G\u0131da renklendiricileri a\u015fa\u011f\u0131daki \u00f6zelliklere sahiptir<\/strong><\/p>\n

(1) Do\u011fal renklendiriciler daha do\u011fal ve yumu\u015fak tonludur, bu da insan\u0131 ve do\u011fay\u0131 birbirine yakla\u015ft\u0131rabilir, ancak do\u011fal renklendiricilerin boyama kabiliyeti zay\u0131ft\u0131r ve boyama tekd\u00fcze de\u011fildir; sentetik renklendiriciler parlak renklidir ve t\u00fcketiciler, \u00f6zellikle \u00e7ocuklar ve gen\u00e7ler taraf\u0131ndan memnuniyetle kar\u015f\u0131lan\u0131r.<\/p>\n

(2) Do\u011fal renklendiriciler genellikle bitki ve hayvanlar\u0131n kendilerinden gelir, insan v\u00fccudu \u00fczerinde toksik yan etkileri yoktur, sentetik renklendiricilere k\u0131yasla g\u00fcvenlik daha y\u00fcksektir, ancak sentetik renklendiriciler g\u00fc\u00e7l\u00fc renklendirme g\u00fcc\u00fcne sahiptir, \u00e7\u00f6z\u00fcnmesi kolayd\u0131r, kokusuz ve tats\u0131zd\u0131r, ucuzdur ve di\u011fer avantajlar\u0131 vard\u0131r ve pop\u00fclerdir.<\/p>\n

(3) Do\u011fal renklendiricilerin \u00e7o\u011fu \u0131\u015f\u0131\u011fa ve \u0131s\u0131ya, metale, aside ve alkaliye, oksidana duyarl\u0131d\u0131r, bu ko\u015fullar alt\u0131nda karars\u0131zd\u0131r, renk tonu b\u00fcy\u00fck \u00f6l\u00e7\u00fcde de\u011fi\u015fecektir ve sentetik renklendiriciler bu eksikli\u011fi telafi edebilir.<\/p>\n

(4) Baz\u0131 do\u011fal renklendiriciler do\u011fal antioksidanlar ve do\u011fal koruyucular olarak kullan\u0131labilir. Sentetik antioksidanlar\u0131n ve koruyucular\u0131n g\u00fcvenlik sorunlar\u0131 nedeniyle, giderek daha fazla t\u00fcketici do\u011fal antioksidanlar ve koruyucular kullanma e\u011filimindedir.<\/p>\n

(5) \u00c7o\u011fu do\u011fal renklendirici ayn\u0131 zamanda hem besin de\u011ferine hem de farmakolojik etkilere sahiptir ve g\u0131da renklendiricileri t\u0131p alan\u0131nda da b\u00fcy\u00fck uygulama olanaklar\u0131na sahiptir. \u00d6rne\u011fin, k\u0131rm\u0131z\u0131 lahana pigmentinin insan kalp hastal\u0131\u011f\u0131 ve ateroskleroz \u00fczerinde iyi bir etkisi vard\u0131r.<\/p>\n

G\u0131da renklendiricilerinin optimizasyonunu etkileyen fakt\u00f6rler<\/strong><\/p>\n

I. G\u0131da renklendiricilerinin g\u00fcvenlik fakt\u00f6rleri<\/strong>
\nToksikologlar ve analitik kimyagerler \u00e7al\u0131\u015fmaya devam ettik\u00e7e, bir\u00e7ok sentetik renklendirici fark edilmi\u015f, sentetik renklendiricilerin dezavantajlar\u0131 yava\u015f yava\u015f ortaya \u00e7\u0131km\u0131\u015ft\u0131r. Sentetik renklendiricilerin \u00e7o\u011fu azo bile\u015fikleridir ve bir\u00e7o\u011fu insan v\u00fccudunda metabolize olarak toksik yan etkileri olan \u03b1-naftilamin ve \u03b2-naftilamin \u00fcretebilir. Sentetik renklendiricilerin g\u00fcvensiz fakt\u00f6rleri g\u00f6z \u00f6n\u00fcnde bulundurularak, bu sentetik g\u0131da renklendiricileri i\u00e7in yurti\u00e7inde ve yurtd\u0131\u015f\u0131nda kat\u0131 yasalar ve d\u00fczenlemeler form\u00fcle edilmi\u015ftir ve \u00c7in ayr\u0131ca \u00e7e\u015fitli b\u00f6lgelerde \u00fcretilen ve kullan\u0131lan g\u0131da renklendiricileri \u00fczerinde \u00f6rnekleme ara\u015ft\u0131rmalar\u0131 yapm\u0131\u015ft\u0131r.<\/p>\n

