Elikadura-koloratzaileak elikadura industrian geroz eta gehiago erabiltzen diren gehigarriak dira. Baina hauen erabilera mugatua dago haurren osasunean izan ditzakeen eraginengatik. Horien artean Allura gorria (E-129) dago, azken urte hauetan aztertua izan dena. Hori dela eta, elikagaietan dagoen koloratzaile kantitatea determinatzea beharrezkoa da.
Lan honetan, paper euskarri bidezko analisian oinarritutako metodo berri bat bilatu da. Jarraian, diseinu esperimentalaren bidez optimizazioa egin da, non 4 parametro optimizatu diren, permanentearen tamaina eta kolorea, zirkunferentziaren diametroa, borobilera botatako disoluzioaren bolumena eta argazkiak hartzeko denbora. Paper euskarri bidezko analisia aztertzen den lehenengoa aldia denez, script berri bat garatu da argazkiak prozesatzeko eta datuak lortu ahal izateko.
Bukatzeko, ezin izan da metodo berri hau balidatu alarma egoeraren ondorioz lan esperimentalaren etetea dela eta.

Food dyes are increasingly used additives in the food industry, but its use is limited by the effects they can have on children's health. Among them we can find the Allure Red (E-129), that has been studied in recent years. Therefore, it is necessary to determine the amount of colorant in the food.
In this work, a new method based on paper-based analysis has been used. Subsequently, the optimization was carried out using the experimental design, where four parameters were optimized, the size and colour of the permanent, the diameter of the circumference, the volume of the solution that has been thrown around and the time of photographing. As it is the first time that these analysis has been analysed on paper, a new script has been developed to process the photographs and obtain data.
Finally, this new method could not be validated due to the interruption of the experimental work as a consequence of the alarm state. | es_ES |
