\u2026\u017ee ste ich prevarili.<\/p>\n\n\n\n
Nebojte sa, tak\u00e9to vajce nie je ani pokazen\u00e9, ani jedovat\u00e9, ani neobsahuje \u017eiadne \u017eiviny. Je to \u010dist\u00e1 ch\u00e9mia, ktor\u00fa by sme v kuchynskom laborat\u00f3riu op\u00edsali takto:<\/p>\n\n\n\n
\u010co sa vlastne stalo?<\/p>\n\n\n\n
Sivozelen\u00fd a\u017e \u010dierny kr\u00fa\u017eok na povrchu \u017e\u013atka je sp\u00f4soben\u00fd reakciou medzi \u017eelezom v \u017e\u013atku a s\u00edrou v bielku.<\/p>\n\n\n\n
Ak var\u00edte vajce dlh\u0161ie ako 10 \u2013 12 min\u00fat, teplo uvo\u013e\u0148uje vod\u00edk a s\u00edru v bielku, \u010d\u00edm vznik\u00e1 plyn (sulf\u00e1n).<\/p>\n\n\n\n
Tento plyn reaguje so \u017eelezom na okraji \u017e\u013atka za vzniku sulfidu \u017eeleznat\u00e9ho (FeS).<\/p>\n\n\n\n
V\u00fdsledkom je tento vizu\u00e1lne neatrakt\u00edvny, ale zdrav\u00fd zelen\u00fd kr\u00fa\u017eok. Ako sa tomu m\u00f4\u017eete nabud\u00face vyhn\u00fa\u0165?<\/p>\n\n\n\n
Pre kr\u00e1sny, s\u00fdto\u017elt\u00fd \u017e\u013atok bez nevzh\u013eadn\u00e9ho \u201emaskovacieho\u201c efektu vysk\u00fa\u0161ajte nasledovn\u00e9:<\/p>\n\n\n\n
D\u00e1vajte pozor na \u010das: Pre vajcia natvrdo sta\u010d\u00ed 9 a\u017e 10 min\u00fat od zovretia vody.<\/p>\n\n\n\n
\u0160okov\u00e1 terapia: Vajcia ihne\u010f po uvaren\u00ed ochla\u010fte v \u013eadovej vode. T\u00fdm sa zastav\u00ed proces varenia a zabr\u00e1ni sa \u010fal\u0161iemu uvo\u013e\u0148ovaniu plynov, ktor\u00e9 sp\u00f4sobuj\u00fa zmenu farby.<\/p>\n\n\n\n
Nepou\u017e\u00edvajte pr\u00edli\u0161 star\u00e9 vajcia: \u010c\u00edm je vajce star\u0161ie, t\u00fdm vy\u0161\u0161ia je jeho hodnota pH, \u010do ur\u00fdch\u013euje chemick\u00fa reakciu.<\/p>\n\n\n\n
Mal\u00fd tip: Ak je \u017e\u013atok po rozrezan\u00ed nielen zelen\u00fd, ale aj silne zap\u00e1cha (ako zhnit\u00e9 vajcia), alebo ak je bielok ru\u017eov\u00fd, pravdepodobne by ste mali vajce vyhodi\u0165. Typick\u00fd \u201eprepe\u010den\u00fd\u201c okraj je v\u0161ak len kozmetick\u00e1 chyba.<\/p>\n\n\n\n
Chcete vedie\u0165, ako zisti\u0165, \u010di je vajce \u010derstv\u00e9, predt\u00fdm ako ho rozbijete, pomocou jednoduch\u00e9ho vodn\u00e9ho testu?<\/p>\n","protected":false},"excerpt":{"rendered":"
