Ngenxa yayo “ukusetyenzwa ngokutsha kwezixhobo” uphawu, Ifoyile yealuminiyam esetyenzisiweyo isetyenziswa ngakumbi kwipakethe ye-aseptic yokutya-ingakumbi kwi-croissants kunye nempahla ebhakiweyo.. Ngaphakathi 2024, le mathiriyeli isetyenzisiweyo ibalwe 38% kwimarike yehlabathi ye-aseptic croissant yokupakisha ifoyile yealuminium (umthombo: Iziko leAluminiyam yeHlabathi).

Imathiriyeli yayo ekrwada ubukhulu becala ivela kwiibhetshi zenkunkuma zale nto ikhethekileyo ifoyile yealuminiyam. Ukugcinwa kwe-aseptic croissant, ifoyile ifuna umthwalo ophantsi kakhulu wemicrobial (≤1 CFU/cm²).

Nangona kunjalo, ngexesha lokurisayikilishwa, ifoyile ifunxa lula ioli yecroissant. Le oli ngumxube onzima: “iiasidi ezinamafutha (acid palmitic, 35%-45%), unsaturated fatty acids (oleic acid, 25%-30%), kunye ne-emulsifiers (monoglycerides, 0.5%-2%)”.

Ngokukodwa, uphando kushishino lutyhila ukuba malunga 22% yamashishini avelisa olu mzabalazo wefoyile esetyenzisiweyo kunye nentsalela ye-oyile yecroissant egqithisileyo (>50mg / m²). Oku kugqitha kakhulu kumda we-10mg/m² wefoyile yealuminiyam eseptic croissant yokupakisha..

Intsalela engaphezulu ihlala isuka kwimilinganiselo yokucoca engafanelekanga-efana nokungonelanga koxinzelelo lwealkali okanye ixesha elifutshane kakhulu lokucoca..

Iintsalela ezinjalo azigcini nje ukunciphisa ukucoceka kwezinto ezisetyenzisiweyo kodwa ziphinde zonakalise “isithintelo se-aseptic”. Oku kusongela ukhuseleko lokupakisha lwe-croissant olulandelayo “ungcoliseko lokufuduka” kwaye “ukukhula kwemicrobial”. Uhlalutyo olunzulu ngokwembono yesayensi yezinto zokupakisha ze-aseptic luyimfuneko.

I-Eco-B. Iimpawu zeNgxelo ye-oyile ye-Croissant kunye neNdlela yeNtsalela yayo kwiFoil eRecycled

I-Aseptic croissant yokupakisha ifoyile yealuminiyam kufuneka yanelise zombini “ipropati yomqobo” kwaye “ipropati ye-aseptic”. Iintsalela zeoyile yeCroissant zichanaba ngokuthe ngqo ezi mpawu zimbini, kwaye indlela eyintsalela yayo yohluka kuleyo yefoyile eqhelekileyo yealuminiyam.

(A) Amacandelo angundoqo kunye neePropati zePhysicochemical ze-Oli yeCroissant (Ukufaneleka kwiPakethe ye-Aseptic)

Icandelo leCandelo	Into emeleyo	Uluhlu lomxholo	Iimpawu eziphambili zePhysicochemical	Ukufaneleka kwi-Aseptic Packaging Foil

I-Unsaturated Fatty Acids	I-Oleic Acid, I-Linoleic Acid	25%-30%	Iqulethe iibhondi ezimbini, kulula ukuba oxidize zibe aldehydes kunye acids	Iimveliso ze-oxidation zinokusabela kunye ne-foil passivation layer, ipropathi yomqobo eyonakalisayo
Emulsifiers	Iimonoglycerides, Sucrose Esters	0.5%-2%	I-adsorbs ngokulula kwiindawo zetsimbi, ukwandisa ukunamathela kweoli	Yenza ioli ibenzima ukuyicoca, ukwandisa umngcipheko wokukhula kwe-microbial kwipakethe ye-aseptic
Ii-Antioxidants	BHA, TBHQ	50-100mg / kg	Iqulethe ulwakhiwo lweringi yebenzene, umngcipheko wokufuduka onokwenzeka	Ukufudukela kwi-croissants kuphula iimfuno zokhuseleko lokutya kwipakethe ye-aseptic

