Identification of Starch in Food Products

Nastya conducted an experiment in the laboratory to test various food products for the presence of starch. She recorded the results in her notebook. Based on Nastya's notes, let's determine which product showed the presence of starch after adding one drop of a 5% iodine solution.

According to Nastya's observations:

1. Mushroom soup: The color of the mushroom soup did not change after adding the iodine solution. This suggests that starch was not detected in the mushroom soup.

2. Kefir: The kefir acquired a yellowish tint after the addition of the iodine solution. This indicates the presence of starch in the kefir.

3. Peanut butter diluted with water: The color of the diluted peanut butter did not change after adding the iodine solution. This suggests that starch was not detected in the diluted peanut butter.

4. Lentil soup: The lentil soup turned black after the addition of the iodine solution. This indicates the presence of starch in the lentil soup.

Therefore, based on Nastya's observations, she detected the presence of starch in kefir and lentil soup after adding one drop of a 5% iodine solution.

Please note that the information provided is based on the given scenario and the observations recorded by Nastya.
