Question

A pharmaceutical company wants to extract an ingredient from pomace supplied by a certain food processing plant. What are two methods they might chose 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.(4 points)

Answer 1

They might use a conventional solvent extraction (e.g., food‑grade ethanol with heat/ultrasound) or a supercritical CO2 extraction. Solvent extraction is simple and can give high yields for polar and mid‑polarity compounds, but a key constraint is solvent residues and disposal plus regulatory limits on residual solvents. Supercritical CO2 gives very clean, solvent‑free extracts and is gentler on heat‑sensitive molecules (a useful criterion when purity and stability matter), but it is constrained by high capital cost and the need for high‑pressure equipment. The final choice will hinge on criteria like required purity/yield and constraints such as budget, throughput, and regulatory/safety limits.
