  第二:体格检查

  Second: physical examination

  (1)千粒重35 ~ 45g。

  (1) 1000 grain weight 35 ~ 45g.

  (2)大于2.5mm的麦粒为一级大麦,2.2-2.5mm的麦粒为二级大麦。初级和次级大麦都可以用作酿酒原料。下腹部直径2.2毫米是二次大麦,不用于酿造。

  (2) the grain larger than 2.5mm is the first grade barley, and the grain 2.2-2.5mm is the second grade barley. Both primary and secondary barley can be used as brewing materials. The lower abdomen, 2.2 mm in diameter, is secondary barley and is not used for brewing.

  (3)胚乳状态:胚乳切片为粉状白色质粒,淀粉含量高,吸水性好,易分解。胚乳部分为玻璃体或半玻璃体,吸水差,淀粉不易分解。

  (3) endosperm state: the endosperm section is powdery white plasmid with high starch content, good water absorption and easy decomposition. Endosperm part is vitreous or semivitreous, poor water absorption, starch is not easy to decompose.

  (4)发芽力和发芽率发芽率是指3天内发芽的百分率,要求不低于90%。发芽率是指5天内发芽的百分率,要求不低于95%。

  (4) germination power and germination rate germination rate refers to the percentage of germination within 3 days, which shall not be less than 90%. Germination rate refers to the percentage of germination within 5 days, which shall not be less than 95%.

  Last: chemical test

  (1)大麦含水率应小于13%,否则难以贮存。

  (1) the moisture content of barley should be less than 13%, otherwise it is difficult to store.

  (2)提取物的质量分数一般要求在72% ~ 80%(干物质计数)以上,与淀粉的质量分数相差约14.7%。

  (2) the mass fraction of the extract should be over 72% - 80% (dry matter count), which is about 14.7% different from that of the starch.

  (3)蛋白质的质量分数一般要求为9% ~ 12%(绝对干物质),辅料用量可达13.5%。

  (3) the content of protein is 9% - 12% (absolute dry matter), and the dosage of excipients is 13.5%.
