Makarna, patates, ekmek…
\nOregon \u00dcniversitesi G\u0131da Bilimi ve Teknolojileri B\u00f6l\u00fcm\u00fc’nden Do\u00e7. Dr. Juyun Lim, yapt\u0131klar\u0131 ara\u015ft\u0131rmada insan\u0131n tat alma duyusunun makarna, pasta, patates ve ekmek gibi g\u0131da \u00fcr\u00fcnlerindeki karbonhidratlar\u0131 ay\u0131rt edebildi\u011fini ortaya \u00e7\u0131kard\u0131klar\u0131n\u0131 s\u00f6yledi.<\/p>\n
Lim, “Her k\u00fclt\u00fcr\u00fcn bir ana karbonhidrat kayna\u011f\u0131 var. Ara\u015ft\u0131rma s\u0131ras\u0131nda g\u00f6n\u00fcll\u00fclere t\u00fck\u00fcr\u00fck enzimlerini ve tatl\u0131 al\u0131c\u0131lar\u0131n\u0131 bloke eden bir kar\u0131\u015f\u0131m verdik. Daha sonra g\u00f6n\u00fcll\u00fclere farkl\u0131 seviyelerde ayr\u0131\u015ft\u0131rd\u0131\u011f\u0131m\u0131z karbonhidrat\u0131 s\u0131v\u0131 olarak verdik. Ara\u015ft\u0131rmaya kat\u0131lanlar, denedikleri tad\u0131 ‘ni\u015fastal\u0131’ olarak tan\u0131mlad\u0131. Asya k\u00f6kenli g\u00f6n\u00fcll\u00fcler s\u00f6z konusu tad\u0131 pirince benzetirken beyaz \u0131rktan gelenler tad\u0131 tan\u0131mlamak i\u00e7in ekme\u011fi kulland\u0131.” dedi.<\/p>\n
Hen\u00fcz dil \u00fczerinde sadece “ni\u015fastay\u0131” ay\u0131rt eden al\u0131c\u0131lar\u0131 bulamad\u0131klar\u0131n\u0131 belirten Lim, ara\u015ft\u0131rmalar\u0131n\u0131n devam etti\u011fini s\u00f6zlerine ekledi.<\/p>\n
\u015eimdiye kadar insan t\u00fck\u00fcr\u00fc\u011f\u00fcndeki enzimlerin ni\u015fasta molek\u00fcllerini basit \u015fekere ay\u0131rabildi\u011fi ve insan\u0131n sadece karbonhidrattaki \u015fekeri tadabildi\u011fi san\u0131l\u0131yordu.<\/p>\n
Be\u015finci tat: Umami
\nTatl\u0131, tuzlu, ac\u0131 ve ek\u015fi temel tatlar\u0131na yedi y\u0131l \u00f6nce umami de eklenmi\u015fti. Dildeki L glutamat al\u0131c\u0131lar\u0131yla alg\u0131lanan be\u015finci temel tada, Japoncada “lezzetli” anlam\u0131na gelen “umai” ve “tat” anlam\u0131na gelen “mi” s\u00f6zc\u00fckleri birle\u015ftirilerek t\u00fcretilen umami ad\u0131 verilmi\u015fti.<\/p>\n
