In a preferred embodiment of the present invention, the tannase is recycled and in that case higher initial levels of tannase are used.在本发明的所选用的具体操作中,丹宁酶被循环使用,因而在一开始要使用高剂量的丹宁酶。
The obtained hot tea extract is then cooled to a temperature, which make it suitable for the tannase treatment.把获得的这种热水提取物冷却到一个适合进行丹宁酶处理的温度。
The temperature at which the treatment is carried out may, dependent on the tannase type, vary from 20 to 80 c.处理的温度可因丹宁酶类型的不同而在20-80摄氏度之间变化。
An enzyme level ranging from about 0.5 to 500 or more tannase units (determined as hereinbefore described) per gram dry weight of tea may be used.酶的用量为每克干茶叶用0.5-500或更多的丹宁酶单位(用如前所述的方法测定)。
Although the tannase treatment does give a certain amount of solubilisation of the tea cream constituents, the extract is still turbid at 5 c.尽管丹宁酶的处理确能溶解一部分茶膏成分,但在5°C时,这种处理过的茶浸提物仍会浑浊。
Although in principle a good quality of tea extract is obtained by the combination of treating tea extract with tannase followed by an UF treatment,虽然用丹宁酶及UF综合处理茶叶提取物,原则上可以得到高质量的茶叶提取物。
