Iqela elivela kwi IYunivesithi yePoltechnic yaseMadrid uyile indlela esebenzisa amagqabi okuthena umthi womnquma ukufumana i-antioxidants yendalo enexabiso eliphezulu lorhwebo. Isindululo sisekelwe kwi izinyibilikisi eziluhlaza kwaye ijonge ukunika ubomi besibini kwimveliso yenkunkuma yezolimo eninzi kweli lizwe.
Uphando, olukhokelwa yi Isikolo sobuGcisa esiPhezulu soShishino lweeNjineli (ETSII), ibonisa ukuba kunokwenzeka ukutshintsha izinyibilikisi eziqhelekileyo, eziphuma kwi-petroleum, kunye neendlela ezikhuselekileyo nezisebenzayo, ngaphandle kokulahlekelwa ukusebenza ukukhutshwa kwe-polyphenol ngexabiso lezinto zokuthambisa, ukutya kunye nekhemesti.
Inkqubo "eluhlaza" yokukhupha i-antioxidants kumagqabi omnquma
Isitshixo kwinkqubela phambili kusetyenziso lwe izinyibilikisi ze-supramolecular, imixube enezigaba ezibini (i-aqueous kunye ne-organic) isakhiwo sayo sinokuhlengahlengiswa ukuphucula ukutsalwa kwi-biomass. Oku kuguquguquka kuvumela ukubuyiswa okuphuculweyo kweekhompawundi ezinovakalelo ezifana polyphenols.
Emva kokuvavanya amayeza ahlukeneyo, iqela lichonge indibaniselwano caprylic acid, ethanol kunye namanziNgale nto, iprotocol yokukhutshwa yacocwa kwaye iimeko zokugcina zaphononongwa ukuze kugcinwe uzinzo lwe-antioxidants ngokuhamba kwexesha.
Le ndlela inciphisa kakhulu ubuthi kunye nefuthe lokusingqongileyo ehambelana nokusetyenziswa kwezinyibilikisi zefosili, kwaye ilungelelaniswe nemigangatho yangoku yokuzinza efunwa lushishino kunye nemigaqo yaseYurophu.
Ukusuka kwinkunkuma yezolimo ukuya kwimithombo enexabiso: impembelelo kunye nokusetyenziswa
ISpain, egxile kuyo yonke indawo I-35% yemveliso yehlabathi zomnquma kunye ngeenxa zonke I-25% yendawo elinywayo, ivelisa izixa ezikhulu zamagqabi kwiphulo ngalinye lokuthena. Uninzi lwezi zinto zitshiswa, ngelixa le ndlela ivula umnyango ukwenza imali ngeemveliso ngokuyiguqula ibe izithako ze-bioactive. Ukuba ufuna ukufunda ngakumbi malunga nokhathalelo kunye ukhathalelo lomthi womnquma kwi bonsai, siyakumema ukuba undwendwele inqaku lethu.
Iipolyphenols ezifunyenweyo ube nomdla kwi izinto zokuthambisa, ukutya kunye nekhemesti ngenxa yomthamo wayo we-antioxidant kunye neprofayili yendalo. Esi siphumo siyahambelana ne i-bioeconomy ejikelezayo, ukudala imizila emitsha yoshishino kwiikopolotyeni kunye nee-oyile ngaphandle kokuguqula umjikelo wokuveliswa kweoli.
- Ukhathalelo lomntu: ukuchasana nokuguga kunye nokukhuselwa kwi-radicals yamahhala.
- Ukutya: ukutyetyiswa kweemveliso ezineekhompawundi ezisebenzayo.
- Ikhemesti/Ikhemistri eNgcono: izithako ezisekelwe kwizityalo ezinexabiso eliphezulu elongezelelweyo.
Kwintsimi, oku kuqinisekiswa kuyanceda ukunciphisa inkcitho kunye nokuphucula uzinzo lwemithi yomnquma ngokukhuthaza ulawulo lokuthena olunoxanduva ngakumbi kunye nokunceda ukunciphisa ukukhutshwa kwenkunkuma okunxulumene nokutshiswa kobutyobo bezityalo. Ukufumana iinkcukacha ezithe vetshe kwi ukusetyenziswa kwe-solvents eluhlaza ekutheneni komnquma.
Ukuqinisekiswa kwezenzululwazi, inkxaso-mali kunye namanyathelo alandelayo
Iziphumo zipapashwe kwijenali I-ACS yeKhemistri eZinzileyo kunye nobuNjineli, ngobungqina bomphandi UAndrea Sanchez ukuqaqambisa ukubanakho kokutshintsha izinyibilikisi eziqhelekileyo kunye nezinye iindlela ze-supramolecular kwesi sicelo.
Umsebenzi uxhaswa yi European Union kunye noLuntu lwaseMadrid ngeeprojekthi I-PID2022-141965OB-C22 y PEJ-2021-AI/AMB-21861, ukongeza kwinkxaso ye Inkqubo eGqwesileyo yeeNjingalwazi zeYunivesithi, eququzelela ukuhanjiswa kweteknoloji ngaphaya kwebhubhoratri.
Abaphandi sele benza inkqubela kwi ukuqinisekiswa komgangatho woshishino kwaye bafunda ukwandisa indlela yokusebenza kwezinye izityalo (ezifana neealmondi kunye neediliya), ngenjongo yokwandisa impembelelo yezoqoqosho kunye nokusingqongileyo kwimimandla eyahlukeneyo yezolimo. Ukuze ufunde ngakumbi malunga Ukwenziwa ngokutsha kunye nokuzinza kumthi womnquma.
Kwicandelo lomnquma, ukwamkelwa kweenkqubo ezinje kunokutolika ingeniso entsha kunye netsheyini yexabiso eyomelela ngakumbi, ngelixa kuncitshiswa ukuxhomekeka iifosili kwiinkqubo zeekhemikhali.
Le ndlela yokusebenza ikhuthaza inguqu ebhekiselele kuqoqosho olujikelezayo noluzinzileyo ngakumbi kwicandelo lezolimo, ukudala amathuba ezoqoqosho kunye nokukhusela okusingqongileyo.
