Hangata tee e tala e na le likarolo tse kang ascorbic acid, tannins, polyphenolic compounds, mafura a catechin le carotenoids.Metsoako ena e ka senyeha habonolo ka lebaka la oksijene, mocheso, mongobo, khanya le monko oa tikoloho.Ka hona, ha u paka tee, tšusumetso ea lintlha tse ka holimo e lokela ho fokotsoa kapa e thibeloe, 'me litlhoko tse khethehileng ke tse latelang:
Ho hanyetsa mongobo
Likahare tsa metsi ka tee ha lia lokela ho feta 5%, 'me 3% ke eona e molemo ka ho fetisisa bakeng sa polokelo ea nako e telele;ho seng joalo, asiti ea ascorbic ka tee e tla senyeha habonolo, 'me' mala, monko le tatso ea tee li tla fetoha, haholo-holo ka mocheso o phahameng., lebelo la ho senyeha le tla potlakisa.Ka hona, lisebelisoa tsa ho paka tse nang le ts'ebetso e ntle ea bopaki ba mongobo li ka khethoa bakeng sa liphutheloana tse thibelang mongobo, joalo ka lifilimi tse kopaneng tse thehiloeng holim'a foil ea aluminium kapa filimi ea aluminium e evaporated, e ka bang bopaki bo bongata ba mongobo.Tlhokomelo e khethehileng e lokela ho lefshoa ho phekolo ea bopaki ba mongobo ea liphutheloana tsa tee tse ntšo.
Ho hanyetsa oxidation
Likahare tsa oksijene ka har'a sephutheloana li tlameha ho laoloa ka tlase ho 1%.Oksijene e ngata haholo e tla etsa hore likarolo tse ling tsa tee li senyehe.Ka mohlala, ascorbic acid e habonolo oxidized ka deoxyascorbic acid, 'me ka ho eketsehileng kopana le amino acid ho kena pigment karabelo, e leng etsa hore tatso ea tee mpe le ho feta.Kaha mafura a tee a na le li-unsaturated fatty acids tse ngata, li-unsaturated fatty acids li ka etsoa ka bohona ho hlahisa metsoako ea carbonyl e kang aldehydes le ketone le metsoako ea enol, e ka etsang hore monko oa tee o nyamele, astringency e ba bobebe, 'me mmala o ba lefifi le ho feta.
Shading
Kaha tee e na le chlorophyll le lintho tse ling, ha u paka makhasi a tee, leseli le tlameha ho sireletsoa ho thibela karabelo ea photocatalytic ea chlorophyll le likarolo tse ling.Ho feta moo, mahlaseli a ultraviolet hape ke ntlha ea bohlokoa ho bakang ho senyeha ha makhasi a tee.Ho rarolla mathata a joalo, ho ka sebelisoa theknoloji ea ho kenya shading.
Thibelo ea khase
Monko o monate oa makhasi a tee o lahleha habonolo, 'me lisebelisoa tse nang le ho thibela moea hantle li tlameha ho sebelisoa bakeng sa liphutheloana tse bolokang monko.Ho phaella moo, makhasi a tee a bonolo haholo ho monya monko o ka ntle, e le hore monko oa makhasi a tee a tšoaelitsoe.Ka hona, monko o hlahisoang ke lisebelisoa tsa ho paka le theknoloji ea ho paka o lokela ho laoloa ka thata.
Mocheso o phahameng
Keketseho ea mocheso e tla potlakisa karabelo ea oxidation ea makhasi a tee, 'me ka nako e ts'oanang e tla etsa hore khanya ea makhasi a tee e nyamele.Ka hona, makhasi a tee a loketse ho boloka mocheso o tlase.
Sephutheloana sa mokotla oa filimi o kopantsoeng
Hajoale, liphutheloana tsa tee tse ntseng li eketseha 'marakeng li kentsoe ka har'amekotla e kopantsoeng ea lifilimi.Ho na le mefuta e mengata ea lifilimi tse kopantsoeng bakeng sa ho paka tee, joalo ka cellophane / polyethylene / pampiri / aluminium foil / polyethylene, biaxially oriented polypropylene / aluminium foil / polyethylene, polyethylene / polyvinylidene chloride / polyethylene e na le khase e ntle haholo, joalo-joalo. thepa, ho hanyetsa mongobo, ho boloka monko o monate, le monko o khahlanong le o ikhethang.Ts'ebetso ea filimi e kopantsoeng e nang le foil ea aluminium e phahame haholo, e kang shading e babatsehang joalo-joalo.Ho na le mefuta e fapaneng ea ho paka ea mekotla ea lifilimi e kopantsoeng, ho kenyelletsa le ho tiisa ka mahlakoreng a mararo,mekotlana ya ho ema,mekotlana e emang ka fensetere e hlakilengle ho phutha.Ho phaella moo, mokotla oa filimi o kopantsoeng o na le khatiso e ntle, 'me e tla ba le phello e ikhethang ha e sebelisoa bakeng sa moralo oa liphutheloana tsa thekiso.
