Kubvira panguva yekare, vanhu vave vachitsvaga nzira dzekuchengetedza kudya kwakasiyana-siyana pasina kurasikirwa nehutano hwavo. Munyika dzakasiyana-siyana, pasi pemamiriro akasiyana-siyana emamiriro ekunze uye unhu hwekudya, nzira nguva refu yekuchengetedza, iyo yakabudirira zvikuru iyo yaifungidzirwa ichitonhora. MuRussia yekare, nekuda kwechinangwa ichi, vakadzidza kushandisa mazamu echando akachera muchando pamigero kana kuti mashizha ane mvura yakawanda uye akaumbwa mukati memvura yakadzika. Ichando ichi hachina kunyunguduka kunyange muzhizha, kushanda sechimiro chekugadzwa kwefriji yemazuva ano.
Pari zvino, kuchengetedzwa kwemiti yakagadzirwa kuburikidza nenzira dzakasiyana-siyana dzekukanda zvinoshandiswa zvakanyanya munyika yose . Uye kwete chete nokuda kwechinangwa chekugara kwavo kwenguva refu, asiwo nekushandura mamiriro avo mukugadzirira kushandiswa, nekuparadzanisa mvura yakawanda, uyewo pakuumba michina, yekuchengetedza kunakidza uye hunodiwa hwechando hunofanirwa - ice cream, somuenzaniso.
Icho chinonyanya kukosha chekuvhenekera chinonyengera mukudzikisa kutonhora kwezasi kwechekasikopi, iyo iyo mvura iri mumiti yakasviba inoita kuti ive yakajeka, ichishandurwa kuva ice. Zvechokwadi, nekuda kwekusiyana kwehutano uye kusagadzikana kwezvokudya zvakasiyana, kune dzimwe nzira dzakasiyana- siyana uye nzira dzekugadzirisa . Nzira dzinonyanya kuzivikanwa uye dzakashandiswa dzinozivikanwa, umo kunodhura uye kudhura kwepamusoro-soro kwezvigadzirwa zvinogadzirwa - maitiro akaoma.
Munyika yemazuva ano, hutano hwakakosha hwakave hwakagadzirwa hunobvumira kuchengetedza zvakanyanya zvinhu zvinobatsira uye mavitamini zviri mune zvigadzirwa zviri pasi pekuvhenekera. Saizvozvowo, iyo iyo nzira yekukanda mimwe michero inotora nguva yakati, nokuti nyama, hove, gungwa, majiro, miriwo, mushwa, semiti-michina inogadzirisa zvakasiyana nekuderera kwekushisa. Mukuwedzera, nguva yenguva inopisa inobatwa nehupamhi hwepakiti. Chigadzirwa chacho chakanyorohwa kana chakati mukati mawo kutonhora kunodonha kusvika -6 degrees Celsius.
Kuisa zvigadzirwa mazuva ano, nzira mbiri mbiri dzinoshandiswa : mhepo inopisa uye kushandiswa kwefrijiji. Nzira yekutanga ndiyo nzira yemakore makumi manomwe yekudengenyeka. Kubatsira kwayo kukuru ndechokuti hapana chidikanwi chekuchengetedza, uye nekuda kwehupamhi hwekuvhenekera kukurumidza kusagadzikana uye kunakirwa kwemiti yakasviba zvinenge zvisingasiyane nezvitsva. Inyanzvi yekutengesa kunotyisa inoshandiswawo mukubudirira kwezvokugadzirira zvakagadzirirwa, izvo, zvisati zvashanda, zvinoda kungopisa muvheni ye microwave.
Nzira dzakakomba dzekuvhenekera dzinoshandiswawo nekukurumidza kushandiswa kwezvinhu zvakagadzirwa nemafungiro akajeka, mukushandiswa kwokuti mushizha haubvumirwi - gungwa rezvokudya, semiti yakagadzirwa nemichero kubva kune michero yakasvibirira, hove dzehove, mabriji nemichero. Nenzira iyi yekusviba, michina yehutano inowanikwa mukushambadzira kwemhepo. Mishonga uye zvipembenene zvekare - pastes, pastas, ice cream - dzakanamirwa mune mamwe majeko akakosha anonzi friezers.
Imwe nzira inoshandisa kuporesa inosanganisira kugadzirwa kwegyogenic, panguva iyo zvigadzirwa, pahutano hwakananga, zvakachengetedzwa zvakachengeteka zvakachengetedza zvinhu. Inodawo kuti zvakakwana kuswedera pedyo, kuti kuderedze mari, nzira yakabatanidzwa yekudziya inoshandiswa: kutanga nekubatsira kwegyogenic zvinhu, uye zvakare nemhepo inotonhora. Muenzaniso wemidziyo yakadai inogona kushanda sefriji nefriji inobva kune nitrogen yemvura.
Kukurumidza kufambira mberi kwesayenzi gore negore kunowedzera kune ikozvino yakashandiswa nzira yekukanda chimwe chinhu chitsva, kuvandudza nzira yacho pachayo uye nzira dzekuitungamirira kuti kuwedzere kukosha uye kuwedzerwa kwezvokudya zvemafuta akaoma. Uye rimwe zuva, chokwadi, richawanikwa rakakosha nzira yakasanganiswa , kushandiswa kwekupedzisira kuchagumisa mutsara pakati pezvigadzirwa zvitsva uye izvo zvinotarirwa nechando.
