Some changes in physiological and biochemical properties of Musa paradisiaca and Musa acuminata AA banana peel during ripening harvested in Tien Giang Province, Viet Nam

The objective of this study was to determine some physiological properties (mass ratio, moisture) and biochemical properties (the content of the chlorophyll, carotenoids and the total polyphenol (TPC)) of Musa paradisiaca and Musa acuminata AA banana varieties peel, which were harvested in Tien Giang province, Vietnam at 03 stages of ripeness (I, III and VI in the color index 08 ripeness of banana). The results showed that, the ripening from I to VI maturity had a significant effected on the mass ratio, the moisture, the chlorophyll, the carotenoids and the TPC in 02 banana varieties peel and following different trends. The mass ratio and the moisture decreased, the chlorophyll and the carotenoids content recorded as opposite trends with degradation of chlorophyll and synthesis of carotenoids occured simultaneously, the most specially, the TPC increased and reached to maximum value at III maturity and decreased after. Results suggest that two banana varieties peel could be effectively used for extraction of polyphenol compounds in the future.
