\u012evadas \u012f vandens kiek\u012f vaisiuose ir dar\u017eov\u0117se<\/strong><\/h2><\/div>\n\n\n\n

Vanduo yra pagrindin\u0117 \u0161vie\u017ei\u0173 vaisi\u0173 ir dar\u017eovi\u0173 sudedamoji dalis, jo kiekis paprastai svyruoja nuo 70% iki 95%. Vanduo vaisiuose ir dar\u017eov\u0117se b\u016bna trij\u0173 skirting\u0173 b\u016bsen\u0173: laisvasis vanduo, koloidi\u0161kai suri\u0161tas vanduo ir chemi\u0161kai suri\u0161tas vanduo. Laisvasis vanduo vaisiuose ir dar\u017eov\u0117se juda kapiliarais ir osmoso b\u016bdu, yra judresnis ir lengvai pa\u0161alinamas d\u017eiovinant. Dalis su koloidiniais junginiais susieto vandens gali b\u016bti pa\u0161alinta d\u017eiovinant, o chemi\u0161kai susieto vandens d\u017eiovinant paprastai pa\u0161alinti ne\u012fmanoma.<\/p>\n\n\n\n

Kod\u0117l d\u017eioviname vaisius ir dar\u017eoves?<\/strong><\/h2><\/div>\n\n\n\n

Pagrindin\u0117 vaisi\u0173 ir dar\u017eovi\u0173 d\u017eiovinimo prie\u017eastis - i\u0161vengti puvimo ir prailginti j\u0173 galiojimo laik\u0105. Principas yra tas, kad suri\u0161tas vanduo, kurio negalima pa\u0161alinti d\u017eiovinant, yra pusiausvyros dr\u0117gm\u0117s kiekis vaisi\u0173 ar dar\u017eovi\u0173 audiniuose d\u017eiovinimo s\u0105lygomis. Dehidratacijos d\u017eiovinimo procese vaisiai ir dar\u017eov\u0117s i\u0161 dr\u0117gnos b\u016bsenos virsta sausomis, pa\u0161alinant didel\u012f kiek\u012f laisvo vandens ir \u0161iek tiek koloidinio suri\u0161to vandens. Suma\u017e\u0117jus vidiniam dr\u0117gm\u0117s kiekiui, suma\u017e\u0117ja ir vandens aktyvumas, tod\u0117l vaisiuose ir dar\u017eov\u0117se slopinamas arba stabdomas mikrob\u0173 augimas ir ferment\u0173 aktyvumas, taip pailginant j\u0173 laikymo trukm\u0119.<\/p>\n\n\n\n

Pagrindinis vaisi\u0173 ir dar\u017eovi\u0173 d\u017eiovinimo procesas<\/strong><\/h2><\/div>\n\n\n\n

Pagrindinio proceso metu \u0161iluma i\u0161 \u0161ilumos \u0161altinio perduodama \u012f vaisius ir dar\u017eoves, tod\u0117l dr\u0117gm\u0117 audiniuose ir l\u0105stel\u0117se nuolat migruoja ir i\u0161garuoja i\u0161 j\u0173 pavir\u0161iaus, taip pasiekiamas d\u017eiovinimo efektas. Dehidratuoti vaisiai ir dar\u017eov\u0117s i\u0161laiko did\u017ei\u0105j\u0105 dal\u012f maistini\u0173 med\u017eiag\u0173, ir, nepaisant tam tikr\u0173 skonio ir i\u0161vaizdos skirtum\u0173, palyginti su \u0161vie\u017eiais vaisiais ir dar\u017eov\u0117mis, d\u0117l ma\u017eesnio dyd\u017eio, ma\u017eesnio svorio ir patogesnio transportavimo jie yra populiar\u016bs tarp vartotoj\u0173.<\/p>\n\n\n\n

