Banana vs Potassium Scifair Projects

Banana Nutrients

Bananas are eaten as a source of potassium. However, the amount of potassium that a banana contains may change as it ripens.

Objectives/Goals

The goals were to determine at what age of the banana contains the most amounts of potassium as well as at what age of the banana contains the least amounts of potassium.

Methods/Materials

The major materials utilized were ten bananas, distilled water, a Cardy K meter, standardized solution, and sampling sheets. The bananas were cut, pressed, and measured in a course of eight days. After each measurement, the meter was cleaned with distilled water to ensure accuracy in the results. The results were gathered as the bananas gradually ripened.

Results

On average, the bananas in the first day of experimentation contained the most amounts of potassium of 4300 ppm. However, bananans of day seven contained the least amounts of 2730 ppm. There was a drastic decrease.

Conclusions/Discussion

My conclusion was that the younger bananas will contain more amounts of potassium as opposed to the riper bananas. These results may prove beneficial to those who require the greater amounts of potassium in their daily diet. 3rd party contributor
