Alternativou jsou \u0161etrn\u011bj\u0161\u00ed metody jako dehydratace a su\u0161en\u00ed mrazem.

Zde jsou n\u011bkter\u00e9 podobnosti, rozd\u00edly a v\u00fdhody dehydrovan\u00fdch a mrazem su\u0161en\u00fdch potravin.<\/span><\/p>\n

Co je dehydratace?<\/span><\/h2>\n

Dehydratace je proces konzervace potravin, kter\u00fd odstra\u0148uje vlhkost z potravin t\u00edm, \u017ee je vystavuje horku.<\/span><\/p>\n

Zpracov\u00e1van\u00e9 potraviny se nakr\u00e1jej\u00ed pl\u00e1tky nebo na kosti\u010dky a um\u00edst\u00ed do su\u0161i\u010dky, kter\u00e1 na potraviny n\u011bkolik hodin fouk\u00e1 hork\u00fd vzduch. Teplo zp\u016fsobuje vypa\u0159ov\u00e1n\u00ed vody v potravin\u00e1ch, \u010d\u00edm\u017e se v\u00fdsledn\u00fd produkt st\u00e1v\u00e1 such\u00fdm a k\u0159ehk\u00fdm.<\/span><\/p>\n

N\u011bkter\u00e9 potraviny jako nap\u0159\u00edklad houby se jen rozlo\u017e\u00ed na t\u00e1cky a nechaj\u00ed su\u0161it na slunci nebo v interi\u00e9ru po del\u0161\u00ed dobu.<\/span><\/p>\n

Dehydrovan\u00e9 j\u00eddlo nab\u00edz\u00ed ur\u010dit\u00e9 v\u00fdhody. Ve srovn\u00e1n\u00ed s jin\u00fdmi metodami konzervov\u00e1n\u00ed jsou dehydrovan\u00e9 potraviny snaz\u0161\u00ed a zab\u00edraj\u00ed m\u00e9n\u011b m\u00edsta ne\u017e \u010derstv\u00e9 potraviny, d\u00edky \u010demu\u017e jsou ide\u00e1ln\u00ed pro v\u00fdlety s batohem nebo kemp.<\/span><\/p>\n

Kone\u010dn\u011b dehydrovan\u00e9 potraviny lze rehydratovat vodou, d\u00edky \u010demu\u017e jsou v\u0161estrann\u00e9 a vhodn\u00e9 pro va\u0159en\u00ed.<\/span><\/p>\n

M\u00e1te-li su\u0161i\u010dku, je snadn\u00e9 a levn\u00e9 su\u0161it r\u016fzn\u00e9 bylinky, ovoce a zeleninu doma.<\/span><\/p>\n

Co je lyofilizace, respektive su\u0161en\u00ed mrazem?<\/span><\/h2>\n

Lyofilizace je proces konzervace potravin, kter\u00fd odstra\u0148uje vlhkost z potravin zmrazen\u00edm a n\u00e1sledn\u00fdm vakuov\u00e1n\u00edm. J\u00eddlo se um\u00edst\u00ed na podnosy a zmraz\u00ed se na p\u0159ibli\u017en\u011b -40 stup\u0148\u016f Celsia.<\/span><\/p>\n

Po zmrazen\u00ed se potraviny p\u0159esunou do vakuov\u00e9 komory, ve kter\u00e9 se sn\u00ed\u017e\u00ed tlak. Zmrzl\u00e1 voda v potravin\u00e1ch tak sublimuje (p\u0159\u00edmo se m\u011bn\u00ed z pevn\u00e9 l\u00e1tky na plynnou), ani\u017e by p\u0159e\u0161la p\u0159es kapalnou f\u00e1zi.<\/span><\/p>\n

Vakuum tak\u00e9 vyt\u00e1hne vodn\u00ed p\u00e1ru z komory, \u010d\u00edm\u017e z\u016fstane j\u00eddlo such\u00e9 a leh\u010d\u00ed.<\/span><\/p>\n

