Abstract

Some properties of starch isolated from gamma-irradiated chestnut at doses of $0{\sim}0.45\;kGy$ were investigated. The treatment increased the water-binding capacity and decreased intrinsic viscosity and amlyograph viscosities. Other properties including swelling power and solubility at $80^{\circ}C$, blue value and percent transmittance of starch dispersion were essentially not affected by irradiation at sprout-inhibition dose.

밤을 $0.15{\sim}0.45\;kGy$ 범위의 감마선으로 처리하고 이로부터 분리한 전분의 성질을 조사하였다. 감마선 처리에 따라 전분의 물결합 능력은 다소 증가되었고, 고유점도와 아밀로그래프 점도는 일정하게 감소되었다(r=-0.950). 그러나 전분의 팽윤력, blue value 및 광투과도는 발아억제 선량범위에서 변화되지 않았다.
