5\u2019inci Uluslararas\u0131 Avrasya Do\u011fal Beslenme, Sa\u011fl\u0131kl\u0131 Ya\u015fam ve Spor Kongresi, Gazi \u00dcniversitesinde ger\u00e7ekle\u015fti. \u0130stanbul Teknik \u00dcniversitesi G\u0131da M\u00fchendisli\u011fi B\u00f6l\u00fcm\u00fc \u00d6\u011fretim G\u00f6revlisi Do\u00e7. Dr. Esra \u00c7apano\u011flu G\u00fcven, kongrede T\u00fcrkiye dahil toplam 19 farkl\u0131 \u00fclkede sat\u0131lan propolis i\u00e7erikli \u00fcr\u00fcnlerin i\u00e7erik ve etken maddelerini analiz ettiklerini belirtti. Ara\u015ft\u0131rma sonu\u00e7lar\u0131n\u0131 payla\u015fan G\u00fcven, \u00f6zellikle su bazl\u0131 iddias\u0131 ile sat\u0131lan \u00fcr\u00fcnlerde b\u00fcy\u00fck bir sorun oldu\u011funu ve hi\u00e7birinin etiketinde beyan edilen miktarda propolis i\u00e7ermedi\u011fini tespit ettiklerini s\u00f6yledi. G\u00fcven sunumunda, propolisin re\u00e7inemsi bir ar\u0131 \u00fcr\u00fcn\u00fc oldu\u011funu ve ham halde insan v\u00fccudu taraf\u0131ndan sindirilemedi\u011fini belirtti. Propolisin fenolik ve flavonoid maddelerden meydana geldi\u011fini ve g\u00fc\u00e7l\u00fc bir antioksidan oldu\u011funu, insanlar\u0131n bu \u00fcr\u00fcn\u00fc sa\u011fl\u0131k i\u00e7in t\u00fcketti\u011fini s\u00f6yleyen G\u00fcven, ancak propolisin tebli\u011fi yani kodeksi olmad\u0131\u011f\u0131 i\u00e7in bu konuda piyasada b\u00fcy\u00fck bir sahtekarl\u0131k sorunu oldu\u011funu ifade etti. T\u00fcrkiye dahil t\u00fcm d\u00fcnyadan 130 propolis i\u00e7erikli \u00fcr\u00fcn analiz ettiklerini belirten G\u00fcven, bu \u00fcr\u00fcnlerin 33\u2019\u00fcn\u00fcn su bazl\u0131 propolis iddias\u0131 ile sat\u0131ld\u0131\u011f\u0131n\u0131 ancak bu \u00fcr\u00fcnlerin neredeyse hi\u00e7 propolis i\u00e7ermedi\u011fini tespit ettiklerini s\u00f6yledi. Bu 33 \u00fcr\u00fcn\u00fcn 27\u2019sinin ise T\u00fcrkiye\u2019de sat\u0131ld\u0131\u011f\u0131n\u0131 ve \u00f6zellikle T\u00fcrkiye\u2019de bu konuda b\u00fcy\u00fck bir bo\u015fluk oldu\u011funu ve bu sahte \u00fcr\u00fcnler nedeniyle t\u00fcketicinin kand\u0131r\u0131ld\u0131\u011f\u0131n\u0131 belirten G\u00fcven, baz\u0131 su bazl\u0131 \u00f6rneklerin etiketinde yaz\u0131lmayan ama insan sa\u011fl\u0131\u011f\u0131 a\u00e7\u0131s\u0131ndan tehlikeli olabilecek maddeler i\u00e7erdi\u011fini de ekledi. Bu durumun acil olarak kontrol alt\u0131na al\u0131nmas\u0131 gerekti\u011fini belirten G\u00fcven, Tar\u0131m Bakanl\u0131\u011f\u0131 taraf\u0131ndan izin verilen takviye edici g\u0131da s\u0131n\u0131f\u0131nda olan bu \u00fcr\u00fcnler i\u00e7in acilen Propolis Tebli\u011fi\u2019nin olu\u015fturulmas\u0131 gerekti\u011fini s\u00f6yledi.<\/p>\n
“Propolis sadece su ile \u00f6z\u00fctlenmez”<\/p>\n
G\u00fcven, \u201cPropolis do\u011fal yap\u0131s\u0131 gere\u011fi ham halde balmumu ile kar\u0131\u015f\u0131kt\u0131r ve sindirilebilmesi i\u00e7in \u00f6z\u00fctlenmesi gerekir ama bu i\u015flem do\u011fru yap\u0131lmazsa son \u00fcr\u00fcnde propolis bulundu\u011fundan bahsedemeyiz. Propolis glikol, etanol, gliserol gibi alkol ve t\u00fcrevi maddelerin bulundu\u011fu sulu \u00e7\u00f6zgenler ile \u00f6z\u00fctlenebilir ama sadece su ile \u00f6z\u00fctlenmesi m\u00fcmk\u00fcn de\u011fildir. E\u011fer su ile \u00f6z\u00fctlenebilseydi, her ya\u011fmur ya\u011fd\u0131\u011f\u0131nda kovanda propolis eriyip giderdi yani