Pasina panikiro, vazhinji vedu tajaira kuchengeta mirivo mufiriji. Zvisinei, maererano nenyanzvi, pakuchengetedza mamwe marudzi emiriwo nemichero, haugoni kufungidzira nzvimbo yakaipa kupfuura firiji. Hongu, kana kwatonhora, miriwo inoibva zvishoma nezvishoma uye, somugumisiro, inoderera zvishoma nezvishoma. Asi panguva imwe cheteyo, firiji inoomesa zvinhu zvose zvinopinda mairi.
Zvino funga: munzvimbo ipi iyo zvikamu zvemiriwo yatinodya zvinokura? Izvi zvichatiudza nzira yekuzvichengeta mukicheni yedu. Kutevera pfungwa iyi, mbatatisi, pamwe nehanyanisi, karoti, nemimwe midzi yemidzi, ichaita zviri nani kunze kwefiriji-ichiti, muvharobheti ine mhepo yakanaka.
Mbatatisi yakakanyiwa, nenzira, inogona kuunza njodzi dzisingatarisirwe dzehutano: semushumo we2017 New Scientist unoti, "Haufanire kuchengeta mbatatisi mufiriji. Pakutonhora kwakadzika, enzyme inonzi invertase inoputsa sucrose kuita glucose uye fructose, iyo inogona kugadzira acrylamide panguva yekubika. Chiziviso ichi chakaitwa mukupindura yambiro kubva kuUK Food Standards Agency nezve mhedzisiro inogona kuitika yeacrylamide, iyo inonyanya kuitika kana mbatatisi yakabikwa patembiricha inopfuura 120 ° C - iyo, inofanirwa kucherechedzwa, inosanganisira ndiro zhinji, kubva kumachipisi. kugocha, muchikamu chenjodzi. . Icho chokwadi ndechekuti, maererano nekutsvagisa, acrylamide inogona kuve chinhu chinogona kumutsa marudzi ese egomarara. Nekudaro, New Scientist yakakurumidza kunyaradza vaverengi vayo nekutaura mutauriri wesangano rekutsvagisa cancer kuUK kuti "chaidzo cheacrylamide chegomarara hachisati chazivikanwa."
Asi zvakadini nemimwe miriwo yose? Sekureva kwaJane Scotter, nyanzvi yemichero nemiriwo uye muridzi wepurazi rebiodynamic, "Mutemo wegoridhe ndewekuti: kana chimwe chinhu chaibva nezuva uye chawana kutapira kwayo uye kuchena, usachiise mufiriji." Izvi zvinoreva kuti, somuenzaniso, tomate, pamwe chete nemichero yakapfava, haifaniri kuchengetwa mufiriji.
Sokutaura kunoita Jane, “michero yakapfava nemiriwo inotora kunaka kwechinyakare zviri nyore zvikuru uye pakupedzisira inorasikirwa nokutapira kwayo nokunhuwirira.” Kana iri matomatisi, izvi zvinonyanya kuoneka, nekuti enzyme inopa tomate kuravira kwayo inoparadzwa pekutanga pane tembiricha iri pasi pe4 ° C.
Asi, hongu, pane kushandiswa kwakakodzera kwefiriji. Izvi ndizvo zvinokurudzirwa naJane: “Lettuce kana kuti mashizha espinachi, kana ukasaronga kuadya pakarepo, anogona kuiswa zvakakotsekana mufiriji – kufanana nemimwe miriwo yakasvibira, anogara kwenguva refu mukutonhodza.”
Asi sei kudzivirira mashizha kubva pakuoma kana ari 90% mvura? Maererano naJane, “Mashizha acho anofanira kusukurudzwa nemvura inodziya—asi kwete kutonhora, sezvo zvichavavhundutsa, uye zvamazvirokwazvo kwete kupisa, sezvo zvichangofashaidza—ipapo zvopera, kuputira mubhegi repurasitiki, uye kuiswa mufiriji. . Iyo bhegi ichagadzira micro-climate yemashizha - uye inogona kushandiswazve kakawanda - umo ivo vacharamba vachimutsiridza kuburikidza nekutora mwando wakagadzirwa muhomwe.
