BACKGROUND

Treating the exterior surface of plant material with a coating of an exogenous material can result in various problems. One such problem is that topical coatings are susceptible to degradation through exposure to the environment. Furthermore, once topically coated onto the exterior surface of plant material, the exterior surface of plant material may lose some of the coating over time due to friction with other plant material, or through contact with packaging materials. Topical coatings may also discolor the plant material making it appear unattractive or unnatural to a potential purchaser. Topical coatings typically involve flavoring and/or nutrient variations due to improper coating levels. The foregoing problems are avoided in certain instances by at least partially containing at least one exogenous vitamin and/or at least one exogenous mineral within the interior of the plant material. It is therefore desirable to provide a plant material comprising at least one exogenous vitamin and/or at least one exogenous mineral at least partially contained therein and methods for making and using the same.

An“aqueous dispersion” refers to particles distributed throughout a medium of liquid water, e.g., as a suspension, a colloid, an emulsion, a sol, etc. The medium of liquid water may be pure water, or may be a mixture of water with at least one solvent, at least one additive and/or or at least one carrier. In certain embodiments, the liquid medium comprises triacetin. Stomata are pores found in the epidermis of leaves, stems and other plant organs that facilitate gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening. Without being bound to any particular theory, it is believed that stomata open in response to increases in the osmolality of the guard cells. These increases in osmolality are followed by the movement of water into the guard cells, which increases their volume and opens the stomata. Stomatal closure occurs in the opposite manner; as the osmolality of guard cells is reduced, their volume decreases. Disclosed are methods for controlling stomatal opening and closure for purposes of at least partially encapsulating at least one exogenous vitamin and/or at least one exogenous mineral in one or more pores of a plant material.

According to certain illustrative embodiments, without being bound to any particular theory, opening the pores of the plant material includes increasing the volume of guard cells by transport of liquid across the guard cell membrane. The liquid acts to increase the volume of the guard cells which opens the stomata, allowing for greater stomatal conductance.
