淀粉

In the production of corn starch,adopt craftwork of 5~12 grades fibre adverse current separate and abstersion,increase the output and quality of corn starch.

在玉米淀粉的生产过程中，采用5～12级纤维逆流分离与洗涤工艺，以提高玉米中淀粉的回收率，提高商品淀粉的品质。

Cloning of the Schwanniomyces occidentalis α-amylase and high expression in S.cerevisiae.The E.coli / yeast shuttle plasmid YCEpl partial library of Schwanniomyces occidentalis DNA was constructed and α-amylase gene fragments were screened in Saccharomyces cerevisiae by amylolytic activity.Several transformants with amylolysis were obtained and one of the fusion plasmids has about 5.0 kb inserted DNA fragment.It contains the upstream and downstream sequences of α-amylase gene from S.occidentalis .

以E.coli/yeast穿梭质粒YCEp1为载体构建西方许旺酵母部分基因组文库，在大肠杆菌中扩增后提取混合质粒DNA，经电转化非缺陷标志酒精酵母 AS.2.1364，在YPDS平板(含1%葡萄糖和1%可溶性淀粉)上用淀粉水解活力筛选含水解淀粉的阳性转化子，从阳性转化子中分离重组质粒证实含5.0kb的插入片段，用α-淀粉酶基因两端序列设计的引物PCR扩增及扩增片段序列分析证实该片段中含有α-淀粉酶全部编码序列。

The main ingredient is rice starch, which contains 17 percent amylose, amylopectin 83%.

的主要成分是大米淀粉，其中载有百分之十七直链淀粉，支链淀粉83％。

All the resistant starches were found to be of high molecular weight containing amylopectin and amylose.

所有的抗性淀粉图谱显示分子量很高说明都含有支链淀粉和直链淀粉。

It is not a single molecule, but a mixture of amylose (straight chains of glucose subunits) and amylopectin.

淀粉是葡萄糖的多聚体，不是一个单独的分子，而是直链淀粉和支链淀粉的混合物。

Starch makes up about 90% dry matter content of milled rice , which is divided into amylose and amylopectin .

淀粉是稻米的重要组成部分，占精米干物质的90％左右，可分为直链淀粉和支链淀粉。

The structure and content of rice grain starch was analyzed, and the change in amylase and amylopectin content and structure of rice grains was discussed during storage.

分析了稻米淀粉的结构，讨论了储藏对稻米直链淀粉和支链淀粉含量与结构的影响。

This hindered starch swelling and subsequent release of amylose and amylopectin hence lower expansibility.

这阻碍了淀粉溶胀以及随后的直链淀粉和支链淀粉的释放从而使膨胀性下降。

The results showed that amylose content, amylopectin content and total starch content increased continuously during grain filling stage.

结果表明，适当增加施氮量，可提高高淀粉高粱品种总淀粉含量和支链淀粉含量。

Natural starch from the amylose and amylopectin component.

天然淀粉由直链淀粉和支链淀粉组成。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
