中国茶道的四大流派

过去的茶馆,深谙和气生财的道理,处处与人方便。如天津等地的茶楼,数人同去可以一壶数杯,也可以自备茶叶由茶楼代泡。茶容中途离开,可以保留座位,回来接着喝。不过,各地规矩稍有不同：北京外出时是将茶碗扣在桌上,吩咐堂倌一声;绍兴是将茶杯盖仰天放在桌上,表示“暂时离开,请勿占位”。     

中国茶与日本茶道

眼下正是采茶之际,使人很容易谈起茶。当我第一次听留学归来的好友大谈日本茶道时,感到新奇的同时,也非常佩服日本人守规矩,有礼貌。年初我去南方的几座城市出差,看到日本式的茶道馆在繁华的商业区越来越多,然而里面的生意却不错,这才引起我的注意。 说起茶,日本人第一个要感谢中国有位叫徐福的人。     

茶道人生

茶之为饮,却无关乎于渴。这是我读了几篇关于茶的文章之后,瞬间得到的灵感。喝茶是一种休闲,休闲时一杯茶,一声琴,一窗竹,一卷书,一个人,方是人生惬意时。匆忙时,饥渴时,只供水,勿奉茶,方是供者施,求者需,更免得使供者一腔美意尽飘零,又陷求者于俗。

沉浸茶乡结茶缘得品茶香为茶人

我一直固执地认为,爱喝茶的人要么外表斯文温文尔雅、要么举止文雅仙风道骨。在见到一品古道范承胜先生时,我的"固执"得以应验,这次见吴秘书长,我很庆幸,我的"固执"又一次"巧合"地吻上了,看来我应该继续"固执"下去……吴锡端,中国茶叶流通协会秘书长,他有着典型的茶人脸庞,一看就是位知者、智者;他是嗅着茶香长大的,与茶的缘分是天定的。要说他的茶缘,且随我一同进入本期的茶奇人物吧!     

Epimerisation of tea polyphenols in tea drinks

The present study was carried out to quantify green tea epicatechin (GTE) derivatives and to investigate the origin of epicatechin epimers present in 18 selected canned or bottled tea drinks. The major GTEs present in tea are (?)‐epigallocatechin gallate (EGCG), (?)‐epigallocatechin (EGC), (?)‐epicatechin gallate (ECG) and (?)‐epicatechin (EC). HPLC analysis showed that the content of total GTEs was lower (16.4–268.3 mg l^?1) in the canned and bottled tea drinks than in tea traditionally prepared as a beverage in a cup or teapot (3–5 g l^?1). The major finding was that they contained higher levels of epicatechin epimers, namely (?)‐gallocatechin gallate (GCG), (?)‐gallocatechin (GC), catechin gallate (CG) and (?)‐catechin (C), than of GTEs, ranging from 7.6 to 331.8 mg l^?1. To investigate the origin of these epimers, GTEs were extracted from longjing green tea and autoclaved at various temperatures for 10–60 min. It was found that at least 50% of GTEs were epimerised to their corresponding epimers when autoclaved at 120 °C for 20 min. It is concluded that epicatechin epimers in tea drinks are not originally present in green tea leaf but are instead derived from thermal conversion of GTEs.

茶树花中茶多酚和茶皂素综合提取技术研究

为了实现对茶树的综合利用,以茶树的花为实验材料,在单因素实验的基础上,采用正交实验方法对茶树花中茶多酚和茶皂素的综合提取工艺进行优化。分析了浸提时间、料液比、浸提温度、乙醇浓度和超声波功率对浸出率的影响。结果表明,乙醇浓度70%,超声波功率350W,浸提温度60℃,浸提时间10min,料液比1∶30g/mL时,茶多酚和茶皂素的综合得率最高,分别达到了28.38%和23.69%。     

蜂蜜茉莉普洱茶饮料工艺的研究

研究了以普洱茶和茉莉花茶为主要原料制备的茶饮料的工艺流程.结果表明,浸提普洱茶和茉莉花茶的最佳工艺参数为:浸提时间15min,茶水质量比1:65,浸提温度85℃,浸提pH值为5.0,离心速度7000r/min,椴树蜜的添加量0.6%,VC的添加量为0.05%,饮料的糖度约为3.9°Bx,135℃瞬时灭菌5s.该饮料最大程度地保留了普洱茶和茉莉花茶的香味,又减少沉淀,茶汤色泽呈红色,澄清透明.     

Chemopreventive effects of tea in prostate cancer: green tea versus black tea

The polyphenol compositions of green tea (GT) and black tea (BT) are very different due to post-harvest processing. GT contains higher concentrations of monomeric polyphenols, which affect numerous intracellular signaling pathways involved in prostate cancer (CaP) development. BT polymers, on the other hand, are poorly absorbed and are converted to phenolic acids by the colonic microflora. Therefore, after consumption of GT, higher concentrations of polyphenols are found in the circulation, whereas after BT consumption the phenolic acid levels in the circulation are higher. The majority of in vitro cell culture, in vivo animal, and clinical intervention studies examine the effects of extracts of GT or purified (-)-epigallocatechin-3-gallate (EGCG) on prostate carcinogenesis. These studies provide strong evidence supporting a chemopreventive effect of GT, but results from epidemiological studies of GT consumption are mixed. While the evidence for a chemopreventive effect of BT is much weaker than the body of evidence with regard to GT, there are several animal BT intervention studies demonstrating inhibition of CaP growth. This article will review in detail the available epidemiological and human clinical studies, as well as animal and basic mechanistic studies on GT and BT supporting a chemopreventive role in CaP.     

茶与茶渣的高值化综合利用

中国既是茶的原产地,也是茶的生产与消费大国,每年由于茶饮料及茶叶深加工产生大量的茶渣,仅仅以简单地丢弃处理而没有被高值化综合利用,既给环境带来了巨大的压力也造成了资源的浪费。茶渣中含有10%至16%粗纤维以及少量的络合态色素、矿物质、氨基酸、茶多酚、咖啡碱等,可以被多种形式地精深加工利用。本文综述了茶渣作为主要配料在作菌类的培养基、动物饲料的添加剂、植物的土壤肥料等方面的应用,以期为茶与茶渣的研究与利用提供参考。
