Fang and Bhandari (2011) also studied the effects of temperature and aw on stability of bayberry and reported that best condition to minimize of anthocyanin was temperature below 25 C and aw below 0.33.
Evaluation of the stability of anthocyanins submitted to a temperature of 25 C in the presence and absence of light showed that samples exposed to light have higher anthocyanin content than control sample; consequently encapsulation process could successfully stabilize anthocyanins against light (Fig. 4).
In the absence of light, there was no significant difference between different wall materials in anthocyanin content while, in the presence of light, MD+GA showed the highest anthocyanin content. Burin et al. (2011) evaluated Cabernet Sauvignon anthocyanin stability in relation to temperature, light and also showed that light is an important accelerating factor in the degradation of anthocyanins.
In addition, Janna et al. (2007) reported that when exposed to light at 25 C, anthocyanins showed a significant decrease in the pigment content, with a reduction of more than 50% on the third day of exposure.