ar\u0131lar\u0131n petek g\u00f6zleri yok olurdu, kovanda delikler meydana gelirdi. Bu ara\u015ft\u0131rman\u0131n sonucu da bu durumu do\u011fruluyor. Hem \u00fclkemizden hem de yurt d\u0131\u015f\u0131ndan toplam 19 farkl\u0131 \u00fclkeden toplad\u0131\u011f\u0131m\u0131z 130 propolis i\u00e7erikli \u00fcr\u00fcnde toplam fenolik, flavonoid madde, kuru madde, Ph, antioksidan kapasitesi ve fenolik madde profili analizlerini ger\u00e7ekle\u015ftirdik. Ara\u015ft\u0131rmada incelenen \u00fcr\u00fcnler propolisin su, ya\u011f, etanol, glikol, gliserol gibi maddelerle haz\u0131rlanm\u0131\u015f \u00f6z\u00fct formlar\u0131yd\u0131. \u00c7al\u0131\u015fman\u0131n sonucunda su bazl\u0131 propolis iddias\u0131 ile sat\u0131lan \u00fcr\u00fcnlerin \u00e7ok d\u00fc\u015f\u00fck antioksidan kapasiteye sahip olduklar\u0131n\u0131 tespit ettik. Ayr\u0131ca propolisin i\u00e7erisinde bulunmas\u0131 gereken etken maddelerin hi\u00e7birine de maalesef rastlamad\u0131k. \u00c7\u00fcnk\u00fc propolisin tek ba\u015f\u0131na su ile \u00f6z\u00fctlenmesi m\u00fcmk\u00fcn de\u011fildir. Propolisin \u015fifal\u0131 olan ve bitkilerin \u00f6z\u00fcnden gelen re\u00e7ine k\u0131sm\u0131 yani fenolik ve flavanoidler sadece etanol, glikol, gliserol gibi maddelerde \u00e7\u00f6z\u00fcn\u00fcr \u00f6zelliktedir. Dolay\u0131s\u0131yla ekstraksiyon i\u015fleminde bu \u00e7\u00f6zgen maddelerin kullan\u0131lmas\u0131 \u015fartt\u0131r\u201d ifadelerini kulland\u0131.<\/p>\n
“\u00dcr\u00fcnler analiz edilerek denetim alt\u0131na al\u0131nmal\u0131”<\/p>\n
Piyasada su bazl\u0131 propolis ad\u0131 alt\u0131nda sat\u0131lan pek \u00e7ok \u00fcr\u00fcn oldu\u011funun ve bu konuda b\u00fcy\u00fck bir sahtekarl\u0131k yap\u0131ld\u0131\u011f\u0131n\u0131n alt\u0131n\u0131 \u00e7izen G\u00fcven, “Su bazl\u0131 propolis olarak sat\u0131lan \u00fcr\u00fcnlerde etiketlerinde sadece su ve propolis bulundu\u011fu iddia edilmesine ra\u011fmen ba\u015fka maddeler de tespit ettik. Bu maddeler, etikette belirtilmedi\u011fi i\u00e7in t\u00fcketiciler a\u00e7\u0131s\u0131ndan b\u00fcy\u00fck risk arz ediyor. T\u00fcketiciler bu anlamda fayda g\u00f6receklerini d\u00fc\u015f\u00fcnd\u00fckleri bir \u00fcr\u00fcn\u00fc sat\u0131n alarak kand\u0131r\u0131l\u0131yor. Propolis kodeksi bir an \u00f6nce haz\u0131rlanmal\u0131 ve piyasadaki \u00fcr\u00fcnler analiz edilerek denetim alt\u0131na al\u0131nmal\u0131. Bu noktada t\u00fcketiciler de dikkatli olmal\u0131lar, sat\u0131n ald\u0131klar\u0131 \u00fcr\u00fcn\u00fcn men\u015feini, nas\u0131l \u00fcretildi\u011fini, nas\u0131l \u00f6z\u00fctlendi\u011fini yani nas\u0131l ekstrakte edildi\u011fini mutlaka sorgulamal\u0131lar. En az\u0131ndan etikette ekstraksiyon yani \u00f6z\u00fctleme a\u015famas\u0131nda glikol, gliserol, etanol gibi maddelerin kullan\u0131ld\u0131\u011f\u0131 \u00fcr\u00fcnleri tercih etmeliler. Etanol, glikol, gliserol gibi maddeler g\u0131da ve ila\u00e7 sanayinde de kullan\u0131l\u0131r ve bir\u00e7ok g\u0131dada da zaten do\u011fal olarak bulunur. Bunlar\u0131 tehlikeli gibi g\u00f6stererek, sadece su ve boyar madde i\u00e7eren \u00fcr\u00fcnleri propolis ad\u0131 ile satabiliyorlar. T\u00fcketicilerin bilime ayk\u0131r\u0131 olan bu s\u00f6ylemlere kanmamalar\u0131 gerekir\u201d diye konu\u015ftu.<\/p>\n","protected":false},"excerpt":{"rendered":"
