Green tea inonyanya kuve nezvikamu zvakaita se ascorbic acid, tannins, polyphenolic compounds, catechin mafuta uye carotenoids.Izvi zvinongedzo zvinokonzeresa kukanganisa nekuda kweokisijeni, tembiricha, hunyoro, chiedza uye kunhuhwirira kwezvakatipoteredza.Naizvozvo, pakurongedza tii, pesvedzero yezvinhu zviri pamusoro inofanira kudzikiswa kana kudzivirirwa, uye izvo zvinodiwa ndezvizvi:
Kuramba kwehunyoro
Mvura yemvura mu tea haifaniri kudarika 5%, uye 3% ndiyo yakanakisisa yekuchengetedza kwenguva refu;kana zvisina kudaro, iyo ascorbic acid iri muteyi ichaora nyore nyore, uye ruvara, kunhuhwirira uye kuravira kwetiyi kuchachinja, kunyanya pakupisa kwepamusoro., mwero wekuderera uchawedzerwa.Naizvozvo, zvekurongedza zvinhu zvine hunyoro-hupupuriro kuita zvinogona kusarudzirwa kunyorova-kurongedza kurongedza, senge akaumbwa mafirimu akavakirwa paaluminium foil kana aluminium foil evaporated firimu, inogona kuve yakanyanya hunyoro-humbowo.Kunyanya kutarisisa kunofanirwa kubhadharwa kune hunyoro-huchapupu kurapwa kweblack tea packaging.
Oxidation kuramba
Iyo okisijeni yemukati mupakeji inofanirwa kudzorwa pazasi 1%.Okisijeni yakawandisa inokonzeresa kuti zvimwe zvikamu mutii zviore.Semuyenzaniso, ascorbic asidhi nyore oxidized mu deoxyascorbic asidhi, uye mberi kusanganisa pamwe amino asidhi kupinda pigment reaction, izvo zvinoita kuti kuravira tii kuwedzera.Sezvo mafuta etii aine huwandu hwakati wandei hweunsaturated fatty acids, akadaro unsaturated fatty acids anogona kuve oxidized oxidized kugadzira carbonyl makomisheni akadai sealdehydes uye ketones uye enol makomponi, ayo anogona zvakare kuita kuti kunhuhwirira kweti kunyangarike, iyo astringency inova yakareruka, uye ruvara runova rima.
Shading
Sezvo tii iine chlorophyll nezvimwe zvinhu, pakurongedza mashizha etii, mwenje unofanirwa kudzivirirwa kudzivirira kuita kwephotocatalytic kwechlorophyll nezvimwe zvinhu.Mukuwedzera, ultraviolet rays zvakare chinhu chakakosha mukukonzera kuora kwemashizha eti.Kugadzirisa matambudziko akadaro, shading packaging tekinoroji inogona kushandiswa.
Gasi chipingamupinyi
Kunhuhwirira kwemashizha etii kunorasika nyore, uye zvinhu zvine mhepo inotsiga zvinofanirwa kushandiswa kunhuhwirira-kuchengetedza kurongedza.Mukuwedzera, mashizha etii ari nyore kwazvo kutora kunhuhwirira kwekunze, kuitira kuti kunhuhwirira kwemashizha eti utachiona.Naizvozvo, kunhuhwirira kunogadzirwa nemidziyo yekurongedza uye yekurongedza tekinoroji inofanira kunyatsodzorwa.
Kupisa kwepamusoro
Kuwedzera kwekushisa kunomhanyisa kuita kweiyo oxidation yemashizha etii, uye panguva imwechete inozokonzeresa kupenya kwemashizha etii.Nokudaro, mashizha etii akakodzera kuchengetwa pakupisa kwakadzika.
Composite film bag packaging
Parizvino, kuwedzera uye kuwanda kwekurongedza tii mumusika kwakaiswa mukaticomposite mafirimu mabhegi.Kune akawanda marudzi emafirimu akaumbwa ekurongedza tii, senge mwando-proof cellophane/polyethylene/bepa/aluminium foil/polyethylene, biaxially oriented polypropylene/aluminium foil/polyethylene, polyethylene/polyvinylidene chloride/polyethylene It has excellent barriers, etc. zvivakwa, hunyoro kuramba, kuchengetedza hwema, uye anti-peculiar hwema.Kuita kwefirimu rinosanganiswa nealuminium foil yakanyanya kukwirira, seyakanakisa shading uye zvichingodaro.Kune akasiyana mafomu ekurongedza emabhegi emufirimu akasanganiswa, anosanganisira matatu-mativi chisimbiso,zvikwama zvekumira,zvikwama zvekumira zvine hwindo rakajekauye kupeta.Uye zvakare, iyo composite bhagi bhagi ine yakanaka kudhinda, uye ichava neyakasiyana mhedzisiro kana ichishandiswa pakutengesa kurongedza dhizaini.
