Abstract
BACKGROUND:
OBJECTIVE:
Decoctions of the fruit were prepared and the effect of temperature, time and pH on oxidative stability and color parameters were evaluated.
METHODS:
To evaluate the oxidative stability the ORAC, FRAP, and DPPH methodologies and the quantification of phenols and anthocyanins by spectrophotometric tests were developed, while colors parameters were determined using a colorimeter and UV- VIS spectrums.
RESULTS:
Rising the temperature from 60 to 100°C increased phenol content, FRAP and ORAC values up to 724.24 mg gallic acid/L, 978.51 mg ascorbic acid/L and 14172
CONCLUSION:
The content of phenols increased with temperature, increasing the antioxidant capacity, however the anthocyanins were degraded above 80°C and 20 minutes of processing.