Lyofilizace tak\u00e9 nab\u00edz\u00ed v\u00fdhody oproti jin\u00fdm metod\u00e1m konzervov\u00e1n\u00ed potravin. L\u00e9pe zachov\u00e1v\u00e1 nutri\u010dn\u00ed obsah potravin, proto\u017ee n\u00edzk\u00e1 teplota a kr\u00e1tk\u00e1 doba su\u0161en\u00ed minimalizuj\u00ed ztr\u00e1tu vitam\u00edn\u016f a dal\u0161\u00edch \u017eivin.<\/span><\/p>\n

Lyofilizovan\u00e9 potraviny jsou tak\u00e9 mnohem snaz\u0161\u00ed a snadno se p\u0159epravuj\u00ed, proto\u017ee v\u011bt\u0161ina vody byla odstran\u011bna.<\/span><\/p>\n

No a kone\u010dn\u011b, mrazem su\u0161en\u00e9 potraviny maj\u00ed velmi dlouhou trvanlivost. N\u011bkter\u00e9 mrazem su\u0161en\u00e9 potraviny lze skladovat a\u017e 25 let.<\/span><\/p>\n

Podobnosti mezi lyofilizovan\u00fdmi potravinami a dehydrovan\u00fdmi potravinami<\/span><\/h2>\n

Lyofilizovan\u00e9 i dehydrovan\u00e9 potraviny odstra\u0148uj\u00ed vlhkost z potravin, aby se zachovaly d\u00e9le ve srovn\u00e1n\u00ed s jin\u00fdmi metodami. Mezi t\u011bmito dv\u011bma procesy jsou v\u0161ak n\u011bkter\u00e9 kl\u00ed\u010dov\u00e9 rozd\u00edly.<\/span><\/p>\n

V\u00fdroba lyofilizovan\u00fdch potravin je dra\u017e\u0161\u00ed ne\u017e v\u00fdroba dehydrovan\u00fdch potravin, proto\u017ee vy\u017eaduj\u00ed speci\u00e1ln\u00ed vybaven\u00ed a del\u0161\u00ed dobu su\u0161en\u00ed.<\/span><\/p>\n

Jednou z v\u00fdhod lyofilizovan\u00fdch potravin v\u0161ak je, \u017ee si zachov\u00e1vaj\u00ed v\u00edce sv\u00e9 p\u016fvodn\u00ed chuti, textury a nutri\u010dn\u00edho obsahu ne\u017e dehydrovan\u00e9 potraviny.<\/span><\/p>\n

V\u00fdhody lyofilizovan\u00fdch a dehydrovan\u00fdch potravin<\/span><\/h2>\n

Lyofilizovan\u00e9 i dehydrovan\u00e9 potraviny nab\u00edzej\u00ed ur\u010dit\u00e9 v\u00fdhody.<\/span><\/p>\n

Oba jsou leh\u010d\u00ed a snadno se p\u0159epravuj\u00ed. Oba druhy potravin maj\u00ed tak\u00e9 dlouhou trvanlivost, d\u00edky \u010demu\u017e jsou spolehliv\u00fdm zdrojem potravy v p\u0159\u00edpad\u011b nouze.<\/span><\/p>\n

Ostatn\u011b ob\u011b jsou v\u0161estrann\u00e9 a pohodln\u00e9, proto\u017ee je m\u016f\u017eete rehydratovat vodou nebo pou\u017e\u00edt v receptech, jako jsou \u010derstv\u00e9 potraviny.<\/span><\/p>\n

Z hlediska zachov\u00e1n\u00ed nutri\u010dn\u00edch l\u00e1tek jsou na tom lyofilizovan\u00e9 potraviny o n\u011bco l\u00e9pe p\u0159ed dehydratovan\u00fdmi potravinami.<\/span><\/p>\n
