以籼稻黄华黏为原料,研究离心和胶辊2种不同砻谷方式所得糙米的发芽情况,并从吸水率、电导率和扫描电镜4个方面对2种砻谷方式所得糙米进行比较并分析其原因。结果表明,离心砻谷所得糙米的发芽率显著高于胶辊砻谷所得糙米。同时,糙米浸泡0～2h的吸水率和0～12h的电导率值均是前者明显高于后者。从电镜图比较得知,离心砻谷所得糙米胚部表面纹路有被磨平的痕迹,胶辊砻谷机所得糙米胚部表面纹路深。离心砻谷所得糙米的发芽情况优于胶辊砻谷的根本原因是前者得到的糙米胚部表层结构受损,使得糙米吸水能力增强、胚芽更容易冲破皮层以及氧气进入糙米的阻力减小。该结论对于发芽糙米的高效生产有着重要的...

Effect of centrifugal and rubber roll hulling methods on brown rice was investigated,including germination,water absorption,electric conductivity and SEM micrograph.The results showed that the germination rate of brown rice obtained by centrifugal hulling was significantly higher than the brown rice by hulling.Meanwhile,the water absorption in the range of 0 to 2 h and the conductivity value of in the range of 0 to 12 h of the former were also clearly higher than those of the latter.By scanning electron microscopy（SEM） observation,the surface...
