Chakudya cha m'zitini ndi chatsopano kwambiri
Chifukwa chachikulu chomwe anthu ambiri amasiyira kudya zakudya zam'chitini ndi chakuti amaganiza kuti chakudya cham'chitini si chatsopano.
Tsankho limeneli limachokera ku malingaliro a ogula okhudza chakudya cha m'zitini, zomwe zimawapangitsa kuti aziganiza kuti nthawi yayitali yosungira chakudya ndi yosatha. Komabe, chakudya cha m'zitini ndi chakudya chatsopano chomwe chimakhala nthawi yayitali komanso chosatha.
1. Zipangizo zatsopano
Pofuna kuonetsetsa kuti chakudya cha m'zitini chili chatsopano, opanga chakudya cha m'zitini amasankha mosamala chakudya chatsopano mu nyengo ino. Makampani ena amakhazikitsa malo awo obzala ndi kusodza, ndikukhazikitsa mafakitale pafupi kuti akonze zokolola.
2. Chakudya cha m'zitini chimakhala ndi nthawi yayitali yosungiramo zinthu
Chifukwa chomwe chakudya cha m'zitini chimasungidwira nthawi yayitali ndichakuti chakudya cha m'zitini chimatsekedwa ndi vacuum ndipo chimayeretsedwa ndi kutentha kwambiri popanga. Malo osungira vacuum amaletsa chakudya chotenthetsera kutentha kwambiri kuti chisakhudze mabakiteriya omwe ali mumlengalenga, zomwe zimapangitsa kuti chakudyacho chisadetsedwe ndi mabakiteriya omwe ali komweko.
3. Palibe chifukwa chosungira zinthu zonse
Mu 1810, pamene chakudya cha m'zitini chinayamba, zinthu zamakono zosungira chakudya monga sorbic acid ndi benzoic acid sizinapangidwe konse. Pofuna kukulitsa nthawi yosungira chakudya, anthu ankagwiritsa ntchito ukadaulo woika chakudya m'zitini kuti apange zitini.
Ponena za chakudya cha m'zitini, anthu ambiri amayankha koyamba kuti "akane". Anthu nthawi zonse amaganiza kuti zinthu zosungira zimatha kutalikitsa nthawi yosungira chakudya, ndipo chakudya cha m'zitini nthawi zambiri chimakhala ndi nthawi yayitali yosungira chakudya, kotero anthu ambiri amaganiza molakwika kuti chakudya cha m'zitini chiyenera kuti chinawonjezera zinthu zambiri zosungira. Kodi chakudya cha m'zitini chimawonjezeredwa ndi zinthu zambiri zosungira, monga momwe anthu amanenera?
zosungira? Ayi konse! Mu 1810, pamene zitini zinabadwa, chifukwa ukadaulo wopanga sunali wokwanira, zinali zosatheka kupanga malo osungiramo zinthu zopanda mpweya. Pofuna kukulitsa nthawi yosungiramo chakudya, opanga panthawiyo ankatha kuwonjezera zinthu zosungiramo zinthu. Tsopano mu 2020, kukula kwa sayansi ndi ukadaulo kwakhala kwakukulu kwambiri. Anthu amatha kupanga mwaluso malo osungiramo zinthu zopanda mpweya kuti atsimikizire ukhondo wa chakudya, kuti tizilombo totsala tisakule popanda mpweya, kuti chakudya chomwe chili m'zitini chisungidwe kwa nthawi yayitali.
Chifukwa chake, ndi ukadaulo wamakono, palibe chifukwa chowonjezera zinthu zosungira. Pazakudya zam'chitini, anthu ambiri akadali ndi kusamvetsetsana kwakukulu. Nazi njira zina zothetsera vutoli:
1. Chakudya cha m'zitini sichili chatsopano?
Chifukwa chachikulu chomwe anthu ambiri sakonda chakudya cha m'zitini ndichakuti amaganiza kuti chakudya cha m'zitini si chatsopano. Anthu ambiri mosadziwa amayerekezera "kukhala nthawi yayitali" ndi "chosakhala chatsopano", zomwe kwenikweni sizolondola. Nthawi zambiri, chakudya cha m'zitini chimakhala chatsopano kuposa zipatso ndi ndiwo zamasamba zomwe mumagula ku supermarket.
Mafakitale ambiri oika m'zitini amakhazikitsa malo awo obzala pafupi ndi mafakitale. Tiyeni titenge tomato wopangidwa m'zitini mwachitsanzo: kwenikweni, zimatenga nthawi yochepa kuposa tsiku limodzi kuti tisankhe, kupanga ndikutseka tomato. Kodi zingakhale bwanji zatsopano kuposa zipatso ndi ndiwo zamasamba zambiri munthawi yochepa! Kupatula apo, ogula asanagule, zipatso ndi ndiwo zamasamba zatsopano zinali zitakumana kale ndi vuto la 9981 ndipo zidataya michere yambiri. sinthani Ndipotu, chakudya chambiri chopangidwa m'zitini chimakhala ndi thanzi kuposa chakudya chatsopano chomwe mumadya.
2.Kodi nthawi yayitali yogwiritsira ntchito, chikuchitika ndi chiyani?
Tatchula kale chimodzi mwa zifukwa zomwe zimapangitsa kuti zitini zizikhala nthawi yayitali, ndiko kuti, malo osungira zinthu zotayidwa, ndipo chachiwiri ndi kuyeretsa kutentha kwambiri. Kuyeretsa kutentha kwambiri, komwe kumadziwikanso kuti pasteurization, kumalola chakudya choyeretsera kutentha kwambiri kuti chisakhudzenso mabakiteriya mumlengalenga, zomwe zimatchedwa kuti kuteteza chakudya kuti chisadetsedwe ndi mabakiteriya ochokera ku gwero.
3. Chakudya cha m'zitini sichili ndi thanzi labwino ngati chakudya chatsopano!
Kusowa zakudya ndi chifukwa chachiwiri chomwe ogula amakana kugula chakudya cha m'zitini. Kodi chakudya cha m'zitinicho chili ndi thanzi? Ndipotu, kutentha kwa nyama ya m'zitini ndi pafupifupi 120 ℃, kutentha kwa ndiwo zamasamba ndi zipatso za m'zitini sikoposa 100 ℃, pomwe kutentha kwa kuphika kwathu tsiku ndi tsiku ndi koposa 300 ℃. Chifukwa chake, kutayika kwa mavitamini panthawi yophika kudzaposa kutayika kwa kukazinga, kukazinga, kukazinga ndi kuwiritsa? Kuphatikiza apo, umboni wodalirika kwambiri woweruza kutsopano kwa chakudya ndikuwona kuchuluka kwa michere yoyambirira mu chakudya.
