Grilovac\u00ed sez\u00f3na je v pln\u00e9m proudu. Spot\u0159ebitelsk\u00e1 organizace dTest proto nechala otestovat dvan\u00e1ct vzork\u016f mlet\u00e9ho masa \u2013 osm \u010dist\u011b hov\u011bz\u00edch a \u010dty\u0159i m\u00edchan\u00e9. Na prvn\u00ed pohled toto\u017en\u00e9 v\u00fdrobky ofici\u00e1ln\u011b spadaj\u00ed do dvou z\u00e1kladn\u00edch skupin. Prvn\u00ed z nich p\u0159edstavovalo mlet\u00e9 maso. U druh\u00e9 skupiny \u0161lo o v\u00fdrobky z mlet\u00e9ho masa \u010di m\u011bln\u011bn\u00e9 maso a spole\u010dn\u00fdm znakem bylo za\u0159azen\u00ed mezi polotovary. Dobrou zpr\u00e1vou je, \u017ee u obou skupin mohla laborato\u0159 konstatovat mikrobiologickou nez\u00e1vadnost.<\/h6>\n

\"\"V celkov\u00e9m hodnocen\u00ed byl rozhoduj\u00edc\u00ed v\u00fdsledek anal\u00fdzy obsahu masa. S mlet\u00fdm masem je to jednoduch\u00e9, proto\u017ee obsahuje pouze maso bez dal\u0161\u00edch p\u0159\u00edsad. Umlet\u00e9 maso prod\u00e1van\u00e9 coby polotovar u\u017e m\u016f\u017ee obsahovat i n\u011bco nav\u00edc, v\u00fdrobce v\u0161ak mus\u00ed dodr\u017eet ve\u0161ker\u00e9 deklarace na obalech. Polotovary se proto testuj\u00ed podobn\u011b jako masn\u00e9 v\u00fdrobky a sleduje se u nich zejm\u00e9na obsah masa, kter\u00fd mus\u00ed souhlasit s \u00fadajem na etiket\u011b.<\/p>\n

Obsah masa laborato\u0159 ov\u011b\u0159ovala nep\u0159\u00edmou metodou, kter\u00e1 je zat\u00ed\u017eena a\u017e desetiprocentn\u00ed nejistotou, proto se s n\u00ed lze dobrat i k v\u00edce ne\u017e 100% pod\u00edl\u016fm masa. Nejni\u017e\u0161\u00ed pod\u00edl masa laborato\u0159 zaznamenala u \u010dist\u011b hov\u011bz\u00edho polotovaru Billa\/Voc\u00edlka Hov\u011bz\u00ed maso m\u011bln\u011bn\u00e9 speci\u00e1l.<\/p>\n

Nam\u011b\u0159en\u00e9 hodnoty obsahu masa pak dTest porovnal s \u00fadaji na etiket\u00e1ch. \u201eV\u011bt\u0161ina v\u00fdrobk\u016f touto zkou\u0161kou pro\u0161la bez z\u00e1sadn\u00edch z\u00e1vad, jedin\u00fd v\u00e1\u017en\u00fd probl\u00e9m jsme odhalili u v\u00fd\u0161e zm\u00edn\u011bn\u00e9ho polotovaru Billa\/Voc\u00edlka. Podle etikety m\u011bl obsahovat 95\u2009% hov\u011bz\u00edho masa, \u010demu\u017e se v\u0161ak nalezen\u00fdch 84\u2009% nep\u0159ibl\u00ed\u017eilo ani po p\u0159ipo\u010dten\u00ed nejistoty m\u011b\u0159en\u00ed. Za klam\u00e1n\u00ed z\u00e1kazn\u00edk\u016f si tak hov\u011bz\u00ed polotovar Billa\/Voc\u00edlka odnesl nedostate\u010dnou zn\u00e1mku,”<\/em> uv\u00e1d\u00ed \u0161\u00e9fredaktorka \u010dasopisu dTest Hana Hoffmannov\u00e1.<\/p>\n

