V tomto preh\u013eade sa \u010disto fakticky pozrieme na to, \u010do k\u00e1va obsahuje (kofe\u00edn ako pr\u00edrodn\u00e1 zlo\u017eka, polyfenoly, kyseliny chlorogenov\u00e9, melanoid\u00edny vznikaj\u00face pri pra\u017een\u00ed), \u010d\u00edm sa l\u00ed\u0161i k\u00e1va bez kofe\u00ednu, ko\u013eko kofe\u00ednu sa zvy\u010dajne nach\u00e1dza v \u0161\u00e1lke a ako si k\u00e1vu \u010do najlep\u0161ie pripravi\u0165. Nejde o zdravotn\u00e9 poradenstvo ani o tvrdenia o \u00fa\u010dinkoch k\u00e1vy.<\/p>\n<\/div>\n

K\u00e1va je jedn\u00fdm z najroz\u0161\u00edrenej\u0161\u00edch a z\u00e1rove\u0148 chemicky najzauj\u00edmavej\u0161\u00edch n\u00e1pojov na svete.

Za chu\u0165ou, ar\u00f3mou aj farbou n\u00e1poja stoja stovky prirodzene obsiahnut\u00fdch l\u00e1tok. Medzi naj\u010dastej\u0161ie spom\u00ednan\u00e9 patria:<\/p>\n

    \n
  • Kofe\u00edn:<\/strong> prirodzen\u00e1 zlo\u017eka k\u00e1vov\u00fdch z\u0155n. Jeho obsah z\u00e1vis\u00ed od odrody (Arabica ho zvy\u010dajne obsahuje menej ako Robusta), d\u00e1vky a sp\u00f4sobu pr\u00edpravy. Orient\u00e1ciou je, \u017ee v \u0161\u00e1lke prekvapk\u00e1vanej k\u00e1vy je pribli\u017ene 80\u2013120 mg kofe\u00ednu, v espresse pribli\u017ene 60\u201380 mg.<\/li>\n
  • Polyfenoly a chlorogenov\u00e9 kyseliny:<\/strong> skupina l\u00e1tok, ktor\u00e9 sa prirodzene nach\u00e1dzaj\u00fa v zelen\u00fdch aj pra\u017een\u00fdch zrn\u00e1ch. Ich mno\u017estvo sa men\u00ed v z\u00e1vislosti od stup\u0148a pra\u017eenia \u2013 tmav\u0161ie pra\u017eenie ich zvy\u010dajne \u010diasto\u010dne odstra\u0148uje.<\/li>\n

    Mnoh\u00e9 z t\u00fdchto l\u00e1tok zost\u00e1vaj\u00fa v zrn\u00e1ch aj po odstr\u00e1nen\u00ed kofe\u00ednu, tak\u017ee aj k\u00e1va bez kofe\u00ednu (dekofe\u00ednovan\u00e1) si zachov\u00e1va podobn\u00e9 chemick\u00e9 zlo\u017eenie aj chu\u0165ov\u00e9 vlastnosti ako klasick\u00e1 k\u00e1va.<\/p>\n

    K\u00e1va bez kofe\u00ednu a obsah kofe\u00ednu<\/h2>\n

    Kofe\u00edn je prirodzen\u00e1 zlo\u017eka k\u00e1vy, ktor\u00fa mo\u017eno pri dekafein\u00e1cii z ve\u013ekej \u010dasti odstr\u00e1ni\u0165. Dekofe\u00ednovan\u00e1 k\u00e1va nie je \u00faplne \u201ebez kofe\u00ednu\u201c \u2013 obsahuje len stopov\u00e9 mno\u017estvo.

Je to praktick\u00e1 vo\u013eba, ak si chcete ve\u010der dopria\u0165 \u0161\u00e1lku k\u00e1vy alebo ak chcete obmedzi\u0165 mno\u017estvo kofe\u00ednu vo svojom dennom re\u017eime.<\/p>\n

    Kofe\u00edn sa zo z\u0155n odstra\u0148uje pomocou viacer\u00fdch technologick\u00fdch postupov. Medzi \u010dasto spom\u00ednan\u00e9 patr\u00ed met\u00f3da Swiss Water<\/strong>, pri ktorej sa pracuje iba s vodou a akt\u00edvnym uhl\u00edm, bez pou\u017eitia rozp\u00fa\u0161\u0165adiel. Jednotliv\u00e9 met\u00f3dy sa l\u00ed\u0161ia t\u00fdm, do akej miery sa pri nich dar\u00ed zachova\u0165 p\u00f4vodn\u00fa chu\u0165 z\u0155n.<\/p>\n