Bendrieji d\u017eiovinimo b\u016bdai<\/strong><\/h2><\/div>\n\n\n\n
    \n
  1. D\u017eiovinimas saul\u0117s energija<\/strong>: Tai seniausias d\u017eiovinimo b\u016bdas, kai vaisiams ir dar\u017eov\u0117ms d\u017eiovinti naudojama saul\u0117s energija. Jis yra labai ekonomi\u0161kas, nes j\u012f reikia tik rankomis pjaustyti ir d\u0117ti. Ta\u010diau d\u0117l l\u0117to d\u017eiovinimo grei\u010dio ir dideli\u0173 produkto spalvos ir i\u0161vaizdos poky\u010di\u0173 jis netinka pramoninei masinei gamybai, o labiau tinka nam\u0173 \u016bkiui arba nedidelio masto gamybai.<\/li>\n\n\n\n
  2. D\u017eiovinimas kar\u0161tu oru<\/strong>: \u0160is metodas yra pla\u010diausiai naudojamas d\u0117l nedidel\u0117s kainos ir paprasto naudojimo. Jame kaip d\u017eiovinimo terp\u0117 naudojamas kar\u0161tas oras, kuris i\u0161garina pavir\u0161iaus dr\u0117gm\u0119 ir palaipsniui perkelia dr\u0117gm\u0119 i\u0161 vidaus \u012f med\u017eiagos pavir\u0161i\u0173. D\u017eiovinimo metu nuolat kylanti pavir\u0161iaus temperat\u016bra sukuria temperat\u016bros gradient\u0105, kuris gali trukdyti dr\u0117gm\u0117s migracijai ir sul\u0117tinti d\u017eiovinimo proces\u0105. Nors d\u017eiovinimas kar\u0161tu oru yra veiksmingas, d\u0117l jo gali pakisti vaisi\u0173 ir dar\u017eovi\u0173 spalva ir prarasti vidini\u0173 maistini\u0173 med\u017eiag\u0173, be to, gali kilti toki\u0173 problem\u0173 kaip ilgas d\u017eiovinimo laikas, ma\u017eas energijos vartojimo efektyvumas ir prastesn\u0117 produkto kokyb\u0117 laikymo metu.<\/li>\n\n\n\n
  3. D\u017eiovinimas mikrobang\u0173 krosnel\u0117je<\/strong>: \u0160is metodas apima polini\u0173 molekuli\u0173, pavyzd\u017eiui, vandens, orientavim\u0105 ir greit\u0105 svyravim\u0105 mikrobang\u0173 elektromagnetiniame lauke, d\u0117l trinties s\u0105veikos sukuriant daug \u0161ilumos. Mikrobangos pirmenyb\u0119 teikia vandens molekuli\u0173 kaitinimui, tod\u0117l dr\u0117gm\u0117 migruoja i\u0161 vidaus \u012f i\u0161or\u0119, o tada i\u0161garuoja ir greitai i\u0161d\u017ei\u016bsta. Privalumai - didelis d\u017eiovinimo greitis ir vienalaikis d\u017eiovinimas viduje ir i\u0161or\u0117je. Ta\u010diau didelis energijos suvartojimas vienam vienetui, didel\u0117s pradin\u0117s investicijos \u012f \u012frang\u0105 ir galimas mikrobang\u0173 spinduliuot\u0117s keliamas pavojus sveikatai yra svarb\u016bs tr\u016bkumai. Kai kuriose \u0161alyse d\u0117l susir\u016bpinimo sveikata maisto \u0161ildymas mikrobang\u0173 krosnel\u0117mis yra apribotas.<\/li>\n\n\n\n
  4. D\u017eiovinimas u\u017e\u0161aldant<\/strong>: Taikant \u0161\u012f metod\u0105 med\u017eiagoje esanti dr\u0117gm\u0117 greitai u\u017e\u0161aldoma iki ledo, o tada vanduo pa\u0161alinamas sublimuojant auk\u0161to vakuumo s\u0105lygomis, esant \u017eemai temperat\u016brai. Liofilizuoti produktai i\u0161laiko savo form\u0105 ir vidin\u0119 strukt\u016br\u0105, pasi\u017eymi puikia rehidratacijos kokybe ir i\u0161saugo maistines med\u017eiagas, tod\u0117l ypa\u010d tinka d\u017eiovinti kar\u0161\u010diui jautrius ir oksiduojamus maisto produktus. Nepaisant to, kad gaminami auk\u0161tos kokyb\u0117s d\u017eiovinti produktai, liofilizacij\u0105 riboja l\u0117tas greitis, didel\u0117s energijos s\u0105naudos vienam vienetui ir didel\u0117s investicijos \u012f \u012frang\u0105, tod\u0117l ma\u017eoms ir vidutin\u0117ms \u012fmon\u0117ms ji ma\u017eiau tinkama.<\/li>\n\n\n\n
  5. Osmosinis d\u017eiovinimas<\/strong>: Taikant \u0161\u012f metod\u0105 med\u017eiagos panardinamos \u012f tokius tirpalus kaip cukrus ar s\u016brus vanduo, kurie osmoso b\u016bdu pa\u0161alina dr\u0117gm\u0119. Osmotinis dehidratavimas yra greitas ir minimaliai paveikia med\u017eiagos strukt\u016brin\u012f vientisum\u0105, veiksmingai i\u0161saugo pirmin\u0119 l\u0105steli\u0173 strukt\u016br\u0105, spalv\u0105, skon\u012f ir maisting\u0105sias med\u017eiagas, taip pat stabdo mikrob\u0173 augim\u0105 ir prailgina galiojimo laik\u0105. \u0160is metodas vis\u0173 pirma naudojamas cukruotiems vaisiams ir marinuotoms dar\u017eov\u0117ms gaminti.<\/li>\n\n\n\n
  6. \u0160ilumos siurblio d\u017eiovinimas<\/strong>: \u0160i technologija i\u0161gauna \u0161ilum\u0105 i\u0161 \u017eemos temperat\u016bros \u0161altinio ir efektyviai naudoja j\u0105 auk\u0161tesn\u0117je temperat\u016broje. Pastaruoju metu \u0161ilumos siurbli\u0173 technologija vis da\u017eniau taikoma vandens produktams, vaistams ir \u017eem\u0117s \u016bkio \u0161alutiniams produktams d\u017eiovinti. Jos principai pana\u0161\u016bs \u012f d\u017eiovinimo kar\u0161tu oru principus, ta\u010diau naudojami skirtingi \u0161ilumos \u0161altiniai, tod\u0117l ji pasi\u017eymi tokiais privalumais kaip auk\u0161tos kokyb\u0117s d\u017eiovinti produktai, energijos taupymas ir tar\u0161os nebuvimas.<\/li>\n\n\n\n
  7. D\u017eiovinimas infraraudonaisiais spinduliais<\/strong>: Infraraudonieji spinduliai tiesiogiai kaitina med\u017eiagos vandens molekules, tod\u0117l pakyla temperat\u016bra ir i\u0161garuoja dr\u0117gm\u0117, taip pasiekiama dehidratacija. Principas pagr\u012fstas dr\u0117gm\u0117s sklaida i\u0161 vidaus \u012f vaisiaus ar dar\u017eov\u0117s pavir\u0161i\u0173, kur ji i\u0161garuoja \u012f aplink\u0105. Infraraudonieji spinduliai \u012f vaisius ir dar\u017eoves gali prasiskverbti iki tam tikro gylio<\/li>\n<\/ol>\n\n\n\n
