Beta-carotene
Beta-carotene waa carotenoid dabiici ah oo si weyn looga helo khudaarta cagaaran iyo jaalaha ah iyo miraha.Beta-carotene waa xarun tetraterpenoid ah, oo ka kooban afar isoprene double bonds.Waxay leedahay hal giraan oo beta-violon ah oo ku yaal cidhif kasta oo molecule ah.Laba molecule oo fitamiin A ah ayaa la soo saari karaa marka la gooyo bartamaha.Waxa ay leedahay dhawr bonds oo labajibbaaran iyo isku xidhayaal u dhexeeya labada curaarta.Molecules waxay leeyihiin koromophore labajibbaaran oo isku xidhan muddo dheer, markaa waxay leeyihiin hantida nuugista iftiinka waxayna ka dhigaan jaale.Noocyada ugu muhiimsan ee beta-carotene waa all-trans, 9-cis, 13-cis iyo 15-cis.Waxa jira in ka badan 20 isomers oo beta-carotene ah, kuwaas oo aan lagu milmi karin biyaha oo wax yar ku milmay saliidda cuntada.Waxay si dhexdhexaad ah ugu milmaan hydrocarbons aliphatic iyo caraf udgoon, si fudud ugu milmay chloroform, degganaansho la'aan guryaha kiimikada, oo ay fududahay in ay oksaydheeyaan iftiinka iyo kuleylka.
Beta-carotene waxaa lagu soo saari karaa isku-dhafka kiimikada, soo saarista dhirta iyo halsano microbial.Marka loo eego hababka wax-soo-saarka ee kala duwan, waxa loo qaybin karaa laba qaybood: isku-dhafka kiimikada ee beta-carotene iyo beta-carotene ee dabiiciga ah.Waqtigan xaadirka ah, badankood waa kiimiko.Sababtoo ah beta-carotene ee dabiiciga ah waxay leedahay aberration-ka-hortagga koromosoomyada wanaagsan, saamaynta kansarka ka hortagga iyo dhaqdhaqaaqa jireed ee xooggan, qiimaha beta-carotene ee dabiiciga ah ayaa sarreeya.Waxay laba jibaar ka badan tahay kiimikooyinka.
Beta-carotene waxaa loo yaqaanaa isha laga helo fiitamiin A. Beta-carotene oo hore loo farsameeyay ayaa si weyn loogu isticmaali jiray cuntada, qurxinta iyo alaabta caafimaadka.Iyadoo horumarinta toxicology iyo tignoolajiyada falanqaynta, cilmi-baaristu waxay muujinaysaa in inkasta oo nadiifinta beta-carotene ee lagu farsameeyay habka kiimikaad ay aad u sarreyso qiimaha wax soo saarkuna uu yar yahay, way fududahay in lagu daro qadar yar oo kiimikooyinka sunta ah ee alaabta.Sidaa darteed, iyada oo horumarinta joogtada ah ee aqoonta, soo saarista dabiiciga ah ee beta-carotene waxay qaadan doontaa boos firfircoon oo suuqa ah.Laakiin sababta oo ah hantida dufanka-milaysa ee beta-carotene, baaxadda codsigeeda ayaa si weyn loo xaddiday.Daraasadaha qaarkood waxay xoojiyeen milanka biyaha ee beta-carotene by saponification iyo emulsification, laakiin habkani wuxuu leeyahay waqti dheer, wuxuu saameyn weyn ku leeyahay xasilloonida beta-carotene, wuxuuna leeyahay qiime sare.Soo saarista beta-carotene ee dabiiciga ah, dareerayaasha organic ee inta badan hababka hadda la isticmaalo, iyo dhibaatada haraaga dareerayaasha sunta ah ayaa xaddiday isticmaalka alaabada soo saarista, taasoo keentay badqabka cuntada iyo dhibaatooyinka wasakhowga deegaanka.Soo saarista beta-carotene ee biyaha ku milma ayaa sidoo kale la soo sheegay, laakiin milanka biyaha ee beta-carotene waa mid liidata, sida caadiga ah iyada oo la kaashanayo enzymes, markaa kharashku waa sarreeyaa codsigana waa liitaa.Marka la barbardhigo habka soo-saarka caadiga ah, habka soo-saarka ultrasonic wuxuu leeyahay faa'iidooyinka fudud, heerka sare ee saarista iyo wakhtiga gaaban ee hawlgalka.Sidaa darteed, sida hab cusub oo lagu soo saaro beta-carotene aalkolo-milmi leh, soo saarista ultrasonic waxay leedahay rajooyin codsi oo wanaagsan oo ku saabsan goobtan.
Isticmaalka beta-carotene
Sida nooc ka mid ah midabka saliidda lagu milmo, beta-carotene ayaa si diiran u soo dhaweeyay warshadaha cuntada sababtoo ah midabkeedu wuxuu dabooli karaa dhammaan hababka midabka casaanka ilaa jaalaha sababtoo ah diiradda kala duwan.Waxay aad ugu habboon tahay horumarinta badeecooyinka saliidda leh iyo borotiinka, sida margarin, badeecooyinka la safeeyey saxarka kalluunka, khudradda, baasto-cuntooyinka degdega ah iyo wixii la mid ah.
