Colour changes and instability of antocyanins

Popis výsledku v původním jazyce

Anthocyanins are plant pigments of special interest for their colour changes in different acidic media. In the food industry they are used as colourants and as antioxidants, in food they play the role of natural antioxidants and historically they were used in textile dyeing. The advantage of anthocyanins is their medical safety, easy availability of renewable resources, and the possibility of recovery of canning and wine pressings. The disadvantage is a colour instability and susceptibility to physicaland chemical conditions that limits their use and further processing. This study looks at testing the rate of decomposition of anthocyanins in the juice of blueberry, elderberry and extract of blue grape vine remnants by alkaline medium exposure, high temperatures and UV radiation and discusses the suitability of their use in textile dyeing.
