Effects of location planting on the quality and antioxidants of ‘Namwa’ bananas produced in northeastern Thailand

‘Namwa’ banana (Musa spp.) is an economically important fruit in Thailand.
It also grows naturally and randomly in the warm and humid tropical climate everywhere in the country.
However, the banana cultivators in the northeast of Thailand deal with dry conditions that dramatically affect growth, yield, fruit quality and antioxidant content.
The ‘Namwa’ banana has high levels of antioxidants and benefits for the body.
The objective of this study was to investigate the effects of location planting on the quality and antioxidants of ‘Namwa’ bananas.
Experiments were conducted in Loei and Udon Thani Provinces, northeast of Thailand.
Samples were randomly collected in cool and hot seasons.
Fruit quality and antioxidant status were evaluated between the 10^th month after transplantation.
The results showed that the skin color changes of bananas were expressed as L*, a*, and b* values.
These values increased gradually during storage in the skin of the banana, indicating the color changed from green to yellow.
The firmness of all processes tended to decrease during storage.
The amounts of soluble solids tended to increase.
In contrast, the amount of titrated acid was reduced.
That phenolic, flavonoid, lycopene, and -carotene content were not different between two locations.
Moreover, tannin content in ‘Namwa’ bananas was highest in Udon Thani Province.
