Co se stane, kdy\u017e se dovnit\u0159 dostane vzduch nebo vlhkost?<\/h3>\n\n\n\n

Hlavn\u00edm nep\u0159\u00edtelem v mraz\u00e1ku je sp\u00e1len\u00ed v mraz\u00e1ku<\/strong>. This isn\u2019t a \u201cburn\u201d from heat; it\u2019s a \u201cburn\u201d from dehydration. The air inside your freezer is very, very dry. If your container has a weak seal (like a loose lid, thin plastic wrap, or a zip\u2011top bag that doesn’t opravdu<\/em> zip), such\u00fd vzduch vytahuje vlhkost p\u0159\u00edmo z potravin.<\/p>\n\n\n\n

To zp\u016fsobuje dva velk\u00e9 probl\u00e9my.  <\/p>\n\n\n\n

    \n
  1. Na mase nebo zelenin\u011b se objev\u00ed tvrd\u00e9, \u0161ed\u00e9, ko\u017eovit\u00e9 skvrny.\u00a0\u00a0<\/li>\n\n\n\n
  2. Vzniknou velk\u00e9 ledov\u00e9 krystalky.<\/li>\n<\/ol>\n\n\n\n

    Velk\u00e9 krystalky ledu vznikaj\u00ed, kdy\u017e se z potravin uvol\u0148uje vlhkost, kter\u00e1 pak znovu zmrzne na povrchu potravin nebo na vnit\u0159n\u00ed stran\u011b v\u00edka. Tyto krystalky jsou neklamn\u00fdm znamen\u00edm, \u017ee t\u011bsn\u011bn\u00ed n\u00e1doby selhalo. Dokonce i mal\u00e1, mikroskopick\u00e1 mezera<\/a> sta\u010d\u00ed, aby se dovnit\u0159 dostal vzduch a zah\u00e1jil proces. 2<\/a>{#ref-2}<\/sup><\/p>\n\n\n\n

    Jak \u0161patn\u00e1 volba n\u00e1doby ovliv\u0148uje chu\u0165, texturu a bezpe\u010dnost?<\/h3>\n\n\n\n

    Kdy\u017e se vytvo\u0159\u00ed velk\u00e9 ledov\u00e9 krystalky, jsou jako mal\u00e9 no\u017ee. Proraz\u00ed a roztrhnou bun\u011b\u010dn\u00e9 st\u011bny potravin. Kdy\u017e potraviny rozmraz\u00edte, ve\u0161ker\u00e1 vlhkost (a chu\u0165) unikne ven. Proto je v\u00e1\u0161 kdysi \u0161\u0165avnat\u00fd steak tvrd\u00fd a such\u00fd a zmrzl\u00e9 bobule se zm\u011bn\u00ed na vodnatou ka\u0161i. Textura je \u00fapln\u011b zni\u010den\u00e1.<\/p>\n\n\n\n

    Chu\u0165 ovliv\u0148uje tak\u00e9 p\u0159enos z\u00e1pachu<\/strong>. Plast, zejm\u00e9na star\u0161\u00ed nebo levn\u011bj\u0161\u00ed plast, je por\u00e9zn\u00ed materi\u00e1l. Absorbuje pach chilli, kter\u00e9 jste skladovali minul\u00fd m\u011bs\u00edc. Kdy\u017e zmraz\u00edte nov\u00e9 potraviny, nap\u0159\u00edklad ryby, m\u016f\u017ee se tento pach chilli p\u0159en\u00e9st na<\/em> ryby. Na druhou stranu sklo je nepor\u00e9zn\u00ed<\/strong>. Je to chemicky inertn\u00ed<\/a>. Nikdy neabsorbuje pachy ani skvrny. 3<\/a>{#ref-3}<\/sup><\/p>\n\n\n\n

