Question
A pharmaceutical company wants to extract an ingredient from pomace supplied by a certain food processing plant. What are two methods they might choose to use? How could different criteria and/or constraints affect the decision on how to extract the material? In three to five sentences, describe two methods, including one criterion and one constraint that would affect extraction methods.

The pharmaceutical company could use solvent extraction and supercritical fluid extraction as methods to extract the ingredient from pomace.
1. **Solvent Extraction:** This method involves using a solvent, typically ethanol or hexane, to dissolve the desired compounds from the pomace. A criterion influencing this method could be the solubility of the target compound, while a constraint could be safety regulations regarding the use of certain solvents, as well as their environmental impact.
2. **Supercritical Fluid Extraction (SFE):** In this method, supercritical CO2 is utilized as the solvent, providing efficient extraction at lower temperatures. A criterion for this method might be the thermal sensitivity of the ingredient, as SFE is gentler on heat-sensitive compounds. However, a constraint could be the high initial cost of equipment necessary for maintaining supercritical conditions, which might limit the feasibility for large-scale extraction.
