Njengoko iti sisityalo sendalo, ezinye zeempawu zayo zendalo zikhokelela ekupakishweni okungqongqo kweti.
Ke ngoko, ukupakishwa kweti kuneemfuno ze-anti oxidation, ubungqina bokufuma, ukumelana nobushushu obuphezulu, shading kunye nokumelana negesi.
I-Anti oxidation
Umxholo we-oksijini ogqithiseleyo kwi-package uya kubangela ukuwohloka kwe-oxidative yamacandelo athile kwiti. Ngokomzekelo, izinto ze-lipid ziya ku-oxidize nge-oksijini esithubeni ukuvelisa i-aldehydes kunye ne-ketones, ngaloo ndlela kuvelisa i-rancid ivumba. Ngoko ke, umxholo we-oxygen kwipakethe yeti kufuneka ulawulwe ngokufanelekileyo ngaphantsi kwe-1%. Ngokuphathelele iteknoloji yokupakisha, ukupakishwa kwe-inflatable okanye ukupakishwa kwe-vacuum kungasetyenziselwa ukunciphisa ubukho be-oksijini. Itekhnoloji yokupakisha i-vacuum yindlela yokupakisha ebeka itiye kwi-soft film packaging bag (okanye i-aluminium foil vacuum bag) enomoya omhle, isuse umoya engxoweni ngexesha lokupakisha, idale iqondo elithile le-vacuum, kwaye emva koko uyitywine; Itekhnoloji yokupakishwa kwe-inflatable kukugcwalisa iigesi ze-inert ezifana ne-nitrogen okanye i-deoxidizer ngelixa ukhupha umoya, ukwenzela ukukhusela ukuzinza kombala, iphunga kunye nencasa yeti kunye nokugcina umgangatho wayo wokuqala.
Ukumelana nobushushu obuphezulu.
Ubushushu yinto ebalulekileyo echaphazela umgangatho weti. Umahluko weqondo lobushushu yi-10 ℃, kwaye isantya sokusabela kweekhemikhali si-3 ~ 5 ngamaxesha ahlukeneyo. Iti iya kuqinisa i-oxidation yeziqulatho zayo phantsi kobushushu obuphezulu, okukhokelela ekunciphiseni ngokukhawuleza kwe-polyphenols kunye nezinye izinto ezisebenzayo kunye nokuwohloka komgangatho okhawulezileyo. Ngokutsho kokuphunyezwa, ubushushu bokugcina iti bungaphantsi kwe-5 ℃ yeyona nto ingcono. Xa ubushushu buyi-10 ~ 15 ℃, umbala weti uya kuhla kancinci, kwaye umphumo wombala ungagcinwa. Xa ubushushu budlula 25 ℃, umbala weti uya kutshintsha ngokukhawuleza. Ngoko ke, itiye ifanelekile ukugcinwa kumaqondo aphantsi.
Ubungqina bokufuma
Isiqulatho samanzi kwiti siphakathi kotshintsho lwebhayoloji kwiti, kwaye umthamo wamanzi asezantsi ulungele ukugcinwa komgangatho weti. Umxholo wamanzi kwi-tea akufanele udlule i-5%, kwaye i-3% iyona nto ibhetele yokugcina ixesha elide, ngaphandle koko i-ascorbic acid kwi-tea ilula ukubola, kwaye umbala, iphunga, kunye nencasa yeti iya kutshintsha, ngakumbi kwiqondo lobushushu eliphezulu, izinga lokuwohloka liya kukhawuleziswa. Ngoko ke, xa sipakisha, sinokukhetha ifilimu edibeneyo kunye nokusebenza kakuhle kobungqina bokufuma, njenge-aluminium foil okanye ifilimu ye-aluminiyam ye-evaporation film njengeyona nto isisiseko yokupakishwa kobumanzi.
ukwenza umbala
Ukukhanya kunokukhuthaza i-oxidation ye-chlorophyll, i-lipid kunye nezinye izinto kwiti, ukwandisa inani le-glutaraldehyde, i-propionaldehyde kunye nezinye izinto ezivumbayo kwiti, kunye nokukhawulezisa ukuguga kweti. Ngoko ke, xa upakisha iti, ukukhanya kufuneka kukhuselwe ukukhusela ukusabela kwe-photocatalytic ye-chlorophyll, i-lipid kunye nezinye izinto. Ukongeza, imitha ye-ultraviolet nayo yinto ebalulekileyo ebangela ukuwohloka kweti. Ukusombulula le ngxaki, iteknoloji yokupakisha shading ingasetyenziswa.
Ukukrwitsha
Iphunga leti lilula kakhulu ukuchithwa, kwaye lisengozini kwimpembelelo yevumba langaphandle, ngokukodwa i-solvent eseleyo ye-membrane edibeneyo kunye nevumba elibolileyo ngonyango lokutywinwa kobushushu liya kuchaphazela incasa yeti, eya kuchaphazela ivumba leti. Ke ngoko, ukupakishwa kweti kufuneka kuthintele ukubaleka ivumba elivela kwipakethe kunye nokufunxa ivumba elingaphandle. Izinto zokupakisha iti kufuneka zibe neempawu ezithile zokuthintela igesi.