Bir\u00e7ok maddenin belirli bir al\u0131m seviyesini a\u015fmas\u0131 halinde belirli toksik yan etkiler g\u00f6sterece\u011fini biliyoruz ve ayn\u0131 \u015fekilde g\u0131da renklendiricileri de istisna de\u011fildir. Renklendirici madde, devlet taraf\u0131ndan izin verilen kapsamda kullan\u0131ld\u0131\u011f\u0131 s\u00fcrece, genellikle insan sa\u011fl\u0131\u011f\u0131na zararl\u0131 de\u011fildir. Bununla birlikte, \u015fu anda bir\u00e7ok \u00e7e\u015fit g\u0131da renklendirici madde bulunmaktad\u0131r ve renklendirici madde eklenmi\u015f g\u0131da \u00fcr\u00fcnleri her yerde bulunabilir, bu nedenle belirli bir g\u0131da renklendirici maddenin eklenen miktar\u0131 nitelikli olabilir, ancak t\u00fcketiciler tekrar tekrar birden fazla renklendirici madde veya birden fazla renklendirici madde t\u00fckettiklerinde yine de toksik yan etkilere sahip olacaklard\u0131r.<\/p>\n

II. G\u0131da renklendiricilerinin stabilize edici fakt\u00f6rleri<\/strong>
\nDo\u011fal renklendiricileri ara\u015ft\u0131rman\u0131n d\u00f6n\u00fcm noktas\u0131, kalitelerini ve kararl\u0131l\u0131klar\u0131n\u0131 art\u0131rmakt\u0131r ve \u00e7e\u015fitli \u00fclkelerden kimyagerler bu konuda bir\u00e7ok ara\u015ft\u0131rma yapm\u0131\u015ft\u0131r. Genellikle, do\u011fal renklendiricilerin stabilitesi a\u015fa\u011f\u0131daki y\u00f6nlerden incelenmektedir.<\/p>\n

(1) I\u015f\u0131k fakt\u00f6r\u00fc. Do\u011frudan g\u00fcne\u015f \u0131\u015f\u0131\u011f\u0131 renk de\u011fi\u015fimlerinde renklendirici maddeyi ifade eder, \u00f6rne\u011fin klorofil bitki yapraklar\u0131nda ve g\u00f6vdelerinde yayg\u0131n olarak bulunur, \u0131\u015f\u0131\u011fa maruz kald\u0131\u011f\u0131nda ayr\u0131\u015fmas\u0131 kolayd\u0131r, stabilitesini art\u0131rmak i\u00e7in genellikle bak\u0131r sodyum tuzundan yap\u0131l\u0131r.<\/p>\n

(2) S\u0131cakl\u0131k fakt\u00f6r\u00fc. Renklendirici maddenin \u0131s\u0131 direnci g\u00f6z \u00f6n\u00fcne al\u0131nd\u0131\u011f\u0131nda, safran sar\u0131s\u0131 pigmenti zay\u0131f \u0131s\u0131 direncine sahiptir, y\u00fcksek Vc i\u00e7eren g\u0131dalarda kullan\u0131l\u0131rsa stabilitesini art\u0131rabilir.<\/p>\n

