How do the nutritional values of bananas change as they ripen?
Unripe bananas are hard with thick skins and an unmistakeable raw flavour. As they ripen they shrink slightly, the skins become thinner, and the fruit becomes softer and sweeter; the raw flavour goes away.
How does the nutritional composition of the fruit change during the transformation?
Best Answer
Starch content and sweetness: Bananas become sweeter as they ripen because the starch is broken down. An unripe banana is full of complex carbohydrates, but as it ripens, these are broken down into simple sugars which is why riper bananas are sweeter. The lower starch content and higher sugar content also means that the banana is digested more quickly, so it becomes a slightly higher GI food as it ripens.
Antioxidant levels: Riper bananas also have higher levels of antioxidants. The brown spots on the skin are formed when the chlorophyll breaks down into antioxidants. These are very good for your body as they help prevent cell damage.
Calorie count: As the banana ripens, the calorie count stays the same. Even though the nutrients change, all carbohydrates contain 4 calories per gram so the total remains the same
Vitamins and minerals: As the fruit ripens, the micronutrients tend to decrease. Water soluble vitamins like vitamin C, folic acid and thiamin decrease. But the banana will still have a lot of potassium. You can store a ripe banana in the fridge to prevent some of these nutrients from being lost.

Does the nutrition in a banana change as it ripens?
A: Nutrient content does change slightly as fruit ripens. As a banana turns yellow, its levels of antioxidants\u2014substances that seem to protect against cancer and heart disease\u2014increase somewhat, so you may be missing a small nutritional benefit.Do unripe bananas have the same nutritional value?
Green bananas may provide some additional nutrients and benefits that yellow bananas do not. They're rich in resistant starch and pectin, which are filling, improve digestive health, and help lower blood sugar levels.At what stage are bananas more nutritious?
Just as the starch has broken down into sugar, chlorophyll has taken a new form as well. This breakdown of chlorophyll is the reason why antioxidant levels increase as bananas age. So a fully brown banana is an antioxidant powerhouse.What happens to the carbs in a banana as it ripens?
The carb composition of bananas changes drastically during ripening. The main component of unripe bananas is starch. Green bananas contain up to 80% starch measured in dry weight. During ripening, the starch is converted into sugars and ends up being less than 1% when the banana is fully ripe (2).What Will Happen if You Eat 2 Bananas a Day

Answer 2
In unripe bananas a lot of the starch is made up of resistant starch. Green bananas may contain between 35.14 and 45.87% of resistant starch (in Thai bananas) which varies depending on the variety of banana.
