单宁

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的非晶态合金宁酸膜层构成.

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

研究了微生物菌系对宁的生物降解能力。

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

宁酸味道强烈，后味中还交织着一丝淡淡的草药香味，清新爽口。

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

宁结构紧密，余韵悠长，干爽，有持续的果香。

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

宁为原料,通过培养、分离筛选出了14种菌。

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

摘要宁酶可水解没食子酸宁中的缩酚羧，生成没食子酸葡萄糖。

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

宁是这种葡萄酿制的酒非常适合在木桶中成熟， 这可使宁的苦涩感变的更柔顺，圆润。

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

鞣花宁是木中的主要宁,是影响木桶贮葡萄酒质量的重要因素之一。

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

根据水解宁结构特性的差异，又将其分为棓宁鞣花宁。

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

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、宁、生漆、桐油、白蜡、色素等林化产品的应用也具有悠久的历史。

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.

滤池出水的生物稳定性与宁酸值有密切关系，宁酸值越低，出水的生物稳定性越高，与孔径的分布则没有关系。
