Values are expressed in means ± standard deviation (n = 5).
Data with the same letter are similar statistically in the Tukey test (p < 0.05).
Itaconic, acetic, glyoxylic, and lactic acids were not detected.
Commercial juices and pulps could be processed to improve the characteristics of the final product.
