Effects of Temperature, pH-value, and Light on Stability of Anthocyanin in Blueberry Juice
The effects of temperature, pH - value, and light source on the stability of anthocyanin in the blueberry juice were studied in this paper. The results showed that anthocyanin maintained its red color only in acidic circumstance, but was not stable in alkaline circumstance. Blueberry juice anthocyanin faded faster in natural light than in dark condition. Blueberry juice anthocyanin had a higher stability at the temperature of 60 T. After being heated for 4 hours, the residual rate of anthocyanin stayed above 80%.
