Ukupakishwa kokutya kukwindawo ebalulekileyo kwimveliso nasekujikelezweni kokutya, kodwa ngelixa kuzisa izibonelelo kunye noncedo ebantwini, kukwakho iingxaki zokungcoliseka kwendalo ezibangelwa kukupakishwa kwenkunkuma. Ke, kwiminyaka yakutshanje, ukulungiswa kunye nokusetyenziswa kweefilimu zokupakisha ezidliwayo kuye kwenziwa ekhaya nakwamanye amazwe. Ngokutsho kophando, ifilimu yokupakisha edliwayo ineempawu zokukhuselwa kokusingqongileyo okuluhlaza, ukhuseleko kunye ne-biodegradability. Inokuqinisekisa umgangatho wokutya ngokusebenza kokumelana ne-oxygen, ukuxhathisa ukufuma kunye nokufuduka kwe-solute, ukwenzela ukwandisa ubomi beshelufu yokutya. Ifilimu yokupakisha yangaphakathi etyiwayo yenziwa ikakhulu ngezinto zebhayoloji ze-macromolecular, ezinamandla athile omatshini kunye neoyile ephantsi, ioksijini kunye nokungena kwamanzi, ukuze kuthintelwe ukuvuza kwejusi ye-seasoning okanye i-oyile, kwaye i-seasoning iya kuba manzi kwaye ivundiswe Ukongeza. , inonyibiliko oluthile lwamanzi kwaye ikulungele ukutyiwa. Ngophuhliso olukhawulezayo lweshishini lelizwe lam elilungele ukwenziwa kokutya, ukusetyenziswa kweefilimu ezityiwayo zokupakishwa kwangaphakathi kwiicondiments kuya kwanda ngokuthe ngcembe kwixesha elizayo.
01. I-sodium carboxymethyl cellulose
I-sodium carboxymethyl cellulose (CMC-Na) yi-carboxymethylated derivative ye cellulose kwaye yeyona ibalulekileyo ionic cellulose gum. I-sodium carboxymethyl cellulose idla ngokuba yi-anionic polymer compound elungiselelwe ngokusabela i-cellulose yendalo kunye ne-alkali ye-caustic kunye ne-monochloroacetic acid, enobunzima bemolekyuli ukusuka kumawaka amaninzi ukuya kwizigidi. I-CMC-Na yi-fibrous emhlophe okanye i-granular powder, ayinavumba, ingenancasa, i-hygroscopic, ilula ukusasazeka emanzini ukwenza isisombululo se-colloidal esicacileyo.
I-sodium carboxymethyl cellulose luhlobo lwe-thickener. Ngenxa yeempawu zayo ezilungileyo zokusebenza, isetyenziswe ngokubanzi kwishishini lokutya, kwaye ikwakhuthaze uphuhliso olukhawulezayo nolunempilo lweshishini lokutya ukuya kuthi ga kwinqanaba elithile. Ngokomzekelo, ngenxa yokuqina kwayo kunye ne-emulsifying effect, ingasetyenziselwa ukuzinzisa iziselo ze-yogurt kunye nokwandisa i-viscosity ye-yoghurt system; ngenxa yezinto ezithile ze-hydrophilicity kunye ne-rehydration, ingasetyenziselwa ukuphucula ukusetyenziswa kwe-pasta njengesonka kunye nesonka esiqhumayo. umgangatho, ukwandisa ubomi beshelufu yeemveliso zepasta, kunye nokuphucula incasa; ngenxa yokuba inefuthe elithile le-gel, lilungele ukubunjwa okungcono kwe-gel ekudleni, ngoko ingasetyenziselwa ukwenza i-jelly kunye ne-jam; inokuphinda isetyenziswe njengefilimu etyiwayo yokugquma Izinto eziphathekayo zixutywe kunye nezinye i-thickeners kwaye zifakwe kumphezulu wokutya okunye, okunokugcina ukutya kutsha kwinqanaba elikhulu, kwaye ngenxa yokuba liyinto edliwayo, ayiyi kubangela ukungahambi kakuhle. iziphumo kwimpilo yabantu. Ke ngoko, i-CMC-Na yebakala lokutya, njengesongezo sokutya esifanelekileyo, isetyenziswa kakhulu kwimveliso yokutya kwishishini lokutya.
02. Ifilimu etyiwayo ye-sodium carboxymethylcellulose
I-Carboxymethyl cellulose yi-ether ye-cellulose enokuthi yenze iifilimu ezigqwesileyo ngendlela yeegels ze-thermal, ngoko isetyenziswa ngokubanzi kumashishini amayeza kunye nokutya. Ifilimu yeCarboxymethyl cellulose yioksijini esebenzayo, ikharbon diokside kunye nesithintelo selipid, kodwa ayinakuxhathisa ukuhanjiswa komphunga wamanzi. Iifilimu ezidliwayo zinokuphuculwa ngokufaka izinto ze-hydrophobic, ezifana ne-lipids, kwisisombululo sokwenza ifilimu Ngoko ke, kwaziwa ngokuba yi-lipid derivative.
1. CMC-lotus ingcambu istatshi-tea umthi oyile ifilimu ezityiwayo unokuhlangabezana neemfuno uhlaza, ukhuseleko kunye nongcoliseko-free, nto leyo ayiqinisekisi kuphela umgangatho wokutya kodwa ayinciphisi isiphumo ukupakisha. Kulindeleke ukuba iphuhliswe kwaye isetyenziswe kwi-noodle esheshayo, ikofu esheshayo, i-oatmeal esheshayo kunye ne-soybean milk powder kwixesha elizayo. Ingxowa yokupakisha yangaphakathi ithatha indawo yefilimu yeplastiki yemveli.
2. Ukusebenzisa i-carboxymethyl cellulose njengesiseko sokwenza ifilimu, i-glycerin njenge-plasticizer, kunye nokongeza isitashi se-cassava njengezinto ezincedisayo ukulungisa ifilimu edibeneyo enokutyiwa, ifaneleke ngakumbi ukupakishwa kweviniga kunye neepakethi zomgubo ezigcinwe ngaphakathi kweentsuku ezingama-30 kunye namafutha exesha elide. ifilimu yokusonga.
3. Ukusebenzisa umgubo we-lemon peel, i-glycerin, kunye ne-sodium carboxymethylcellulose njengokwenza ifilimu imathiriyeli ekrwada yeefilimu ezityiwayo zamaxolo elamuni.
4. Ukusebenzisa isisombululo samanzi se-sodium carboxymethyl cellulose njengesithwala kunye ne-nobiletin yebakala lokutya njengento ekrwada, into edibeneyo yokugquma ye-nobiletin-sodium carboxymethyl cellulose yalungiselelwa ukwandisa ubomi beshelufu yeekhukhamba.
