Carrageenan - ntoni na? Yiyiphi ingozi wenza somfanekiso carrageenan

kwezithako Food (ekwenzeni) ngokubanzi ezisetyenziswa yobisi, confectionery, inyama, ishishini yokubhaka lo. Enkosi ukusebenzisa kwabo imveliso ukuma olufunayo, ukuguda noburhabaxa kwakunye guquki. Kutshanje, e Isetyenziswa ngokubanzi carrageenan somfanekiso. Yintoni na? Kweli nqaku siza kujongana nale mba.

Carrageenan ifunyenwe ngenxa processing of ulwelwe obomvu Rhodophyceae usapho zaselwandle. Ezi ulwelwe ezilinywa phantse onke amanzi komhlaba. ulwelwe Red - izityalo ubushushu-bothando, ukuze, njengokuba umthetho, ingabonwa kunxweme Indonesia, France, Chile, USA ne Canada.

Kungako carrageenan - yiarhente gelling yendalo, thickener. Le besitya lisetyenziswa kwi ezivelisa imveliso zobisi, confectionery, isoseji kunye neemveliso zentlanzi. Ngaphandle carrageenan lugqityiwe kunye nokuveliswa ice cream, kuba ngenxa guquki yayo bukhrim ifunyanwa yi ukusetyenziswa imveliso yokugqibela.

Carrageenan: Ubume

Carrageenan yavulwa kweli kwenkulungwane ye-19, kodwa kude kube ngoku le nto njenge uphando kunye nomdla practical ukuba izazinzulu ezininzi ehlabathini. Amashishini yokuqala nkqubo woshishino carrageenan yabonakala eUnited States kwiminyaka yoo imi--30 lwekhulu XX. Okwangoku, kukho ezingaphezu kwama-3 amawaka iintlobo carrageenan, yaye oku hayi nani lokugqibela. ngonyaka ngamnye, abaphandi bafumanisa iindidi ezintsha carrageenan. Ukususela ngoku, uyazi, xa kwavulwa carrageenan, yintoni na, kwaye uya kusetyenziswa Ziziphi iinkalo kuyo.

Xa niqokelela Isigaba zebhayoloji ukukhula, kwakunye ubunzulu kunye kwiimfuno lisiza ebomvu kuchaphazela iipropati physico-chemical carrageenan. Ngenxa processing uzobe olwenziwe ulwelwe ifunyenwe carrageenans iincindi eziliqela, eziya kwahluka kumafa yemizimba yethu, kwakunye neminye imiqondiso esemgangathweni. Ngeli xesha, kukho amathathu iiklasi carrageenan, ezahlukeneyo okukwiqondo of sulphation: kappa, isuntsu kunye carrageenans Lambda.

Kappa-carrageenan, Yintoni na le nto?

Olu udidi lwe carrageenans olufaneleyo enyibilikayo emanzini ashushu. Emva kokuphela kunye ukupholisa kamva, zakha gel ngamandla high ijeli. Za- iklasi kappa yantle basabela kakuhle kunye neeproteni ubisi. Ngexesha nokuveliswa kwemveliso zenyama njenge additive ukutya esetyenziswa yi kappa-carrageenan. Ukusetyenziswa kweziyobisi ngenxa ukukwazi ukwandisa le viscosity olwelo kunye mayisebenze thickener, hayi nje kuphela, kodwa i emulsifier.

iintlobo carrageenan

Ngu iqondo ucoco carrageenans enokufakwa phantsi kodidi semi-ocacile buphuculwe. Isiphumo lokuqala ifunyenwe abilayo Ingca yolwandle kwi isisombululo obrak. Emva koko, le ziikristale luhluzwa carrageenans, kanzulu kwaye lisuswe isisombululo. Le ndlela ixesha elide kwaye zibiza imali kunokuba. Eyona wayedla kwishishini semi-lisulungekile carrageenan. Olu hlobo ulwelwe ifunyenwe ngokuxuba nesisombululo potassium hayidroksayidi. Potassium kuthintela haydrolisis of carrageenan kwi yesisombululo, kodwa ivumela ukunyibilika iicarbohydrate kunye neeproteni lisiza. Emva ukuphululwa data yesisombululo Ingca yolwandle isusiwe yageza, woma.

Umthambo, yaye Lambda-carrageenan, Yintoni na le nto?

Umthambo-carrageenan Iifomu ijeli siethe kuthelekiswa kappa-gel. Kubalulekile ukuphawula ukuba babe- ezinjalo elastic ngakumbi, baye bakwazi ukubuyisela isakhiwo yayo yokuqala emva kokuba nefuthe ngoomatshini. Kulo mba, umthambo-carrageenan luqhele ukusetyenziswa njenge somfanekiso zokumiswa. Ngaphandle jellies uchazwe apha ngasentla izinzile ngokwaneleyo xa imijikelo olulandelelanayo yovalo / thawing.

Lambda-carrageenan aluyiyo gel kuba liquka inani elikhulu sulfo-maqela, kodwa izisombululo babe eliphezulu viscosity. Ngoko ke, le nxalenye ilungele ukuyilwa emulsions, amagwebu kunye ukumiswa.

Ukusetyenziswa carrageenan additive ukutya

Kukho ulwazi ukuba carrageenan somfanekiso ukutya kukhuselekile kwimpilo yethu, ukongeza, asinto ibe inani iipropati unique siyingenelo. Iingcali abaninzi banoluvo lokuba kuyizuza usebenzisa iziyobisi - ohlambululayo umzimba womntu evela ukungcola oyityhefu imichiza biosoedineny, kuquka enzima. Ukongeza, kufunyaniswe ukuba carrageenans na ialeji ukubonisa antiviral, anticoagulant, anti-bacteria kunye anti-ityhefu isiphumo.

Carrageenan: umonakalo

izazinzulu US ziye zabonisa ukuba carrageenan enomgangatho engabangela uphuhliso izifo phecana zesisu, kwakunye nomhlaza. Yintoni carrageenan kuyingozi? Oku kulimaza additive ukuze edibene into yokuba kukho into eziphilayo esebenzayo nimqumbise uphuhliso reactions ukudumba emzimbeni. Carrageenan ngexesha haydrolisis esiswini ukhupha izinto eziyityhefu, ezo isiseko abangaphezu kwekhulu izifo. Phakathi kwabo, gastritis, enteritis, ukudumba, samathambo, yegazi, njalo njalo. D. neloqheliselo carrageenan kuyingozi kwimpilo yethu, ngoko ngokuqhelekileyo engafakwanga esidlweni.

Kutshanje, abameli WHO licebisa ngamandla ukusetyenziswa kwezithako kwi iimveliso, eyenzelwe ukuba ukutya kwabantwana kunye nabasetyhini abakhulelweyo. Izifundo zakutsha nje yolwazi izazinzulu American lwenziwa kwizilwanyana laboratory zibonise ukuba poliginan (inxalenye iimolekyuli carrageenan) kunokubangela izilonda kunye nomhlaza lokugaya. uthe somfanekiso ukutya ngokwesiseko idatha eyafunyanwa akukho bawela udidi izongezo zokutya akuvumelekanga, kodwa unobangela ezimbi ezininzi ungakwazi ukukhonza, ngoko badle ukudla okune carrageenan (additive ukutya E-407 kunye E-407a) kufuneka ibe ngononophelo. Nangona ubuthi olungqiniweyo, somfanekiso E-407 uvumelekile ukuba asebenzise kummandla uninzi ithi, kuquka i-Russian Federation. Nangona kunjalo, lo ukhetho ngowakho, abahlobo bam.
