Sezvo tii chirimwa chechisikigo, zvimwe zvezvayo zvechisikigo zvinotungamira kune yakasimba kurongedza tii.
Naizvozvo, kurongedza tii kune zvinodiwa zve anti oxidation, hunyoro-uchapupu, yakanyanya tembiricha kuramba, shading uye gasi kuramba.
Anti oxidation
Yakawandisa okisijeni yemukati mupakeji inotungamira kune oxidative kudzikira kwezvimwe zvikamu mutii.Semuenzaniso, lipid zvinhu zvinosanganisa neokisijeni munzvimbo kuti ibudise aldehydes nemaketoni, zvichigadzira kunhuhwirira kwakashata.Naizvozvo, iyo okisijeni yemukati mukurongedza tii inofanirwa kudzorwa zvinobudirira pazasi 1%.Panyaya yekurongedza tekinoroji, inflatable kurongedza kana vacuum packaging inogona kushandiswa kuderedza kuvapo kweokisijeni.Iyo tekinoroji yekuputira tekinoroji inzira yekurongedza inoisa tii mune yakapfava firimu yekuisa bhegi (kana aluminium foil vacuum bag) ine yakanaka air tightness, inobvisa mhepo mubhegi panguva yekurongedza, inogadzira imwe dhigirii yevacuum, uye yobva yaisimbisa;Inflatable packaging tekinoroji ndeyekuzadza inert magasi akadai senitrogen kana deoxidizer uchiburitsa mweya, kuitira kuchengetedza kugadzikana kweruvara, kunhuhwirira uye kuravira kwetii uye kuchengetedza mhando yayo yepakutanga.
High tembiricha kuramba.
Tembiricha chinhu chakakosha chinokanganisa kunaka kwetii.Musiyano wetembiricha ndeye 10 ℃, uye chiyero chemakemikari kuita 3 ~ 5 nguva dzakasiyana.Tea ichawedzera oxidation yezviri mukati pasi pekupisa kwakanyanya, zvichikonzera kuderedzwa nekukurumidza kwepolyphenols nezvimwe zvinhu zvinoshanda uye nekukurumidza kuderera kwemhando.Zvinoenderana nekuita, tembiricha yekuchengetedza tii iri pasi pe5 ℃ ndiyo yakanyanya kunaka.Kana tembiricha iri 10 ~ 15 ℃, ruvara rwetii runodzikira zvishoma nezvishoma, uye mhedzisiro yemuvara inogonawo kuchengetedzwa.Kana tembiricha yadarika 25 ℃, ruvara rwetii runochinja nekukurumidza.Nokudaro, tei yakakodzera kuchengetedzwa pakudzika kwakadzika.
mwando-uchapupu
Mvura yemukati mutii ndiyo yepakati yekuchinja kwebiochemical mutii, uye yakaderera mvura yemukati inobatsira kuchengetedza kunaka kwetii.Mvura iri muiyi haifaniri kudarika 5%, uye 3% ndiyo yakanakisisa yekuchengetedza kwenguva refu, kana zvisina kudaro ascorbic acid iri muteyi iri nyore kuora, uye ruvara, kunhuhwirira, uye kuravira kwetiyi kuchachinja, kunyanya pakupisa kwepamusoro, chiyero chekuora chichawedzerwa.Naizvozvo, kana tichirongedza, isu tinogona kusarudza iyo inoumbwa firimu ine yakanaka-inoratidza hunyoro kuita, senge aruminiyamu foil kana aluminium foil evaporation firimu sechinhu chakakosha pakurongedza-unyoro.
shading
Chiedza chinogona kukurudzira oxidation ye chlorophyll, lipid uye zvimwe zvinhu mutii, kuwedzera huwandu hwe glutaraldehyde, propionaldehyde uye zvimwe zvinhu zvinonhuwa mutii, uye kukurumidza kuchembera kwetii.Naizvozvo, pakurongedza tii, mwenje unofanirwa kudzivirirwa kudzivirira iyo photocatalytic maitiro echlorophyll, lipid uye zvimwe zvikamu.Uye zvakare, ultraviolet mwaranzi zvakare chinhu chakakosha chinoita kuti tii iwedzere.Kugadzirisa dambudziko iri, shading packaging tekinoroji inogona kushandiswa.
Choke
Kunhuhwirira kwetii kuri nyore kuparara, uye kuri panjodzi yekufurirwa nekunhuhwirira kwekunze, kunyanya iyo yakasara inonyungudutsa yecomposite membrane uye kunhuhwirira kwakaodzwa nekupisa chisimbiso kurapwa kuchakanganisa kunaka kwetii, izvo zvinokanganisa kunhuhwirira kwetii.Naizvozvo, kurongedza tii kunofanirwa kudzivirira kupukunyuka kunhuhwirira kubva pakurongedza uye kunhuhwirira kunhuhwirira kubva kunze.Tii yekurongedza zvinhu zvinofanirwa kunge zvine mamwe gasi anodzivirira zvivakwa.
