Krvav\u00e9 \u0161kvrny vo vajciach: \u010co znamenaj\u00fa a \u010di s\u00fa bezpe\u010dn\u00e9 na konzum\u00e1ciu<\/p>\n\n\n\n
U\u017e ste niekedy rozbili vajce a objavili vo vn\u00fatri mal\u00fa \u010derven\u00fa \u0161kvrnu? Ak\u00e1 bola va\u0161a prv\u00e1 reakcia? Vyhodili ste vajce alebo ste \u0161kvrnu jednoducho ignorovali a pokra\u010dovali vo varen\u00ed? Mnoh\u00ed spotrebitelia si nie s\u00fa ist\u00ed, ke\u010f objavia tieto takzvan\u00e9 krvav\u00e9 \u0161kvrny. V tomto \u010dl\u00e1nku vysvet\u013eujeme, ako tieto \u0161kvrny vznikaj\u00fa, \u010do nazna\u010duj\u00fa o kvalite vajca a \u010di je ich konzum\u00e1cia bezpe\u010dn\u00e1.<\/p>\n\n\n\n
S\u00fa vajcia s krvav\u00fdmi \u0161kvrnami bezpe\u010dn\u00e9 na konzum\u00e1ciu?<\/p>\n\n\n\n
Stru\u010dn\u00e1 odpove\u010f znie: \u00c1no, ur\u010dite \u2013 za predpokladu, \u017ee vajce je d\u00f4kladne uvaren\u00e9. Tieto \u010derven\u00e9 \u0161kvrny s\u00fa \u00faplne ne\u0161kodn\u00e9 a nesp\u00f4sobuj\u00fa ochorenie. Vajce m\u00f4\u017eete pou\u017ei\u0165 ako obvykle. Ak v\u00e1m poh\u013ead prek\u00e1\u017ea, \u0161kvrnu mo\u017eno \u013eahko odstr\u00e1ni\u0165 \u0161pi\u010dkou no\u017ea alebo malou ly\u017ei\u010dkou predt\u00fdm, ako za\u010dnete s pr\u00edpravou. Je to len kozmetick\u00e1 chyba, nie hygienick\u00fd probl\u00e9m.<\/p>\n\n\n\n
\u0160kvrny od m\u00e4sa a zmenen\u00e1 farba bielka: Kedy je potrebn\u00e1 opatrnos\u0165<\/p>\n\n\n\n
Okrem krvav\u00fdch \u0161kv\u0155n sa na bielku m\u00f4\u017eu objavi\u0165 aj hned\u00e9 \u201e\u0161kvrny od m\u00e4sa\u201c. Ide o drobn\u00e9 k\u00fasky tkaniva, ktor\u00e9 vajce nabralo na ceste cez vajcovod slepice. Tieto s\u00fa tie\u017e ne\u0161kodn\u00e9. Situ\u00e1cia je v\u0161ak in\u00e1, ak m\u00e1 bielok \u010derven\u00fd, ru\u017eov\u00fd alebo zelenkast\u00fd odtie\u0148. V takom pr\u00edpade by ste mali vajce okam\u017eite zlikvidova\u0165. Tak\u00e9to zafarbenie zvy\u010dajne nazna\u010duje nebezpe\u010dn\u00fd rast bakt\u00e9ri\u00ed, ktor\u00fd m\u00f4\u017ee sp\u00f4sobi\u0165 v\u00e1\u017enu otravu jedlom.<\/p>\n\n\n\n

Ako \u010dasto sa tieto \u0161kvrny vyskytuj\u00fa?<\/p>\n\n\n\n