K dal\u0161\u00edm d\u016fle\u017eit\u00fdm parametr\u016fm pat\u0159il procentu\u00e1ln\u00ed pod\u00edl kolagenu na celkov\u00e9m obsahu b\u00edlkovin. Toto \u010d\u00edslo vyjad\u0159uje mno\u017estv\u00ed pojivov\u00e9 tk\u00e1n\u011b \u2013 nap\u0159\u00edklad \u0161lach, k\u016f\u017e\u00ed \u010di chrupavek \u2013 ve v\u00fdrobku. \u010c\u00edm ni\u017e\u0161\u00ed pom\u011br kolagenu, t\u00edm dokonaleji o\u010di\u0161t\u011bn\u00e9 maso v\u00fdrobce pou\u017eil. Z\u00e1rove\u0148 jde o d\u016fle\u017eit\u00fd parametr jakosti mlet\u00e9ho masa. Zji\u0161t\u011bn\u00fd pom\u011br kolagenu v b\u00edlkovin\u00e1ch se u \u010dist\u011b hov\u011bz\u00edho masa pohyboval od 6,1 % do 16,2 %, p\u0159i\u010dem\u017e vzorek s druhou uvedenou hodnotou p\u0159es\u00e1hl z\u00e1konn\u00e9 po\u017eadavky na kvalitu.<\/p>\n

Druhou z\u00e1sadn\u00ed vlastnost\u00ed mlet\u00e9ho masa je tu\u010dnost. Podle na\u0159\u00edzen\u00ed Evropsk\u00e9 unie by u hov\u011bz\u00edho nem\u011bla p\u0159ekro\u010dit 20\u2009%, sm\u011bs hov\u011bz\u00edho s vep\u0159ov\u00fdm pak m\u016f\u017ee obsahovat nejv\u00fd\u0161e 30\u2009% tuku. Informace o tu\u010dnosti tak\u00e9 pat\u0159\u00ed mezi povinn\u00e9 \u00fadaje na obalu.<\/p>\n

\u201eSamotn\u00e9 hov\u011bz\u00ed je p\u0159irozen\u011b libov\u011bj\u0161\u00ed. V pr\u016fm\u011bru se pod\u00edl tuku v testovan\u00fdch produktech pohyboval okolo 10,5\u2009%. Bohu\u017eel jsme u mlet\u00e9ho hov\u011bz\u00edho narazili na dva probl\u00e9my s p\u0159ekro\u010den\u00edm hodnot deklarovan\u00fdch na obale. V\u00fdrobky Tesco Mlet\u00e9 maso hov\u011bz\u00ed a Albertovo kvalitn\u00ed Hov\u011bz\u00ed v\u00fdrobek z mlet\u00e9ho masa obsahovaly shodn\u011b 11,8\u2009% tuku, p\u0159esto\u017ee deklarovaly 9,4\u2009%, respektive 8,7\u2009%,”<\/em> \u0159\u00edk\u00e1 Hana Hoffmannov\u00e1.<\/p>\n

V mixovan\u00e9m mase m\u016f\u017eete po\u010d\u00edtat s asi 21\u2009% tuku, p\u0159i\u010dem\u017e jeho obsah v testovan\u00fdch vzorc\u00edch kol\u00edsal od 17,1\u2009% do 25,5\u2009%.<\/p>\n

U mlet\u00e9ho masa je kl\u00ed\u010dov\u00e1 jeho mikrobiologick\u00e1 \u010distota. V posledn\u00ed den trvanlivosti se laborato\u0159 zaj\u00edmala o (ne)p\u0159\u00edtomnost nebezpe\u010dn\u00fdch bakteri\u00ed listeri\u00ed, salmonel, celkov\u00e9 po\u010dty mikrob\u016f a bakteri\u00ed Escherichia coli. Listerie ani salmonely se v \u017e\u00e1dn\u00e9m ze vzork\u016f nena\u0161ly v\u016fbec. Kontrolovaly se i celkov\u00e9 po\u010dty mikrob\u016f a escherichi\u00ed. Ani v jejich p\u0159\u00edpad\u011b nebyl d\u016fvod ke znepokojen\u00ed.<\/p>\n

P\u0159i kontrole etiket si dTest, krom\u011b p\u0159esnosti deklarace obsahu tuku a masa, v\u0161\u00edmal i uveden\u00fdch ingredienc\u00ed. U mlet\u00e9ho masa \u017e\u00e1dn\u00e9 slo\u017een\u00ed obvykle nenajdete, v\u00fdjimkou jsou pouze mixovan\u00e9 v\u00fdrobky, kde se uv\u00e1d\u00ed pod\u00edl jednotliv\u00fdch druh\u016f mas. U polotvar\u016f v\u0161ak m\u016f\u017eeme o\u010dek\u00e1vat celou \u0161k\u00e1lu p\u0159\u00edsad.<\/p>\n
