Which of the following humectants aids in retaining moisture, enhances the rehydration process of hydrated foods, and assists in dissolving flavor compounds?

Explanation

Humectants are substances used to maintain moisture in food products. Mannitol is particularly effective in improving moisture retention, promoting better rehydration of hydrated foods, and facilitating the solubilization of flavor compounds, making it the correct choice. Benzoyl peroxide and nitrosyl chloride are not humectants, while sorbitol, although a humectant, is not the best option in this context.
