Green tei inonyanya kuve nezvikamu zvakadai seascorbic acid, tannins, polpenoliol compounds, mafuta ekatinini uye maCherotoids. Izvi zvinongedzo zvinokanganiswa nekuora kweiyo oksijeni, tembiricha, humidity, mwenje uye njere dzezvakatipoteredza. Naizvozvo, kana tii yekuputika, pesvedzero yezvinyorwa zvevatevedzeri inofanirwa kuve isina simba kana kudzivirira, uye izvo zvinodiwa ndizvo zvinotevera:
Kunyorova kuramba
Iyo yemvura yemvura mu tii haifanirwe kupfuura 5%, uye 3% ndiyo yakanyanya kunaka yekuchengetedza kwenguva refu; Zvikasadaro, iyo ascorbic acid muTidhi ichave iri nyore kurwa, uye ruvara, kunhuhwirira uye kuravira kwetii kuchachinja, kunyanya pakupisa kwakanyanya. , mwero wekuoraya uchakurumidza. Naizvozvo, kurongedza zvinhu zvine chekuita nekunyorova-kwehunhu Kutarisirwa kwakakosha kunofanirwa kubhadharwa kune unyoro-kurapa kwekurapa kwetete nhema tei.
Oxidation kupokana
Iyo okisijeni zvirimo mupakeji inofanira kudzorwa pazasi 1%. Yakawandisa oksijeni ichaita zvimwe zvikamu muTiyeti kune oxIDUTICELY DZVANYANYA. Semuenzaniso, ascorbic acid iri nyore oxidized mu deoxyascorbic acid, uye zvimwe zvinosanganisira neamino acids kuti vasiye pigment maitiro, Sezvo tii netii ine huwandu hwakatemerwa hwemafuta asina kujairika ruvara runosviba.
Shading
Sezvo tii tei tei tei Uye zvakare, ultraviolet riys iri zvakare chakakosha pane kukonzera kushatisa kwemashizha eti. Kugadzirisa matambudziko akadaro, shading packagical tekinoroji inogona kushandiswa.
Chipinganidzo chegesi
Iyo yekunhuhwirira kwetii mashizha anorasika nyore, uye zvigadzirwa zvine mhepo yakanaka-kusimbiswa kunofanirwa kushandiswa kune chinonhuwira-kuchengetedza kurongedza. Mukuwedzera, mashizha etii ari nyore kwazvo kutora mafuta ekunze, zvekuti zvinonhuwira zvetii mashizha akatapukirwa. Naizvozvo, zvinonhuwira zvinogadzirwa nekuzvirongedza zvinhu uye mapepa ekurapa anofanirwa kudzorwa zvakanyanyisa.
Kupisa kwakanyanya
Kuwedzera kwe tembiricha kuchakurumidza kuita oxidation maitiro emashizha emashizha, uye panguva imwechete ichaita kuti nzvimbo yemukati yei yetii yekupera kupera. Naizvozvo, mashizha eti akakodzera kuchengetedza pakudziya kwakaderera.
Composite film bhegi kurongedza
Parizvino, zvimwe uye zvimwe tei tei pakutakura mumusika kurongedzwa mukaticomposite film mabhegi. Kune akawanda marudzi emhando yemifananidzo yemifananidzo yemifananidzo, yakadai seyineti-yehupombwe / Polyethylene / Polythylene / Polythylidene chloride chloride chloride chloride chloride chloride chloride chloride chloride chloride chloride chloride chloride chloride zvivakwa, kunyorova Kuramba, kunhuhwirira kwechinonhuwira, uye kunhuwa-kwezvinhu zvekunhuhwirira. Iko kuita kweiyo kirimu yemhando nealuminium foil ndiyo yakanyanya kunaka, yakadai seyakawedzera shadding uye zvichingodaro. Kune akasiyana marongero emhando dzemhando dzemabhegi emapikicha, kusanganisira kuiswa-matatu-matatu kuiswa chisimba,mira-up pouches,mira-up pouches newindo rakajekauye kupeta. Uye zvakare, iyo composite firimu bhegi ine yakanaka yekudhinda, uye ichave nemhedzisiro yakasarudzika kana ichishandiswa pakutengesa kurongedza dhizaini.