    D\u016fle\u017eit\u00fdm faktorem je tak\u00e9 bezpe\u010dnost. Zat\u00edmco zmrazen\u00ed zabra\u0148uje bakteri\u00edm p\u011bstov\u00e1n\u00ed<\/em>, it doesn’t kill it. A container that isn’t airtight or is made of the wrong material might crack in the cold, exposing your food. Worse, if a plastic container isn’t certified food\u2011safe, it could leach chemicals (like BPA) into your food.<\/p>\n\n\n\n

    Jak sladit velikost n\u00e1doby s mrazic\u00edmi porcemi<\/h3>\n\n\n\n

    This is a technical detail that many people miss, but it’s very important. You need to leave n\u011bkter\u00e9<\/em> prostoru, ale ne p\u0159\u00edli\u0161 mnoho.<\/p>\n\n\n\n

    Tekutiny, jako jsou pol\u00e9vky, du\u0161en\u00e9 maso a v\u00fdvary, se mohou roz\u0161\u00ed\u0159it<\/strong> kdy\u017e zamrznou. Pokud sklen\u011bnou n\u00e1dobu napln\u00edte a\u017e po sam\u00fd vrchol a uzav\u0159ete ji, sklo bude<\/em> praskliny. Vid\u011bl jsem to. Mus\u00edte leave “headspace”<\/a>-p\u0159ibli\u017en\u011b jeden palec (2-3 cm) v horn\u00ed \u010d\u00e1sti, abyste umo\u017enili toto roz\u0161\u00ed\u0159en\u00ed. 4<\/a>{#ref-4}<\/sup><\/p>\n\n\n\n

    U netekut\u00fdch potravin (nap\u0159. tuh\u00e9ho masa nebo zbytk\u016f pokrm\u016f), p\u0159\u00edli\u0161 mnoho<\/em> prostor je \u0161patn\u00fd. V\u0161echen ten prostor nav\u00edc je jen vzduchov\u00e1 kapsa. V\u00edce vzduchu znamen\u00e1 v\u011bt\u0161\u00ed mo\u017enost sp\u00e1len\u00ed mraz\u00e1ku.<\/p>\n\n\n\n

    C\u00edlem je n\u00e1dobu naplnit a ponechat pouze nezbytn\u00fd prostor pro expanzi (u kapalin) nebo jen malou mezeru (u pevn\u00fdch l\u00e1tek), aby se minimalizoval kontakt se vzduchem.

    Think about storing tomato soup or a red curry. In a plastic container, you are left with a permanent orange stain and a faint curry smell you can’t wash out. Glass, however, is like a clean slate. It washes perfectly clean every single time, protecting the taste of your next meal.<\/p>\n\n\n\n

    For liquids, glass provides a rigid, reliable structure. Freezer bags can puncture or flop over when thawing, creating a mess. Glass containers stack neatly and provide a solid, leak\u2011proof seal. You don’t have to worry about a \u201cchili avalanche\u201d in your freezer.<\/p>\n\n\n\n

    Proto\u017ee sklo nen\u00ed por\u00e9zn\u00ed, samo o sob\u011b p\u0159edstavuje dokonalou bari\u00e9ru proti vzduchu a vlhkosti. Sklen\u011bn\u00e1 st\u011bna je jako pevnost.

      I believe in using the right tool for the right job. While I am partial to glass for its health and environmental benefits (Safer, Healthier, Greener!), I know that plastic and vacuum systems have their place. Let’s compare them fairly.<\/p>\n\n\n\n

      Stoj\u00ed plasty vhodn\u00e9 pro ka\u017edodenn\u00ed pou\u017eit\u00ed v mrazni\u010dce za to?<\/h3>\n\n\n\n

      Plastov\u00e9 n\u00e1doby jsou obl\u00edben\u00e9 z ur\u010dit\u00e9ho d\u016fvodu. Jsou lehk\u00e9, levn\u00e9 a nerozbij\u00ed se, kdy\u017e je upust\u00edte na podlahu.<\/p>\n\n\n\n

