单宁

There are two groups of hydrolysable tannins: gallotannins and ellagitannins on the basis of structural characteristics.

根据水解单结构特性差异，又将其分为棓单和鞣花单。

Endowed with intensive structure and soft palate, it leaves long dryish tastes in finish.

单结构紧密，余韵悠长，干爽，有持续果香。

Kinetic characteristics of valonia tannin biodegradation using natural microorganism groups were studied.

研究了微生物菌系对橡单生物降解能力。

Tannase hydrolyses the ester bonds and depside bonds in gallic acid tannins to release gallic acid and glucose.

摘要单酶可水解没食子酸单酯键和缩酚羧键，生成没食子酸和葡糖。

Off dry on the medium bodied palate.Quite herbal but overall lacking any class.Lean and stemmy.

单酸味道强烈，后味还交织着一淡淡草药香味，清新爽口。

Ellagitannin, the main tannin in oak, is an important factor influencing the quality of grape wine in oak barrel.

鞣花单是橡木主要单,是影响橡木桶贮葡量重要因素之一。

The conversion film is probably constituted of amorphous and pored alloying tannate chelate.

这种转化膜很可能是由有一定孔隙非晶态合金单酸膜层构成.

The tannin makes this grape very suitable for ripening on oak barrels.This makes the bitter tannin souple and soft.

单是这种葡酿制非常适合在橡木桶成熟， 这可以使单苦涩感变更柔顺，圆润。

Effects of single strain cultivation and co cultivation of strains on biodegradation of valonia tannin were investigated.

以橡单为原料,通过培养、分离筛选出了14种菌株。

Modified larch tannin was prepared by grafting copolymerization and sulfoalkylation, and successfully used as retanning agent, possessing good water solubility and enhanced penetration rate.

利用接枝共聚和磺烷基化方法对落叶松单改性。

The application that waits for Lin Hua product as to colophony, terebinthine, Chan Ning, raw lacquer, tung-oil, white wax, pigment also has long history.

至于松香、松节油、单、生漆、桐油、白蜡、色素等林化产品应用也具有悠久历史。

The biological stability(assessed by AOC), had close relation to tannin value, and was increasing with the tannin value, but it had no velation to the pore size distribution.

滤池出水生物稳定性与单酸值有密切关系，单酸值越低，出水生物稳定性越高，与孔径分布则没有关系。