V skuto\u010dnosti menej ako 1 % v\u0161etk\u00fdch vajec obsahuje tak\u00e9to krvav\u00e9 \u0161kvrny. Ak si k\u00fapite vajcia v supermarkete, takmer sa s nimi nestretnete. Je to kv\u00f4li priemyseln\u00e9mu triedeniu, zn\u00e1memu ako \u201epresvietenie\u201c. Vajcia sa kontroluj\u00fa pod siln\u00fdm sveteln\u00fdm zdrojom; vajcia s vidite\u013en\u00fdmi inkl\u00faziami sa vyra\u010fuj\u00fa. Pravdepodobnos\u0165 je v\u0161ak vy\u0161\u0161ia pri \u010derstv\u00fdch vajciach priamo z farmy alebo od vlastn\u00fdch sliepok, preto\u017ee sa \u010dasto nevykon\u00e1va technicky vyspel\u00e9 triedenie. Okrem toho s\u00fa hned\u00e9 vajcia n\u00e1chylnej\u0161ie, preto\u017ee \u0161kvrny sa kv\u00f4li tmav\u0161ej \u0161krupine \u0165a\u017e\u0161ie odha\u013euj\u00fa.<\/p>\n\n\n\n
Pre\u010do sa v\u00f4bec objavuj\u00fa krvav\u00e9 \u0161kvrny?<\/p>\n\n\n\n
Be\u017en\u00fd m\u00fdtus tvrd\u00ed, \u017ee krvav\u00e1 \u0161kvrna znamen\u00e1, \u017ee vaj\u00ed\u010dko je oplodnen\u00e9. To je jednoducho lo\u017e. Krvav\u00e9 \u0161kvrny s\u00fa sp\u00f4soben\u00e9 prasknut\u00edm drobn\u00fdch krvn\u00fdch ciev vo vaje\u010dn\u00edkoch alebo vajcovode sliepky po\u010das tvorby vaj\u00ed\u010dka. Ak je \u0161kvrna v \u017e\u013atku, stalo sa to vo vaje\u010dn\u00edku. Ak je \u0161kvrna v bielku, krv\u00e1canie sa stalo nesk\u00f4r vo vajcovode. Je to \u00faplne prirodzen\u00fd, biologick\u00fd proces a nie znak oplodnenia alebo nedostatku \u010derstvosti.<\/p>\n\n\n\n
Tipy na spr\u00e1vne skladovanie a pr\u00edpravu<\/p>\n\n\n\n
Bez oh\u013eadu na ak\u00e9ko\u013evek vizu\u00e1lne nedostatky by sa vajcia mali v\u017edy spr\u00e1vne skladova\u0165. Zak\u00fapen\u00e9 vajcia by sa mali skladova\u0165 v chladni\u010dke, zatia\u013e \u010do ve\u013emi \u010derstv\u00e9 vajcia z farmy sa m\u00f4\u017eu skladova\u0165 na chladnom a tmavom mieste pri izbovej teplote. Nikdy nepou\u017e\u00edvajte vajcia s prasklinami v \u0161krupine, preto\u017ee to vytv\u00e1ra pr\u00edle\u017eitos\u0165 pre salmonelu. Pred manipul\u00e1ciou so surov\u00fdmi vajcami a po nej si d\u00f4kladne umyte ruky. Vajce sa pova\u017euje za bezpe\u010dn\u00e9, ke\u010f s\u00fa \u017e\u013atok aj bielok pevne stuhnut\u00e9.<\/p>\n\n\n\n
Pri preprave vajec, napr\u00edklad po\u010das pikniku, sa uistite, \u017ee s\u00fa skladovan\u00e9 v chladni\u010dke a nie s\u00fa vystaven\u00e9 priamemu slne\u010dn\u00e9mu \u017eiareniu. Ak po konzum\u00e1cii vaje\u010dn\u00fdch jed\u00e1l poc\u00edtite pr\u00edznaky, ako je vracanie, hna\u010dka alebo hor\u00fa\u010dka, okam\u017eite sa pora\u010fte s lek\u00e1rom. Dodr\u017eujte pitn\u00fd re\u017eim a odpo\u010d\u00edvajte. V\u00e4\u010d\u0161ine riz\u00edk sa v\u0161ak d\u00e1 \u00fa\u010dinne vyhn\u00fa\u0165 jednoduchou kuchynskou hygienou a d\u00f4kladn\u00fdm tepeln\u00fdm spracovan\u00edm.<\/p>\n\n\n\n
