What You Need to Know
Proteolytic enzymes such as Aspergillus oryzae proteases hydrolyze myofibrillar proteins into peptides, while lipases from Penicillium roqueforti cleave triglycerides into free fatty acids. These reactions occur optimally at 20–35 °C under low‑oxygen conditions, producing umami‑rich peptides and aroma‑contributing fatty acids.
