Influence of Comminution Methods and Air Exposure in the Production of Melissa officinalis Mother Tincture.

These changes can ultimately lead to losses in valuable ingredients and deterioration of the final product. Consequently, in the food, cosmetics, and pharmaceutical industries, oxidation and the use of antioxidant conservatives are major considerations during processing and production.
