Effect of ${\beta}-Glucan$ on Gelatinization of Barley Starch

${\beta}-Glucan$이 보리 전분의 호화에 미치는 영향

  • Published : 2003.08.01


The effect of ${\beta}-glucan$ on gelatinization of barley starch was studied. By the rapid visco-analyzer measurement, gelatinization of starch became rapid and viscosity increased largely on the RVA pattern by addition of ${\beta}-glucan$ to starch. The results of differential scanning calorimeter showed that molecular structure of starch was getting stabilized through shifting up of gelatinization temperature and increase in enthalpy by addition of ${\beta}$-glucan. X-ray diffraction pattern also showed the same results as differential scanning calorimeter. But it was revealed that addition of ${\beta}$-glucan to starch didn't affect characteristics such as microscopic observation, solubility, swelling power, and iodine binding properties during gelatinization of starch.

${\beta}$-Glucan이 보리 전분의 호화양상에 미치는 영향을 조사하였다. RVA 분석에 의하면 ${\beta}$-glucan의 첨가에 의해 전분은 RVA 상에서의 호화개시가 빨라지고 점도가 크게 증가하는 것으로 나타났다. 또한 DSC 분석 결과 ${\beta}$-glucan 첨가에 의해 전분입자가 안정화되어 전분의 호화개시 및 peak 온도가 증가하였으며, X-선 회절 양상 결과에서도 ${\beta}$-glucan 첨가에 의해 전분의 결정성이 증진되어 DSC 분석과 동일한 결과를 나타내었다. 그러나 ${\beta}$-glucan 첨가는 전분의 호화과정 중의 전분입자의 형태 및 amylose, amylopectin의 용출양상과 팽윤력, 용해도 등의 호화시 발생하는 특성의 변화에는 거의 영향을 미치지 않는 것으로 나타났다.
