Anthocyanins are responsible for the characteristic and attractive colour present in fruit products such as juices and beverages. As natural pigments, having the acceptance of consumers, they are often used as food colorants. The significant adventage of anthocyanins is their health-promoting properties, such as antioxidant, cardioprotective and antivirus activity. The main problem with anthocyanins is their high lability toward exogenic factors. High temperature treatments can affect anthocyanin content in fruit based food products. Thermal degradation of anthocyanin pigments can have dramatic impact on color quality and may also affect nutritional properties by decreasing the amount of bioactive compounds.
