Amawayini omgunyathi, ubuhlakani bokwenziwa bungakwazi ukudalula imikhonyovu

Umagazini I-Communication Chemistry ishicilele imiphumela yokuhlaziywa kokulebula kwamakhemikhali ewayini elibomvu.

Amanyuvesi ase-Geneva nase-Bordeaux akwazile ukuhlonza, ngokunemba okungu-100%, ilebula yamakhemikhali yewayini elibomvu lezinkampani eziyisikhombisa ezinkulu ezikhiqiza iwayini esifundeni sase-Bordeaux.

Imiphumela yatholwa ngenxa yokusetshenziswa kwe-Artificial Intelligence.

Ukulwa nokukhwabanisa kwewayini

Le miphumela, eshicilelwe kujenali 'Communications Chemistry', ivula indlela amathuluzi amasha angaba khona okulwa nomgunyathi iwayini, kanye namathuluzi abikezelayo okuqondisa ukuthathwa kwezinqumo emkhakheni wewayini. 

Iwayini ngalinye liwumphumela wezingxube ezinhle neziyinkimbinkimbi zezinkulungwane zama-molecule. Ukugxilwa kwawo kuyashintshashintsha ngokusekelwe ekubunjweni kwamagilebhisi, okuncike, futhi, kumvelo, ukwakheka kwenhlabathi, izinhlobonhlobo zamagilebhisi kanye nemikhuba yomenzi wewayini. Lokhu kuhlukahluka, noma kuncane, kungaba nomthelela omkhulu ekunambithekeni kwewayini. Ngokushintsha kwesimo sezulu, imikhuba emisha yabathengi kanye nokwanda kokwenziwa kwewayini, isidingo sokuba namathuluzi asebenzayo okunquma ukuthi angobani amawayini manje sesibaluleke kakhulu.

I-chromatography yegesi

Enye yezindlela ezisetshenziswayo 'i-gas chromatography', okuhlanganisa ukuhlukanisa izingxenye zengxube ngokuhambisana phakathi kwezinto ezimbili. Le ndlela, ngokuqondile, idinga ukuthi ingxube idlule ithubhu elincane kakhulu elingamamitha angu-30 ubude, lapha izingxenye ezihambisana kakhulu nezinto ze-tube zizohlukana kancane kancane kwezinye; ukuhlukaniswa ngakunye kuzobe sekurekhodwa 'yi-mass spectrometer', ezokhiqiza i-chromatogram, ekwazi ukuthola 'iziqongo' ngaphansi kokuhlukana kwamangqamuzana.

Endabeni yewayini, ngenxa yama-molecule amaningi aliqambayo, lezi ziqongo ziningi kakhulu, okwenza ukuhlaziya okuningiliziwe nokuphelele kube nzima kakhulu. Ngokubambisana nethimba lika-Stephanie Marchand, ovela ku-Institute of Vine and Wine Sciences yaseNyuvesi yase-Bordeaux, iqembu locwaningo lika-Alexandre Pouget lithole ikhambi lale nkinga, elihlanganisa ama-chromatogram namathuluzi obuhlakani bokwenziwa.

I-Chromatograms kanye Nobuhlakani Okwenziwayo

Ama-chromatograms avela kumawayini abomvu angama-80 avela kumavintage ayishumi nambili, phakathi kuka-1990 no-2007., kanye nezizinda eziyisikhombisa esifundeni saseBordeaux. Le datha eluhlaza yabe isicutshungulwa kusetshenziswa ukufunda ngomshini, inkambu yeubuhlakani bokufakelwa lapho ama-algorithms afunda khona ukukhomba amaphethini avelayo emaqenjini olwazi. Indlela isivumela ukuthi sicabangele ama-chromatogram aphelele ewayini ngalinye, angafaka amaphuzu afika ku-30.000, futhi afingqe ichromatogram ngayinye kumadidiyela amabili u-X kanye no-Y, le nqubo ibizwa ngokuthi ukuncishiswa kobukhulu.

Ngokubeka izixhumanisi ezintsha kugrafu, abacwaningi bakwazi ukubona 'amafu' ayisikhombisa amaphuzu futhi bathola ukuthi ngayinye yalawa iqoqe ndawonye ama-vintage efa elifanayo ngokusekelwe ekufananeni kwawo kwamakhemikhali. Ngale ndlela abacwaningi bakwazi ukukhombisa ukuthi inkampani ngayinye inesiginesha yayo yamakhemikhali.

Phakathi nokuhlaziya kwabo, abacwaningi bathola lokho ubunikazi bamakhemikhali alawa mawayini bebungekho defiibangelwa ukuhlangana kwama-molecule athile, kodwa kusukela ku-spectrum yamakhemikhali ebanzi. "Imiphumela yethu ikhombisa ukuthi kungenzeka ukuhlonza imvelaphi yendawo yewayini ngokunemba okungu-100%, ngokusebenzisa amasu okunciphisa ubukhulu kuma-chromatogram egesi - kudwetshelwe uPouget, ophinde wahola ucwaningo - ucwaningo lunikeza ulwazi olusha ngezingxenye zobunikazi kanye Izinzwa zewayini. Kuphinde kuphendle indlela yokuthuthukiswa kwamathuluzi okusekela inqubo yokwenza izinqumo, njengokugcina ubunikazi kanye nokuvezwa kwendawo kanye, nokulwa ngokuphumelelayo nomgunyathi."
