microwave extraction can be changed through some factors such as extraction temperature, solvent composition, and extraction time. The extraction temperature was usually studied more than other factors due to its ability to increase the efficiency of the microwave extraction.

Tsubaki et Cited by:   Further, chemicals are added to achieve certain technical effects such as preservation, color, consistency (e.g. emulsification), flavoring, sweetening, and other physical effects. Additional substances often are introduced, usually in very small amounts that are largely by­products of agriculture and packaging (indirect additives).Cited by: Extraction methods included elevated temperature sealed vessel extraction, sonication, refluxing, and Soxhlet extraction.

Extraction solvents included a low-pH (pH = ) salt mixture, a high-pH.