Icandelo ngalinye kwi-oyile ye-croissant lidlala indima ekubhengezeni imiba yentsalela. Umzekelo, ii-emulsifiers zomeleza i-oyile-foil bonding, ngelixa i-antioxidants izisa umngcipheko wokufuduka.

(B) Indlela yeNtsalela ye-oyile ye-Croissant kwi-Recycled Aseptic Foil

Emva kokutyumza, ukunyibilika, kunye nokuqengqeleka, imathiriyeli ekrwada (inkunkuma aseptic croissant ukupakisha ifoyile aluminiyam) ibonisa a “i-adsorption yomaleko kabini” iphethini yentsalela yeoli.

Ngqo, intsalela ye-micropore adsorption ibeka umngcipheko okhethekileyo wokupakishwa kwe-aseptic. Ukomeleza ukusebenza komqobo, le foil ekhethekileyo ye-aluminiyam yenza isakhiwo esixineneyo se-microporous (pore ubukhulu 0.1-0.5μm) Ngexesha lokuntywila.

Iimolekyuli ezincinci ze-croissant yeoli (I-E.G., i-methyl palmitate, 0.5-0.8nm ububanzi) ukungena kule pores, ukwenza i “ifilimu yeoli ye-intra-pore”.

Imifuniselo ye-nitrogen adsorption (BET) bonisa ukuba i-oyile eshiyekileyo inciphisa indawo ethile yefoyile ukusuka kwi-1.2m²/g ukuya kwi-0.8m²/g.. Oku kuthintela i-pores kunye nesantya sokuhanjiswa kwe-oksijini kathathu, ukuphelisa umsebenzi wokuthintela ukupakishwa kwe-aseptic.

Ukongeza, intsalela yekhemikhali adsorption yonakalisa umqobo we-aseptic. I-Oleic acid kwi-oyile yecroissant iphendula kunye ne-Al₂O₃ kumphezulu wefoyile ukwenza i-aluminium oleate. (Al(C₁₈H₃₂O₂)₃).

X-reyi Photoelectron Spectroscopy (XPS) iqinisekisa ukuba amandla okubopha i-Al 2p kwiindawo ezishiyekileyo zisuka kwi-74.5eV ukuya kwi-73.8eV-ubungqina bokubambisana kweekhemikhali..

Le oli ebotshelelwe kwiikhemikhali ixhathisa ukuhlamba amanzi okuqhelekileyo. Kwakhona yenza a “umaleko wezondlo” kumphezulu wefoyile, ukudala iimeko zokukhula kwe-microbial kunye nokunciphisa ngokuthe ngqo imeko ye-aseptic yezinto zokupakisha.

I-eco-c. Indlela yeNtsalela yeOli yeCroissant eNciphisa ubunyulu beFoil yeAseptic eRecycled

I-Aseptic croissant yokupakisha ifoyile yealuminiyam ineemfuno ezingqongqo zokucoceka kunefoyile eqhelekileyo: ≥99.5% kwibakala lokutya kunye ≥99.7% kwibakala le-aseptic. Iintsalela ze-oyile zincinci ukucoceka ngeendlela ezimbini eziphambili: “ungcoliseko lwecandelo” kwaye “umonakalo wesakhiwo”.

(A) UkuNcitshiswa kweMichiza yoBunyulu obuBangelwe kukuNgeniswa koKungacoceki kwangaphandle

Kwelinye icala, ukutyebisa carbon yonakalisa uzinzo lwe-aseptic. Palmitic acid (C₁₆H₃₂O₂) kwioli i-carbonizes ngexesha lokufudumeza (120-150℃), ukuvelisa ikhabhoni yasimahla.

