as it dries up the water content goes with the colour of the fruit. so it changes colour
i guess as the water content of the fruit evaporates it takes the color with it so the color change
No, cherries do not ripen after picking. They will not get sweeter or change color once they have been harvested.
berries
Blueberries transform from their original blue color to a vibrant red hue through a natural process called anthocyanin accumulation. This occurs as the berries ripen and the levels of anthocyanin, a type of pigment, increase in the fruit, causing the color change.
Not all mangos change color as they ripen, so the best way to tell if mangos are ripe is to squeeze them gently.
Peppers turn white as they ripen due to a process called "decoloration," where the green pigments in the pepper break down and the white color underneath becomes more visible. This change in color is a natural part of the ripening process in some pepper varieties.
Green peppers are actually unripe when they are green. As they ripen, they change color to yellow, orange, or red, depending on the variety.
Green bell peppers are actually unripe versions of the pepper. As they ripen, they change color to yellow, orange, or red.
Banana peppers turn red when they are left on the plant longer and ripen. This change in color is a natural process as the peppers mature.
Usually anywhere from the middle of August until the middle of September, once the berries are dark purple or almost black, showing no red. I have read, once they reach that point, you should let them 'over-ripen' for another week to get the best flavor. Some parts of the trees, depending on height and exposure to elements will ripen quicker, so you can continue to pick as they continue to ripen. In 2009, I picked berries from late August to late September to make jelly with and did not notice any difference in the flavor of the jelly.
however long it takes, god!
Jalapenos turn orange as they ripen due to the presence of a pigment called carotenoids. This change in color indicates that the jalapeno is becoming sweeter and less spicy.
