Kodi ma jenereta a nthunzi angatalikitse bwanji moyo wa alumali wa chakudya pambuyo polongedza vacuum?

Chakudya chili ndi alumali yake. Ngati simusamala kusunga chakudya, mabakiteriya amachitika ndikupangitsa kuti chakudya chiwonongeke. Zakudya zina zowonongeka sizingadyedwe. Pofuna kusunga zakudya kwa nthawi yayitali, makampani azakudya samangowonjezera zoteteza kuti azitalikitsa moyo wa alumali, komanso amagwiritsa ntchito injini za nthunzi kuti apange nthunzi kuti asawononge chakudya pambuyo polongedza m'malo opanda mpweya. Mpweya womwe uli mu phukusi la chakudya umachotsedwa ndikusindikizidwa kuti ukhalebe mpweya mu phukusi. Ngati ili yochepa, padzakhala mpweya wochepa, ndipo tizilombo toyambitsa matenda sitingathe kukhala ndi moyo. Mwanjira iyi, chakudyacho chikhoza kukwaniritsa ntchito yosungira mwatsopano, ndipo moyo wa alumali wa chakudya ukhoza kukulitsidwa.

Nthawi zambiri, zakudya zophikidwa monga nyama zimatha kubereka mabakiteriya chifukwa zimakhala ndi chinyezi komanso mapuloteni komanso zakudya zina. Popanda kuletsa kutsekereza pambuyo polongedza vacuum, nyama yophikayo imakhalabe ndi mabakiteriya isanapake, ndipo idzawonongabe nyama yophikidwa mu vacuum m'malo opanda okosijeni. Ndiye mafakitale ambiri azakudya adzasankha kuchitanso zoletsa kutentha kwambiri ndi ma jenereta a nthunzi. Chakudya chochitidwa motere chikhala nthawi yayitali.

Musanayambe kuyika vacuum, chakudya chimakhala ndi mabakiteriya, choncho chakudyacho chiyenera kutsekedwa. Chifukwa chake kutentha kwamitundu yosiyanasiyana yazakudya kumakhala kosiyana. Mwachitsanzo, kutseketsa kwa chakudya chophikidwa sikuyenera kupitirira madigiri 100 Celsius, pamene kutseketsa kwa zakudya zina kuyenera kupitirira madigiri 100 Celsius kupha mabakiteriya. Jenereta ya nthunzi imatha kusinthidwa molingana ndi zosowa zosiyanasiyana kuti ikwaniritse kutentha kwamitundu yosiyanasiyana ya ma vacuum chakudya. Mwanjira imeneyi, moyo wa alumali wa chakudya ukhoza kukulitsidwa.

Winawake adayesanso chimodzimodzi ndipo adapeza kuti ngati palibe kutsekereza, zakudya zina zimachulukitsa kuchuluka kwa kuwonongeka pambuyo polongedza vacuum. Komabe, ngati njira yolera yotseketsa imatengedwa pambuyo pakuyika vacuum, malinga ndi zofunikira zosiyanasiyana, jenereta ya Nobest yotentha kwambiri yoletsa kutsekereza nthunzi imatha Mogwira kukulitsa alumali moyo wa vacuum mmatumba, kuyambira masiku 15 mpaka masiku 360. Mwachitsanzo, mkaka akhoza kusungidwa firiji pasanathe masiku 15 pambuyo vacuum kulongedza ndi yotseketsa nthunzi; Nkhuku zosuta zimatha kusungidwa kwa miyezi 6-12 kapena kupitilira apo mutatha kuyika vacuum ndi kutsekereza kotentha kwambiri kwa nthunzi.