(3) Asit-baz fakt\u00f6r\u00fc. Rengin asidik veya alkali ko\u015fullar\u0131ndaki renklendirici maddenin yan\u0131 s\u0131ra de\u011fi\u015fikliklerin stabilitesini ifade eder, \u00f6rne\u011fin \u03b2-karoten havu\u00e7 ve alglerde yayg\u0131n olarak bulunur, zay\u0131f alkali ko\u015fullarda daha kararl\u0131d\u0131r, ancak asidik ko\u015fullarda ayr\u0131\u015fmas\u0131 kolayd\u0131r, az miktarda Vc eklerseniz stabilitesini art\u0131rabilir; ku\u015fburnu renklendirici ajan rengi \u00e7\u00f6zeltinin pH de\u011feri ile de\u011fi\u015fir, asidik ko\u015fullar k\u0131rm\u0131z\u0131, n\u00f6tr mor, alkali stabilitesini art\u0131rabilir. Ku\u015fburnu pigmentinin rengi \u00e7\u00f6zeltinin pH de\u011ferine g\u00f6re de\u011fi\u015fir, asidik durumda k\u0131rm\u0131z\u0131, n\u00f6tr durumda mor ve alkali durumda mavidir.<\/p>\n

(4) Metal iyonlar\u0131. Genellikle bak\u0131r iyonu, sodyum iyonu, magnezyum iyonu, demir iyonu ve benzerlerine sahiptir, gardenya pigmentinin demir iyonuna tolerans\u0131 g\u00fc\u00e7l\u00fc de\u011fildir, baz\u0131 metal iyonlar\u0131 renklendiricinin rengini de\u011fi\u015ftirmesine ve hatta renginin solmas\u0131na neden olabilir ve baz\u0131 metal iyonlar\u0131, klorofil gibi baz\u0131 renklendirici ajan stabilitesini art\u0131rabilir, bak\u0131r sodyum tuzunun stabiliteyi art\u0131rmas\u0131n\u0131 sa\u011flar.<\/p>\n

(5) antioksidan ve indirgeyici ajan fakt\u00f6rleri. Yayg\u0131n olarak kullan\u0131lan antioksidanlar Vc, sodyum tiyos\u00fclfatt\u0131r, \u00f6rne\u011fin, \u0131s\u0131 direnci nedeniyle aspir sar\u0131 pigmenti iyi de\u011fildir, metal iyonlar\u0131na duyarl\u0131d\u0131r, az miktarda Vc eklemek stabilitesini b\u00fcy\u00fck \u00f6l\u00e7\u00fcde art\u0131rabilir.<\/p>\n

(6) S\u00fckroz, \u015fap, tartarat fakt\u00f6r\u00fc gibi baz\u0131 bile\u015fikler. \u00d6rne\u011fin, stabilitesinden sonra \u015fap ve tartarik asit tuzu ilavesindeki sar\u0131 pigment \u00f6nemli \u00f6l\u00e7\u00fcde art\u0131r\u0131labilir.<\/p>\n

(7) Baz\u0131 renklendiriciler ve stabilitesinin ba\u015fka bir renklendirici kombinasyonu da geli\u015ftirilebilir, \u00f6rne\u011fin pancar k\u0131rm\u0131z\u0131s\u0131 ve pancar k\u0131rm\u0131z\u0131s\u0131 gibi iki renklendirici, bariz art\u0131\u015f\u0131n stabilitesinden sonra birbirleriyle birle\u015ftirilebilir.<\/p>\n

(8) \u00c7\u00f6z\u00fcn\u00fcrl\u00fck fakt\u00f6rleri. \u00dcz\u00fcm kabu\u011fu pigmenti ve perilla pigmenti suda \u00e7\u00f6z\u00fcnen renklendiricilerdir, k\u0131rm\u0131z\u0131 pirin\u00e7 pigmenti ve karakafes pigmenti ise ya\u011fda \u00e7\u00f6z\u00fcnen renklendiricilerdir. Ayr\u0131ca, renklendiricinin tuz direnci ve mikrobiyal direnci de renklendiricinin kendisi \u00fczerinde belirli bir etkiye sahiptir.<\/p>","protected":false},"excerpt":{"rendered":"
