A Method for Observing Epidermis Stoma by Boiling and Tearing Epidermis from Leaf;

用煮沸撕取法观察表皮气孔的方法

In addition to CIP and hot water preparation,mash temperature rise and wort temperature rise and wort boiling consumed most of heat energy in beer brewing.

啤酒生产过程的热能消耗除CIP和热水制备外,主要耗能集中在醪液升温、麦汁升温以及麦汁煮沸等工段。

The prolonging of b oi ling time and the enhance of boiling temperature could decrease the content of c oncretionary nitrogen in wort but would increase wort colority on the other hand .

延长煮沸时间和增加煮沸温度可降低麦芽汁凝固氮含量,但会增加麦汁色度;单宁的理想添加浓度为60mg/kg;添加复合硅胶可吸附沉淀部分蛋白质颗粒,降低啤酒色度,提高啤酒非生物稳定性。

The result shows it is not suitable for the alcohol-testing(75%,V/V) to take the place of the boiling testing and acidity measuring,as there is no parallel relationship among alcohol testing,boiling testing and acidity measuring still needed.

结果表明:75%(V/V)酒精试验与煮沸试验、酸度测定并无对应关系,得出75%(V/V)酒精试验法不宜替代煮沸试验和酸度测定作为生鲜牛奶热稳定和新鲜度的评定方法的结论。
