Raws li tshuaj yej yog cov nroj tsuag ntuj, qee yam ntawm nws cov khoom ntuj tsim ua rau kev ntim tshuaj yej nruj.
Yog li ntawd, lub ntim tshuaj yej muaj qhov yuav tsum tau muaj los tiv thaiv oxidation, noo noo-pov thawj, kub tsis kam, shading thiab roj kuj.
Antioxidation
Cov ntsiab lus oxygen ntau dhau hauv pob yuav ua rau oxidative deterioration ntawm qee yam khoom hauv tshuaj yej. Piv txwv li, lipid tshuaj yuav oxidize nrog oxygen nyob rau hauv qhov chaw los tsim aldehydes thiab ketones, yog li ua rau rancid tsw. Yog li ntawd, cov ntsiab lus oxygen hauv cov tshuaj yej ntim yuav tsum tswj tau zoo hauv qab 1%. Nyob rau hauv cov nqe lus ntawm ntim tshuab, inflatable ntim los yog lub tshuab nqus tsev ntim yuav siv tau los txo cov muaj oxygen. Lub tshuab nqus tsev ntim tshuab yog ib txoj kev ntim khoom uas tso cov tshuaj yej rau hauv lub hnab ntim zaj duab xis (lossis aluminium foil nqus hnab) nrog cov huab cua zoo, tshem tawm cov huab cua hauv lub hnab thaum lub sijhawm ntim, tsim kom muaj qee qhov nqus, thiab tom qab ntawd muab khi; Inflatable ntim tshuab yog los sau cov roj inert xws li nitrogen los yog deoxidizer thaum tso pa tawm, thiaj li tiv thaiv kev ruaj ntseg ntawm cov xim, aroma thiab saj ntawm tshuaj yej thiab tswj nws cov khoom qub.
Kub kub kuj.
Qhov kub thiab txias yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm cov tshuaj yej. Qhov kub sib txawv yog 10 ℃, thiab tus nqi ntawm cov tshuaj tiv thaiv yog 3 ~ 5 npaug sib txawv. Tshuaj yej yuav ua kom cov oxidation ntawm nws cov ntsiab lus nyob rau hauv qhov kub thiab txias, ua rau kom ceev ceev ntawm polyphenols thiab lwm yam zoo tshuaj thiab accelerated zoo deterioration. Raws li kev siv, tshuaj yej cia kub hauv qab 5 ℃ yog qhov zoo tshaj plaws. Thaum qhov kub ntawm 10 ~ 15 ℃, cov xim ntawm cov tshuaj yej yuav poob qis, thiab cov nyhuv xim kuj tuaj yeem tswj tau. Thaum qhov kub siab tshaj 25 ℃, cov xim ntawm cov tshuaj yej yuav hloov sai heev. Yog li ntawd, tshuaj yej yog haum rau preservation ntawm tsawg kub.
noo noo-pov thawj
Cov ntsiab lus dej hauv tshuaj yej yog qhov nruab nrab ntawm kev hloov pauv biochemical hauv tshuaj yej, thiab cov ntsiab lus dej tsawg yog qhov tsim nyog rau kev khaws cov tshuaj yej zoo. Cov ntsiab lus dej hauv cov tshuaj yej yuav tsum tsis pub tshaj 5%, thiab 3% yog qhov zoo tshaj plaws rau kev khaws cia ntev, txwv tsis pub cov ascorbic acid hauv cov tshuaj yej yog yooj yim decompose, thiab xim, aroma, thiab saj ntawm cov tshuaj yej yuav hloov, tshwj xeeb tshaj yog nyob rau ntawm qhov kub thiab txias, qhov deterioration tus nqi yuav nrawm dua. Yog li ntawd, thaum ntim, peb tuaj yeem xaiv cov zaj duab xis sib xyaw nrog cov dej noo-pov thawj zoo, xws li aluminium ntawv ci lossis aluminium foil evaporation zaj duab xis ua cov khoom siv yooj yim rau ntim cov ntaub ntawv noo noo.
ntxoov ntxoo
Lub teeb tuaj yeem txhawb nqa oxidation ntawm chlorophyll, lipid thiab lwm yam tshuaj hauv tshuaj yej, nce tus nqi ntawm glutaraldehyde, propionaldehyde thiab lwm yam tshuaj tsw qab hauv tshuaj yej, thiab ua kom cov tshuaj yej muaj zog. Yog li ntawd, thaum ntim tshuaj yej, lub teeb yuav tsum tau shielded los tiv thaiv cov tshuaj tiv thaiv photocatalytic ntawm chlorophyll, lipid thiab lwm yam khoom. Tsis tas li ntawd, hluav taws xob ultraviolet kuj yog ib qho tseem ceeb ua rau cov tshuaj yej deterioration. Txhawm rau daws qhov teeb meem no, shading ntim tshuab siv tau.
Choke
Lub aroma ntawm tshuaj yej yog yooj yim heev rau dissipate, thiab yog ib qho yooj yim mus rau lub zog ntawm sab nraud tsw, tshwj xeeb tshaj yog cov residual hnyav ntawm composite daim nyias nyias thiab cov ntxhiab decomposed los ntawm tshav kub sealing kev kho mob yuav cuam tshuam cov tsw ntawm tshuaj yej, uas yuav cuam tshuam cov aroma ntawm tshuaj yej. Yog li ntawd, lub ntim tshuaj yej yuav tsum zam kom tsis txhob muaj ntxhiab tsw ntawm lub ntim thiab nqus cov ntxhiab los ntawm sab nraud. Cov khoom ntim tshuaj yej yuav tsum muaj qee yam roj barrier zog.