Uvavanyo lwe-Carbon-sulphur analyzer lubonisa ukuba kwifoyile ephinda isetyenziswe nge-50mg/m² intsalela., umxholo wekhabhoni womphezulu unyuka ukusuka 0.05% ukuya 0.25%. Oku kugqitha 0.1% umda kwibakala aseptic.

Kwi-100mg/m² intsalela, ikhabhoni isasaza i-0.5-1μm kwi-foil. Oku kwehlisa ubunyulu ukusuka 99.7% ukuya 99.4%, ukusilela ukuhlangabezana ne-GB/T 25198 Iipleyiti zeAluminiyam kunye ne-Aluminiyam ye-Aluminiyam ye-Pressure Vessels imigangatho yokupakishwa kwe-aseptic.

Kwelinye icala, ioksijini eninzi yonakalisa umaleko womqobo. Amaqela e-Hydroxyl kunye ne-carboxyl kwioyile asabela nge-Al₂O₃, ukuqinisa umaleko we-oxide ukusuka kwi-5-10nm ukuya kwi-15-20nm.

Idatha ye-oxygen-nitrogen analyser ibonisa umxholo we-oksijini ukwanda ukusuka 0.12% ukuya 0.35%. Oku kunciphisa i-foil's ductility-elongation iwa 15% ukuya 10%.

Ukuqhekeka kwakheka ngexesha lokubunjwa kwefoyile, ukutshabalalisa umqobo we-aseptic.

(B) UkuNcitshiswa koBunyulu boMzimba okubangelwa ngumonakalo weMicrostructural

Ifoyile yokupakisha i-aseptic ixhomekeke kwi-microstructure efanayo ukugcina ubunyumba-into eshiyekileyo yeoli iyaphazamisa..

Umzekelo, i-monoglycerides kwi-oyile adsorb kwimida yeenkozo ngexesha lokuxilisa (300-350℃). Oku kuthintela ukukhula kweenkozo.

Ukuqwalaselwa kwe-metallographic kubonisa ukuba i-foil eqhelekileyo ine-20-30μm ubukhulu beenkozo ezihambelanayo. I-foil engcolisekileyo yentsalela, ngokuphikisana, ibonisa ukungalingani 5-40μm iinkozo.

Iindawo eziziinkozo ziqokelela ngokulula ii-microorganisms, okukhokelela ekuvaleni inzala okungaphelelanga.

Ngaphezulu, ikhabhoni yasimahla kwi-oyile ye-carbonization iqokelela kwimida yengqolowa. Oku kwenza umaleko otyebileyo wekhabhoni oyi-0.2-0.5μm (ijongwe nge-TEM).

Ngokufikelela kumxholo wekhabhoni womda wengqolowa 0.5%-1.0%, izinga lokuqhekeka kwe-foil ye-intergranular ngexesha lokunyathela liyenyuka ukusuka 3% ukuya 15%. Oku kuthintela ukubunjwa kwesakhiwo sokupakisha se-aseptic esipheleleyo.

I-Eco-D. Izoyikiso eziManinzi eziDimensional zeCroissant oil Residue kuKhuseleko lokuPakisha lweAseptic Croissant

Ngaphaya kwemiba yobunyulu, iintsalela zeoyile zibeka imingcipheko eqatha kwiinjongo eziphambili zokupakishwa kwe-aseptic croissant: “ukugcina imeko ye-aseptic” kwaye “ukuqinisekisa ukhuseleko lokutya”. Ezi zoyikiso zibonakala ngeendlela ezintathu eziphambili.

(A) Ukusilela kweAseptic Barrier (Eyohlukileyo kwiPakethe yeAseptic)

I-foil ifezekisa ukugcinwa kwe-aseptic ngokusebenzisa “umqobo womzimba + ubunyulu bomphezulu”, kwaye iintsalela zonakalisa zombini.

