August 6, 2008 Could this new electronic wine-tasting tongue challenge the finest wine tasters in the world? Invented by European scientists, this handheld device has a multi-sensor chip which senses distinctive characteristics of wine varieties. By analyzing the sugar content, acidity and alcohol, the machine can also determine the year and grape variety of the sample and instead of waiting days for laboratories to analyze wine samples, wine industry specialists will be able to get a sample result at the touch of a button.

這個最新的品酒電子舌頭可否挑戰世界上最優秀的品酒家呢?歐洲一群科學家發明的這項掌上型的設備,具有一個多功能的感應晶片,它可以感應出各葡萄品種的鮮明特色。透過分析其糖含量,酸度及酒精度,這台機器也可以判斷出樣本的葡萄品種和年份,取代過去實驗室得花好幾天來分析葡萄酒樣本的等待。葡萄酒業的專家只要按一下按鈕,就能夠得到樣本的測試結果。
Invented by Cecilia Jiménez-Jorquera and colleagues from the Barcelona Institute of Microelectronics , Spain , this handheld device has a multi-sensor chip which senses distinctive characteristics of wine varieties.
這個掌上型、具多功能感應晶片,可以感應出各葡萄品種的鮮明特色的儀器,是由西班牙巴塞隆那微電子科研所的Cecilia Jiménez-Jorquera和她的同仁們所共同發明的。
“the device could be used to detect frauds committed regarding the vintage year of the wine, or the grape varieties used,” according to Jiménez-Jorquera. The wine-tasting tongue is portable, cheap to manufacture, is capable of being programmed to test for other parameters and can be trained to test new varietals.
“該裝置可用於有關葡萄酒年份欺瞞行為,或關於該葡萄酒所使用的品種的偵測” Cecilia Jiménez-Jorquera說。這個wine-tasting tongue儀器,便於攜帶、量產成本低,而且能夠設定其他參數的計劃,也可以被訓練用來測試葡萄的新品種。

Electronic integrated multisensor tongue applied to grape juice and wine analysis

An integrated multisensor composed by six ISFET devices selective to common ions and heavy metals combined with a flow injection analysis (FIA) system has been applied as an electronic tongue to grape juice and wine sample analysis. The data obtained for several grape and wine variety samples analysis have been treated using multiparametric tools like principal component analysis (PCA) and soft independent modelling class analogy technique (SIMCA) for the patterning recognition and classification of samples and partial least squares (PLS) regression for quantification of several parameters of interest in wine production. The results obtained have demonstrated the potential of using those multisensors as electronic tongues not only for distinguishing the samples according to the grape variety and the vintage year but also for quantitative prediction of several sample parameters

電子舌(Electronic Tongue)的應用越來越廣泛,最新的研究是用來分辨紅酒的葡萄品種及年份。有關研究只屬初步階段,但研究人員希望這種電子舌有朝一日可以取代人舌,成為重要的品酒器具,用來分辨贋品。 電子舌的原理是通過感應器來識別、鑑定液體中的致味分子。它主要是透過設於名為多元感應器的單一矽晶片上的眾多合成薄膜,每一個薄膜都有不同的感應器,對不同的化學成份有不同的感應程度,從而分辨出各種葡萄品種,並可以分出紅酒的年份。 現時電子舌已可以分辦出四種不同葡萄品種,分別是Airén、Chardonnay、Malvasia及Macabeu ,並可以區分同一品牌紅酒的不同年份,即2004年及2005年。 進行有關研究的巴塞隆那微電子學研究院的研究人員日默內.霍爾克拉指出,這種儀器和人類舌頭原理類似,對五種不同味道:酸、甜、苦、鹹及鮮味,非常敏感,可以逐一分辦出來。
又是電子!!!Oh my goodness! 還要代替人舌!

看著這報道,令我聯想到早兩天看罷環保意識濃厚的動畫電影Wall-E,此片寓意深遠,所有對地球還有一絲責任心的人應看看。不在此透露太多劇情,親身到戲院感受製片人的心意會更好。
說回這電子舌頭,研究目的是「分辨贋品」 - 很大條的道理!再讀下去卻還是「這種儀器和人類舌頭原理類似」 - 資料輸入的始終是人。既然人可以把年份分別輸入電子舌頭記憶體,即是人舌也應能分辨。人體構造精密無比,最基本的品味也要交託給電子儀器,試問活着還有甚麼意義?那麼選美也只須依賴電腦以黃金面譜、黃金身段計分,一scan便知國籍年齡健康,省下肉眼觀察,行嗎?或者...傳宗接代這種費勁的運動也交與電器吧,肯定有仔生.....但,這個世界你還住得下去嗎?
