与aldehydes相关的网络例句 [注：此内容来源于网络，仅供参考]

After cooking, ketones increase, 3-penten-2-one, 1-penten-3-one and 2-nonanone contributed the good flavor. At the same time, cooking reduced the acids and ringed compounds, which was benifical for the flavor. Although the content of aldehydes didn't change significantly, but the contents of some aldehydes, such as benzaldenyde, heptanal, nonyl aldenhyde lilac aldehyde and 4Z-heptenal, which contributed good flavor to the cooked oyster, increased.Maillard reaction was used to improve the flavor of the flavor product from oyster.

对于生牡蛎，烃类以及1-辛烯-3-醇、4-壬烯醛、2-辛醛等会对风味产生较大的影响；在煮制后的牡蛎中，酮类的数量增加，并大多贡献出美好的风味，其中3-戊烯-2-酮、1-戊烯-3-酮、2-壬酮对煮制牡蛎的风味具有好的作用：煮制会使酸类和带有不良风味的环状化合物的数量减少；醛类的数量和含量在煮制前后虽然没有太大的改变，但是苯甲醛、庚醛、壬醛、丁香醛、4-Z庚烯醛等可以产生良好风味的物质含量增加，贡献了煮制后牡蛎的美好风味。

For the saturated aromatic aldehydes with malononitrile and barbituric acidit, the reaction was found to proceed very efficiently at room temperature giving excellent yields under ultrasonic irradiation, while for α,β-unsaturated aldehydes as well as p-phthalaldehyde with malononitrile and barbituric acid the reaction also proceeded smoothly at room temperature with good yields.

在超声波辐射下，不仅饱和芳香醛与丙二腈、巴比妥酸的一锅反应在室温下能高收率地进行，而对于α，β-不饱和醛以及二元醛与丙二腈、巴比妥酸的一锅反应也能在室温下顺利进行，获得较高的收率。
