人工香精的原理

原來我們喝下去的茶也有可能是假的?

人工香精是由多種化學合成物所製作而成,不只可以增加茶湯風味,還能降低苦澀感,但喝多了對身體健康有害,可能出現過敏等不適症狀,甚至會對肝臟與腎臟的代謝造成負擔,同時也無法得到茶葉原本豐富的營養。添加人工香精的茶香味濃烈刺鼻,散發不自然的香味,無法聞到茶葉原來的青草味,泡茶時,如果在很短的時間內就散發茶香,或是前一兩泡很香,但第三泡以後落差很大,甚至是開封很久以後,茶葉還是很香的話,則表示這些茶葉可能是添加了人工香精。喝茶時,感覺香氣在鼻腔中環繞、較為輕浮,喝起來不會有潤口的感覺且感到口乾舌燥,同時喝完的手搖飲料空杯,隔了一段時間後還是散發出很香或是濃郁刺鼻的味道,也很有可能是添加了人工香精,因為天然茶葉的香氣則是扎實且穩重,而且基本上天然茶葉泡出來的茶湯香氣不會存留於杯中[1-2]。

另外,使用茶精來製作飲料,對飲料業者而言,不只製作簡單,還能減少許多時間與成本,以1000c.c的綠茶茶精來說大約可以泡出1430杯綠茶茶精主要以酯類為主,各種茶精應有盡有,只要將幾滴茶精倒進水中,攪拌一下即可完成一杯茶,天然茶葉泡的茶香氣會一直變化,有前中後韻,口感甘醇順口,也因為天然茶葉含有自然的胺基酸,沖泡時,泡沫活性不同,容易散開且不均勻,而由茶精所泡的茶香氣與味道不會改變,濃烈刺鼻且持久不散,也因為是由化學物質沖泡而得,所以會形成氨基乙酸,泡沫較細緻綿密。將茶放置約3-4小時後,若茶表層有一層垢且味道變質,則是沒有添加茶精,反之若放置很久一段時間之後,味道完全沒有變質,則代表是添加茶精,通常由茶精所泡的茶在香氣與味道方面都比用天然茶葉所泡的茶還要香且濃,不過若是茶精萃取到茶葉中不好的物質,例如農藥或病蟲害殘留的化學物質,則茶精可能也會保有那些有害的成分[3-4]。

不管是人工香精或是茶精,都是屬於化學添加物,吃多了對身體健康有很大的影響,因此盡量少接觸較為適當。如果真的想要喝茶的話,澄翠茶藝推薦還是用天然茶葉,由自己沖泡最好,不只為自己健康把關,也能喝進許多茶葉豐富的營養,還能在茶湯最新鮮的時刻享用最佳的茶湯品質,同時達到身體與心靈的滿足,不是很棒嗎?

The theory of artificial flavoring

Artificial flavoring consists of several chemical compositions, which can increase the taste of tea and reduce bitterness. However, it would harm health as well. Artificial flavoring could result in allergy and the problems of liver and kidney. Meanwhile, we can’t fully gain the nutrition of tea if drinking tea with artificial flavoring. Tea added artificial flavoring smells pungent and unnatural. Tea could be added artificial flavoring if tea scents shortly, scents at first but decrease after, or even still scents for a long time. In addition, tea added artificial flavoring could make the fragrance smell frivolous, taste thirsty when drink tea, and the empty cup still scent for a long time. Compared to tea added artificial flavoring, natural tea smells natural, and the scent won’t retain in the empty cups[1-2].

On the other hand, the way to use tea extract to make tea is easy and can reduce a lot of time and cost for beverages stores. For example, 1000c.c tea extract of green tea can make about 1430 cups of green tea. Tea extract is composed of esters, and there are plenty of kinds of tea extract. Just put a few drops of tea extract into water, stir a bit, then tea is finished. The scent of natural tea would change with the gradual smell, and have the sweet aftertaste. Meanwhile, natural tea contains natural amino acids, and the foam would spread and is uneven due to their different activity. In comparison, the smell and the taste of tea brewed by tea extract wouldn’t change. Usually it smells strong and pungent. Tea brewed by tea extract would form glycine, and the foams are dense. Tea without tea extract would deteriorate with the dirt on the surface if put aside for a long time. However, tea brewed by tea extract won’t be worse if place for a long time. It generally smells more fragrant and tastes heavier compared to natural tea[3-4].

Tea extract could contain ingredients which may be harmful for health if drawing out some bad materials from tea, such as pesticide and the pest[3-4]. Therefore, both artificial flavoring and tea extract would have a great influence on health. It is advised not to frequently drink tea with artificial flavoring and tea extract. It you do really want to drink tea, LittoTea suggests that you brew tea by yourselves with natural tea, which would help us gain rich nutrition and benefit our health more. Meanwhile, we can drink the freshest tea to satisfy both physical and mental health.
