1) diacetyl content
双乙酰含量
1.
pressure less than 300 MPa could advance decomposition of α-acet lactate and reduction of diacetyl and effectively reduce diacetyl content,and pressure more than 300 MPa would prolong the reduction of diacetyl and increase diacetyl content;3.
②压力小于300 MPa时,促进清酒中α-乙酰乳酸的非酶分解及双乙酰的还原反应,具有降低双乙酰含量的作用;而压力大于300 MPa,会相对延缓双乙酰的还原,导致双乙酰含量的反弹。
3) acetylation value
乙酰基含量
1.
The acetylation value and substitution degree of these starches were determined with chemical analysis methods and IR spectrum.
用化学分析方法和红外光谱法测定了在不同 p H值下制备的一系列醋酸酯淀粉的取代度和乙酰基含量 ,获得了 p H值对淀粉酯化反应的影响规律 ,并解释了该规律 。
4) ureide content
酰脲含量
1.
Relation between ureide content and nitrogenase activity in soybean;