      Pokud se rozhodnete pro plast, m\u016f\u017eete mus\u00ed<\/em> ujist\u011bte se, \u017ee je ozna\u010den n\u00e1pisem \u201cBezpe\u010dn\u00e9 v mrazni\u010dce\u201d a \u201cBez BPA\u201d. Nejvhodn\u011bj\u0161\u00edm plastem je polypropylen (ozna\u010den\u00fd recykla\u010dn\u00edm symbolem #5).<\/p>\n\n\n\n

      Nev\u00fdhody jsou v\u0161ak zna\u010dn\u00e9. Jak jsem ji\u017e \u0159ekl, plast je por\u00e9zn\u00ed<\/strong>. Je to bude<\/em> pohlcuj\u00ed skvrny a pachy. \u010casem se tak\u00e9 rozkl\u00e1d\u00e1. Chlad ho \u010din\u00ed k\u0159ehk\u00fdm a vysok\u00e9 teploty v my\u010dce n\u00e1dob\u00ed nebo mikrovlnn\u00e9 troub\u011b zp\u016fsobuj\u00ed degradaci a deformaci materi\u00e1lu.<\/p>\n\n\n\n

      Tato degradace je probl\u00e9m. M\u016f\u017ee v\u00e9st ke vzniku mikro\u0161kr\u00e1banc\u016f, ve kter\u00fdch se skr\u00fdvaj\u00ed bakterie.

Pro kr\u00e1tkodob\u00e9 zmrazen\u00ed (t\u00fdden nebo dva) jsou v po\u0159\u00e1dku. Pro dlouhodob\u00e9 skladov\u00e1n\u00ed drah\u00fdch potravin se jim vyh\u00fdb\u00e1m.<\/p>\n\n\n\n

      Opravdu vakuov\u011b uzav\u0159en\u00e9 s\u00e1\u010dky zabra\u0148uj\u00ed sp\u00e1len\u00ed v mraz\u00e1ku?<\/h3>\n\n\n\n

      Ano. A vakuov\u00e1 sv\u00e1\u0159e\u010dka<\/a> je pravd\u011bpodobn\u011b absolutn\u011b nejlep\u0161\u00ed<\/em> zp\u016fsob, jak zabr\u00e1nit sp\u00e1len\u00ed pevn\u00fdch p\u0159edm\u011bt\u016f, jako je maso, ryby nebo s\u00fdr, v mraz\u00e1ku. 10<\/a>{#ref-10}<\/sup><\/p>\n\n\n\n

      Syst\u00e9m funguje tak, \u017ee p\u0159ed uzav\u0159en\u00edm s\u00e1\u010dku tepeln\u00fdm uz\u00e1v\u011brem z n\u011bj fyzicky vysaje ve\u0161ker\u00fd vzduch. \u017d\u00e1dn\u00fd vzduch neznamen\u00e1 \u017e\u00e1dnou v\u00fdm\u011bnu vzduchu, co\u017e znamen\u00e1, \u017ee nedoch\u00e1z\u00ed k dehydrataci (sp\u00e1len\u00ed mrazem).<\/p>\n\n\n\n

Je tak\u00e9 naprosto nepraktick\u00fd pro tekutiny, jako jsou pol\u00e9vky nebo du\u0161en\u00e9 maso.<\/p>\n\n\n\n

      Kdy byste m\u011bli up\u0159ednostnit vakuov\u00e9 kontejnery p\u0159ed jin\u00fdmi?<\/h3>\n\n\n\n

      Zde se objevuje nov\u00e1 inovace: vakuov\u00e9 kontejnery<\/strong>. Jedn\u00e1 se o pevn\u00e9 n\u00e1doby (\u010dasto sklen\u011bn\u00e9, jako je na\u0161e \u0159ada Dragon Scale), kter\u00e9 maj\u00ed speci\u00e1ln\u00ed v\u00edko s ventilem.
