Annotation Teoretická část diplomové práce se zabývá složením a výrobou čaje s bližším zaměřením na čínské a japonské čaje matcha a na obsah jejich bioaktivních látek. Dále jsou zde zahrnuty informace o pitné vodě a přírodních minerálních vodách. Praktická část cílí na vliv, který má koncentrace minerálních prvků přítomných ve vodě na obsah polyfenolů, vitaminu C a na barvu infuze čaje. V těchto aspektech a z hlediska organoleptických vlastností mezi sebou byla porovnána čínská a japonská matcha.
Annotation in English The theoretical part of the thesis deals with the composition and production of tea with a closer focus on Chinese and Japanese matcha teas and the content of their bioactive substances. It also includes information on drinking water and natural mineral waters. The practical part focuses on the effect that the concentration of mineral elements present in water has on the content of polyphenols, vitamin C and the color of tea infusion. In these aspects and in terms of organoleptic properties, Chinese and Japanese matcha were compared with each other.
Keywords matcha, polyfenoly, vitamin C, mineralizace vod
