What You Need to Know
Roasting shea nuts at 40–60 °C for 30–45 min softens the kernel, breaking down cell walls and releasing triglycerides. Marula seeds are dry‑pressed at 50–70 °C for 2–3 h, where heat and pressure further disrupt seed structure, allowing oil to flow. Both processes preserve high levels of oleic acid and tocopherols, which contribute to antioxidant activity and a buttery flavor profile.
