| 5. | The inhibition of trehalose for the retrogradation of sticky rice starch was studied 摘要本文主要研究了海藻糖对糯米粉的回生抑制作用。 |
| 6. | The microstructure indicated that the structure of modified rice starch vanished after extrusion 超微结构表明挤压法制备的大米变性淀粉的淀粉结构已经消失。 |
| 7. | It was found that replacing part of granulated sugar in the complex solution of granulated sugar and sticky rice starch with trehalose could be effectively stay the course of retrogradation 研究发现,在含有糯米粉、白砂糖的复合体系溶液中,用海藻糖替代部分白砂糖,能有效地延缓回生的进程。 |
| 8. | The solubility of acetylated rice starch and cross - linked rice starch on extrusion increased rapidly , paste temperature disappeared , which demonstrated both modified starches had the characteristic of prepaste starch 挤压法制备的乙酰化大米淀粉和交联大米淀粉的溶解度大幅增加、糊化温度消失,说明挤压法制备的两种变性淀粉还有预糊化淀粉的特性。 |
| 9. | Detailly , it was ( l ) to isolate and construct high efficiency expression vector of rice starch branching enzyme gene sbe2b and ( 2 ) to establish a high - effecient rice transformation system . total rna was extracted from maize endosperm 15dap ( days after pollination ) . and cdna of sbe2b was obtained through rt - pcr . sequencing result showed that the full length cdna was 2 . 4kbp , coding for 800 amino acids , with estimated mw 93kd 本研究从授粉15天左右的玉米胚乳中提取了总rna ,采用rt - pcr方法,克隆了玉米胚乳的淀粉分支酶基因sbe2b ,测序结果表明,玉米胚乳sbe2b的cdna全长为2 . 4kb ,编码800个氨基酸,推测的氨基酸的分子量为93000d ,该序列与genbank中登录号为af072725的玉米sbe2b的cdna序列有98的同源性,与水稻、大麦、小麦等禾本科植物的有关淀粉分支酶的dna序列都有极高的同源性。 |
| 10. | However , the processing quality and food quality of hybrid rice is not good due to high amylose content and hardness , low gel viscosity and bad mouthfeel etc . these problems were improved through regular breeding methods but it was only slightly . the main aim of this study was to modify rice starch quality by molecular biology methods 然而,在杂交稻中许多品种存在品质不优的问题,尤其是直链淀粉含量太高,其蒸煮品质上表现为粘性小,硬度大,口感不好等问题,采用常规育种的方法虽然取得了一些进展,但进程太慢,效果不理想。 |
