Why is the pH of plantain differs day by day?

The pH of plantains can vary day by day due to several factors, including changes in ripeness, environmental conditions, and microbial activity. As plantains ripen, organic acids break down and sugars increase, affecting their acidity and, consequently, their pH. Additionally, fluctuations in temperature, humidity, and exposure to sunlight can influence the biochemical processes within the fruit. These factors contribute to the daily variation in pH levels of plantains.
