화는 없었다. 그러나 팽화 처리와 압출성형에 의해서는 결정형이 사라졌다. 시료의 물 결합능력은 가공방법에 따라 차이가 있어 POP 시료의 물 결합능력이 740.3%로 가장 컸고, EX1이 35.5%로 가장 낮았다. 아마란스 가루의 광투과도 특성은 $60^{\circ}C$에서 차이가 있어 RT, POP, EX1, EX2 시료의 광투과도가 높게 나타났다. RVA로 측정한 아마란스 시료의 호화온도는 POP와 EX1, EX2를 제외하고 $68.1-73.0^{\circ}C$이었고, 피크점도는 GM이 31.6 RVU, RT가 401.1 RVU로 큰 차이가 있었다. DSC결과 또한 RVA 결과와도 일치하여 POP, EX1, EX2는 milling endotherm이 나타나지 않았다.

Processed foods were developed using amaranth starch and flours. Amaranth seeds were untreated (UT), defatted (DF), germinated (GM), roasted (RT), popped (POP), and extruded (EX1 and EX2). Amaranth flours showed A-type pattern on X-ray diffractograms, while crystallinity was not observed in POP, EX1, and EX2. POP and EX1 showed highest (740.3%) and lowest (38.5%) water-binding capacities, respectively. Transmittances of RT, POP, EX1, and EX2 flour suspensions were higher than those of others. Transmittance of amaranth starch and flours differed with processing methods. RT, POP, EX1, and EX2 showed higher transmittance at $60^{\circ}C$. Initial pasting temperature of amaranth flours by RVA were $68.1-73.0^{\circ}C$, and peak viscosities of GM and RT were 31.6 and 401.1 RVU, respectively. Melting endotherms of POP, EX1, and EX2 were not observed in DSC thermograms.