Ekuqaleni, ukukhula kwemicrobial kophula inzala. Ifoyile ene-50mg/m² intsalela yeoyile, igcinwe kwi-25 ℃ kwaye 70% ukufuma kwe 7 iintsuku, ibonisa i-10² CFU/cm² ye-Escherichia coli. Oku kugqitha kude ≤1 CFU/cm² umgangatho weaseptic.

Xa isetyenziselwa ukupakisha i-croissant, iimicroorganisms ziphindaphindeka ngokukhawuleza. Oku konyusa amazinga okuhla ukusuka 0.1% ukuya 8% kubomi beshelufu obuqhelekileyo beentsuku ezisi-7.

Isibini, ukunciphisa ukungena kwe-sterilization iyawenza mandundu umcimbi. Ifilimu yeoli ivimba i-foil surface, ukusika ukungena kwe-ultraviolet sterilization (inkqubo yokupakisha aseptic eqhelekileyo) ukusuka 90% ukuya 50%.

Iindawo ezingahlambulukanga zibonisa 20% intsalela yemicrobial. Oku kwaphula i-GB/T 31402 Umda weMicrobial wezinto zokuPakisha kunye neeMveliso.

(B) Imingcipheko yokuFuduka koKutya (Yenziwa mandundu kwiiSetingi ze-Aseptic)

Iintsalela ze-oyile zibangela ukuba izinto ezinobungozi zifudukele kwi-croissants.

Njengokuba, i-oleic acid i-oxidizes kwi-malondialdehyde ngexesha lokugcinwa. Izixa-mali zokufuduka zifikelela kwi-0.3-0.8mg/dm²—zigqithise kumda we-0.5mg/dm² kwi-GB 31604.1.

I-Malondialdehyde isabela kunye ne-croissant proteins, ukubeka esichengeni ukhuseleko lokutya.

Ngokukodwa, Umaleko we-foil owonakalisiweyo wokudlula ukhokelela ukukhutshwa ngokugqithisileyo kwe-aluminium. Le yinkxalabo enkulu yokupakishwa kwe-aseptic ngenxa yoqhagamshelwano lokutya ixesha elide.

Kwi-croissants ene-acidic (I-E.G., abo banelamuni), I-aluminium leaching ibetha i-0.2mg/dm². Oku kuphinda kabini umda we-0.1mg/dm² kwi-GB 4806.3, kubeka imingcipheko yempilo yexesha elide.

(C) Ukupakisha Ukonakala Kwemfezeko (Ukunciphisa uBomi beShelufu ye-Aseptic)

Ukupakishwa kweAseptic kufuna umqobo opheleleyo, kodwa iintsalela zeoyile zikhawulezisa ukubola kwefoyile.

Uvavanyo lwendawo yokusebenzela ye-Electrochemical ibonisa i-foil engcoliswe yintsalela inoxinzelelo lwangoku lokutya kwe-1.5×10⁻⁶ A/cm². Oku kuphindwe kathathu kune-foil ecocekileyo.

Ifoyile etyebileyo eyi-0.01mm igqobhoza ngaphakathi 6 iinyanga. Oku kunciphisa ubomi beshelufu e-croissant ukusuka 7 iintsuku ukuya 3 iintsuku.

Ngokuphikisana, Cl⁻ kwioli (ukusuka kwityuwa ye-croissant) kunye neeasidi ezinamafutha zenza imingxuma (1-5μm ubukhulu, ijongwe nge-SEM).

Oku konyusa izinga lokuhanjiswa kweoksijini ukusuka kwi-1cm³/(M² · A · w · w · w · w · w² · wh · wh · wh · whyp) ukuya kwi-5cm³/(M² · A · w · w · w · w · w² · wh · wh · wh · whyp). Ukuwohloka kweCroissant oxidation kunyuka 40%.
